How are CCTV systems commonly powered?

CCTV systems are commonly powered using conventional electrical sources or Power over Ethernet (PoE). This method allows both power and data to be transmitted over the same Ethernet cable, making installation more straightforward by reducing the number of cables required. PoE is particularly advantageous in situations where running separate power lines would be difficult or expensive.

In addition to PoE, CCTV systems can also be connected to standard electrical outlets, providing an additional layer of flexibility in terms of installation locations. Using conventional sources ensures a reliable power supply, which is critical for the ongoing operation of surveillance cameras, particularly in security applications.

While solar panels and backup batteries can be used in specific circumstances, such as in remote locations where conventional power sources are unavailable, they are not common in standard setups. Wireless charging is not a widely adopted method for powering CCTV systems, as current technology typically does not support reliable data transmission and power delivery through wireless means at the effective range needed for surveillance applications.
