6 Camera Maintenance

Proper maintenance will ensure consistent image quality over the life-span of the camera.

Take care not to touch or stain the dome cover, lens, or the mirror surface. If the one of these

surfaces is stained, use the following methods to clean:

•

Stained with dirt: Use an oil-free soft brush or blower to gently remove the dirt.

•

Stained with grease or fingerprints: Use a soft cloth to wipe gently the water droplet or the oil

from the dome cover. Then, use an oil-free cotton cloth or paper soaked with alcohol or

detergent to clean the lens from the center of the dome to outside. Change the cloth several

times to ensure the dome cover is clean.

Use a dry soft cloth to clean the unit's housing. If the unit is particularly dusty, use water to dilute a

mild detergent, apply the diluted detergent to a soft cloth, then gently clean the device. Finally, use a

dry cloth to wipe the unit dry. Do not use a volatile solvent like alcohol, benzene, or thinner; or use a

strong detergent with abrasives, which may damage the surface coating or reduce the working

performance of the unit.
