You’ve secured your building and kept the intruders out, but how do you let visitors in? This is the job of an intercom system. Providing the convenience of a doorbell but with the added security of allowing you to screen visitors before granting or denying them access into your building. An intercom system can be integrated with an access control system to control entrance doors, boom gates and roller doors. And monitored and controlled from a single handset in a reception, to hundreds of handsets in an apartment building.

At Red Flag Systems we’ve partnered with some of the best intercom suppliers in the security industry to provide our customers with a range of reliable and high-quality intercom systems. From upgrading out-dated systems in high-rise apartment buildings, or installing multi-entrance intercoms for industrial sites, we have the expertise to ensure the smooth flow of visitors into your site.

Smart Technology

Whether you’re an operations manager out in the warehouse waiting for stock to arrive or you’re a resident in an apartment building waiting for Uber Eats, missing a delivery can be frustrating.

With intercom smartphone technology you can receive calls directly to your mobile phone no matter where you are.

Not only allowing you to speak to and see the visitor but granting them access in with a press of a button.

Flexible Applications

High-rise apartment block, office building, warehouse or industrial plant. No matter what sort of site or building you occupy, if you expect visitors and don’t want them freely wandering in to see you, you’re going to need an intercom system.

At Red Flag System we supply and install a wide range of intercoms to suit almost any application; solar-powered intercoms with SIM cards for remote gates, IP-based intercoms with smartphone technology for modern apartment buildings, or VOIP intercoms to integrate with the existing phone system in your office.

We have a range of flexible intercoms to suit your requirements.
