4.2.4 NOTE - Silicagel bag
As it is not always possible to avoid a situation where a certain amount of moisture remains in the opened casing, we
recommend using the enclosed bag of silicagel in such cases. It must be ensured that the gel is used appropriately,
i.e. opening the protective film too soon can lead to the silicagel becoming saturated in a very short period of time,
thereby making it ineffective.
. Before inserting the silicagel pack, please remove the aluminium protective sleeve around the pack, as the
silica gel is only effective without the aluminum protective sleeve.
. Insert the pack between the back of the casing and the camera holder.
3. The silica gel retains the residual moisture that accumulated in the casing during assembly in a moist climate.
4.3 Setup of the Image Sector
• Pull off the camera housing.
• Power up the camera and connect a monitor.
• Loosen Zoom adjustment knob and adjust the zoom setting.
• Loosen Focus is adjustment knob and adjust the focus.
• Tighten both locking screws when adjustment is done. Close the housing.
NOTE: For a precise adjustment of cameras installed outside it is recommended to place a ND (Neutral
Density) filter in front of the lens while settings are done. This opens up the iris and allows a setting
which is constant at changing light conditions due to the narrower depth of field.
