Most CCTV cameras do not have their own power source or battery backup. They are powered by a DC (direct current) source supplied by a cental power supply (AC/DC) unit. The AC power supply is powered from the mains power supply and will simply cut-out if there is a power outage. By plugging the AC power supply into a suitable uninterruptible power supply, along with any associated security equipment such as an DVR/NVR camera recording system, a CCTV system can be kept running during a power outage, mains power failure or abnormal mains power event.
UPS Battery Backup for CCTV and Secuity Systems
CCTV UPS solutions to provide critical power backup for CCTV cameras and NVR recording systems and protection from power outages to ensure 24/7 operation. Without battery backup the AC PSU power supply unit for your CCTV system will fail and this drives the DC powered cameras and plug-in recording devices. No mains power supply or backup means no active cameras will be monitoring and the site becomes less secure.
CCTV UPS and Camera Backup Power Supplies
Cabled CCTV cameras are powered from CCTV power supply that converts the AC mains power into the level of DC power required. The continuity of security camera’s power supply is therefore dependent upon the present of mains power or battery backup. A wireless CCTV camera’s power supply may be use AC mains power or PoE (Power over Ethernet) but the will still be dependent upon a source of backup protect power to drive the Ethernet switch.

UPS Backup Power Supply Units for CCTV Systems
Many businesses use CCTV cameras as part of their building security systems. The cameras provide 24/7 recording at key entry points to a building and the surrounding areas. The very presence of the cameras can deter unwanted intruders. The camera feeds are automatically recorded on an DVR/NVR and can provide crucial evidence in the event of a security breach.
CCTVS stands for Closed Circuit Television and the cameras are normally powered from an AC/DC power supply. The complete CCTV system should be protected by an uninterruptible power supply (UPS) to ensure continuous operation. The UPS provides protection from power outages, and power problems including brownouts, sags, surges and transient voltages.
Without a UPS system in place, a CCTV system will crash during a mains power failure and the CCTV cameras will stop recording events. The sudden loss of power could also result in damage to the DVR/NVR recording device resulting in lost data and potentially corrupt data files.
