Introduction of home video intercom doorbell
In simple terms, a home video intercom doorbell is a doorbell that can be seen outside the room and can talk to each other when someone rings the outdoor bell.

How to install the home video intercom doorbell?
After many consumers buy home video intercom doorbells, they do not know how to choose the installation location. When choosing an installation location, we will cover the following points:
1. The communication method between the outdoor unit and the indoor unit is 2.4Ghz wireless connection. The penetration of the connection signal to the iron door is very weak, so the outdoor unit must not be installed on the iron door. Indoor and outdoor units are
usually installed at optimal distances. Do not exceed three floors; indoor units and indoor units need to communicate with each other at most, usually up to three walls can be connected;
2. The waterproof level of the outdoor unit reaches IP55, but wind and rain, viewing angle, ventilation and other factors should also be considered during installation;
3. The general temperature of the outdoor unit is between -10°C and 50°C, and the indoor unit is suitable for -0°C + 40°C, so environmental factors must be considered during installation;
4. The power supply mode of the outdoor unit and the indoor unit is mainly connected to the power supply and the battery, and the layout of the external power cord should be paid attention to during installation;
5. The outdoor unit should be installed at a position 1.4~1.7m from the ground to avoid sunlight entering the lens as much as possible.
