- The device is traditionally installed at the most convenient height for management - 1,5-1,6 m. First lay the wiring, take it to the gate and into the house - the "twisted pair" for the Internet (if necessary) and the four-wire cable, hidden in the corrugated hose. The power cord on the calling panel is laid out imperceptibly from the electric lock inside the gate.
- In the house for the return part, a 220 V power cord, twisted pair and four-wire, combined into a corrugated hose, are separately displayed.
- An electric lock is installed, from which the power cable goes to the street for an overlay for a call.
- A niche is cut for the outside of the product with the help of a grinder and chisels.
- The contacts of the calling part are connected to audio, video intercom channels and a lock in the street. In the niche is inserted and the lock control unit (abbreviated BLS).
- All connections are hidden under the outer panel body, after which it is fixed to the fixing plate.

Connection scheme for a doorphone in a private house
Before installing a door phone in a private house, you need to draw a diagram of its connection. The main points when connecting:
- This is a standard scheme for connecting a doorphone with a lock in one circuit: from a receiver located in the house, you need to lay several wires. If you plan to install only an audio device, you need a three-wire cable, to mount the model with a video signal you need a four-wire cord. Both parts of the intercom are connected to 220 V with the help of step-down power supplies.
- Two wires are responsible for the power supply, another pair for the audio and video signal. To use the intercom, each additional device is connected in series to the circuit by a four-wire cord.
- Unlike wired models that are powered by a doorphone monitor, a wireless street model not equipped with batteries must be additionally connected to the network and the Internet cable. Next to the place of its installation, there must be an outlet or an electric cord. If the power supply is powerful, then the electric lock and the call pad can be connected to a single 200 V source, as indicated in the diagram.
