The lens
CAUTION:
Do not touch the glass of the lens. This could damage the
delicate coating on its surface. If the lens has to be
cleaned, use a special lens cleaning tissue, available at
any good camera store.
Focus range
The built-in lens provides an optimal image sharpness for objects
between 1 metre and infinity (depth of field).
Cable
A 4-wire system cable (see specifications) is supplied standardly.
For an optimum picture and sound quality a standard dual 'twisted-
pair' cable should be used.
There is an extensive range of plugs and tools available in the hobby
and professional trade to extend the cable. Always pay attention that
the connection corresponds to figure B.
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.
The maximum distance that can be bridged (without a cable
extension adapter) between the monitor and the cameras is 300
meters.
