There is a possibility to happen noise disturbance to camera if the following things are near here:
- 120 V (for U.S. and Canada) or 220 V – 240 V (for Europe and other countries)
or higher voltage power line (lamp line)
- Transformers and motors,
- Strong electric field from a TV or radio antenna
In this case, conduct the power distribution work to keep a distance of 1 m {3.28 feet}
or more (depending on voltage) or conduct the electric conduit work separately
(Always make connection with the joint part of the metal pipe, and connect the metal pipe with grounding).
