Intercom Systems

What the system is for

Gates and doors are opened without knowing who is outside, and multi-unit properties struggle with visitor access.

An intercom answers a simple question: who is at the gate? The right arrangement depends on the entry point, the distance to the occupants and how many units share the entrance.

• Visitors identified by audio, or by audio and video, before the gate is opened
• Communication between the entry point and the people inside
• Controlled admission instead of opening a gate to unknown callers
• Calls routed to the correct unit on multi-unit properties, where the system supports it
• Door or gate release from inside where suitable hardware is fitted

Typical premises

• Homes
• Apartments
• Offices
• Gated developments

What an intercom system usually includes

Entry communication is built from a station at the entrance, one or more answering points inside, and the cabling and power that link them.

• Door or gate station

  The outdoor unit visitors use — position, weather exposure and mounting height all matter.

• Indoor stations

  Monitors or handsets where calls are answered, placed where people will actually hear them.

• Multi-unit arrangements

  Where an entrance serves several units, the calling arrangement is planned around the building.

• Door or gate release

  Locking or gate hardware, where release from inside is part of the requirement.

• Cabling, network and power

  The links between station, monitors and supply, planned for the distances involved.

Unit capacity, app or network features and remote-release capability differ by system. We confirm what a specific model supports before it is quoted.

System design considerations

• Entry points

  A pedestrian door, a driveway gate and a shared lobby each call for a different station and position.

• Audio or video

  Seeing a caller changes how admission decisions are made; audio-only can be enough on some entrances.

• Where calls are answered

  Indoor station positions decide whether a call is actually heard — kitchens, bedrooms and reception desks differ.

• Distance and layout

  The run between gate and answering point influences cabling and the type of system that suits.

• Multi-unit requirements

  Apartments and gated developments need a calling arrangement planned around unit numbering and the shared entrance.

• Cable routes

  Getting a cable from the gate to the building is often the real constraint, especially on finished properties.

• Power

  Both the outdoor station and the indoor units need supply arrangements planned into the install.

• Gate and lock release

  If the intercom must open something, the existing gate motor or lock is checked for compatibility first.

• Working with access control

  Intercoms often sit next to a reader so residents use a credential while visitors call — worth planning together.
