M22M Camera Manual Part 1
2.8 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, fire prevention and protection against
lightning.
MOBOTIX recommends having MOBOTIX cameras installed only by specialists
accustomed to installing network devices and having proper respect for the perti-
nent regulations regarding lightning protection and
current technology for preventing damages from electrical surges.
Find more information 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).
2.8.1 Wiring
When installing the wiring, make sure you follow these guidelines:
•
Data cable:
Make sure you only use double-shielded
CAT 5/7 cable (S/STP) for Ethernet connections. Double-
shielded means that the cable as a whole is shielded
and that each twisted wire pair has its own shield.
•
Outdoors:
Installing the camera outdoors requires spe-
cial precautions and measures regarding the cables as
well as lightning and surge protection (see section
2.8.3, Lightning and Surge Protection ).
•
Wire lengths:
The cable segments must not exceed the maximum allowed
cable lengths in order to ensure proper data transfer (see section 3.3,
Connecting the Camera ). Maximum cable lengths should not exceed 30 m
(33 yd.) for patch cables and 100 m (110 yd.) for installed cables.
•
Avoid induction:
power lines or high-voltage wires, make sure you observe the minimum dis-
tances to the power cables.
2.8.2 Fire Prevention
When installing the power lines to the camera, make sure you always adhere to
the relevant regulations on wiring and fire prevention at the site of the installation.
2.8.3 Lightning and Surge Protection
To prevent damage from lightning and surges, make sure you follow these guide-
lines:
•
Lightning conductors:
tance holder (1 m/3 ft. higher, 1 m/3 ft. away from the camera) and proper
lightning conductors need to be installed in order to prevent lightning strikes
into the camera and to ensure that the energy of a lightning strike is properly
led to the ground.
