Securing the perimeter of your property begins at the gate. A gate intercom lets you speak with visitors and release the lock remotely, keeping your property secure without needing to walk down the driveway. Wired intercoms are costly to install due to the trenching required for cables.

Why Install a Wireless Gate Intercom?
Wireless intercoms offer a cost-effective, clean alternative. In 2026, homeowners can choose between local radio-based systems, Wi-Fi smart doorbells, or mobile network (4G/5G) intercom systems that call your smartphone from anywhere.
DECT vs Wi-Fi vs 4G: Understanding Wireless Technologies
DECT (Digital Enhanced Cordless Telecommunications) intercoms operate on a dedicated 1.9GHz frequency, similar to cordless house phones. They provide excellent range (150–250m) and are immune to Wi-Fi interference. However, they only communicate with a dedicated indoor handset.
Wi-Fi intercoms connect to your home network, allowing you to answer the gate from your phone. They are highly convenient but require a strong, stable Wi-Fi signal at the gate. 4G GSM intercoms use a SIM card to dial your mobile phone directly. They have unlimited range but require a monthly cellular subscription.
Integrating Gate Releases and Smart Locks
An intercom is only half the solution; you also need a way to open the gate. Most wireless intercom transmitters include a relay switch that connects to the gate controller's open/close terminals.
When you press the key button on your indoor handset or smartphone app, it triggers the relay, sending a low-voltage pulse to release the electric strike or activate the gate motor. Ensure your gate controller has backup battery storage in case of power cuts.
Overcoming Signal Obstacles & Weatherproofing
Stone walls, metal gates, and wet foliage block wireless signals. If installing a Wi-Fi intercom at a metal gate, the gate itself can act as a shield, completely blocking the signal. Install the antenna on a brick pillar next to the gate instead.
The outdoor call station must have an IP65 or IP66 weatherproof rating to withstand UK winters. Use silicon sealant around the backplate to prevent water ingress behind the call button, which can corrode the battery terminals.
