Note
You can set a maximum of two decimal places.
4.
Click to start calibration.
Caution
●
The auto calibration starts when the person is totally seen in live view, and ends when
the person is in the endpoint.
●
The endpoint-to-camera distance (m) equals 4 times the lens focal length (mm). E.g,
for 7mm lens, the recommended endpoint is 28m (7*4).
●
The person should walk in zigzag path. And two zigzag paths are required. Make sure
the walking route covers the left, middle, right of image.
●
The auto calibration duration should be no shorter than 10 sec, and no longer than 10
min. The device will stop calibration automatically if the duration is too long.
●
If there is moving object such as leave or tree in the scene, you can set the shielded
area . Refer to
Set Temperature Measurement Shield Region
for detail settings.
5.
When the person exits, click to stop calibration.
Note
After auto calibration, refer to
Verify the Calibration Result
to verify if the calibration is
successful. Set manual calibration if the auto calibration failed, or the
veried result
turns bad.
Result
After calibration, the height and angle of camera will be shown in live view.
Calibrate Manually
Steps
1.
Go to Conguration > Perimeter Protection > Camera Calibration or Conguration >
Perimeter Protection > Advanced
Conguration .
Note
The path varies according to different camera models.
2.
Check Manual Calibration.
3.
Click Fig 1. Click
and drag the vertical line until it ts the target.
4.
Enter the actual length of the calibration line.
5.
Repeat steps above to set Fig 2, Fig 3, and Fig 4.
Note
Draw a calibration line in each gure, and the four calibration lines should be evenly
distributed in the same horizontal plane from left to right.
