Brentwood has a particular problem. The Elizabeth line makes it one of the fastest commuter routes into London, which means that by 08:30 on any given weekday, a significant portion of the town’s business-owning population is on a train heading for Paddington or Liverpool Street. Back at the warehouse on London Brentwood Commercial Park, the deliveries keep arriving. Contractors turn up at Childerditch Industrial Park. Haulage drivers need to drop off and collect at units that have nobody standing at the door to verify them. What happens to site security when you are not there to answer the door? The question of who is on your site – and whether they should be – does not pause because you are travelling.
That gap is precisely what a well-specified intercom and door entry system closes. We are Eastern Security, a local, family-run security company that cares about your security. Based in Southend-on-Sea, Essex, we install Door Entry Systems across the whole of Essex (and parts of London) – including Brentwood’s commercial parks, business parks, retail units and residential blocks. If the right people are not getting in and the wrong people are, we can address that. And we can set it up so you can manage it from your phone, whether you are on-site or 45 minutes down the Elizabeth line.
Who Needs Door Entry in Brentwood?
The primary buyer is the business owner or facilities manager who knows that access verification is an operational problem, not just a security one. If you run a logistics or warehouse unit at London Brentwood Commercial Park or Childerditch, your day involves a revolving door of delivery drivers, contractors, subcontractors and agency staff. None of them can be left to self-verify. A video door entry system with remote mobile authorisation means you see who is at the gate, speak to them, and grant or deny access from wherever you are. Every event is logged. Every access decision is yours.
The secondary buyer is the landlord or block manager. If you manage purpose-built blocks or HMOs in Brentwood, you carry a compliance burden that makes uncontrolled communal entry a specific operational liability. Every tenancy change raises the question of who still holds credentials – and with a proximity fob system, the answer is a two-minute deactivation job rather than a locksmith visit and a full re-key. Does any of this sound familiar? We work with both buyer types regularly. The system is different; the principle – you control who enters – is the same.
Brentwood’s Commercial Landscape
Brentwood’s position at the A127/A128 junction, very close to the M25, has made it a genuine distribution hub. London Brentwood Commercial Park and Childerditch Industrial Park – a 32-acre established business community with storage yards and warehouse units – generate continuous contractor and haulage traffic across shift patterns that run well outside normal office hours. Early morning deliveries, late collections, weekend access for agency staff: these are not edge cases at Childerditch. They are the operational baseline. A door entry system that logs every access event with a timestamp gives any logistics or warehouse operator a verifiable record of who was on-site and when – which matters both for internal accountability and for any insurance or police interaction following a commercial theft or vehicle crime incident.
Warley Hill Business Park presents a different configuration: a multi-tenant office and light industrial community where shared access points require credential management across businesses that may have no operational relationship with each other. An audio intercom with access control integration can separate tenant access cleanly without the cost and disruption of full video entry at every door.
The High Street retail corridor has its own exposure. Shoplifting accounted for 43 reports in Brentwood in March 2026 alone – one in five of all commercial crimes recorded – according to police.uk data (retrieved June 2026). Its defining characteristic is repeated, planned access by individuals who have identified weaknesses in advance. A door entry system at the staff entrance – coded separately from the public-facing shop floor – stops retail theft from escalating into a back-of-house intrusion. Hardware handles that boundary. Not staff vigilance.
The Crime Context
Around 1 in 12 business premises in England and Wales experienced burglary or an attempted break-in in the past year, according to the Home Office Commercial Victimisation Survey 2023 – making it the second most common crime against businesses after theft. In Brentwood specifically, around 300 burglaries were recorded in the past year across all property types – roughly 25 a month – according to police.uk data (retrieved June 2026). Essex as a county recorded approximately 5,200 burglaries in 2025, a decrease of nearly 17% year-on-year and below the national average, according to Essex Police data via data.police.uk (retrieved June 2026). A well-secured premises, in that context, sits in a materially better position than the county average implies.
For Brentwood’s industrial and logistics operators, the commercial vehicle crime profile is the sharper concern. Units at London Brentwood Commercial Park and Childerditch run continuously, and haulage movements mean that unfamiliar vehicles and personnel are a daily feature of operations. Without a door entry system, the practical result is either a propped-open door or a waved-through culture. Neither is defensible on an insurance claim. Neither leaves a log.
Door Entry Systems and Intercom Installation in Brentwood
We have over 25 years’ experience in security system design and installation, and the right system depends entirely on your premises, your operational pattern and who needs to be kept out. We do a site survey before we recommend anything. That is not a sales technique. It is the only way to specify a system that actually works for your building.
Video door entry with remote mobile authorisation is the lead system for Brentwood’s logistics and industrial operators. A caller presses the panel at the gate or entrance; you receive an alert on your phone, see live video, and open the door remotely – whether you are at your desk, in a meeting or on a platform at Liverpool Street. Access is logged by default. Nearly 4 in 10 organisations now use mobile credentials for access control, with contactless entry cited as the leading trend in the sector by almost half of industry professionals surveyed, in a global survey of over 1,200 access control professionals by HID Global and IFSEC Insider, 2024. For Brentwood’s distribution-hub operations, this is not a trend – it is the operational answer to the commuter-drain unmanned-premises problem.
Proximity fob and proximity reader systems suit Brentwood’s purpose-built residential blocks and HMO stock. A proximity reader (a contactless device; the fob or card is held near it, not inserted) at the communal entrance manages credential-based access cleanly. When a tenancy ends, the credential is deactivated in minutes – no locksmith, no re-key, no period of uncertainty about who still holds a physical key. For a block manager running multiple Brentwood properties, that operational simplicity compounds across the portfolio.
Audio intercom with access control integration covers Warley Hill Business Park multi-tenant configurations and High Street retail and mixed-use units, where video is not required, but controlled staff entry to back-of-house areas must be hardware-enforced. We can integrate door entry with your existing intruder alarm system – and where CCTV is already installed, we can connect the two so that a door entry event triggers a camera view.
On all commercial installations, we specify fail-safe electronic locks as standard on any door that forms part of an escape route. This is not optional – see the legislation section below.

Legislation You Should Know
This is an informational overview – your fire risk assessment and a competent fire safety professional should determine your exact obligations for your premises.
Regulatory Reform (Fire Safety) Order 2005, Article 14 creates a legal requirement that electronically locked doors on escape routes in communal areas can be easily and immediately opened in an emergency. In practice, any electronically controlled entry on a communal escape route must be specified fail-safe, capable of releasing on fire alarm activation to meet this obligation. This applies directly to Brentwood’s block managers and landlords operating purpose-built blocks and HMOs. We specify fail-safe door releases at the survey stage. Fire interface testing – confirming the connection between the door release and the fire alarm panel – sits within Blake Fire and Security Systems’ scope as our dedicated fire safety partner. We coordinate between both disciplines so nothing falls between the two.
Equality Act 2010, Section 20 places a legal duty on service providers and employers to make reasonable adjustments where a physical feature creates a substantial disadvantage for disabled persons. For Brentwood’s retail-strip and commercial-park operators, that means accessible call points, appropriate door-opening forces (no more than 30N under Approved Document M guidance) and non-key alternatives must be factored into any new door entry specification. We carry this into the survey conversation – it is a design consideration, not an afterthought.
UK GDPR applies to every video door entry system that captures footage of identifiable individuals – which means virtually all of them. Under Article 4(1), video footage of a person is personal data. You need a lawful basis under Article 6 (typically legitimate interests for business premises security), appropriate signage at the entry point, and a process for handling Subject Access Requests within one calendar month. There is no statutory requirement for a specific retention period – the right period depends on your documented policy and the storage limitation principle. We flag the data protection obligations at the survey stage; your data controller determines the policy.

Frequently Asked Questions
What types of door entry system can Eastern Security install?
We install audio intercoms, video door entry systems with remote mobile app access, and proximity fob and reader systems for multi-occupancy buildings. On commercial premises, we can integrate door entry with existing intruder alarm and CCTV systems. The right system for your premises depends on the number of entry points, your access management requirements and whether you need remote authorisation capability. Contact us on 01702 467850 for a free, no-obligation site survey, and we will specify the right solution for your building.
Is Eastern Security qualified to install door entry systems?
Yes. We are SSAIB-approved for intruder alarm systems and CCTV. The same experienced engineering team carries out our door entry installations. Our engineers are DBS-checked and carry out site surveys before specifying any system. Eastern Security is a local, family-run security company that cares about your security, with over 25 years of experience across Essex.
How often should a door entry system be serviced?
We recommend annual maintenance for door entry systems, which includes checking all panel functions, testing the door release mechanism and reviewing access credentials. We offer responsive maintenance teams and can arrange annual servicing contracts. Call 01702 467850 to discuss a maintenance plan.
Can a door entry system be connected to our existing CCTV at a warehouse or industrial unit?
Yes – integration between door entry and CCTV is a standard part of what we design for industrial and logistics premises. A door entry event can trigger a camera view, and the access log from the door entry system can be cross-referenced with footage timestamps. For warehouse and commercial park operators at London Brentwood Commercial Park and Childerditch, this gives you a joined-up record of who entered and what happened around that access event. We assess the integration options at the site survey stage, based on your existing camera setup and network infrastructure.
What happens to the electronic door lock if the fire alarm activates?
On any door forming part of an escape route, the electronic lock must be specified fail-safe – meaning it releases automatically when the fire alarm activates, so the door can be opened without any powered or manual intervention. This is the practical requirement that flows from Article 14 of the Regulatory Reform (Fire Safety) Order 2005, which requires that emergency doors are not locked in a way that prevents easy and immediate use in an emergency. We specify fail-safe door releases as standard on escape routes at the survey stage. The actual fire interface connection – confirming the door release is correctly wired to your fire alarm panel – is within the scope of our dedicated fire safety partner, Blake Fire and Security Systems. We coordinate both disciplines so the installation meets your obligations. Contact us on 01702 467850 to discuss your premises.
Can I control who has access and see an access log remotely when I’m not on site?
Yes. Video door entry systems with mobile app integration let you see, speak to and admit or deny callers from your phone, wherever you are. Proximity fob and access control systems can be managed remotely to add, modify or deactivate credentials without attending the premises, which is particularly useful for landlords and block managers covering multiple Brentwood properties. Access logs are generated automatically by the system, recording who entered, when, and by which credential. For business owners who are regularly off-site during peak access hours – which, in a commuter town like Brentwood, means most of the working day – remote management is not a luxury. It is how a properly specified system works. Call us on 01702 467850 or contact us via the form below to arrange a free, no-obligation site survey.
