2.11 Notes

2.11.1 Cleaning Instructions

Cleaning the Lens

If the lens is dirty from the installation process, clean the lens using a lint-free cot-

ton cloth. Make sure that the lens is still in focus after cleaning and adjust the lens'

focus if required.

Cleaning the Dome

• In order to protect the dome from being scratched and from getting dirty,

only handle the dome using a soft cotton cloth or the protective plastic of the

camera's shipping box.

• You should clean the dome at regular intervals. Always use a lint-free cotton

cloth for this purpose.

• If the dirt is more persistent, add a mild alcohol-free detergent without abra-

sive particles.

• Make sure you instruct cleaning personnel on how to clean the camera.

2.11.2 Wiring, Fire Prevention, Lightning and Surge Protection

When installing the wiring inside or outside of buildings, make sure you always ad-

here to the relevant regulations on wiring, fire prevention and protection against

lightning.

MOBOTIX recommends having MOBOTIX cameras installed only by certified spe-

cialists accustomed to installing network devices and having proper respect for the

applicable regulations regarding lightning protection and fire prevention as well

as the current technology for preventing damages from electrical surges.

More information is available at an institution such as the International Electro-

technical Commission (IEC, www.iec.ch) or at a manufacturer of protection devices

against lightning and electrical surges, such as Dehn (www.dehn.de).

Wiring

When installing the wiring, make sure to follow these guide-

lines:

• Data cable: Make sure you only use double-shielded

CAT 5/7 cable (S/STP) for Ethernet connections.

• Outdoors: Installing the camera outdoors requires spe-

cial precautions and measures regarding the cables as

well as lightning and surge protection (see further be-

low in this section).

• Wire lengths: The cable segments must not exceed the maximum allowed

cable lengths in order to ensure proper data transfer (see section 3.3,
