Comparable CCTV quotes name every camera (model, resolution, position, purpose), show the storage calculation against a stated retention, include commissioning, app setup, GDPR signage and a written warranty. The classic trap is comparing a 'supply and fit 8 cameras' one-liner against a properly specified design — the one-liner is always cheaper and usually worse everywhere it counts.
Strip any two quotes to the checklist and the gap usually explains itself: 2MP no-name cameras against 4MP ColorVu units; a 1TB drive yielding nine days against 4TB yielding thirty-five; clipped-on bell wire against contained Cat6; no commissioning line at all. Labour quality hides hardest — neat soffit routes and sealed glands take hours that bargain installs skip, and you discover the difference the first wet winter. Cheap is occasionally right (simple overview needs), but it should be a choice you make knowingly, not a discovery.
No written quote or a one-line WhatsApp price; pressure to decide today; cash-only; no business address or insurance evidence; 'we'll decide camera positions on the day'; storage unstated; warranty 'on the parts only' with no labour; and any reluctance to name equipment models (which usually means whatever's cheapest at the wholesaler that week). Conversely, a slightly dearer quote with a real schedule, real maths and a verifiable certification is the cheaper purchase over five years — it's the one that records the night it matters.
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.
