Standard Device Control
Other video equipment that requires only simple relay contact control of one or two
functions (e.g.. freeze frame units, single channel motion detectors) can be configured
into the system as a Standard Device. The video system will use a relay output module
to distribute control to this type of equipment.
2.14.4
Smart Device Control
Video multiplexers, video printers and other smart video equipment have remote control
ports. RS-232 data communications and Infrared remote control is possible using a
Peripheral Control Interface module. The operation of this equipment is enhanced and
simplified for easy use.
Most video equipment can be integrated into the MAXPRO-Net crosspoint matrix video
switcher system.

CAMERA FAILED DETECTION
The MAXPRO-Net system supports camera failed detection when the camera fail
detection modules are installed. The camera fail detection module (RD-89) would have
to be installed into every primary video switching subrack used in the video system.
Three types of video fail are checked for every camera being monitored, even while the
cameras are not displayed on a monitor.
2.15.1
Lost video
If a camera fails or its video cable is broken (i.e. a complete loss of video sync), then a
'LOST VIDEO' alarm is generated identifying that camera.
2.15.2
Low level video
Even if the camera's video signal is NOT lost, the camera scene is electronically
monitored. If the video picture should go completely black for several seconds, then a
'LOW LEVEL VIDEO' alarm is generated identifying that camera.
This alarm could be caused by area lighting being turned OFF, the camera lens being
covered, or the lens iris being completely closed.
2.15.3
High level video
If the video picture should go completely white for several seconds, then the alarm
'HIGH LEVEL VIDEO' is generated identifying that camera. This condition could be
caused by the iris opening being jammed or a faulty camera.
