What are the points of attention when installing a video door?

1. Don't hit all parts vigorously or fall to the ground, otherwise failure will have a bad influence on later use.

2. The place where the video doorbell is installed must be careful not to be exposed to direct sunlight, and to avoid being corroded by wind and rain.

3. If you don't pay attention to soiling the outer layer, many people will wipe the lens with a wet tissue. This is wrong. The lens must be protected from moisture, otherwise the internal components will be corroded.

4. However, if the image of the doorbell is not clear after installation, you need to check whether there is electromagnetic interference around it.
