Perimeter Detection Systems
ISG deploy Redwall technology, which uses a patented optical system to deliver high quality perimeter detection images with a range of 100 metres.
CCTV Surveillance Systems

Door Entry Systems
A simple yet effective deterrent against unauthorised entry, vandalism and anti-social behaviour, Interphone Security Group offers an extensive range of Door Entry systems & solutions.
CCTV Surveillance Systems
Multifunctional, 360° rotating cameras, light-sensitive lenses and colour/mono switching all combine to create a powerful CCTV security resource, day and night.
Automatic Gates & Turnstiles
Automatic gates & physical barriers can play an important role in residential security. For this reason, automatic gates are also a core product range offered by ISG.
DTT-ready Aerial Installations
One in five people in the UK watches television through a communal aerial, and Interphone Security Group offers a complete service for developers, landlords and managing agents. We will guide you to a cost-effective, future-proof solution that receives all the existing analogue channels, digital radio broadcasts (DAB) and Freeview now, but which is fully compliant for when Switchover to full DTT takes place.
Communal Satellite Installations
One in five people in the UK watches television through a communal aerial and Interphone Security Group offers a complete communal satellite installation service for developers, landlords and managing agents. We will guide you to a cost-effective, future-proof communal satellite installation solution that receives all the existing analogue channels, digital radio broadcasts (DAB) and Freeview now, but which is fully compliant for when Switchover to full DTT takes place.
Specialist Technologies
In addition to our Commercial Residential and Business Security product ranges, ISG offers advanced security solutions for specialist applications. These are designed for areas where in-depth, sophisticated security is required; for example, a restricted zone where every person entering must be authorised and verified.
Maintenance & Support
We think the most telling test of a supplier or partner comes after the sale: when you need support. By their very nature, security systems aren’t nice-to-haves – they’re an essential part of the infrastructure of your business. That’s why we have an extensive team of engineers out on the road, tracked by GPS, and with ready access to the architecture and detail of your system.
