Controlling who enters your property is one of the most important aspects of modern security. Whether you manage an office, apartment block, warehouse, school or commercial building, allowing unrestricted access can expose your premises to theft, vandalism and unauthorised visitors.
Video door entry systems provide a smarter and more secure way to manage access. Instead of opening the door without knowing who is outside, you can see visitors in real time, speak with them and decide whether to grant or deny entry. Modern systems combine high-definition video, two-way audio, remote access and smart integration with access control technology to create a safer environment for employees, residents and visitors.
As businesses and residential properties increasingly adopt intelligent security solutions, video door entry systems have become a popular choice across the UK. They improve convenience while significantly reducing security risks.
In this comprehensive guide, we'll explain how video door entry systems work, the different types available, their key benefits and how to choose the right solution for your property in 2026.

What Is a Video Door Entry System?
A video door entry system is an electronic access control solution that allows you to see, speak to and verify visitors before granting them access to your property. Unlike traditional doorbells or audio intercoms, these systems include a camera at the entrance and an indoor monitor or mobile application that displays live video when someone presses the call button.
This additional layer of visual verification helps prevent unauthorised access while improving convenience for both residential and commercial properties.
Modern video door entry systems can also integrate with CCTV, access control systems, smart locks and mobile devices, allowing users to manage entry from almost anywhere.
Main Components of a Video Door Entry System
- Outdoor video door station with HD camera.
- Call button with two-way audio.
- Indoor monitor or touchscreen display.
- Electronic door release mechanism.
- Power supply and controller.
- Mobile app for remote access (on compatible systems).
How Does a Video Door Entry System Work?
The operation of a video door entry system is simple yet highly effective. When a visitor arrives and presses the call button, the outdoor unit activates the camera and sends a live video feed to the indoor monitor or authorised mobile device.
The property owner, receptionist or security team can then:
- See who is at the entrance.
- Speak with the visitor using two-way audio.
- Verify the visitor's identity.
- Unlock the door remotely if access is approved.
- Ignore or reject unknown visitors.
Many modern systems also allow call forwarding to smartphones, enabling users to answer the door even when they are away from the property.
Typical Visitor Journey
- Visitor presses the door station call button.
- The indoor monitor or mobile app receives the call.
- Live video and audio are activated.
- The user verifies the visitor.
- Access is granted or denied remotely.
- Entry activity can be logged for future reference.
Types of Video Door Entry Systems
Different properties require different types of video entry solutions. Choosing the right system depends on the size of the building, the number of users and the level of security required.
1. Audio & Video Door Entry Systems
These systems combine two-way audio with live video, allowing users to identify visitors before opening the door. They are commonly used in offices, homes and small commercial premises.
2. IP Video Door Entry Systems
Internet Protocol (IP) systems connect to your network, enabling remote management through smartphones, tablets or desktop computers. They are ideal for businesses that require flexible access control.
Designed for apartment buildings and residential developments, these systems allow multiple residents to receive calls independently while sharing a common entrance panel.
4. Wireless Video Door Entry Systems
Wireless systems reduce installation complexity by using Wi-Fi or other wireless communication methods. They are often suitable for smaller properties and retrofit projects.
5. Integrated Access Control Systems
Many businesses choose integrated solutions that combine video entry, access control, CCTV surveillance and electronic locking into a single security platform.
Key Benefits of Video Door Entry Systems
Video door entry systems provide far more than visitor convenience. They strengthen building security, improve operational efficiency and create a better experience for employees, residents and guests.
1. Enhanced Security
Being able to visually verify visitors before unlocking the door significantly reduces the risk of unauthorised access, tailgating and opportunistic crime.
2. Two-Way Communication
Built-in microphones and speakers allow clear communication with visitors before granting access, helping staff or residents make informed decisions.
3. Remote Door Control
Many systems allow authorised users to unlock doors remotely through an indoor monitor or secure mobile application.
4. Improved Visitor Management
Reception staff can verify visitors quickly, reducing waiting times while maintaining better control over who enters the building.
5. Integration with Other Security Systems
Modern video door entry systems can integrate with CCTV cameras, access control, intruder alarms and smart building management systems to provide a complete security solution.
6. Better Safety for Employees and Residents
Whether installed in an office, apartment building or commercial property, video verification helps create a safer environment by ensuring only authorised individuals gain access.
Where Can Video Door Entry Systems Be Used?
Video door entry systems are highly versatile and suitable for a wide range of residential, commercial and public sector properties. Whether you need to control access to a single office entrance or manage hundreds of residents in an apartment complex, these systems provide a secure and convenient solution.
Below are some of the most common applications across the UK.
1. Office Buildings
Modern offices receive a constant flow of employees, clients, contractors and delivery drivers. Without an effective visitor management process, unauthorised individuals can easily gain access to sensitive workspaces.
A video door entry system enables reception staff or office managers to identify visitors before unlocking the entrance, reducing security risks while maintaining a professional welcome.
Benefits for Offices
- Verify visitors before granting access.
- Reduce unauthorised entry.
- Integrate with office access control systems.
- Improve visitor management.
- Protect confidential business areas.
- Support hybrid and remote working environments.
2. Flats & Apartment Buildings
Multi-occupancy residential buildings require secure access while ensuring convenience for residents. Video door entry systems allow occupants to see and speak with visitors before opening the main entrance, improving safety without requiring them to leave their flat.
Many modern systems also support smartphone access, enabling residents to answer calls remotely even when they are away from home.
Benefits for Apartment Blocks
- Increase resident safety.
- Reduce unwanted visitors.
- Manage deliveries more efficiently.
- Support multiple apartments from one entrance panel.
- Provide convenient remote access.
3. Commercial Buildings
