ISDN-only operation
When operating the camera only at the ISDN, you need to install an additional ISDN
cable (see section 2.12,
Preparing the Installation ), then attach the power supply
using the pre-installed cable and the NET/10BaseT connector of the camera.
2.6 Power Supply of the MOBOTIX M12
In order to reduce the amount of cabling, you should always use the Ethernet cable
(NET/10BaseT) to inject power into the camera cabling (Power over Ethernet).
For smaller installations, the MOBOTIX Network Power Adapter
MX-NPA-3-RJ and
the universal power supply
MX-SNT-E/U/GB/J/AUS01-30-RJ is sufficient. Larger in-
stallations would benefit from one or more MOBOTIX Network Power Boxes/
Racks that are available for supplying power to 4, 8 or 20 cameras (
MX-NPR-4 , - 8
or - 20 ). See section 2.3, Camera Accessories , for more information on these and
other items or open shop.mobotix.com (Products> Accessories section).

Caution
In contrast to the MOBOTIX M10, it is not possible to use an ISDN

split cable and MOBOTIX PoE products (see section 2.3, Optional
Accessories), the power can be injected into the ISDN data cable
(8-wire cable required).

Advantages of the MOBOTIX PoE Products
• Zero maintenance and reliable as the systems do not require
fans.
• Higher reliability of the system as a whole, since standard swit-
ches without PoE can be used (lower risk of failure).
• Easy installation on DIN rails (
MX-NPR-4 ) or in 19" racks
(
MX-NPR-8/20 ).
