Why CITS Infrastructure

The credentials
that matter.

NSI-approved for CCTV and access control installations to NCP 104 standard. Police-preferred specification for monitored systems.
Full Documentation
Every installation is accompanied by as-built drawings, test certificates, equipment datasheets, and a comprehensive handover pack — essential for insurance, audits, and future engineers.

Complete Building Technology

One contractor for
your entire site.

Managing multiple contractors for CCTV, fire, cabling, and AV creates accountability gaps and delays. CITS delivers everything under one contract, one project manager, and one ongoing support relationship. Simpler for your building manager, better for your budget, and clearer when things need fixing.
