Residential Access Control Systems, Designed, Installed, Monitored
Residential access control lets you manage entry to your property without relying solely on traditional keys. Depending on the setup, you can unlock doors and gates using a keypad code, fob, smartphone, fingerprint, or a video intercom, with the ability to grant and revoke access easily.
At Harpenden Alarms, we start with a free site survey to understand your entry points and day-to-day needs, then recommend a practical system that is secure, user-friendly, and professionally installed, with clear handover and ongoing support.
