2.10 Notes

2.10.1 Cleaning Instructions

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.

Cleaning the Lens

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

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

the lens' focus if required.

2.10.2 Wiring, Fire Prevention, Lightning and Surge Protection

When installing the wiring in or out of buildings, make sure you always adhere to

the relevant regulations on wiring, fire prevention and protection against lightnings.

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.

Find more information on the subject at the International Electrotechnical Com-

mission (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 you follow these guidelines:

• 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

below 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,
