I'm looking into adding a video replay system to our pool for springboard diving training as the visual feedback is extremely useful. I plan to send the video signal to an LCD panel with a built in DVR which can do time shifting so we can run the playback on about a 10-15 second delay so the divers have time to get out of the pool to see how their previous dive looked. I've found a few LCD TVs with built in DVR capability and now I'm looking for either a 1080p or 720p camera which can feed a signal over either HDMI or DVI to the LCD panel. There seem to be a lot of cctv cameras out there but I haven't found any that do 1080p or 720p over HDMI. Can anyone suggest places I can look for such cameras or let me know if they even exist?

Thanks for the reply Soundy. After doing some more looking around it seems that the LCD with built in DVR I thought I would use is an older model and I can't find them anymore and I'm not finding any others. I may have to rethink this. I was hoping to find something with as few parts as possible since installation is going to be difficult but I plan on mounting the panel across a corner so there will be some space behind it to house a small DVR or PC to handle time shifting the video signal. Would using a PC or stand alone DVR open up more options for me as far as cameras go? Another thing that would be nice is to have a camera that doesn't require a separate power feed. Sre there cameras that get power over the same line as the video signal?
