9. Maintenance and cleaning

Before cleaning the housing of the surveillance camera, separate it from the mains
voltage and disconnect the mains adapter from the mains socket.
To clean the outside of the camera, a dry, soft and clean cloth is sufficient. For
heavier soiling on the camera, you can moisten the cloth slightly with lukewarm
water.
Clean the lens very carefully, you may otherwise scratch it.

mal windows, sheet steel
shelves, other radio devices
