Philips LDH 0462/00 (VCM 6459/00T) Information Sheet
Power Connector
The camera can operate from either a 24V AC or 12V DC power supply. Connection is on an
8-pin mini-DIN socket.
AC Operation: Use pins 6 and 8.
DC Operation: Pin 5 is +12V DC. Pin 2 is GROUND.
Iris Connection
A standard iris lens (one that has a built-in video amplifier and motor drive) can be connected
to the 3-pin mini-DIN connector on the rear of the camera.
Pin 1: GND
Pin 2: Video Out
Pin 3: +12V DC
The camera also has a standard 4-pin iris connector for use with a passive iris lens.

Set the lens distance to infinity
Aim the camera at an object that is at least 15m away.

Loosen the lens mounting ring by means of the small set-screw on top of the camera
front.

6.
Turn the lens with the mount adjustment ring until the video picture is in focus. This is
most accurate when the iris is fully open.
Tighten the lens mount ring by means of the set screw.
Iris Adjustment (Manual iris lenses)
1.
2.
3.
4.
Install the camera in the position where it will be used. Aim and focus the camera on
the area to be monitored.
Set the iris to its minimum aperture. The camera will now show a low contrast picture
with ‘noise’.
Open the iris slowly. The picture contrast will improve and the ‘noise’ will gradually
disappear.
Set the iris to a position at which the details in the larger white parts of the picture are
not washed out.

This specification has been derived from various sources, principally from the specification of
the similar LDH0460/00 camera. I cannot therefore guarantee that this specification is
