cctv42.co.uk - using cat5 cable and baluns to connect a cctv camera to your DVR

[dalitiko]

Hi. Thank you for this excellent video. Do the baluns have polarity? If they have, how to connect? from one balun's Positive to possitive on the other balun, or positive to negative? (invert)

[cctv42]

@dalitiko The baluns do have polarity, yes. This is indicated by a small '-' and '+' sign on the balun itself so you can see which is which. You do not invert the polarity and you do connect '-' to '-' and '+' to '+'. If you need any further information, just give the office a call on 01895 233311. Cheers. Matt

How do you remove the jacket from the 8 internal coloured 0.5mm wires without cutting the copper wire? Ive struggled many times to find a cable stripper for 0.5mm cable but they seem to be non existent. Thanks

[flamesecure]

thanks for the vid, how mutch quality loss is there when using baluns?

[cctv42]

@flamesecure None at all. The baluns are a very good way of transmitting the images. The construct of the cable ensures that there is minimal interference introduced into the image.

Henry thanks for ur response on how to weatherproof all the connections , i saw in ur vid that u are using 3 pairs of utp cable for voltage how far can i extend using your 3-pair tip , and have u been thinking on selling on ebay??

Thanks!

[cctv42]

@ipsademexicotv You can run power and video over CAT5e for around 60 - 70 metres...but the exact length is dependent on the camera at the end of the cable. If you need any further help on this then just send us an e-mail. With regards to eBay, currently we have decided against selling on eBay because unfortunately there are a lot of questionable products and suppliers on eBay, we wouldn't want to be tarred with the same brush as we like to offer high quality products and great service.

Your video is excellent ,1 question How do you recomend installing on the outside ?? should i just use a 3M Electric Tape all around the balun and ac plug???? Thanks in advance Robert

[cctv42]

@ipsademexicotv thank you for your comments. When installing cameras outside, we always recommend keeping the connections dry. For this purpose you would be best advised to use a weatherproof enclosure of some sort. We stock one which can be seen on our website at: cctv42.co.uk/content/94/weathe­rproof-box-for-outside-cable-c­onnections.aspx

you're welcome - glad to be of some help! Matt - CCTV42.co.uk

gracias por el video, es muy demostrativo :)

[cctv42]

Yes, correct a single cat5 cable can handle up to 4 individual video feeds if the cameras are powered locally and we use this feature a lot with multi-camera cctv systems. Just plain old Cat5 cable. What I would say though is use pure copper rather than CCA (copper clad aluminium) because it works better and has less of a tenancy to break due to metal fatigue at the balun joints. Henry

[formidable38]

Il be dammed, that stuff is just like common garden networking cable or even phone RJ45 cable. I was under the impression it had to be screened for noise suppresion and complex like a sat cable or something. Thats nice and simple, Thanks, very imformative.

[cctv42]

@formidable38 it is just standard 'networking cable' or UTP cable. If you're looking at using this type of cable for CCTV, ensure the cable is 'Pure Copper', not 'CCA' or 'Copper Clad Aluminium' (also known as 'Copper Coated Aluminium') as it is a better type of cable with better electrical properties.

Great video. Today I was talking to a friend of how to install the dvr usb using cat 5 cables and i just found this.

As i saw, you are only using + and - cable for the video. so one cable can hold 4 cameras if you power the cameras locally.

[cctv42]

When you use the Cat5 UTP cable to run signal from 4 cameras as in our example on the video you will have to power each camera locally because there is no remaining capacity, all the pairs have been used for video signal. Each pair of wires can only do video or Power, not both at the same time. Hope that answers you question and sorry it took up 2 posts! Henry - CCTV42.co.uk.

[cctv42]

I'm afraid I don't speak Spanish but it looks like you have a question about powering cameras over the Cat5 UTP cable. Depending on the power requirements of the camera and the length of cable run it is possible to power the cameras over the UTP cable. We recommend combining the 3 remaining pairs of wire together for the power feed to reduce voltage drop. For more power hungry cameras or longer runs power the camera locally and use the UTP for video only. More details on cctv42.co.uk

@cctv42

Hi Sir.. Excelent video. Can I use 1 pair for video, 1 pair for audio and 2 pair for power feed? What could be the maximun distance for this configuration??

Thx.

(sorry for my bad english)

[cctv42]

@coldlogik You can do that, yes. The reason we combine the remaining 3 pairs is to reduce voltage drop down the wire to the camera. We have found that with 3 pairs for power, up to 60 or 70 metres should work fine (unless you have a camera with a high power consumption). I would guess at around 40 metres with your suggested configuration. Remember when installing to test with the IR on as well as off as this draws more power. Matt - CCTV42.co.uk

es solo de utp Por camara? Donde conecto En Un utp 4 balun SE NECESITA Otro utp párr Alimentar la camaras? me gusto su video pero ya ultimo no le entendi.
