• Do not direct the camera lens to the sun or strong lighting or light

reflection.

• Do not give the camera a great shocks or vibration, as this will

damage the camera.

• It is recommended that the camera be always used in locations

where the ambient temperature ranges from -10°C to +50°C and
humidity levels of less than 90% to ensure that no condensation is
formed.

• To clean, wipe with a dry soft cloth. Never use benzene, thinner or

chemically processed towel as the unit's plastic or other parts may be
deformed or discolored.

• When dust has settled on the camera's lens, lightly clean using a

commercial camera blower or cleaning paper.

• Installing the camera cables in close proximity to fluorescent lamps

or other electrical appliances can downgrade the picture quality. In
such cases, change the wiring.

• If there is a strong electric or magnetic field near the camera, such as

television transmission antennas, motors or transformers, this may
distort or roll the monitor picture. In such cases, run the entire wiring
route through metal conduit tubing.

• Do not install the camera in locations where solvents or chemicals

are used as the camera's dome cover may be deformed or
discolored.

• Use the external power supply unit of the following rating.

12 V DC, over 0.5 A
