What is the main job of a strong and weak current engineer in a real estate company?

This range is too large. Depending on what you do specifically, I think it is mainly divided into two types. Weak current and strong current are generally separated. Strong current refers to the configuration, installation, and debugging of the power supply line. Weak current mainly refers to network, access control, telephone, monitoring, and other such things. And as a real estate company, you may be involved in management work in this area. Many weak and strong currents are outsourced. I don't know exactly what situation you will encounter.
