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.
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
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-ecient 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
MX-Overvoltage-Protection-Box-RJ45:
Patch Cable/Patch Cable
The patch cables with integrated sealing rings (available from MOBOTIX in dierent 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!).

Drilling Template for VarioFlex Wall Mount
with MX-Overvoltage-Protection-Box
1. Attach the box
Attach the MX-Overvoltage-Protection-Box-LSA at the
mounting position with the cable ports pointing down-
wards and open the lid of the box (three screws).
2. Connect ground wire
Open the terminal screw (red circle in figure) using a
regular screw driver. Strip the insulation of the ground
wire for approx. 5mm/0.2in and push the wire through
the eight-wire plug at the left. Insert wire into terminal
and fasten terminal screw.
3. Prepare the installation cable
Cut the installation cable to size, push it through the
cable plug 5to 7mm in the center, strip the cable for
at least 35mm and separate the individual wires of the
cable into twisted pairs with 20mm shielding. Wrap
the shield mesh around the cable sheath 10mm wide
so that it can rest on the contact plate of the board.
The cable will be fastened with a cable tie later on.
4. Feed the cable into the box
In order to prevent humidity entering the box, the rub-
ber sleeve needs to be tight against the cable. Guide
the supplied cable tie through the two cable slots as
shown and pull the cable tie tight around the cable
shield to provide proper strain relief.
5. Connect the cable wires
Use an LSA PLUS wire insertion tool to insert the in-
dividual wires into the LSA terminal. Decide on using
either the EIA/TIA-568A or B wiring standard as in the
rest of the building. The color code sticker in front of
the LSA terminal shows both standards.
If no LSA PLUS tool is available, you can use a tool with
interchangeable blades (LSA/Krone blade with setting
"Low Impact").
6. Attach the patch cable, close box
Remove right-hand bayonet catch and sealing plug,
insert MOBOTIX patch cable into the cable port and
secure it using the bayonet catch as shown. Only use
MOBOTIX patch cables with integrated sealing ring!
Mount the cover back onto the box (torque 0.4Nm).
