HD video surveillance is built on the shoulders of HDTV and video compression.
This new world of high definition gives us 10 times the resolution of our old TV's along with studio quality sound in a package that is thinner, cooler and cheaper.
This is a very happy story. But the real story is how H.264 allowed this dream to become a reality.
HDTV was first developed by the Russian Military in 1958 and ten years later put into use by the Japanese. Practically speaking, this technology 'sat on the shelf' for the next 30 years because no one could figure out how to transmit the massive amounts of data required to feed its appetite.
Enter H.264
In the early 90's NASA's Jet Propulsion Laboratory needed a way to teach cruise missiles how to find their targets. They developed the science of 'pattern-recognition' which taught the missile how to recognize its target through a cloud of pixels.
Now that they could distinguish a unique object inside a larger image the next step was to compress this object into a token. If the object didn't move in the next frame, the camera simply re-wrote the same token thus reducing transmission volumes up to 10,000 times.
Our previous videos have shown that large homes can require many cameras that could generate massive volumes of data. Instead, we place our camera artillery onto this compression fortress to defend our property.
