CCTV Installation
Our CCTV installation service provides comprehensive security coverage using high-definition cameras and advanced monitoring technology. We design and implement customised surveillance solutions for commercial and residential properties across Yorkshire. Our systems integrate with 24/7 control room monitoring to ensure immediate response to security threats.
Professional Guarding
We offer trained SIA-licensed security personnel for on-site protection at commercial premises including banks, manufacturing facilities, and car dealerships. Our guards undergo rigorous background checks and receive ongoing training in customer service and security protocols to ensure professional conduct at all times.
Mobile Patrols
Our mobile patrol service provides cost-effective security for vacant properties and business premises across the North of England. Uniformed officers in marked vehicles conduct regular inspections while visible signage acts as a deterrent to potential intruders, with all patrols coordinated through our 24/7 control room.
Access Control
We design and install advanced access control systems that restrict unauthorised entry while allowing seamless movement for permitted personnel. Our solutions range from simple single-door systems to complex multi-facility networks with integration options for existing security infrastructure.
Alarm Response
Our 24/7 alarm response service provides immediate action for intruder and fire alarm activations. Specially trained officers respond to alerts within BS7984 compliance standards, with key holding services and centralised monitoring available to eliminate risks for lone workers.
