We have got our Video Server up and running. After many hours of research, planning, and allot of work on programing, our proof of concept is done. While almost all our cameras are NTSC CCTV cams and limited to 640x 480 interlaced image, the sever is completely capable of much much higher resolutions even exceeding the ATSC HiDef standard.
We are breaking new ground as nothing like this has been attempted by any other group. I have been working with a camera manufacturer for the last four months now on a all digital camera that we can exchange the sensor on and support at the moment up to 3MP at a full 30 frames per second.
The core circuit design is completed and the camera has one core processor supported by two RISC processors to make sure the camera is always up to the job. It's just a bit of programing left there as well to have the cam send the video in the proper format to our server and we should have that done in a few weeks. I still have to completely work out the audio to work the way I want but I have proved that I can get synchronized audio with the video format that supports Wav with very little compression and hopefully be completely customizable and a lossless as realistically possible. Lossless audio with wide spectrum coverage eats up a lot of storage space and so does our video.
In terms of high quality though, it comes at a price. Storage can cost as much as 32GB an hour per cam to 324GB an hour at 3MP per and more. At NTSC standard image size of 640x480 interlaced it's 16GB an hour not including audio. There is no way to review the video without a computer at the captured resolution without converting/exporting it to a supported format. Archival of this information is extreamly expencive obviously, so unfortunatly we will need to just make clips of anything interesting at full resolution, and export the video in it entirety to ATSC to go on a DVD for the archive and to present to our clients. Otherwise we would likely requrie more storage space than Microsoft and Google combined in a very short time. |
