2.9.3 Changing Lenses

As described in section 2.9,

Lens Options

, the

M22M can be fitted with several MOBOTIX

lenses. Proceed as follows to change a lens:

• Unmount the lens cover by turning it

counter-clockwise.

• Loosen the lens' lock ring (if fitted) by turn-

ing it counter-clockwise.

• Remove the lens with the lock ring by

turning it counter-clockwise.

• Unscrew the lock ring (if present) from the

lens you just removed and screw it onto the

new lens.

• Screw the new lens with the lock ring (if present) back into the camera.

• If necessary, restore the power supply of the camera.

• Adjust the image sharpness according to the camera's live image on the

computer monitor. Never turn the lens to far into the lens mount and never

apply excessive force when doing so as this would damage the lens mount

otherwise.

• Tighten the lock ring by turning it in clockwise direction.

This procedure is the same for the M22M-Sec-CSVario and CS/C mount lenses,

albeit without the lock ring (not installed).

2.10 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 pertinent

regulations regarding lightning protection and fire prevention as well as the 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).

2.10.1 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.
