M26 Camera Manual: Installation
2.1.5 Wiring, Fire Prevention, Lightning and Surge Protection
When installing the wiring inside or outside of buildings, make sure you always adhere to
the relevant regulations on wiring, re prevention and protection against lightning.
MOBOTIX cameras are protected against the eects of small electrical surges by a range of
measures. These measures, however, cannot prevent the camera from being damaged when
stronger electrical surges occur. Particular care should be taken when installing the camera
outside to ensure proper protection against lightning, as this also protects the building
and the entire network infrastructure.
MOBOTIX recommends having MOBOTIX cameras installed only by certied specialists accus-
tomed to installing network devices and having proper respect for the applicable regulations
regarding lightning protection and re prevention as well as the current technology for
preventing damages from electrical surges.
Guidelines for Wiring
•
Data cable: Make sure you only use double-shielded CAT5 or
higher cable (S/STP) for Ethernet connections.
• Outdoors: Installing the camera outdoors requires special
precautions and measures regarding the cables as well as
lightning and surge protection (see below).
•
Wire lengths: The cable segments must not exceed the max-
imum allowed cable lengths in order to ensure proper data
transfer (see Section 2.7).
•
Avoiding induction: When running data cables parallel to existing regular power lines or
high-voltage wires, make sure you observe the minimum distances to the power cables.
Fire Prevention
When installing the power lines to the camera, make sure you always adhere to the coun
-
try-specic regulations (e.g. VDE in Germany, IEEE in the USA) in eect on wiring and re
prevention at the site of the installation.
Lightning and Surge Protection
In order to avoid damage to MOBOTIX cameras from overvoltages, you should always install
the MX-Overvoltage-Protection-Box. This competitively priced and weatherproof network
connector provides reliable protection against overvoltages of up to 4 kV; the box is easily
installed in the Outdoor Wall Mount, for example (see Section 1.5.8, «MX-Overvoltage-Protection-
Box»).
More information is available at an institution such as the International Electrotechnical
Commission (IEC, www.iec.ch) or at a manufacturer of protection devices against lightning
and electrical surges, such as Dehn (www.dehn.de).
