Hi everyone,
I’m looking for some advice and suggestions on building a portable cctv system to support a research project that I am conducting. The project is concerned with image processing of cctv video images in indoor environments. I don’t know an awful lot about the hardware side of systems, so I am hoping someone will be able to point me in the right direction.
I want a build a portable system supporting 2 colour cameras (probably low-light capable) which can record video images at the highest possible resolution. I’ve seen cameras advertised which can capture at 752x582. This is ok, but I am wondering if it is possible to capture at high resolutions? Frame rate is not so important: 5 - 10 frames per second would be ok.
The captured video ultimately needs to be transferred to PC, so I am thinking of using a DVR capture card to record straight onto a PC. I haven’t seen any cards advertised that support 752x582 though. Does anyone know of any? I also want maximum flexibility in terms of compression encoding, as final image quality is important.
I notice that DVR cards often have automatic recording control based on motion detection. I would also like to be able to configure this and have the option of using it or not.
Finally, I would like to be able to record for as long as possible without changing media – which is why I am thinking of using PC + DVR Card + Big Hard disk.
If anyone has any suggestions, advice or comments I would be very grateful.
