Intercom Gate Entry System UK¶

Comprehensive guide to intercom gate entry systems for UK homes, including audio-only, video, SIP-based, and 4G options for electric gates.

Intercom System Types and UK Market Options¶

Intercom gate entry systems allow visitors to announce themselves at the gate and be granted entry remotely by the resident. In the UK, audio-only intercoms remain the most affordable option at £150 - £400 installed, but video intercoms now dominate the market with prices from £300 to £1,200 for a colour camera and indoor monitor setup. Leading UK brands include BFT (Avel), Came (BXS), DoorHan (Ultra), and Fermax. 2-wire analogue systems are common in existing buildings, while SIP-based IP intercoms connect over the property's existing network and support smartphone integration via apps such as 2N Mobile Key or Came Connect. For rural UK properties without reliable broadband, 4G intercoms with a built-in SIM card cost £500 - £900 and function independently of home Wi-Fi. Most modern units include a 1080p camera with wide-angle lens, infrared night vision, and motion-activated recording - features recommended by Secured by Design for new-build developments.

Wiring, Networking and Installation Best Practices¶

Installing an intercom system at a UK gate requires routing cable from the gate to the indoor station - typically 4-core or 6-core screened cable for traditional analogue systems, or a single Cat6a shielded cable for IP-based units. The maximum cable run for analogue systems on 18 AWG wire is approximately 100 m; beyond that, a signal booster may be required. Surface-mounted back-to-back posts with integrated intercom and keypad are a popular solution for pillarless driveways, costing £400 - £800. For IP systems, the gate station must be on the same VLAN as the indoor monitor and powered via Power over Ethernet (PoE) or a local 12 - 24V DC supply. All external cable joints should be made in a weatherproof IP66 junction box. Post-installation testing should verify microphone echo cancellation, speaker volume adjustment, and unlock relay timing (typically 3 - 5 seconds). Smartphone apps must be configured on the same Wi-Fi network as the base unit during initial setup.
