Network Cameras

It can then transmit both audio and video to a recorder such as NVR or XVR for storage and remote viewing via monitor or smartphone apps. The main advantage of the network camera is it can use power over the same ethernet cable (Cat5e and Cat6) which is also known as PoE. It means you don’t need to find a power source nearby to install every single camera like analog cameras.
