4.2.1. Pan/Tilt

Pan/Tilt is a function used to move a camera up and down or left and right. However unlike the mechanical Pan /Tilt

which is carried out by physically moving the camera up and down, this functions by using smaller video mode than

the CCD’s effective pixel and moving the image up and down. This results of a cut off pixel from the whole image

which user can specify by the Pan/Tilt command. Pan/Tilt range and values depend on the characteristic of each

CCD used in the camera respectively as per the following tables. Note that at Format 7 mode, the pan/tilt value

must be set at non-format 7 mode before operation.
