Protective cover
For outdoor use a protective cover (fig. A-10) (optional) has to be used to
protect the camera from rain and snow.
System connection
Connect the system cable to the output of the camera (fig. A-12).
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'
(telephone) 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.
