DEFINE CCTV KEYBOARDS
The following table shows examples of how to define keyboards. A keyboard must be
defined before it can control the video systems.
Figure 7.8: The 'Define CCTV Keyboards' Tab
7.4.1 Keyboard
(1)
KB(1)
is defined as a general purpose keyboard. It usually has been assigned the
default operator OPR(1). This assigned operator will be automatically signed-on when
the video system starts (cold boot) so the keyboard is ready to use. The keyboard
adopts the access privileges defined against the operator. By signing on different
operator the system access can be completely changed. Signing-off the keyboard, will
disable that keyboard. No system access or control is possible until another operator is
signed back on.
7.4.2
Car Park - KB(2)
KB(2)
is defined to be in a car park attendant's security room. By default this keyboard
is signed-off. It is assumed that the car park security room only has one monitor (being
23) so this keyboard is by default defined to select that monitor. You could choose to
intercept the MON key on the keyboard and cancel it's function preventing this keyboard
from de-selecting monitor (23).
