Door Entry Systems

Communicating with a visitor is crucial for identifying whether they should be permitted entry onto your premises. With audio and video capabilities, the door entry phone systems installed by  A.T. Alarms allow you to take control.

Our door entry systems range from simple audio devices to advanced video systems. The entry phones are available with 1-50 call buttons or with a digital keypad and LCD display. We even offer entry door systems that connect across multiple premises.

If you’re regularly on the move, our GSM mobile phone entry systems connect to your smartphone, so you’ll always be able to take that call. 

We will carry out an in-depth survey of your premises and identify which systems will be most suitable for your business. All of our equipment is handpicked from the world’s leading manufacturers, so you’re guaranteed to receive a door entry system with the latest security features. As an NSI-Gold accredited company, you can trust A.T. Alarms to provide the highest levels of service. We are based in Nottingham but serve the UK.
