Basic functions of the PTZ Camera and explanation of terms

 

  • Cruise functions: The PTZ camera supports preset point configuration, watch position, track cruise, pattern scan, and line scan.
  • Automatic adjustment for the zoom ratio: When the zoom ratio of the PTZ camera is changed, the speed in the horizontal and vertical directions automatically changes with the zoom ratio. If the zoom ratio increases, the moving speed of the PTZ camera automatically slows down. If the zoom ratio decreases, the PTZ camera moves faster automatically. The zoom ratio ensures a better object tracking effect.
  • Power-off memory: If the PTZ camera is performing cruise operation before power-off, after it is powered on again, it continues the cruise operation after the self-test.
  • Link Auto PTZ Tracking: You can used the PTZ camera to track moving humans and vehicles in the detection area.
