Qolsys Burglar Alarms
Qolsys IQ4 systems use military-grade PowerG technology with 128-bit encryption and dual communication paths via WiFi and SIM. These wireless systems support integration with cameras, doorbells, and home automation through the Alarm.com app. Ideal for homes and businesses requiring future-proof security unaffected by BTs PSTN switch-off.
ADC WiFi Cameras
Alarm.com WiFi cameras offer 24/7 recording with motion detection, perimeter guard analytics, and two-way audio. They operate independently of PSTN networks, ensuring uninterrupted functionality post-2025. Features include LED warnings, remote access via smartphone, and seamless integration with other smart security devices for comprehensive property protection.
Gate Automation
Installation of NICE and CAME gate systems for enhanced security and convenience. Solutions include swing and sliding gates with underground or surface-mounted motors. Systems can integrate with intercoms and access control for remote operation via smartphone apps, improving property access management while maintaining aesthetic appeal.
Access Control
Paxton-manufactured systems using proximity fobs and PIN keypads to manage entry points. Commercial solutions allow time-based door restrictions and user-specific access permissions. Reduces key replacement costs while providing audit trails and remote management capabilities for multi-site operations or high-security environments.
Wellness Solutions
Smart sensors for elderly care or assisted living, including fall detection pendants and activity monitoring. Systems track unusual patterns, night-time movements, and medication access.
