Adjusting Zoom, Focusing The Image - Sygonix 1359880 Bedienungsanleitung

Connection
The camera is equipped with a connection cable with two connectors on
the end:
• BNC connector: The video signal (PAL) is available via this connector. Use
an adapter if you do not have a BNC cable for this connection.
• Round low-voltage socket: The external voltage/current supply is con-
nected to this socket. Make sure you use only a power supply unit with
a stabilised output voltage of 12 V/DC (direct current) (see also section
"Technical data" at the end of the operating instructions).
Pay attention to the correct polarity of the connector for the power
supply (inner contact = plus/+, outer contact = minus/-); otherwise
the camera will be damaged; loss of warranty/guarantee!
If you install and use the camera in outdoor areas, the two connec-
tors may only be placed in a location that is protected from humidity
(in dry indoor areas). Otherwise, the connectors will corrode.
Set the correct input channel on the display device, to display the camera
image.
Afterwards, adjust the camera carefully in order to be able to monitor the
desired area.
In the dark, the IR LEDs are activated automatically. The IR light is not vis-
ible to the human eye. Please bear in mind that because of the method
used, the image recorded at night (when the IR LEDs are activated) is not in
colour, but rather in black and white.

Adjusting zoom, focusing the image

The camera is equipped with a manually adjustable zoom lens, it is also
possible to focus the image.
On the underside of the camera, there are two Allen screws for this pur-
pose, which can be turned using the provided Allen key. Do not use any
force when turning!
Using the "ZOOM" screw, you can adjust the desired zoom range; using the
"FOCUS" screw, you can focus the image.
It may not be possible to focus the image with the "FOCUS" screw
when the "ZOOM" screw is at the end positions.
In this case, turn back the "ZOOM" screw a little.
Cleaning
Occasionally, clean the camera from dust and dirt, especially the front
screen. Use a clean and soft cloth, moistened with water. Do not rub too
hard, since otherwise scratch marks will occur on the glass; this will cause
deterioration in the image quality!
Never point the jet of water from a garden hose or a high pressure cleaner
at the camera; never use aggressive cleaning agents.
Tips and notes
• Install the camera so that it cannot be reached without using auxiliary
means.
The same applies to the connection cable. Ideally, it should be laid in a
plastic or metal pipe.
• Longer cable lengths cause deterioration in the video signal. In this case,
use a suitable amplifier.
If the cable used to supply the power is too long, the voltage will drop, and
thus the operating voltage for the camera will no longer be sufficient. This
may lead to stripes in the image or to a loss of signal. If necessary, use a
cable with a larger cross-section to reduce the voltage drop.
Disposal
The product must not be disposed of in the household waste.
Please dispose of the product, when it is no longer of use, accord-
ing to the current statutory requirements.
