Audio Door Entry Systems

This wired audio door entry option centres on a Mercury two-way intercom, a battery-powered unit that links an entrance point to an indoor handset for clear two-way speech. It suits a front door, gate or small office reception where you want to check and talk to a caller before letting them in, without the added wiring or screens of a full video setup. Stock comes from AVSL.

Audio door entry, kept simple

An audio door entry setup lets you check who is at the door and speak to them before you open up, using sound alone. A unit at the entrance links to a handset inside, so a caller at a front door, gate or reception can press to call and you can answer with clear two-way speech. There is no screen and no camera to set up, which keeps both the wiring and the day-to-day use straightforward.

How a wired intercom works

The entrance unit and the indoor handset are joined so that voice travels both ways. A visitor speaks, you reply, and you decide whether to grant entry. Wired operation means the link stays steady and does not depend on a network or signal, which suits a fixed point such as a main door or a small office.

Where it suits

Audio-only entry works well where you want a quick, reliable way to vet callers without the added kit of video. Homes, flats and modest commercial doors all benefit from being able to talk first and open second. It is also a sensible starting point if you want voice contact now and may add other access measures later.

Fitting and placement

Mount the entrance unit at a comfortable height by the door or gate, and site the handset somewhere central indoors so calls are easy to hear and answer. Keep the run between the two parts tidy and protected. If you are unsure about the wiring or the best position, a qualified installer can set things up cleanly.

Choosing your setup

Think about the door or gate you want to cover, where you will answer from, and whether voice alone meets your needs. If clear speech and a simple install matter most, an audio system is a practical choice. Free UK delivery over £99, worldwide shipping.

Frequently Asked Questions

What is an audio door entry system?
It is an intercom that links a unit at your door or gate to a handset indoors, letting a caller speak to you and you reply before you open up. It uses sound only, with no camera or screen involved.

How is it different from a video system?
Audio entry handles speech alone, so you hear and talk to a caller but do not see them. That keeps the wiring and the controls simpler. A video system adds a camera and a monitor so you can also view who is there.

Does it need a network or WiFi to work?
No. A wired audio intercom connects the entrance unit directly to the indoor handset, so it works on its own link rather than relying on a network or wireless signal.

Where can I use an audio intercom?
It suits a front door, a gate or a small office reception, anywhere you want to check and talk to a caller before letting them in. It works in homes, flats and modest commercial entrances.

Can I fit it myself?
Mounting the units is straightforward, but the link between the entrance point and the handset needs wiring in. If you are not confident with that, a qualified installer can carry out the work for you.
