Security Systems Installer in West Sussex
Professional CCTV, access control and intruder alarm installation for homes and businesses across West Sussex and the South East. One accredited team. Systems designed around your property, not sold from a brochure.
CCTV, access control and intruder alarms
Every security system we install is designed around the specific property and its requirements. We do not apply a standard package. Where multiple systems are needed, we design them to work together.
CCTV Installation
Hikvision HD camera systems with AI-powered AcuSense detection, ColorVu full-colour night vision and remote smartphone monitoring. Designed around your property — residential, commercial or public sector. Wired IP systems with local NVR recording.
Intruder Alarm Systems
Pyronix wireless alarm systems with PyronixCloud remote monitoring, smartphone alerts and pet-friendly sensors. Scalable from single-property domestic systems to multi-site commercial installations.
Access Control
Paxton door entry, keyless access and smart lock systems for offices, commercial buildings and residential developments. Full audit trail, time-based access rules and remote user management. Video door entry with intercom integration.
Why choose a professional security installer
Security systems that are designed and installed correctly perform reliably and produce usable evidence when needed. Camera positioning, cabling quality, NVR configuration and network setup all determine whether your system is genuinely effective or simply a box on a wall.
As a CAI+ member and NICEIC Approved Contractor, Omni3 designs and installs security systems to recognised professional standards. This matters for insurance purposes, for the evidential quality of footage, and for the ongoing reliability of access-controlled doors.
We install and maintain the systems we supply. You have a single point of contact for any servicing, upgrade or fault — not a call centre for a brand you bought retail.
Survey-led design
Every system starts with a site visit. Camera positions, access points, cable routes and recording requirements are assessed before any equipment is specified.
Single contractor
CCTV, access control and alarms can all be designed and installed by the same team — systems that are built to work together from the start.
Qualified and accredited
Omni3 is a CAI+ member and NICEIC Approved Contractor. Paxton access control systems are installed as a Paxton Gold Partner.
Ongoing support
Omni3 can provide ongoing maintenance and servicing for security systems we have installed — the same team that designed and commissioned them.
Commercial CCTV — Warehouse & Yard, West Sussex
Multi-camera wired CCTV system replacing a failed analogue installation. Full perimeter and interior coverage, NVR with 30-day recording, remote viewing via app. Installed over two days with cabling pre-run for future expansion.
Systems designed to work together
CCTV, access control and alarm systems are more effective when they are integrated. Access events can be linked to camera footage. Alarm triggers can initiate CCTV recording and push notifications. Controlled doors can release automatically on fire alarm activation.
As a multi-discipline contractor, Omni3 handles the electrical infrastructure, cabling containment and system integration under one programme — removing the coordination overhead of multiple specialist contractors.
