By the DC Fire & Security engineering team — installing and maintaining fire and security systems since 2010. Updated June 2026.
An electrician can mount cameras and run cables competently; a CCTV specialist designs identification coverage, sizes storage, configures recording, analytics and remote access securely, handles GDPR setup and issues the commissioning certificate insurers ask for. For anything beyond hanging supplied hardware, specialists deliver materially different outcomes — and certificated firms (SSAIB/NSI for security systems) can be verified, not taken on faith.
Two installations can look identical on the wall and behave nothing alike when tested by events: one identifies a face at the gate at night, holds 31 days, alerts only on people, and exports a police-ready clip in two minutes; the other shows a silhouette, overwrote the incident after nine days, pings every headlight and is reachable from the open internet with admin/12345. The gap is design and configuration — the speciality. Certification matters for the same reason it does in alarms: SSAIB/NSI-certificated security firms are independently audited on exactly these practices, and your insurer recognises their paperwork (verify any firm — including us, registration 13629 — on the public registers).
Day-rate maths tempts: an electrician at £250–£350/day hanging supplied cameras can undercut a specialist quote noticeably. Like-for-like it narrows fast — specialist quotes include the design time, configuration, commissioning, documentation and warranty the day-rate excludes, and equipment supplied at trade often offsets margin. Where budgets are tight, the efficient split is the one above (sparks pull cable to our drawing); where quotes are compared, use our 10-point quote checklist so 'cheaper' is measured against the same deliverables. The reliably expensive option is the rework: paying twice because coverage, storage or security was nobody's responsibility the first time.
We install and maintain fire and security systems across Bedfordshire, Hertfordshire and London — with fixed written quotes, a 36-month warranty, and certification your insurer will accept.
