A door intercom system offers improved access control

COR3 is here to serve your security needs; in addition to larger products such as electric doors, security bollards, gate systems and road barriers, we also specialise in audio, video and wireless intercoms. We have a wide range of intercom systems for almost every application, from simple gate and door entry through to sophisticated networked systems. An intercom system from Proton can be easily installed to existing doors and gates, offering effective and cost-efficient security and greater control over access.

A door intercom is a great way of finding out who’s paying you a visit, before you answer the door or allow your guest through any other security measures. This means that you can have complete control over who enters your property - and with modern technology allowing more flexibility, you can even choose a wireless intercom, giving you a hassle-free solution without any extensive installation requirements.

A wireless intercom system or door intercom can suit any property

Here at COR3, we like to offer our clients a variety of solutions, so that they can choose the best intercom system for their individual needs. We design and manufacture PABX units suited to large private homes and small offices, which offer all the facilities associated with PABX units such as intercom between phones, external telephone lines and seamless integration with door and gate controls.

Alternatively, a simple two wire system can be deployed to residences and small offices easily, and is a very cost effective method of voice or video access control.

Our fantastic GSM range is another type of intercom system that’s proving very popular and offers greater control over gate or door operation; it’s fully self-contained and works on the GSM mobile phone network. The system allows calls to be made from a door or gate to any telephone, anywhere in the world.
