Camera Switcher Pulse Submenu
The Camera Switcher Pulse Menu allows the control of an external video camera
switcher. The recorder generates a command pulse used by the switcher to trigger the
selection of its next video input. In other words, it causes the switcher to ‘switch’ from
camera to camera (usually several cameras are connected to the switcher) for recording
purposes, at a rate determined by the recorder. Separate rates may be programmed for
normal recording and alarm recording. The polarity of the pulses from the recorder may
also be programmed.
Both Normal and Alarm recording allow you to program rates of 1 to 99 fields per
camera. Also note that although this menu allows you to record the number of fields
recorded by a camera during an alarm, the entire duration of the alarm recording is
determined by the Duration line of the Alarm Record Menu. In other words, the
Duration line of the Alarm Record Menu determines the total time that the unit will
record during an alarm.
Active edge may be set to either positive or negative. This parameter should be set to
Neg
if the video camera switcher switches on a negative going edge or
Pos
if it switches
on a positive going edge.
Note
If you are not sure of your camera switcher’s active edge (timing wave), the
result of this setting is easily seen on the monitor. The picture will appear to
be ‘torn’ or jumbled. If this occurs, try changing the Active Edge parameter.
Note If set to 00, no
pulse will be produced
and switching will be
disabled.
