Ventilation
To prevent overheating of the device, keep free air circulation in the area where the camera
is located.
Cleaning
Use a soft, dry cloth for cleaning camera's external surfaces. It is acceptable to use some
detergent for removing persistent dirt, but not the volatile cleaners such as the alcohol-containing
solvents, benzene and so on, because of the risk to damage the camera's housing.
