Note
The attitude of the device affects the accuracy of this zooming control mode. For the
model with a built-in gyroscope, try to calibrate the attitude if some zooming problems
happen during tracking. See for instructions.
By Target Frame
The tracked target has a virtual frame around. The device calculates a suitable zoom ratio
according to the frame and the set Tracking Zoom Ratio. Larger value means bigger zoom
ratio.
Wait to Stop Tracking If Low Validity
The validity is an internal parameter that helps judge whether the device should keep
tracking or not. This parameter is the waiting time level before the device stops tracking
when the validity is low. Larger value means longer waiting time.
Wait to Lower Tracking Speed If Low Validity
The validity is an internal parameter that helps judge whether the PTZ channel should lower
the tracking speed or not. This parameter is the waiting time level before the device lowers
the tracking speed when the validity is low. Larger value means longer waiting time.
5. Optional: Check Tuning Mode.
Note
Tuning mode is to display the information that helps debugging the function. This mode is
reserved for technical support.
