WARNING!
If the camera is mounted ball down, it is essential that the connector and base area of the
camera are completely sealed from water ingress. Any water getting into the connector is
liable to cause corrosion to the connector pins, leading to unreliable operation of the camera
unit.
F.01U.249.416 | 1.1 | 2012.03
Ensure that the mounting surface is capable of supporting the combined weight of the
camera and mounting hardware under all expected conditions of load, vibration, and
temperature. MIC612 cameras must be secured to one of the following surfaces:
– Concrete Solid/Cast
– Concrete Masonry Unit (Concrete Block)
– Brick (all types)
– Metal (Steel/Aluminum, minimum 1/8-in. thick)
Note: If the camera is positioned in a highly exposed area where lightning strikes may
occur, it is recommended to install a lightning conductor within 0.5 m of the camera and
at least 1.5 m higher than the camera. The construction of the housing itself is capable of
coping with secondary strikes. If the correct lightning protection is applied, no damage to
the internal electronics or camera should result. An earth bonding connection to the case
also provides protection against damage from secondary strikes. (See step 8.)
Fit the mounting brackets securely, observing all appropriate safety precautions and local
building regulations.
Carefully lift the camera to the mounting point.
Attach the security attachment point to a safety chain (not supplied).
Attach the safety chain to a secure part of your mounting structure.
Connect the female 14-pin connector end of the shielded composite cable to the male
plug in the base of the camera. Screw the cable connector sleeve onto the plug until it is
firmly secured (approximately four (4) turns from the start of thread engagement).
Earth the camera using one of the securing supplied bolts. Only earth the camera at a
single point to prevent earth loops and video distortion (hum bars), caused by electrical
interference, from appearing on the camera picture in the control room. Please note the
following:
– The camera module and housing are electrically isolated, so the housing should be
safety earthed regardless. The safety earth should be a bonding connection (for
example, one of the securing bolts) to the camera's outside case, and should be
attached to the Earth terminal post on the PCD base of the camera.
– If the system is copper throughout and the camera pictures are fed back to the
control room via coaxial copper cable, then the camera should be earthed only at the
video termination point in the control room. In this case, the "Earth Link" on the PCB
should be broken. Refer to
– If the video is transmitted back to the control room via some non-electrical
connecting medium (for example, fiber optic, radio, or microwave link), then the
camera should be earthed at the transmitter point in the power supply unit. The PSU
"Earth Link" may be used for this purpose.
– If dual earthing is unavoidable, then a video isolation transformer should be fitted
between the two earths.
Use M8 x 20 mm stainless steel nuts, bolts, and washers to secure the PCD base of the
camera to the mounting bracket. An additional Nebar gasket or suitable silicone sealant
can be used to ensure a water tight seal between the base and mounting surface. Tighten
all bolts securely.
