Protecting What Matters Most
Expert CCTV installation, WiFi systems, gate automation, and construction site security. Trusted by homes and businesses across Belfast and Northern Ireland.
Comprehensive Security Solutions
From residential properties to large commercial premises, we deliver professional security installations tailored to your specific requirements.
CCTV Installation
State-of-the-art CCTV systems designed for complete property surveillance. From HD and 4K cameras with crystal-clear night vision to intelligent motion detection and remote viewing capabilities, we install systems that keep you connected to your property 24/7.
Whether you need a simple two-camera residential setup or a comprehensive multi-camera commercial system, Coast Data Security delivers tailored CCTV solutions. Our installations include professional cable management, optimised camera positioning for maximum coverage, and full system configuration so you can monitor your property from your smartphone, tablet, or computer anywhere in the world. We work with leading brands including Hikvision, Dahua, and Uniview to ensure reliability and performance.
WiFi Installation
Reliable, high-speed WiFi coverage for homes and businesses. We design and install enterprise-grade wireless networks that eliminate dead zones and provide seamless connectivity throughout your entire property.
Poor WiFi can cripple a modern home or business. Our WiFi installation service begins with a thorough site survey to identify coverage challenges and design the optimal network layout. We install commercial-grade access points, run structured data cabling where needed, and configure your network for maximum security and performance. From small residential installations to large commercial premises, we deliver WiFi networks that work flawlessly.
Gate Automation
Enhance your property's security and convenience with automated gate systems. We install, maintain, and repair electric gates for residential driveways and commercial entrances, providing controlled access with style.
Automated gates are one of the most effective ways to control access to your property while adding a professional, modern appearance. We supply and install a wide range of gate automation systems including sliding gates, swing gates, and barrier systems. Every installation includes safety sensors to prevent accidents, and we can integrate your gate with intercom systems, CCTV, and access control for a complete entrance security solution.
Construction Site Security
Protect your construction site from theft, vandalism, and unauthorised access with our specialist security solutions. We provide rapidly deployable CCTV, alarm systems, and access control designed specifically for the demands of construction environments.
Construction sites face unique security challenges including expensive equipment, materials, and the constantly changing layout of the site. Our construction site security solutions are designed to be deployed quickly and moved as the site evolves. We offer solar-powered CCTV towers that require no mains power, 24/7 remote monitoring, and temporary alarm systems that can be installed and relocated with minimal disruption to your project timeline.
