Abstract
The method and apparatus includes an uninterruptible power supply along with its rechargeable battery and a plurality of video protection circuits all within a common chassis. The video protection circuits are configured to protect the digital video recorder from surges introduced at the video cameras or cabling. The uninterruptible power supply is configured to provide power to the digital video recorder should a line voltage power failure occur and may also include a surge protector to further protect the digital video recorder from power line surges. Since all components are housed substantially within a common chassis, a method of isolating the video protection circuit and associated connectors from the radio frequency noise within the common chassis is described as well as a method and apparatus to allow removal and replacement of the video protection circuits should a power surge destroy them.
