At a Glance
Key Benefits of 2-Wire Intercoms
Cost-effective, quick to install, and built for modern living.
Cost effective upgrades
Reuse existing wiring to save time and money.
Minimal disruption
Fast installation with no invasive rewiring.
Video and audio
Upgrade from audio only to full video entry.
Scalable
From single entry apartments to high rise complexes.
Integration
Connect with CCTV and access control for a complete solution.
Compatibility and cabling
Most buildings have a mix of cabling, from older 4 or 6 core telephone cable through to Cat5. We confirm what you have and design to suit. Where the existing copper is in good condition, 2-wire systems can carry video and power on the same pair, so you can upgrade without running new riser cables.
Run length guidance
On good copper, 2-wire video intercoms typically run reliably up to about 100 metres per line. Longer distances or tired conductors may need mid span power or a different design approach. We verify this during the site survey.
Mobile app calling
Many 2-wire platforms support off-site answering through a mobile app. Where supported, we set up push notifications, call groups and time schedules so residents and building managers can answer from their phones.
Integration options
Tie entry points to access control for managed door release and lift control. Integrate with CCTV so calls and door releases are tagged on video for easy review. Where remote administration is needed, we can include a small 2-wire to IP gateway.
