system.
1. DESCRIPTION
The video transmitter is a flush mounting module that converts a video signal from a coaxial
system into a
Niko Access Control
video signal. The module also allows the video signal
to be amplified or attenuated.
System connection
For gain control
Camera coax connection
Camera power supply
The
video transmitter has to be
cabled in a 6-wire way
. Use a
twisted cable
for an
optimum image quality. Pay attention to the
diameter
of the wires in the cable, as this
determines the
maximum distance
that can be covered between the power supply and
the video transmitter.
Niko recommends using the following
cables
:
• JYSTY(-F2) min. 3 x 2 x 0.8mm (max. distance 200m);
• TVVF (-F2) min. 3 x 2 x 0.8mm (max. distance 200m);
• TPVF min. 3 x 2 x 0.6mm (max. distance 100m);
• UTP/FTP/STP 4 x 2 x 0.5mm (max. distance 70m).
Function of the wires to be connected:
• terminals
a & b
: communication bus (24 VDC)
• terminals
V1 & V2
: video signal
• terminal
P & M
(b): extra power supply (26 VDC)
Note!
Disconnect all power before installing the video transmitter. Do not connect
the unit to the power supply until installation is complete
