The result is straightforward: controlled access, reduced risk, and total peace of mind.

Comprehensive Door Entry Systems for Every Sector

Different environments demand different levels of access control. Our approach is never one-size-fits-all. We assess your operational requirements, risk profile, and compliance obligations before recommending the most appropriate solution.

Bespoke Solutions for Industrial and Logistics Hubs

Industrial and logistics environments require robust, scalable door entry systems capable of handling high traffic volumes while maintaining strict access control.

We design systems that:

• Control staff and visitor entry points

• Restrict access to sensitive operational zones

• Integrate with perimeter security and intruder alarms

• Withstand demanding environmental conditions

For warehouses and distribution centres, controlled access reduces theft risk and improves operational accountability.

Reliable Entry Management for Education and Healthcare

Schools, colleges, and healthcare facilities require secure but practical access management. Visitor identification, safeguarding protocols, and emergency compliance are critical.

Our door entry systems support:

• Controlled visitor access

• Safeguarding compliance

• Integration with lockdown procedures

• Clear audit trails of entry activity

Security must not hinder daily operations — it must support them seamlessly.

Protecting Heritage Sites and Sensitive Public Sector Buildings

Heritage and public sector buildings often require discreet solutions that preserve architectural integrity while enhancing security.

We install systems that balance:

• Visual sensitivity

• Compliance with fire and safety regulations

• Modern access control capability

• Long-term reliability

Our engineers work carefully within listed or historic buildings to ensure minimal disruption.

Integrated Technology: Video, Keypad, and Lock Release Options

Modern door entry systems offer multiple technologies designed to suit different operational requirements. Brunel Security advises on the most effective configuration for your premises.

Video Door Entry System with Lock Release

A video door entry system with lock release allows occupants to visually verify visitors before granting access remotely. These systems combine high-definition cameras, secure communication panels, and electronic locking mechanisms.

Enhanced Visual Verification and Remote Access Control

Video door entry systems provide:

• Clear visual identification of visitors

• Remote door release functionality

• Secure communication between visitor and occupant

• Recording capability where required

They are particularly suited to office buildings, multi-occupancy properties, healthcare facilities, and education environments where visitor management is essential.

Secure Keypad Door Entry System

A keypad door entry system controls access via secure PIN codes. These systems are widely used in staff-only areas or where quick, managed access is required.

Scalable Intruder Prevention for High-Traffic Areas

A door entry system with keypad offers:

• Controlled access without physical keys

• Easy code management and updates

• Audit capability when integrated with access control

• Reduced risk of lost keys compromising security

For higher-risk environments, keypad systems can be combined with proximity cards or biometric authentication for layered protection.

Audio Intercom and Door Entry Systems

For sites where video functionality is not required, audio intercom systems provide reliable communication and remote lock release capability.

Audio systems offer:

• Simple, cost-effective access control

• Clear communication between visitor and occupant

• Integration with electronic locking mechanisms

These systems remain popular for industrial units, smaller commercial premises, and gated access points.

Why Choose Brunel Security for Your Door Entry Needs?

Choosing the right provider is as important as selecting the right technology. Door entry systems must be reliable, compliant, and professionally supported.

Over 30 Years of Industry-Leading Expertise

With more than three decades of experience in security and fire systems, Brunel Security understands how access control interacts with broader safety requirements.

We design systems that work in real-world conditions — not just on paper.

NSI Gold Standard Accreditation and Compliance

Our NSI Gold accreditation demonstrates adherence to strict industry standards for design, installation, and ongoing maintenance. This provides reassurance to insurers, regulators, and procurement teams alike.

Nationwide Reach with a Specialist, Client-Centred Focus

We provide nationwide coverage while maintaining a responsive, personalised service. Every door entry system is designed around your operational needs, not limited to a single manufacturer or rigid specification.

Seamless Integration with Fire Safety and Security Systems

Door entry systems must work in harmony with wider building safety infrastructure.

Combining Access Control with Fire Life Safety

In the event of a fire alarm activation, access-controlled doors must fail-safe to allow safe evacuation. Brunel Security ensures door entry systems integrate correctly with fire detection systems to meet life safety regulations.

Integration supports:

• Automatic door release during fire activation

• Compliance with emergency egress requirements

• Coordinated safety response across systems

Security should never compromise evacuation safety.

24/7 Monitoring via Our Certified Alarm Receiving Centre (ARC)

For enhanced protection, door entry systems can be connected to our NSI Gold accredited Alarm Receiving Centre (ARC). This allows:

• Real-time alerts for forced entry attempts

• Immediate response to system faults

• Out-of-hours monitoring for unmanned sites

Continuous oversight ensures your system remains operational and effective around the clock.
