Services
Intruder Alarms
We design and install intruder alarm systems using passive infra-red detectors, microwave sensors, and magnetic contacts. Systems provide 24/7 protection for occupied or empty properties, with optional dual-path communication to alarm receiving centres. Our NSI Gold-accredited installations meet EN50131 standards, ensuring reliable detection and police response compatibility.
Access Control
Custom access control systems regulate building entry using proximity fobs, biometric readers, or integrated software. We configure systems for single-door setups or enterprise-wide networks, with features like fire roll-call tracking and staff time-sheet integration. All installations comply with NSI NCP 109 standards for commercial security.
CCTV Cameras
High-definition CCTV systems with fixed, PTZ, and infrared cameras protect domestic and commercial properties. We offer remote monitoring via smartphones and integration with alarm receiving centres. Installations meet NSI NCP 104 standards, including storage solutions for live/recorded footage and scalable multi-monitor setups.
Fire Alarms
Comprehensive fire alarm systems for commercial buildings, including addressable and radio-controlled options. We conduct risk assessments and install BS-compliant systems with maintenance contracts available. Solutions cover simple two-wire setups to complex systems requiring asbestos-compliant installations.
Fogging Devices
Bandit UK fogging systems deliver 28m/s fog density within 0.1 seconds to deter intruders. These residue-free devices integrate with existing security systems, providing visual obstruction while alarms activate. Ideal for high-risk commercial properties requiring immediate intruder deterrence.
