The Guardian Series equipment can be configured for add
drop and pass networks. Because of the digital transmission
technology the transmitted signal can be repeated effectively
indefinitely without any loss of signal quality. Thus for
cameras distributed over large distances the Guardian Series
equipment is ideal for collecting them and bringing them
back to one or more control rooms.
Any
number of Guardian units can be connected in a 'Daisy
Chain' manner.
Camera signals are
collected from each node and tranmsitted onward to
the control room. Upto 20 camera channels can be transmitted
easily on each fibre using the two wavelengths of
1310nm and 1550nm.It is possible to transmit up to
320 channels using DWDM technology.
The camera signals
can be 'dropped off' at any location.
Each Guardian unit
has within it a full cross-point switch. Using this
facility allows any number of cameras to be connected
to the network. Only the signals selected will be
transmitted. The selection can be done using either
AMG's MUXcom software or using a third party control
system. This removes the need for any large matrix
switch at the control room.
The switching facility
also allows selection of which camera signals are
'dropped off' and where.
