There's been a spate of robberies in our area recently, and I'm looking to install a couple of cameras. Our requirement is pretty basic. 2-3 cameras maximum. 720p resolution minimum Outdoor, bullet type cameras. Decent IR range (~15m) Budget ~$400 What we have: Wiring. The house was pre-wired for three analogue CCTV to a central DVR location. These are effectively a COAX cable and DC pair for each channel. NAS. I've got an old synology nas running surveillance station app. Not sure if it has enough grunt. Don't really want to pay for additional camera licenses. Server. I've got an old PC that are running 24/7 acting as a glorified squeezebox server. It's a SFF, will need an external DVR card to repurpose. Given the tiny budget, I would prefer to leverage what we have already as much as I can. I heard Hikvision and Foscam cameras are good value but I don't want to re-wire to IP. Budget also rules out Ethernet/POE over coax converter which are quite expensive. I'm thinking that this rules out IP Cameras altogether? Suggestions?
