3 Applications
The infrared floodlight has especially been designed for video
monitoring systems. It switches on automatically if the am-
bient brightness drops below 10 lux and switches off if the
brightness increases correspondingly. It can be used indoors
and in a restricted way outdoors (safety class IP 33 = rain-pro-
tected up to an angle of incidence of 60° deviating from the
vertical). Due to the vents at the bottom side the IR floodlight
is not all-round splashproof!
A black and white CCD camera suitable for infrared must be
used as monitoring camera (sensitivity min. 0.5 lux). Colour
cameras are not suitable for infrared light illumination. The
opening angle of the camera lens should not be larger than the
radiation angle of the floodlight (max. 65°). Otherwise the ed-
ges of the picture appear darkened. For outdoor applications
an automatic iris lens with an aperture of 1 : 1.4 is recom-
mended for the camera.
4 Mounting
When choosing the mounting place please observe the
following items:
a. For outdoor applications mounting in a rain-protected
place is recommended (e. g. below a projecting part of a
roof). Always mount the floodlight bracket (5) to a horizon-
tal area. It must be secured that no water is able to pene-
trate through the vents (3)!
b. A mounting height of approx. 3 to 4 m is recommended.
Higher mounting results in a poorer illumination.
c. If a motion detector is connected to the camera, the ca-
mera should be mounted approx. 3 m from the IR flood-
light. Thus, insects attracted by the infrared light cannot
trigger a false alarm.
1) Screw off the floodlight from the bracket, and mount the
bracket to a suitable place. Then screw the floodlight to the
bracket again.

2) Align the floodlight and the camera to the desired monitor-

Warning: Only use the original screws. Two replace-
ment screws are included in the delivery. Longer
screws can get into contact with mains voltage carry-
ing parts and thus lead to a lethal electrical stroke!
