INTERCEPT KEYBOARD KEYS, CONTINUED
7.5.2
Unlock [pan-left]
In the second definition the pan left action of the joystick (on all keyboards) has been
intercepted. The key replacement macro is defined to first execute SYSTEM MACRO
(20). Assume that system macro (20) would be written to UNLOCK the PTZ control for
the currently selected camera. Then the key replacement macro performs a normal
pan-left PTZ function.
When the joystick (pan-left) is released, the KEY-RELEASE-MACRO is executed. The
pan-halt function is performed followed by the execution of SYSTEM MACRO (21),
which is assumed to LOCK the PTZ control of the currently selected camera.

Auto-Record
The third definition intercepts the
replacement macro uses extended macro mode to copy the currently selected camera
to VCR(1), select the video output of VCR(1) onto the current monitor, and place VCR(1)
into RECORD. The operator now can control the VCR by simply pressing the
appropriate control keys on the keyboard (stop, play, rewind, etc.).
7.5.4
View Perimeter
The fourth definition intercepts the
key replacement macro executes USER MACRO (01). It would be assumed that user
macro (01) has been programmed to select a suitable camera onto the monitor and
operate the PTZ controls of that camera to WALK it along the perimeter fence.
