3. PRECAUTIONS

Do not direct the camera toward the sun or other extremely bright objects.

It is recommended that the camera be always used in locations where the ambient temperature ranges from

●

0 ゜ C to +40 ゜ C and humidity is less than 90%.

●

the camera may be discolored or deformed.

To clean the camera lens, use an ear syringe or photographic lens tissue to blow or wipe away dust or dirt.

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.
