Preguntas habituales
What does PoE provide to a CCTV camera?
Power over Ethernet carries electrical power and network data on one Ethernet cable, so a camera does not need a separate nearby power outlet.
What is an NVR?
A network video recorder stores and manages video from IP cameras connected through the network.
Why use a separate CCTV VLAN?
A separate VLAN groups camera traffic and can limit which other devices are permitted to access the cameras and recorder.
