Device interfaces
2.4.1
Analogue video inputs 1 ... 4 – connection of analogue CCTV cameras
Up to four standard commercial CCTV cameras can be connected via the BNC connections IN 1 to
IN 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 MR3140
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.

Pinout of the RJ45 network interface
Using the RJ45-interface (LAN, Ethernet) and a patch cable (CAT 5 or higher) you can connect the
device with other external devices. This might be:
A computer
-
for configuration and/or control through the CMS
External devices
-
such as a WLAN-modem, a switch, a single IP-camera
or several IP-cameras over a switch
Connection of IP-cameras
Up to 12 IP cameras can be connected via the LAN interface and an external switch (see system
diagram on page 4). Video recording can be activated for up to 8 IP cameras, the remainder can be
set up in parallel to provide video pictures on a monitor.
Please note that the device does not support Power over Ethernet (PoE). Depending on the type of
cameras used (e.g. AXIS 209 FD-R) their power supply has to come via a separate power supply
unit or the PoE supply belonging to the external switch. Consult the relevant camera manual for
power supply details.
