JVC VN-C3U - V-networks Pan/tilt/zoom Camera Instruction Manual page 26

On-screen Pan/Tilt Function
Without using Pan/Tilt operation buttons, Pan/Tilt is manageable by double-
clicking on screen. The double-clicking point becomes around the center
or screen.
Caution
During the Pan/Tilt operation, the images may pause for a few seconds.
This is because the position correction function is automatically being
operated and this is not a malfunction.
Caution
It is not possible to move
beyond the Pan/Tilt limits but
this is not a malfunction.
