Key factors when choosing CCTV cameras include resolution (2MP minimum, 4MP+ for entrances and payment points), field of view, low-light/infrared performance, adequate storage for your required retention period, and IP-rated housings for harsh environments. The network behind IP cameras — PoE switches and bandwidth — matters just as much as the cameras themselves.
