A video intercom for a private house: the kit with a lock and gate

A private-house video intercom is four parts: the door station at the gate, the monitor in the house, the lock on the gate and a power supply. Plus the cable between them — and the cable is most often the weak point: the station and monitor connect directly, and the gate can be 20–50 meters away across the yard.

Out-of-the-box 'station + monitor' kits cover only talking and video. Opening the gate is a separate lock with its own power and an exit button on the yard side: plan it into the project from the start rather than 'add it later' — or you will dig up the walkway again for a single cable.

The station at the gate lives under sun, rain and frost, so check the ingress protection rating (IP65 and up) and operating temperatures. The second outdoor enemy is backlight: the sun behind a visitor turns the face into a silhouette. Stations with wide dynamic range help, and so does placement — not facing due south.

Choose the viewing angle by task: a narrow one shows the face large, a wide one shows who stands nearby and what happens at the gate. For a house the wide angle (120° and more) is more practical — it partially replaces an entrance camera. A metal body survives hail and curious children alike.

Nine times out of ten a gate gets an electromechanical lock: during a blackout it stays LOCKED and opens with a mechanical key. A magnetic lock is the opposite — it opens when power fails: a plus for evacuation doors, a security hole for a private gate.

An outdoor lock must be built for outdoors: moisture-protected and tolerant of the gate sag that inevitably develops over time. Fit an exit button on the yard side and a closer right away: a lock that 'almost latched' is not locked at all.

An analog four-wire kit is simpler and cheaper: a station, a monitor, four cores — it works for decades with no network and no configuration. It is enough when 'heard the bell — looked — opened' suits everyone at home.

An IP intercom adds the main thing: the call reaches your smartphone wherever you are — a courier at the gate while you are at work: you see, talk and open. Plus integration with cameras and access control into one system. The price is network setup and internet dependence — though the intercom itself keeps working locally without it.

The typical mistake is thin cable on a long run: over 30–50 meters weak cores sag the station's power and video picks up noise. Lay cable with cross-section headroom to the gate (separate thick cores for the lock), in conduit, at a depth a shovel will not reach.

Count the lock's power separately from the intercom: an impulse lock draws several times its nominal current at the moment of opening, and a weak power supply sags together with the picture. If gate automation is planned, put its cables into the same trench — digging twice costs more.

We build private-house intercom systems turnkey: the gate station, the monitor (or two, per floor), an electromechanical lock with an exit button, the run in conduit, and calls set up on the whole family's phones. The engineer's visit is free in Tashkent — we look at the yard and name the exact configuration.

Our Tashkent warehouse holds over sixty intercom items, the backbone being Hikvision's IP line: door stations, monitors, kits. We match the budget: from a simple analog kit to an IP system integrated with cameras and the smart home.
