Advanced Features

The advanced features of pan-tilt-zoom (PTZ) control include patrol and tracking.

• Patrol: The camera moves in a specific pattern during the specified time period.
• Tracking: When an object triggers the motion detection rule, the camera will use the PTZ feature to lock the moving target in the center of the screen.

Patrol

The patrol feature is divided into two categories:

• Simple patrol: The user creates a patrol schedule on the mobile app. When the scheduled time is reached, the mobile app sends a DP command to the camera. The camera will perform a full rotation, staying at six points for a specified time period, and then return to its original position. The duration to stay at each point can be set on the mobile app and sent to the camera through E_TY_MSG_PTZ_PATROL_STAY_TIME.

• Non-simple patrol:

  By patrol mode:

  • Panoramic patrol: The camera continuously rotates to six evenly spaced horizontal points sequentially. Cameras with infinite position structures repeat rotation to the six points with this pattern: 1 2 3 4 5 6 1 2 … while cameras with limit position structures follow this pattern: 1 2 3 4 5 6 5 4 …
  • Site patrol: The camera patrols continuously between the user’s site favorites.

• Non-simple patrol

  By patrol time:

  • All-day patrol: The camera patrols continuously until the user disables it.
  • Timed patrol: The camera only patrols during the specified time period.

Tracking

The external program enables or disables tracking through E_TY_MSG_PTZ_TRACK. Currently, vertical tracking and horizontal tracking are supported. You can set MOTOR_TILT_TRACK_SUPPORT to enable vertical tracking. The pan-tilt (PT) camera and the PTZ camera typically only support horizontal tracking.

The following diagram shows the tracking process.
