The NVR also supports an optional Point of Sale (POS) feature, ideal for grocery and retail stores, for monitoring cash transactions.

  • Camera loses or changes focus drastically
  • Error writing to an onboard microSD card
  • Error sending or receiving data over the network
  • Unauthorized access to the camera
  • Motion: An object moves through any part of the scene
  • Tripwire: A target crosses a user-defined line
  • Intrusion: A target enters or exits a defined perimeter
  • Scene Change: A person/object moves the camera to change the scene or covers the camera to obscure the scene
  • Abandoned/Missing Object: A target leaves an object in a designated area, or removes an object from the same area
  • Facial Detection: Detects and captures a snapshot of a human face in a defined area within a scene
  • People Counting: Measures the number of customers, visitors, or passengers in a surveillance scene
