Two modes are available. Controlled by target frame or by lt angle of the device.
By Tilt Angle
The device calculates the tracking zoom rao automacally according to the lt angle of
the device.
Note
The atude of the device aects the accuracy of this zooming control mode. For the
model with a built-in gyroscope, try to calibrate the aîž«tude if some zooming problems
happen during tracking. See Set Device Posion for instrucons.
By Target Frame
The tracked target has a virtual frame around. The device calculates a suitable zoom rao
according to the frame and the set Tracking Zoom Rao. Larger value means bigger zoom
rao.
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 waing me level before the device stops tracking
when the validity is low. Larger value means longer
waing me.
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 waing me level before the device lowers
the tracking speed when the validity is low. Larger value means longer
waing me.
