NVR Accessories

No separate NVR accessories are listed in the provided NVR datasheet. The recorder supports compatible SATA hard drives with capacities up to 10 TB per disk and an optional eSATA interface.

Ideal Applications and Common Uses

  • High-resolution surveillance systems requiring 16 or 32 IP camera channels.
  • Retail stores that need POS information displayed over live and recorded video.
  • Warehouses and commercial buildings requiring centralized multi-camera recording.
  • Offices, entrances, parking areas, and property perimeters requiring human and vehicle classification.
  • Locations that need full-color monitoring in low-light and nighttime conditions.
  • Projects requiring local camera storage, NVR recording, or automatic network replenishment.
  • Installations using compatible VCA, ANPR, heat-map, or people-counting cameras.
  • Outdoor locations requiring an IP67-rated camera where specialized anti-corrosion protection is not required.
  • Systems requiring local 4K monitoring and up to 16-channel synchronized playback.

Environmental note: The DS-2CD2387G2-L(U) has no specific anti-corrosion protection. The datasheet does not classify it for locations requiring professional or moderate anti-corrosion protection, such as coastlines, docks, chemical plants, or areas affected by acid rain.
