5.3. Power supply
IMPORTANT!
Before starting installation, ensure that the mains voltage and the rated voltage of
the camera are identical.
(1) Video signal (BNC)
(2) Power supply
12 V DC (5.5 x 2.1 mm)
The cameras have a 12 V DC power supply. Ensure correct polarity when connecting. A power supply
unit (round plug, 5.5 mm x 2.1 mm) is provided for the connection.
5.4. Connecting the video cable
In order to transmit the HD-TVI video signal from the camera to an HD-TVI recorder, an RG59 type
coaxial cable with BNC connector (male) must be connected to the connection labelled 'TVI'. The
cable length to the next device must not exceed 500 m (RG6) or 300 m (RG59).
To ensure optimum quality of the HD-TVI signal transmission, it is important that the
cable is neither kinked nor crushed at any point, and that its radius is adequate (min.
bending radius 6 cm).
Damage to the cable or porosity as a result of ageing can have a negative impact on
the quality of the signal or image (e.g. shadowing around the edges).
