Video output modules. These provide protection and signal conditioning for up to
16 video outputs. The units are available in 8 channel and 16 channel versions,
each of which may optionally include independent video titling on each output.
The entire system is based on a modular approach allowing for flexibility in configuring
video control systems to suit a wide variety of applications.
SYSTEM OVERVIEW
The configuration of a video surveillance / monitoring control system is highly dependent
on the operational requirements of the system. The modular building block approach
allows for different system configurations to be readily set up to suit differing application
requirements.
Each system must contain at least one VideoBloX chassis. It is possible to connect more
than one chassis either at the same location or at different locations with suitable data
and video interlinks between the various racks. The form of interlink depends on the
system type. It could be hard wired, fiber optics, radio, microwave or other. If there are a
large number of video sources at a location which is remote from the monitoring location,
then it is generally more cost effective to distribute the matrix switching system by
locating a sub-chassis at the remote site (/s). This principle can be repeated for any
number of remote sites.
Regardless of the number of sub-chassis required for a system, there will generally be
one master chassis. The master chassis must contain a CPU module.
Generally, all VideoBloX modules have their own power supply units on board. All signal
lines that run to the field are protected against limited over-voltages. Where any
processing is required, this is done to the greatest possible extent in a distributed manner,
with each module taking care of its own housekeeping. Local supply voltages are
monitored and the module will be reset if the supply falls below the threshold. Watchdog
timers monitor the operation of local CPU circuits and reset the circuits if a malfunction is
detected. Each module has a DIP switch which is used to set the module address and
indications which show the critical system status (power and communications). A broad
range of diagnostics for each module is also provided.
RACK MOUNT SYSTEM CHASSIS
VideoBloX is housed in an 19" standard rack-mount industrial chassis. Various chassis
heights are available to allow for different sized systems. The number of modules, which
may be fitted, is shown in the following table:
