Retail Store CCTV PoE Camera Network

A retail CCTV network diagram shows the path from IP cameras to the PoE switch, recorder, and viewing station. It captures the equipment an installer needs to place: a firewall, core switch, dedicated PoE switch, NVR, and cameras in the areas being covered. Keeping cameras on their own VLAN makes the security traffic visible and separates it from ordinary store devices. Start with the three locations that need coverage, then add the power and data links back to the rack. This drawing is useful for an installation quote, a client handoff, or a troubleshooting visit because it makes the recorder, viewing location, and camera uplink easy to identify.

01Dedicated CCTV PoE switch

Camera power and traffic are grouped together.

02CCTV VLAN

Video devices have a distinct network segment.

常見問題

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.
