MX-Overvoltage-Protection-Box: Quick Install
Surge Protection for
MOBOTIX IP Cameras
• Protects MOBOTIX cameras against surges of up to
4 kV on the PoE network cabling
• For patch cable to patch cable or patch cable to
installation cable (MX-Overvoltage-Protection-Box
-LSA)
• Complete set including mounting supplies
Weatherproof network connector (IP65) with surge
protection of up to 4 kV for MOBOTIX IP cameras;
ideal for replacing MX-Patch-Box

Surge Protection for MOBOTIX IP Cameras
Surges are voltages that exceed the allowed voltage range for MOBOTIX IP cameras. The max. voltage for
PoE, for example, is 57 V. Surges do not necessarily result in irreparable damages to MOBOTIX IP cameras.
Only if the voltage is exceeded by a multiple of the allowed value, or if the surge is present for a longer
period of time or even permanently, damages are unavoidable.
PoE, for example, is 57 V. Surges do not necessarily result in irreparable damages to MOBOTIX IP cameras.
Only if the voltage is exceeded by a multiple of the allowed value, or if the surge is present for a longer
period of time or even permanently, damages are unavoidable.
Examples for Causes of Surges
• Direct lightning strike into the installation itself or the network cable
• Lightning strike into the power supply or the ground in the vicinity (within a radius of 100 km/62 mi)
• Switching of high loads, especially if network and power lines run side-by-side
• Lightning strike into the power supply or the ground in the vicinity (within a radius of 100 km/62 mi)
• Switching of high loads, especially if network and power lines run side-by-side
Surge Protection
In order to reduce the danger of damages resulting from surges, a specialist should establish a surge
protection concept and implement such a system. Such a system consists of several surge protection zones,
where each zone contains specific and generally applicable countermeasures. These range from lightning
capture devices and double-shielded network cables to fine-level surge protection for end devices. When
selecting the countermeasures, not only technical, but also economical aspects need to be considered in
order to find the proper balance between protection and costs.

The
MX-Overvoltage-Protection-Box-RJ45 and MX-Overvoltage-Protection-Box-LSA can be used in most
of the protection zones and provide a cost-efficient protection against surges. It is generally recommended
to install an MX-Overvoltage-Protection-Box if MOBOTIX cameras are installed outside of buildings. These
devices protect MOBOTIX cameras against short surges of up to 4 kV.

Caution
• The cable between the MX-Overvoltage-Protection-Box and the MOBOTIX camera must not be
longer than 50 cm/19.7 in.
• An MX-Overvoltage-Protection-Box protects against surges of up to 4 kV on a network patch or
installation cable, but not against direct lightning strikes.

MX-Overvoltage-Protection-Box-RJ45:
Patch Cable/Patch Cable
The patch cables with integrated sealing rings (available from MOBOTIX in different lengths) are
simply inserted into the RJ45 connectors and fastened using the bayonet catch (1 patch cable to
end device, 1 patch cable to PoE switch/injector). The ground wire is attached at the center (only
qualified electricians are allowed to do this!).
