The difference between DVR and NVR security systems come down to the cost, how the data is transmitted, and type of cameras involved. NVR systems tend to have better picture quality, as well as easier installation, increased flexibility, and native support for audio on every camera that has a microphone.
What’s better BNC or PoE?
If your network switch can provide POE and your cable run is under 90m, then POE is better by far. BNC could get you more range but you’ll need to have power available the camera location. With POE there are fewer components for fail (just one cable, not two).
Are IP and PoE cameras the same?
PoE technology is used to transmit both data as well as power through a single cable. IP cameras equipped with PoE technology can send video records to the network while receiving power from the same PoE switch. This makes the installation process more flexible and easier than the latter.
