• Outdoors: Installing the camera outdoors requires special precautions and
measures regarding the cables as well as lightning and surge protection (see
section 2.10.3,
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 30m
(33yd) for patch cables and 100m (110yd.) for installed cables.
• Avoid 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.
2.10.2 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.
2.10.3 Lightning and Surge Protection
To prevent damage from lightning and surges, make sure you follow these guide-
lines:
• Lightning conductors: In areas exposed to lightning (e.g. on roofs), a dis-
tance holder (1m/3ft. higher, 1m/3ft. 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.
• Surge protection: Make sure you have installed proper protection against
electrical surges in order to prevent damage to the camera, the building and
the network infrastructure. This includes surge protectors for 19" racks, adding
an uninterruptible power supply (UPS) to the MOBOTIX camera and installing
surge arresters or similar for routers, switches, servers, etc.
2.11 Camera Accessories
Power supply (MX-SNT-E/U/GB/J/AUS01-30-RJ)
The MOBOTIX power supply is required if you do not
use a Network Power Rack or Network Power Box,
or a PoE-compatible switch or router.
Network Power Adapter (MX-NPA-3-RJ)
The Network Power Adapter allows injecting the po-
wer supply for the MOBOTIX camera into the net-
work cable. It thus allows using the network cable
for connecting to the camera and for remotely
supplying power (up to 100m (300ft)). The Network
Power Adapter is required, if you are using the uni-
