CCTV
High-definition CCTV systems to protect your business inside and out. Monitor live footage, access recordings, and deter theft or liability claims with clear, reliable coverage.
Intruder Alarms
Smart alarms that trigger instantly when doors, windows, or movement zones are breached. Get instant alerts and integrate with monitoring for rapid response.
Video Intercoms
Screen visitors, deliveries, or staff from anywhere with video intercoms. Link entry points to your phone or desktop for clear, two-way communication and remote unlocking.
Security Automation & Integration
Unify your alarms, cameras, access control, and lighting into a single smart system. Manage everything from one dashboard, on-site or remotely.
Remote Site CCTV
Keep eyes on warehouses, construction sites, or off-grid locations - anytime, anywhere. Solar-powered and 4G/5G-enabled cameras provide real-time visibility without the need for fixed internet.
Access Control
Secure your business with card readers, keypads, or mobile entry. Control who comes and goes, restrict sensitive areas, and track access logs in real time.
Permimeter Security
Protect external boundaries with motion beams, sensors, and wide-angle surveillance. Ideal for yards, car parks, and loading docks - deterrence starts before they get to the door.
Networking
Lock down your digital infrastructure. We secure business networks with strong firewalls, isolated networks for security, and physical protection for your servers and data racks.
