Wired security cameras transmit video and audio signals through a wire to a central hub. The footage can either remain local on the hub for later viewing or it can be sent outside of the home to a network. The network allows users to view the video live or watch it later.

Wired security cameras receive their electrical power via a hardwired cable. This power might come directly from a power outlet. Or the power may be sent through the wire that connects to the central hub: the PoE (Power Over Ethernet) cable.

The central hub is usually located in or around the home. The hub is sometimes a digital video recorder (DVR) that is attached to the cameras with coaxial cables.

Alternatively, the hub may be a networked video recorder (NVR) system, which is used with the newer Internet Protocol (IP) cameras. Instead of coaxial cables, the NVR system uses PoE cables.

Pros

Clear video and audio signals

Reliable signals, should not drop

Constant power to cameras

24/7 Recording - All footage of each event

Cons

Not portable; system remains with the house if you move

Lengthy wiring must be hidden

Wiring must be run to numerous locations

Advantages of Wired Security Cameras

With the prevalence of low-cost Wifi security cameras, it’s easy to perceive wired camera systems as a thing of the past. This is far from true. Wired camera systems are a strong option for home and business security and they offer advantages over wifi systems.

The chief advantage of wired camera systems is that the feed to the hub remains safe. The signal will not break or degrade. As long as the wire is in place, the hub should always be receiving the feed uninterrupted and at maximum fidelity.

Wired security camera systems work well for multiple camera installations throughout many rooms of the house and to the exterior because the signal will not be impeded by walls.

Disadvantages of Wired Security Cameras

Installation is the main downside to wired security camera systems.
