A hybrid security DVR (Digital Video Recorder) is designed specifically for those situations where you need to deploy both analog and IP based Closed Circuit Television (CCTV) surveillance cameras. This situation often arises when a security DVR (Digital Video Recorder) upgrade is necessary. Typically there are existing analog Closed Circuit Television (CCTV) security cameras installed but the need or desire to add IP based surveillance cameras to the system exits. While this is not complicated, selecting the proper equipment is critical for the surveillance system to work as expected.
