  - Add a video analytic license to a camera
    To use a video analytic on a camera, you must add a license that includes the video analytic to the camera.
  - Draw a processing mask
    You can draw a processing mask for a video analytic in the Senstar Symphony Server configuration interface to define the area in the camera view that the video analytic analyzes.
  - Calibrate a camera
    For some video analytics, you must calibrate the camera to achieve optimum performance and accuracy.
  - TCP Listener
    The TCP Listener is a video analytic that listens for incoming metadata over a TCP socket and associates the metadata with an image or video.
  - Analog Video Signal Loss
    The Analog Video Signal Loss video analytic is a video analytic that can detect when video from a camera is unavailable.
