Thats all I got from your link OP

[rushlink01]

Is it just me, or should i expect to see the laser gun flashing as you get clocked for speeding, as its IR. Although IR is invisible to you, it'll be on your video.

Either that cop didnt clock you, or you didnt get pulled over by him?

[erkme73]

@rushlink01 It's just you.

[clickcl0ck3d]

What kind of camera/setup are you using? i was looking for a good set up like this for a while and i would love to have this set up a link or info would be much appreciated.

[tazztt1]

Since YOU were convinced that his Radar was inaccurate, you could have filed for maintenance records of THAT particular radar gun, likely finding that it was overdue for calibration, then moving to dismiss based on the failure of the PD to maintain equipment, never having to prove this with YOUR vid at all.

When asked, the officer MUST tell you ON SITE Make Model and Serial Number of the radar they're using.

There are 100 ways to beat a speeding ticket, that's just one.

[jamie381]

@tazztt1 Don't know where your from, but an officer is not required by ANY means to tell you 100% of everything. That is what your lawyer for court is paid to do. It's your Lawyer's job to get information using the court system. If you can show me a law that requires a LEO to state anything to you, then I'll yield, but this information is coming from a local county sheriff, and I couldn't find anything to prove him wrong.

[tazztt1]

@jamie381 ... If this is what you believe, it's you that will be losing cases, meanwhile, I'll be beating them. Best of luck to you my friend. They've trained you well.

[jamie381]

@tazztt1 "Does the officer have to show the radar reading to a motorist?" - "No. Some jurisdictions may have a policy to this effect however the author is not aware of any that do. Most officers will show the radar to a motorist as a courtesy if asked in a polite manner and when the officer’s and the citizen's safety is not jeopardized by doing so. If the officer did not lock the speed reading on the radar there may be no display of the speed to be viewed anyway." - FAQ by former officer

[tazztt1]

@jamie381 ... Good. If that's the way 'officers' operate, I'd have them for lunch in court. The 'accused' has a right to face their accuser AND dissect the evidence. In a case where an 'officer' (revenue agent) did not 'lock' or 'show' a radar reading, I'd WIN the case with the defense that there is insufficiant evidence, compounded by the 'officer's' failure to produce it. I'd finish with 'obstruction of justice', then file a false witness claim against the 'officer' afterward. Bad day for them

[jamie381]

@tazztt1 The next time you make a mistake I'll be sure to be right there and sue the shit out of you.. Taking your stance and putting it a purpose against you. Have fun! Again I don't know where you live, but in my state they are not required to even use radar to write you a ticket a senior officer can write you one using only math in his head. Again, it's YOUR responsiblity to prove an officer wrong. Take responsibility for your actions instead of placing off on others.

[tazztt1]

@jamie381 ... LMMFAO! Sue me, hahahaha. You clearly don't know your Constitution, or you're forgetting (or ignoring) the part where one is innocent until proven guilty and the burden of proof is on the PLAINTIFF, not the defendant. ALL tickets are illegal anyway (except in a case involving an accident) where there is no injured party. The commies have most of the public snowed I will agree, but you have NO jurisdiction over me and never will as I will never 'contract' with you OR the court.

[jamie381]

@tazztt1 How are all tickets illegal? If you break the law expect one. So you win every case before you even leave the scene? and YOU have NO jurisdiction over a police over.. He is NOT REQUIRED to do shit for you unless by law. So you still haven't shown me where a officer HAS to show you his radar information at request at a stop, you just continue to tell me how I'm fucked over by the police when I have no tickets.

[tazztt1]

@jamie381 ... You have alot to learn my friend, hahaha. If you can calm down, I'll teach you some things. If you can't be civil, I'll not respond anymore, and you can pay your tickets (if and when you get them) if you'd like, I'll continue to beat mine. Have a great day!

[jamie381]

@tazztt1 Again, dodging the question. You just keep saying that I'm getting screwed by police. I've got a clean record even though I've gotten several tickets over the years. Keep dodging the question and your no better then the police you keep describing. You say something, then when asked you don't answer, but I want an answer since you say that police must answer the question(radar), so I must be able to have an answer myself. Thanks for continuing to be hypocritical!

[tazztt1]

@jamie381 ... I answered the question. You're having trouble comprehending... "ALL tickets are illegal anyway (except in a case involving an accident) where there is no injured party" no victim no crime, no-one to pay to 'be made whole'.

[jamie381]

@tazztt1 You have just skirted the question of, "Where do you find that officers HAVE to provide radar/laser equipment specs and/or speed at scene of stop". You insist that they HAVE to answer it, but can not provide any evidence of it. I say they don't, and have shown at least something to provide back up to my words. So again, answer the question. "Where do you find that officers HAVE to provide radar/laser equipment specs and/or speed at scene of stop"

[jamie381]

@tazztt1 P.S. I don't need your help to beat a ticket, i'm doing just fine on my own thank you.

[tazztt1]

@jamie381 ... Ok. =)

[jamie381]

@tazztt1 How are all tickets illegal? If you break the law expect one. So you win every case before you even leave the scene? and YOU have NO jurisdiction over a police over.. He is NOT REQUIRED to do shit for you unless by law. So you still haven't shown me where a officer HAS to show you his radar information at request at a stop, you just continue to tell me how I'm fucked over by the police when I have no tickets.

[Pafoofnik1]

@jamie381 said: "it's YOUR responsiblity to prove an officer wrong"

Your area doesn't follow the concept of innocent until proven guilty then?

BTW. You are correct about not having to show speed radar readings, in Texas at least.

[jamie381]

@Pafoofnik1 Again, if you being ticketed for something, it doesn't mean anything other then the officer says you did it. Hell most will even tell you that (if you have to) sign a ticket it's not an admission of guilt, it's just saying you understand what he says you did. Now you have to either fight it and prove innocence or leave it be and get hit with it. So I guess everyone arrested doesn't follow the concept of innocent till proven guilty? Same difference to me.

[Pafoofnik1]

@jamie381: I never said a thing about getting ticketed. I asked if your area doesn't follow the concept of innocent until proven guilty.

[jamie381]

@Pafoofnik1 They do, but it's the officer's job to prove why he's right, making it your job why he's not. Yes, innocent till proven guilty maybe(your obviously not going to just walk around if you were arrested for murder or something). An officer isn't going to defend you unless he's wrong and then he may not because a lot are bad people and don't give a shit.

[erkme73]

@tazztt1 It was a LASER gun (see title), not radar. Laser does not have the same calibration requirements as radar.  All of the defense strategies are based on radar calibration intervals and records, laser simply does not apply.

[FireSarge30]

@erkme73 - Laser has a much farther range than RADAR and as such, he could have clocked you well before this video started....possibly before you slowed a little. Nonetheless, you were speeding. If you used this video and the judge knocked it down...then the system worked in your favor and gave you the benefit of the doubt. At least you didn't get the 15+ cite.

[oipbhakeld]

@erkme73 BOOM! Fucking told his ass.

[StreetMagus]

With all the video editing softwares/capabilities nowadays, how can this be used as valid proof? I'm not saying you're lying OP, but you know what I mean?

[erkme73]

@StreetMagus And on appeal, should the county attempt one, they could have made that argument - and likely would have won. As a defendant, you are entitled to submit any and all evidence for consideration. The magistrate would have been well within his rights to deny the video based on your point, but he didn't. Luck of the draw, I guess. The deck is stacked, as the testimony of an officer is trustworthy and honest UNLESS proven otherwise. Without video, no one can prove anything.

[LaszloPanaflex]

Donut revoked.

[sikofu2]

here's a free tip, just don't speed.



[antney1108]

Well, speeding or not, I am happy that you had that dash cam and proved the cop to be a fucktard! Every ticket he has written for speeding was likely inflated like yours (if not just plain fabricated.) He should have been immediately been moved to a desk job! Thanks for posting this!

[faffaflunkie]

That "dash-cam" can also GET you a ticket. The fact that it shows you going 68 in a 55 zone CAN BE USED AGAINST YOU. Dummy.

[erkme73]

@faffaflunkie

Except the ticket I received was for more than what I was driving - so getting ticketed for my ACTUAL speed is completely acceptable and warranted. If you read the description you'll see that I wasn't out to get away with anything. In fact, I told the deputy, if he wrote me for 68, I would not challenge it. I WAS speeding, just not as fast as the State says I was.

[faffaflunkie]

@erkme73 If that was the case (extreme radar inaccuracy) you got fucked-the deputy should have not been allowed to testify. You effectively testified against yourself, begging for a citation. Next time when dealing with police, keep your mouth shut.

[erkme73]

@faffaflunkie Seriously? I show up in court and just sit there (can't say anything)? When the cop starts to testify, do I bear tackle him to keep him from testifying (since I'm keeping my mouth shut)?

Reality: Guilty until proven otherwise in traffic court.  I have to prove that the deputy is dishonest, or mistaken, (or that his equipment inaccurate). I cannot prove it, unless I have evidence showing the defect. This is called a dilemma. I am happy with the outcome.

[faffaflunkie]

@erkme73 No. You do not have to testify. Before the deputy takes the stand you would use the (your) video to dispute the evidentiary value of the radar. You could even ask to have another judge review the evidence so that the trial judge isn't prejudiced. The Deputy has no business getting up on the witness stand and testifying against somebody when his equipment is inaccurate. Goes to a legal concept called "foundation". You do not have to admit you were in the wrong. They have to prove it.

[erkme73]

@faffaflunkie Now that is useful... thanks. I've never seen that happen in traffic court (magistrates/defense attorneys acting as judges) - but it makes sense. Why wouldn't the hearing officer (or alternate judge) simply not use the video at that point to have the court issue a citation? In other words, if a defendant says, "I couldn't have killed Mike - I was killing Charlie that night", the court wouldn't ignore that 'confession' of Charlie's murder...

[faffaflunkie]

@erkme73 Because we have a concept in the respective state and federal constitutions called "separation of powers". In other words if you were killing Charlie you could not be convicted of killing Mike. Or in the real world a defense that has worked is that "I didn't rob that man-I took his watch AFTER I killed him".

[EatMyDuck84]

@faffaflunkie Stop giving legal advice...you have no idea what separations of powers is.

@erkme73 a better strategy might be to find the cure period in your locale, and request an extension. once the "Cure period" has elapsed the ticket cannot be corrected and must be dismissed in its entirety. Or if you're really ballsy you could show up at arraignment (Do Not enter a plea) and ask the judge "who's the Real Party in Interest?" ----> Rule 17 in civil court procedure.

[stormshockin]

@erkme73 Also, not to mention, since the officer didn't have accurate proof you could have asked for proof/radar test etc etc etc.

Don't mention the speed you were going. If the officer does have some form of proof and you can't get around it, then show the video which would have lowered the fine. If anyone tries to say you were lying you just tell em your were pleading "not guilty" to 72, not speeding. They didn't use the info from your video because they want the other suckers money xP

[devilselbow]

@faffaflunkie Hey cool babby found his first "Never talk to police" video and will now get himself more tickets then he'll save! Good work!

[faffaflunkie]

@devilselbow In the U.S.A. we still have the right not to talk to the police. U.S.A. = #1.

[123qwerty]

this shouldn't work though, doesn't the GPS data always lag behind?

[AlcoholLevel]

wait a second... you're complaining that cop gave you a ticket for doing 72 in a 55 zone... and your video shows you doing 68.

Ya, its bullshit that you were given a ticket but you were clearly ignoring the speed limit. Major speeding vs minor speeding.. pfft. Why should we have any sympathy for you ? I dont. I'm glad you got the ticket.

[MasterDwath]

I would like to see the same video with like 60 seconds prior from where the video the starts. I think maybe the cop got you from way further back, before you probably slowed down.

[envisionelec]

Absolutely fascinating! 

[rockinfaceplant0000]

im guessing you got a ticket you might have wanted to add that into your stupid video before you posted it on the internet where there are millions of stupid people who will never understand what it is that your trying to say

[erkme73]

@rockinfaceplant0000

Not quite clear on the meaning of this post. But sure, whatever he said.

[flguy32501]

@erkme73 I need a dash cam last year. I had my ppc6700 with grainy video 4 years ago and never got anything good. Just Yesterday getting on I-4 from I-275(fly over), a trooper pulls across the end of the ramp to block me. With 200 feet to go, I have to brake hard from 50 to 0. Then he pulls out and leaves me to merge with the pile up behind the 2 semis being escorted by 5 troopers. This was at 4:30PM yesterday!

[flguy32501]

@rockinfaceplant0000 This guy is there for the half way clever crowd. erkme73- KEEP DOING WHAT YOU ARE DOING!!!!

[Streetezz]

@rockinfaceplant0000

Haha, I definitly don't know what you are trying to say. Tard...

[junekentucky]

@rockinfaceplant0000

O_o

The description says he got a ticket so he's not denying the ticket, just the amount the cop was claiming he was driving over the limit.

[rockinfaceplant0000]

@junekentucky gotcha o_o man whata punk ass cop trying to lie just to get his quota and fuck some innocent guy over, fuck the police quick everyone find a cop car and piss on the driver seat !!

[Autostream]

In theory, laser wud b more accurate bcuz its shorter line of sight and satellites must have tolerances? Its just that US military spent a billion dollars so they can kill only BinLAden in a crowded theater whereas the Firm making guns have to make them affordable- its business. I'm sure a billion $ lidar gun would be 0.001mph. BUT hes talking about the COP using the Kentucky Flick where the he flicks it across the car to generate a slightly higher reading when his quotas coming due.

[itsadeadmansparty]

@Autostream too bad for dumb cops,too bad they arent going to get any more money on pointless traffic tickets, Also we could end speeding tickets if we just make cars have a receiver that limits your engine speed, so when you enter a 20mph zone, you can floor the peddle but the engine isnt going a single mph over 20. The solutions exist but we would rather have people die in car accidents, leaving entire families to deal with the trauma,so many solutions actually exist today, but no profit in it

[Autostream]

itsadeadmansparty: YES please. I'd make a fortune disconnecting those!

[itsadeadmansparty]

@Autostream All I want is people to be living safer life, and Police to trust and listen to the average citizen, Usually police dont let you breathe of speak why you were speeding, sometimes we all are late for an important date, some times its a car accident and it isnt even your fault being late, I know the boss would say well leave 40 minute earlier, but then you think? shit should i even go home at all? anyway, we have a lot of technology and its beginning to really help people live better.

[erkme73]

@Autostream

You need to look up the 'slip-effect' on laser targeting.  In theory, you are correct - laser is infinitely more precise than GPS - but it assumes the laser is in a completely fixed/stationary position (i.e. tripod that isn't being touched). The problem comes from the minuscule movement of the muzzle side of the laser as the officer presses the trigger. It causes the beam to sweep the vehicle, introducing huge error in the reading. We'll documented. England banded them forthis.

[Perplexer1]

erkme73, I like that speed imprint in the video. How do you get that done ? I guess I would need a camera and a GPS unit ? Which do you have and how did you connect them together to get that speed in the video ? Thanks.

[erkme73]

@Perplexer1

Look up this model number: GS600, made by a company Dod-tech[dot]com

I've got this one on order which should replace my entire system. And it's only $160 bucks plus shipping from China:

[metalhead9616]

@itsadeadmansparty in main land civilised europe we dont need guns... (execept maybe in some parts of france :D ) and here we are man enough to fight out conflicts man to man and not with pussy wepons therefore making us more honest as well

[metalhead9616]

@itsadeadmansparty but we europeans chose to be governed by reason and not emotions or fear. simply because there is a very remote possibility that i may need a gun it does not mean i need 1. Example: just because the possibility of being struck by a lighning exists , even is very small, im not going to constantly carry a isobaric cage to protect me from it, unless i was to go on a mountain in the middle of a thunder storm, see the connection?

[metalhead9616]

@metalhead9616 its a pharadeischer cage not isobaric lol sry mix up

[XionUnjust]

Thats right dude, fight the power.

[erkme73]

@XionUnjust

I'm trying.

[erkme73]

Right. And if I don't break any traffic laws, I don't need car insurance or my seat belt. Great logic.

[9986mkoh]

It's ridiculous that police (at least where I'm from) don't seem to give a shit about safety anymore. It's all about money money money. A neighbor kid (~14) was pointing a bb gun at another neighbor so somebody in the nieghborhood called the cops and they gave us some bullshit story. And the people were scum that basically ruined a nice, calm neighborhood.

[erkme73]

@9986mkoh

I try not to paint too broad a brush, but obviously, I've had enough first-hand encounters (and heard stories of co-workers and friends) to where I feel it is imperative that every motorist defend themselves with an unbiased witness - both audio and video.

[9986mkoh]

I just got a ticket for 73 in a 55 a few months ago. The cop came up to my window and said I got you doing 63 in a 55 and my friend was in the passenger's seat. Then he came back with a ticket saying 73. I asked him what that was about because he said 63, then he said no, I said 73...I had to work on the court date so i just paid it.

What's ridiculous is that if you fight it in court and lose, they have extra fees. But if you don't, you still pay most of the court costs. What bullshit!

[erkme73]

@9986mkoh

You see, that's the entire point to my efforts, my posts, and my cause. The word of an officer is considered trustworthy and honest unless proven otherwise. The defendant, on the other hand, is guilty unless he can bring something to the table (other than an excuse). Imagine if you had been recording through the entire stop. You'd have had this cop for lunch. And, I'd have put it on the local news.

[jhareng]

The LTI and all other lasers may well have +/-1mph accuracy in a controlled environment, that being lighting conditions and humidity etc.

As you are aware conditions change by the second outdoors and have seen -32/+12% on the same laser in different conditions.

Note silver or white high fronted vehicles will trip it sooner, so buy a matt black car.

[flguy32501]

The new 54 is better than some interstates. I thought is was 60 in that area- should be anyway.

[erkme73]

@flguy32501

No doubt. Just this morning, in the thickest fog I've seen all season, FHP was sitting in the median pining every car hard with KA.

[DEERBAD1]

What if the cops/ judge said you changed the speed in the video with editing software?

[erkme73]

@DEERBAD1

He could have said that and ruled it inadmissible. However, as a defendant, you're allowed to bring all corroborating evidence with you to prove your case. The state must prove their equipment is calibrated/accurate - the burden for the defendant is not as high. Still, I was lucky they let me use it. Totally up to the judge/magistrate/hearing officer.

[BigDH28]

this is a nice win!

[chillpickle420]

You fucken rule! Ya fuck those chicken ticket writing ass fucks! I'm so sick of them in my home town. I get tickets when I'm not even in my car. (front licence plate on my 04 vette) California is fucked cause it's broke and the cops are trying to bail out by writing tickets

[trickers13]

but it just goes to show how those mother fucking pigs r ripping us all off

[trickers13]

thats legit dude ! good for you

[CryptoDriver]

If I had to question the accuracy, I'd question the GPS, it is not designed for pinpoint accuracy on speed measurement.

[erkme73]

@CryptoDriver

LTI 20/20, the manufacturer of the laser gun used in this case, has a published accuracy of +/- 1.0 MPH. The Garmin GPS receiver used in the video has a published accuracy of 0.1 MPH. That 10X more accuracy. It was good for the judge, and good for me. Even the cop came to me after the trial saying "I don't know why my gun was off by that much". FOUR other radar signs all matched my GPS to the MPH. I have no doubt GPS is more accurate.

[CryptoDriver]

@erkme73 I just find it hard to believe that a laser would have that much error, but I guess you would know. Pretty good idea though, although I don't think I could afford it. Pretty neat.

[erkme73]

And questioning law enforcement equipment and its accuracy is exactly what the system does not want us (civilians) to do. Here's a link to the LTI camera used: teletrafficuk[dot]com/pdf/ultr­alyte_100_manual.pdf. - go to page 36. Here's a quote "Speed Accuracy: +- 1mph".

[CryptoDriver]

@erkme73 Don't think I agree with that statement. I have been a cop for over 10 years, but am not a patrol officer anymore, and I can say without a doubt that the system is definitely stacked in favor of the defendant. Regardless, I would not want someone to get gigged for speeding if they actually weren't. I never used laser, I always used radar, which was calibrated yearly and tested daily with tuning forks, with perfect accuracy.

[itsadeadmansparty]

@erkme73 YOU RULE MAN, Thanks For proving that gps is more accurate,

I knew the algorithm in gps must be more accurate, I was taking a long guess but an educated guess, you rule, Good For You, So glad the judge was honest and sided with you, I wish more people knew the truth about Radar detection

[KDC98zj]

i want the same set up 4 off roading / speeding fibs.

[fiishywiishy]

or how bout this, dont speed! then you dont need some overpriced pos cam to record what ur doing

[danecroft21]

i dont get this video.. did he do something wrong?

[mrbobdude101]

@technocat

ya, but isnt it illegal to tape people without their knowing?

[erkme73]

Only if audio is recorded, and then only in the 13 states that have a two-party consent requirement. In my state, the audio recording law does not apply in places where there is no reasonable expectation of privacy (i.e. road side stops). Techno - get a bumper sticker that says "For quality purposes, all traffic stops are recorded". Thus notification is given.

[technocat]

@erkme73

I in fact posted a 1/2" by 4" sticker that has a yellow triangle with a "!" in it, with the following text: "Warning: Video and Audio Recording may be in use." I have one at the top of my driver side window and one at the top center of my windshield.

[itsadeadmansparty]

@erkme73 just a quick question, Isnt your car your property, so if i walk into your front yard, you can record me correct(wo consent)? well if a cop goes into your property(car) you can always record on your own property correct?

until you leave the car are you on public property, Doesnt the law of two-party consent not apply if your in your own property, dude btw you rock, you got the brains i will definitely support you for president, I love honest hard working Fair people like yourself

[THUMPBUMPDUDE]

@erkme73 actually, even if audio is recorded it SHOULDN'T be illegal....as long as its not a wiretap,which is what the laws in some states actually cover, even though law enforcement in those states try to say that includes video cameras with audio.

[itsadeadmansparty]

@THUMPBUMPDUDE your right, isnt your car your own property? and if your friend comes over to your house, you have every right to record on your own property, so doesnt the law protect your right as long as you stand on your own property? I am pretty sure if your at home or sitting in your own car, two party consent law cannot apply, a telephone is in two locations, one at one persons property and the other end is your property being a wiretap, different then just filming a birthday party or home

[comanche119]

nope, it isn't illegal... but it annoys them..

[technocat]

Glad to see you stick it to 'em. I have my dash cam always running just in case something like this happens.

[mrbobdude101]

ur a cop? or you just have a dashcam?

[technocat]

@mrbobdude101

Not law enforcement, just a well-prepared citizen.

[getplaning]

If the LIDAR operator allows the beam to sweep across the side of the vehicle he is tracking, (back to front) the reading can be off by as much as 20MPH. The only accurate LIDAR speed reading is taken with a stationary mounted unit. Handhelds can and are manipulated to give high readings and every cop and prosecutor knows it.

[itsadeadmansparty]

@getplaning i didnt know that about lidar, dude so ur saying handheld lidar can read slightly higher speeds?

[getplaning]

@itsadeadmansparty Yes, it's called "sweep". If you sweep the beam from the rear to the front of the target, the gun will display a much higher speed. BBC did a series on it, it's on Youtube.

[cgripentrog]

Actually GPS is a time and distance measurement. An average speed. We have GPS on our video cameras and it is is always behind your true speed. LIDAR is taret specific and if the operator is using it right dead on.

[erkme73]

CGR... look up the accuracy specifications for LTI 20/20 cameras. Plug it into google. You'll find +/- 1.0 MPH speed accuracy. That's good.

Now check out the Garmin eTrex receiver specs... speed accuracy 0.1 MPH. 10 X better.

GPS and Laser use the same distance over time math. First pop w/laser is distance 1. 2nd pop is distance two.  distance of pop1 - po2, divided by time between pops. No different than GPS - which gets popped 1 x per second by sats. GPS is, hands down, the best.

[erkme73]

I have three gps systems in my car. My radar detector has one with constant displayed speed, my dash camera has it's own display, and my cell phone has it's own.

My speedometer is consistently 1-2 MPH FASTER than all three GPS speeds. All three GPS read EXACTLY the same.

When passing a radar speed sign, it is 100% lined up with my GPS units,not my speedometer.

I I have verified this w/2 rental cars, my wifes car, and others. OEMS intentionally up the speedo. Warranty runs out 1-2% sooner.

[adamackels]

I've owned many police radars, and ALL of them in various vehicles are only accurate to 2 MPH. When a RADAR is certified, it's a 2 section certification, the ground speed for the radar, and the targe speed. Each side is accurate to +/- 1MPH, so that gives you 2MPH. Now on my old '91 Caprice 9C1 police package, the car shows 2MPH off of the RADAR, but never have used a GPS in conjunction. Most cars built with an electric (VSS) are 2MPH off to begin with... Makes you feel good..

[erkme73]

Behind = delayed. Not slower (speed). The speed imprinting on the screen is 1-2 seconds behind real time. Provided I'm driving a constant speed, this becomes irrelevant.

[itsadeadmansparty]

@cgripentrog turns out you were wrong, lol come back to this video, look at the documented accuracy of the LTI-100 laser speed detector is accurate to 1.0+-mph and the Garmin gps is accurate to 0.1mph lol you have been wrong

btw he won the court case with scientific evidence, and good for him

[herrjon]

Look up "sweep effect" - it's real, and it brings in to question the accuracy of speed enforcement readings performed by the most capable lidar guns. There are many youtube videos of "sweep effect" in action. The UK has at least one lawsuit against the laser gun manufacturers do to this problem...

I was a victim of a false speeding ticket due to the "sweep effect" - now I too carry a logging gps unit in my car to provide counter evidence. Fight the good fight... be respectful.

I wish Laser could be beat, but their accuracies are measured to within hundreths. Iin 2007 the US military GPS satellites ,which you were tracking, only have accuracy to within 'meters'. New satellites were launched in 08 that improve that to feet, but when it comes to a comparison it'll be 20 years before GPS is even close. Besides to beat this ticket would be setting a Huge precedent. It would be a $100k trial 4u with dozens of experts to squash the long established credibility of laser. GL

[itsadeadmansparty]

@Autostream lol he beat the court, he proved gps more accurate, you should come back to this video and see, he actually proved laser accuracy to +- 1.0mph and garmin gps to +-0.1mph

[DisposableSoldier]

Don't you think you should show the previous 15-20 seconds of the video for this to be valid?? Where your video starts, the cop's already got you and has put his laser away in preparation to pull you over. I'd bet on a laser over your questionable gps any day.

[erkme73]

DS - the video shown on youtube was compressed (playing at about 3x normal speed to not bore anyone). It's also quite a bit shorter. Based on my speed and time before I passed the cop, the judge agreed that I was more than 1/2 mile from the cop (and around the turn) and all that while my speed never moved by more than 0.4 MPH.

[EBLOVESAR]

looks the same to me

[itsadeadmansparty]

I know your distance and location can be sckewd but you are completely wrong speaking about timing and with use in a car.A intelligent judge would side on GPS over Radar Detection.Radar mechanism is much more higher form of algorithms and speed of the Diode creating the lasers speed and physics. A simple GPS will always be 100 times more accurate then a Laser Speed Detection please do not believe joethec he is trying to stop you from using this in court.Use the GPS In Court!Now Prove Your Point!

[angryadrien]

@itsadeadmansparty Also, from my basic understanding of GPS and radar:

-GPS uses a passive method of gathering info to estimate speed, direction, location.

-radar uses an active method of gathering info, ie. emitting a beam which can be corrputed, rendering the information useless.

[itsadeadmansparty]

actually the gps cant be out of sync, considering its constantly polling the gps encoded atomic time, which is a completely different technology then a radar or laser speedometer. I think the only parts that could go out of sync is the microprocessor; which then if you admit that would mean your computer could be 1ghz one day and 88mhz the next which isnt possible with silicon transistors. The device producing and measuring the laser beam can get out of sync because it uses different methods.

[joethecrab]

Yes the GPS can be "out of sync" and lag and lose signal and all shorts of sheet. I have used GPS intensively throughout my military job all over the planet and now at my civ job. The main point with your speed, is that the GPS speed readout is an average since the last time it read. If you got your ticket tossed, great for you, but I gotta think if the judge had any clue, you would be SOL. If this becomes a prob for the pros I'm sure they will stomp on it.

[itsadeadmansparty]

I still disagree completely - GPS works by sending a copy of the exact time from a certain coordinate of at least three satilites. I feel you already understand that but the clock on the gps is more acturate because it is continuously being updated but this clock is better then your casio timer chip. Since this chip is almost always being updated by at least 1 satilite in the USA it should even run more acturate then a laser or radar speed detector. heres more

[erkme73]

Joe is right. GPS can certainly result in errors - just as easily as any speed detection can. The only difference is that the receiver also provides a variable call Dilution of Horizontal Precision - or DHP. This unit of measurement address all of the things that can cause error, and provides a number / signal strength that can be used in court to prove accuracy. 1.0 is best 10.0 is worst. At the time, my DHP was 1.01 - the entire time.

[erkme73]

My point is, that if you go to court, and you have your facts - including the DOHP - and you can prove that GPS' accuracy is 10x more accurate, and can tell you if there is any error, the guy with the laser or radar gun will sit there looking like a 6yo who just had his candy stolen. There is no counter argument.

[Autostream]

The best compared to what? Does 1.0 means 1% off or 10%? The prosecution will have a field day with that. Besides, its not even calibrated to known standards, you could easily have fed a 4 mph difference in the feed at all times. It was hopeless to begin with. I really admire your cause though and wish you'd win. But GPS is no match for lidar. Only if you'd prove his gun wasnt calibrated, then you'd have this bomb to drop to further prove that point.

[junkymagi]

Didn't watch the end of the video, huh? It shows him going by a stationary speed sign which shows the speed of passing cars, his GPS speed and the sign matched. So, he has more than one example to show the accuracy of the system.

People holding radar guns want to track with the vehicle. That causes errors in the speed shown on the radar gun by the "sweep effect" which is being litigated in several countries.

[Autostream]

junky:This was not the authors defense so its irrelavent to his case and this discussion up to now. But it is a great one. The greater the angle from the cop the slower your speed, Unless the cop can manipulate his Lidar just right alongside your vehicle between the 2signal burst. Of course he's already behind due to his angle, which is why we see only a 6% gain. But my point was that his evidence is poor because I could overlay any 'gps speed' on any video with my Avid in 5 min to fake it.

[itsadeadmansparty]

@Autostream turns out he did prove gps was more accurate then lidar, scientific evidence too, so the court had no counter

[LastReplaySC]

what a shit world.... you have constantly got to prove your innocent... this means your constantly under charge .... ALL Govt's are all out of hand and order! soon you will need 3 witnesses + GPS & camera data to go far a walk legally

[barbequesandwich]

i hope that you guys know that the radar systems in the cars round the speeds down for you benifit... and if the cops radar can be inaccurate...then so can your stupid gps... did you ever think about that???

[erkme73]

BBQ - if your radar or laser is off due to lack of caliration or misuse, would you know it? Would it report out an relative error rate? No. It does not. Thus, any readable result is considered acurate - and incourt, it can't be contested. The GPS collects dozens more data points than just speed. All of these factor in to the DOHP score, which tells the operator how much he can trust the reading. That's a big legal leg up over Laser or Rardar.

[erkme73]

This story may pick national media attention shortly. I am being contacted by local news affillates about my camera system (in my home) regarding another incident - but I think I may show them this video.

[1000000thTUBER]

I went to court an won shoing my GPS readout and time date etc. and won, Pasco uses a crap systems , remember they aren't out there to help , protect, or serve the are there to collect money for county ONLY..

[iamjames2]

awesome dashcam. Quality is really poor though, would be nice if you could read license plates.

[deriley]

What is so inaccurate about it? The dash said 27 MPH and so did the thing in the street.

[erkme73]

The speed on the video is from MY equipment. The laser gun used to give me the ticket was 4 MPH faster than my speed (as shown by MY equipment). Couldn't agree more that my equipment is accurate. I went past 4 other radar speed signs, and my video speed was dead-on accurate with the radar signs.

[rdnkhotshot]

the dash cams cost any where around 1000.00 plus

[sampsonrover]

can you email me the txt showing distance of laser contact, as well as time and date. you can block out other personal info. I'd like to show video and tckt in my own court case. date should show 2/15 (as the video does). Also, where did you get the in-car camera with direction/speed display? Thansk, Dan

[erkme73]

Sampsonrover - sorry I didnt get to you any sooner... I have a full write up here: mp3car [dot]com/vbulletin/1111748-pos­t33 [dot] html

I originally wanted to market the idea, but since I don't know how to start the process, and I want others to benefit from the idea, I posted the parts used... Rdnkhotshot, the whole system is well under $1000...

[erkme73]

Let me just say right up front: Court reduced charges from 72 to 68MPH, and judge withheld points. The point of this video is to show that laser guns can be inaccurate (there's plenty of evidence on-line). Most people do not know how fast they're going when they're stopped... And, unless they have a system like this, it's their word against a cop - and they lose every time.
