Cable
A 4-wire sytem cable (see specifications) is supplied as standard.
For optimum picture quality a standard dual ‘twisted-pair’ (telephone)
cable should be used (fig. C).
The maximum distance that can be bridged (without a cable extension
adapter) between the monitor and the cameras is 300 meters (200 meters
for colour cameras).
Caution:
The plugs used for the observation system have the same
dimensions as standard telephone plugs. Never connect a telephone to
the camera or system monitor.

free cloth or a chamois leather cloth.
