Device interfaces
2.4.1
Analogue video inputs A1...4 and B1…4 – connection of analogue CCTV cameras
The interfaces of the analogue cameras are separated into two camera groups (A and B). Up to eight
standard
commercial
CCTV
cameras
can
be
connected
via
the
BNC
connections
IN A1...4 to IN B1...4 (rear of device) provided they have BNC connectors and deliver an analogue
CCIR standard (CVBS, PAL/NTSC) signal. The operating voltage for the cameras is provided by the
MR3180 recorder itself (12V).
Before video footage can be recorded from a camera (analogue and IP), video recording for this
camera has to be explicitly activated in the Central Monitoring Software (see configuration chapter).
Note that you can only ensure a stable camera power supply of 12 V if the power supply to the
recorder is always over 13V.

This interface supports a bandwidth of 100 Mbit
Pinout of the RJ45 network interface
Using both Ethernet interfaces LAN 1 and LAN 2 it´s possible to connect the device to other external
devices (via patch cable (CAT 5 or higher)). This might be:
A computer
-
for configuration and/or control through the CMS
External devices
-
such as a WLAN-modem, a switch or something else
For stationary installation with more than one IP network camera it is recommended that you use a
switch for the connection to the network cameras. For such an installation use only the LAN 3
interface at the rear panel! This interface is designed vibration resistant.
