Celius

What Celius does

Celius Ltd is a privately held UK security systems installer incorporated in July 2007 and headquartered in Northampton, England. The company specializes in the design, sale, and professional installation of proactive CCTV security alarm systems for residential properties, commercial businesses, and construction developments across multiple English counties including Northamptonshire, London, Surrey, Hertfordshire, Buckinghamshire, Bedfordshire, Warwickshire, Lincolnshire, and Merseyside. Its core technology stack integrates HikVision IP cameras (fixed lens, vari-focal, PTZ, and ANPR variants) with Ajax Systems intruder alarm hubs, supplemented by Celius's own proprietary CEL-aD2 SiteMaster multi-function security unit, CEL-aD1 and CEL-aD1-b CCTV panic alarm systems, and CEL-iN1/CEL-iN3 remote door entry products. The portfolio also includes 3G/4G CCTV systems for locations without landline internet and IP/GSM/2-wire intercom systems.

Celius generates revenue through three primary streams: hardware sales (HikVision cameras, Ajax alarm systems, SiteMaster units, intercoms), professional installation services performed by qualified in-house Celius installers rather than subcontractors, and recurring 24/7 remote monitoring by SIA-licensed staff. Pricing is quote-based and not publicly disclosed, with sales conducted via website contact forms, phone inquiries, and on-site demonstrations using a mobile demo van. Customer segments are diversified across individual homeowners, small retail businesses, automotive dealerships, warehouses, office blocks, transportation yards, and construction sites. The company holds several UK regulatory credentials including ICO data protection registration, HikVision Authorised Partner status, Public Space CCTV Monitoring SIA Licence, and IPAF Powered Access Licence. There is no evidence of external investment, acquisitions, or institutional ownership; the firm appears to be founder/owner-operated as a regional SMB.
