Intercom Installation for Doors & Gates

What's included

What an intercom installation actually involves

The first decision is door or gate: a unit right at the entry, or one further out at the boundary that needs its own cable run or wireless link back to the house. From there it's mounting the outdoor station at a sensible height, running power and data, installing the indoor unit or pairing the app, and, where there's an electric lock or gate motor, wiring in the release so you can let someone in without walking out yourself.

Once it's connected, we test the video, audio and release function from both the indoor unit and the app, and make sure the picture and two-way audio are clear before calling it done.

Door intercoms vs gate intercoms

A door intercom is the simpler of the two: one outdoor station at the entry with a camera, speaker and a release for the door itself, usually a shorter cable run back to the indoor unit or router. A gate intercom sits further from the house, which means a longer cable run (or a wireless bridge where trenching isn't practical) and, in most cases, pairs with an existing electric gate motor or a lock release you're adding at the same time.

Typical install scenarios

• Single-storey home, front door: outdoor station beside the door, indoor unit or app-only setup, short cable run through the nearest wall cavity.
• Gated driveway: outdoor station at the gate post, cable run (or wireless link) back to the house, integration with the gate motor's lock release.
• Small business or office: intercom at the front entry so staff can screen visitors or after-hours deliveries without leaving the desk.
• Warehouse or industrial gate: intercom at a roller door or boundary gate for managing deliveries and contractor access without someone walking out to meet every vehicle.
• Multi-tenant or granny flat setup: a system with more than one indoor handset so different parts of the property can answer independently.

What affects the price

The main factors are door vs gate, the length and difficulty of the cable run, whether an electric lock or gate motor already exists or needs adding, the number of indoor handsets, and whether you want app access in addition to (or instead of) an indoor unit.

Before install day

Know roughly how far the gate is from the house if it's a gate job, whether there's already power near the gate post, whether you want app access, indoor handsets, or both, and who in the household or business needs to be able to answer and release.

Common mistakes with DIY or cheap installs

Outdoor stations mounted where direct sun washes out the camera in the afternoon; gate units run on underpowered cable that works fine in testing but drops out over a long run; no weatherproofing on outdoor cable entry points; and cheap units with laggy audio that make it hard to actually understand who's talking.
