The box or bullet camera which supports smart linkage function can locate or track the target according to your demand. Before performing smart linkage during live view, you should configure the smart linkage rules for the box or bullet camera, including linking to a speed dome, calibrating box or bullet camera and speed dome, setting related parameters, etc.

1. Enter Logical View > Cameras to enter the camera management page.
2. Select one area on the area list and click the camera name in the Name column to enter the Edit Camera page.
3. In the Basic Information, click Smart Linkage to open the Smart Linkage settings window.
4. Select a speed dome from the list for linking the camera to the speed dome.
5. Select Manual Calibrating or Auto Calibrating as calibration mode and click Next.
6. Calibrate the camera and the linked speed dome, and then click Next.

   • Manual Calibrating: In Manual Calibrating mode, click Add Calibration Point, and click the position on the left image of box/bullet camera to add a calibration point. Select the calibration point, and then move and zoom in or out the view of speed dome by digital zoom and PTZ control to make sure the live view of speed dome and the target position of the camera are mostly same.

     Figure 1. Manual Calibrating
     Note:

     • You can repeat the operations to add more calibration points. At least 4 calibration points should be added. It is recommended to add at least 9 calibration points in one scene. For higher tracking precision, up to 12 calibration points are required.

     • Click the added calibration point, and you can move it to other position, or delete it.

     • It is recommended to place calibration points at distinct positions in live image (for example, corners). If no distinct position is available, you can place the points at something (for example, box, stool, or people) to mark the position.

   • Auto Calibrating: In Auto Calibrating mode, click Start Calibration to add calibration points automatically.

     Figure 2. Auto Calibrating
     Note:

     You should avoid using auto calibrating for vast similar scenes (for example, lake, lawn, or public square) or dark scenes (for example, night scenes).

7. Set other parameters.

   Auto-Tracking

   If Auto-Tracking is checked, when the VCA event is triggered during live view, the speed dome will track the target automatically.

   Note:

   You need to configure VCA rule for the bullet/box camera on the device. For more details, refer to the user manual of the device.

   Target Tracking Mode

   Track One Target Continuous

   The speed dome tracks the target continuously until the target disappears in the scene.

   Track One Target for Certain Duration

   Select this mode and set the duration of tracking. The speed dome switches to next target after the set duration time.

   Set Tracking Initial Position

   Select a preset as tracking initial position, or adjust the view by PTZ control and click Save to save the preset as tracking initial position. When tracking finishes or timed out, speed dome returns to the tracking initial position. When tracking initial position is not set, the speed dome stays where tracking finishes or timed out.

8. Click Save and Test to finish configuring smart linkage.

   To test the smart linkage settings, click or draw a rectangle on the video of box/bullet camera, and the speed dome will show the close-up view.

9. Optional: After configuring smart linkage, perform the following operations.

   Option	Description
   Edit Smart Linkage Settings	click Edit to reconfigure smart linkage.
   Cancel Smart Linkage	Click Cancel Smart Linkage to delete all configurations about smart linkage.
