Invision Security: CCTV and alarm installation across London and Essex

Invision Security presents itself as a local company serving London and Essex, with the towns of Grays and Thurrock named in its own description of the areas it covers. Its work centres on electronic security for both residential and commercial premises: surveillance cameras, intruder detection, entry control and intercoms, plus a monitoring service that routes alarm activations to a response centre.

The company states that it has more than 15 years of experience and over 500 completed projects, and that it has served more than 500 clients across the residential, commercial and industrial sectors. It also advertises a free site survey and same-day quotations.

Surveillance, access and alarm systems

The catalogue is organised around a small number of product families, each with its own technical features:

• CCTV systems: high-definition cameras in HD and 4K, night vision, remote access and cloud storage, presented as combining remote monitoring with intelligent analytics.
• Access control: biometric scanners, smart cards and mobile access, with audit trails for tracking entries.
• Intruder alarms: systems with 24/7 monitoring, instant alerts, integration with other devices and emergency response protocols.
• Monitored alarms and police response: activations are handled by an alarm receiving centre (ARC) that notifies the customer or nominated key holders and takes the appropriate action. The company lists AI detection, facial recognition, behaviour analysis and real-time alerts among the capabilities of this line.
• Intercom systems: the site also frames this section around security assessments and consulting, including risk assessment, custom solutions, compliance review and staff training.
• Biometric security and alarm response appear as separate entries in the services menu.

How the company presents its credentials

Invision Security describes itself as SSAIB and insurance approved, and states that its staff are vetted and DBS checked. It also mentions ISO certification. Alongside these claims it cites operational figures: 99.9% system uptime, a response time of under five minutes and 100% client satisfaction. These are the company's own stated figures rather than independently verified data.

Other arguments it puts forward are the absence of hidden fees and support from the initial consultation through installation and subsequent maintenance.

Reviews and client profiles

The site displays a rating of "Excellent" based on 50 reviews published on Google, according to the review widget shown. The testimonials reproduced on the page come from a retail group CEO, a corporate tower facility manager, a property owner and a manufacturing operations director, and they refer to retail security infrastructure, access control in industrial settings and residential installations. One of the reviews visible on the page is cut off and begins with a negative experience, so the selection shown is not uniformly positive.

Technical articles and contact

The company maintains a blog with guidance content signed by Dhirender Singh, with entries on choosing a home security system, repairing alarms in Essex, the benefits of modern security systems, professional alarm installation, access control systems and intruder alarms. The articles visible at the time of writing were dated between September and October 2026.

Enquiries are handled through a form that asks for name, email, telephone, postcode and the service of interest, with the same list of six service families. The company also offers a free consultation and quote.
