The Pro Series 4-Channel Penta-brid 1080p Mini DVR with 4TB HDD from Dahua Technology lets you upgrade existing video surveillance systems while leveraging existing networks, cabling, and cameras. This XVR utilizes Penta-brid access technology to seamlessly record video from HDCVI, AHD, TVI, CVBS, and IP sources simultaneously. The XVR offers advanced options such as built-in motion detection algorithms, alarm triggers, and customized recording modes. XVR technology is a suitable solution for actively monitoring and recording video feeds in a wide range of environments including public venues, retail stores, transportation hubs and access ways, personal property and homes, and educational institutions.
The Smart H.264+ video compression standard can reduce bit rate and storage requirements by up to 70% without having to invest in new cameras. The XVR automatically recognizes the incoming signals of each attached camera without any setup. The XVR supports 5MP resolution (2560 x 1920) on IP camera inputs for recording and live viewing. The XVR offers a variety of configurable scheduling options that save HDD space and active monitoring time. Smart Search allows an operator to specify a region in the playback video to search for a motion detection event, saving time and manpower.
