Please read these operating instructions carefully prior to
installation and keep them for later reference.
1 Applications
The camera TVCCD-257SET is specially designed for
video surveillance systems (CCTV). It is equipped with an
8.5 mm (
1
⁄
") image sensor and a lens with variable focal
3
length (4 – 9 mm). The rugged dome housing is weather-
proof (IP 66) and vandal-proof. Due to its flexible lens
adjustment (3-axis rotation), the camera is also suitable
for wall mounting.
The camera features automatic gain control (AGC),
backlight compensation, automatic white balance and an
automatic electronic shutter for exposure control. When
darkness falls, the 30 IR LEDs illuminate the surveillance
zone up to 15 m and the camera switches to black-and-
white mode.
2 Important Notes
The camera corresponds to all relevant directives of the
EU and is therefore marked with
.
CAUTION The infrared LEDs switch on in case of dark-
ness. When setting up the camera, never look directly
into the lit infrared LEDs from a close range. The infrared
light may cause eye irritation. However, the infrared radi-
ation is far below the emission limit and rated risk-free
according to EN 62471.
G
Protect the camera against extreme temperatures (ad-
missible ambient temperature range -10 °C to +50 °C).
G
For cleaning never use any aggressive detergents or
chemicals.
G
No guarantee claims for the camera and no liability for
any resulting personal damage or material damage will
be accepted if the camera is used for other purposes
than originally intended, if it is not correctly installed, or
if it is not repaired in an expert way.
If the camera is to be put out of operation defin-
itively, take it to a local recycling plant for a dis-
posal which will not be harmful to the environ-
ment.
3 Installation
1) Release the three screws of the dome (10) using the
wrench provided and remove the dome from the base
(4). To avoid scratches, leave the protective foil on the
dome while mounting the camera.
2) To find the optimum place of installation, a trial run is
recommended. For this purpose, put the camera into
operation provisionally (
chapter 4).
3) At the place of installation, drill four holes for mounting
the base. Fasten the base (4) with suitable installation
material. If the cable is not led through the wall or ceil-
ing, it may alternatively be led through the cable outlet
on the side of the base. For this purpose, remove the
cover screw (5) from the cable outlet. Seal the cable
outlet to prevent ingress of moisture.
4) After all adjustments have been made (
put the dome on the base and fasten it using the three
screws. Make sure that the camera is able to look
through the cutout in the mask of the dome.
4 Connecting and Aligning the Camera
1) Connect the BNC inline jack (2) via a 75 Ω coaxial
cable to the video input of a monitor. Observe the cor-
rect 75 Ω termination on the monitor or, in case of
series connection, on the last monitor. For a cable
length exceeding 100 m, it is recommended to insert a
video amplifier between the camera and the long cable
to compensate level loss caused by the cable.
2) Connect a regulated 12 V power supply unit with a min-
imum permanent rating of 350 mA to the inline jack (1).
TVCCD-257 SET
A low-voltage plug of 5.5 / 2.1 mm (outside / inside diam-
eter) is required. Always observe the correct polarity
(centre contact = +).
The connectors (1, 2) and the cable distributor (3) are not
weather-proof. In case of outdoor installation, protect
them accordingly.
3) Switch on the monitor. To optimally align the camera to
the surveillance zone, adjust its support. For this pur-
pose, release the two lateral screws (6) to tilt the cam-
era. After aligning, fasten the screws again. In addition,
it is possible to turn the support in the base and to turn
the camera around the lens axis. Always make sure
that the cable connections are not stretched or torn off.
4) Adjust the image cutout with the zoom adjusting ring
(7) and a clear image with the distance adjusting ring
(8). The corresponding adjusting lever is also a locking
screw: Release it before adjusting and fasten it after-
wards.
