Access Control Systems

An access control system decides who can open a gate or door, and when. Instead of a key, it checks something a person enters, carries or triggers, such as a code, a card, a phone call or a vehicle. We install and maintain these systems for residential, commercial and industrial properties.

Each type works differently. The pages below explain how each one works and where it fits.

Keypad Access Systems. Entry by a numeric code entered at the gate or door.

Intercom Access Systems. A visitor calls from the entrance and someone inside talks to them and lets them in.

RFID Access Systems. Entry by a card, fob or tag that the reader recognizes without contact.

Telephone Entry Systems. A visitor’s call is routed to a resident’s or tenant’s phone, which can open the gate.

Vehicle Detection Systems. Sensors that detect a vehicle so a gate opens on exit, or stays open while a car is in its path.

Many properties combine two or more of these, such as a keypad for residents and an intercom for visitors.
