7 Maintaining and cleaning
7.1 Window cleaning
Surface dirt should be rinsed away with water and
then the window cleaned with a neutral soap diluted
with water, or specific products for spectacle lens
cleaning. These should be applied with a soft cloth.

This section describes how to install the camera
power supply kit inside the housing. It is possible to
install a number of different types of power supply.
The input voltage may be 230Vac or 115Vac while the
output voltage may be 12Vdc or 24Vac, 400mA.
Open the housing following the instructions given
previously (Fig. 01, page 5).
Position the power supply to match the attachment
holes provided on the inner side of the rear flange of
the housing.
Attach the power supply to the rear plate of the
housing using the screws supplied with the power
