How to choose a Dahua DVR

When choosing a DVR, you need to study its characteristics:

  • signal processing technology. Dahua Network Video Recorders (NVR) are compatible only with digital cameras, digital (DVR) - with analog, and hybrid (XVR) support both types, capable of digitizing analog signal of CVBS, AHD, HD-TVI, HD-CVI standards;
  • the number of analog or digital cameras that can be connected;
  • recording resolution, which should match the resolution of video cameras and video surveillance purposes;
  • number and size of hard drives. In addition to the number of channels and permissions, which directly affect the size of the archive, you must also take into account the desired storage time. The most advanced models of Dahua DVRs support the technology of combining HDD into a RAID array;
  • the downstream rate on which real-time recording depends. The total stream must be divided by the number of channels;
  • power parameters (operating voltage), PoE support (the ability to supply power and signal through one cable);
  • video compression format (currently the most progressive algorithm - H.265 +);
  • availability of PoE ports for connecting digital cameras directly, without a router.

Other interfaces are also noteworthy - the presence of audio inputs and outputs for connecting a microphone and speakers, alarm inputs / outputs for integrating security system elements, BNC video inputs for a coaxial cable, the number of VGA, HDMI ports for connecting a monitor (computer or high resolution). You should also pay attention to the capabilities of video detection, remote access, data backup, recording scenarios and other functional features.
