The B2 range of DVRs can record at up to 5M-N recording giving your customers better than 1080p recording. This range allows both alarm and audio over co-ax to be installed on each channel as well as giving your customers having the ability to control compatible PTZ cameras using the same BNC cable as the video. As an added bonus, each of the DVRs in the B2 range allows for additional IP cameras to be installed and they work with the audio over CAT5e feature allowing your customers to record audio on those cameras too (requires compatible cameras). As well as the extra IP channels the B2 range also accepts video signals in the CVI, TVI, AHD and CVBS formats, giving more flexibility in what cameras can be use on the installation.
