Important Compatibility Notes

Motion Detection 2.0 / Perimeter Protection
Motion Detection 2.0 and perimeter protection cannot be enabled at the same time. Enabling one function makes the other unavailable.
Enhanced IP Mode
Enhanced IP Mode may conflict with smart events such as Motion Detection 2.0 and perimeter protection, or with other functions.

Accessories Mentioned

The datasheet does not provide a specific list of included accessories. The following compatible accessory type is specifically mentioned:

  • USB Wi-Fi Dongle: The DVR can connect to a Wi-Fi network through a compatible Wi-Fi dongle connected to its USB interface.

Hard drives are supported but no HDD is identified as an included accessory. The recorder provides two SATA interfaces and supports up to 10TB per HDD.

Ideal Applications & Common Uses

  • Existing analog CCTV upgrades: Ideal when upgrading an existing coaxial camera system while retaining compatible cabling and analog cameras.
  • Hybrid analog and IP surveillance systems: Useful for installations that need to combine HDTVI, AHD, HDCVI, CVBS and IP cameras on a single recorder.
  • Large residential properties: Suitable for homes requiring multiple camera locations, human/vehicle filtering and remote viewing.
  • Retail stores and offices: The 16 analog channels, smart search and human/vehicle classification make the recorder suitable for monitoring entrances, parking areas and interior spaces.
  • Warehouses and commercial properties: Perimeter protection can be used for line-crossing and intrusion detection around controlled areas.
  • Parking lots and exterior monitoring: Human and vehicle classification can help operators identify relevant movement while reducing alerts caused by non-target objects.
  • Expandable surveillance installations: IP camera support allows an existing analog installation to be expanded with higher-resolution network cameras as requirements change.
  • Central monitoring environments: 16-channel synchronous playback, smart search, Gigabit Ethernet and up to 128 remote connections support larger monitoring applications.
