A simple guide to choosing the right door-entry system for your building.
A secure entrance is an important part of protecting a home, apartment building or commercial property. A modern video intercom system allows you to see and communicate with visitors before granting access, helping you make more informed decisions about who enters your premises.
Whether you own a house in London, manage flats in Manchester or operate a commercial building in Birmingham, choosing the right intercom depends on your security requirements, entrance layout and access control needs.
This guide explains what a video intercom system is, how it works, what to consider when choosing one and why Commend video intercom systems are worth exploring for demanding security and communication environments.
What Is a Video Intercom System?

A video intercom system is an electronic communication solution that combines a camera, microphone, speaker and indoor or remote answering device. It allows occupants or security staff to see and speak to visitors at an entrance before deciding whether to grant access.
Unlike a traditional audio-only intercom, a video intercom adds visual verification to the visitor communication process. Depending on the system, users may also be able to unlock doors, manage entry points remotely or connect the intercom to wider security infrastructure.
For UK properties, video intercoms can be useful in residential developments, gated entrances, apartment blocks, offices, healthcare facilities and other buildings where controlled access is important.
How Does a Video Intercom System Work?
A typical video intercom system operates through four main stages:
- Visitor identification: A visitor presses a call button or selects a person or department on the entrance station.
- Video and audio communication: The system sends the visitor’s image and voice to an indoor monitor, reception desk, compatible phone or other authorised answering device.
- Access decision: The resident, receptionist or security operator speaks with the visitor and decides whether to allow entry.
- Door or gate release: Where supported and configured, the authorised user releases an electric lock, door or gate through the system.
Some modern IP-based systems use a building’s network to connect multiple entrance stations, answering devices and security control points. This can be particularly valuable for larger premises with several entrances or buildings.
The exact functions depend on the selected equipment, network design and installation.
What Is the Best Video Intercom System for My Home?
The best video intercom system for your home is the one that matches your property’s entrance, your preferred way of answering calls and your security requirements.
Before purchasing a system, consider these factors:
- Video quality: Choose a camera that provides a useful view of visitors in the lighting conditions around your entrance.
- Two-way audio: Clear speech helps prevent misunderstandings and makes visitor communication easier.
- Remote answering: If you want to answer the door when away from home, check whether the system supports a compatible mobile application or remote client.
- Entry control: Confirm that the system can work with your existing door lock or gate, where required.
- Weather resistance: Outdoor equipment should be suitable for the location and exposed conditions in which it will be installed.
- Installation requirements: Existing cabling, network availability, power supplies and door hardware can influence installation costs.
- Future expansion: If you plan to add entrances or connect additional security equipment, consider scalability from the outset.
A conventional residential video doorbell may be sufficient for a single front door. A larger property, apartment development or shared entrance may require a more comprehensive video intercom and access control solution.
What Is the Best Intercom System for Different UK Properties?
There is no single best intercom system for every building. The right choice depends on how many people use the entrance and how access needs to be managed.
For houses: A straightforward video door intercom may provide the essential functions needed to identify visitors and communicate before opening the door.
For flats and apartment buildings: A multi-tenant intercom can help visitors contact individual residents, while authorised personnel manage shared entrances. Directory functions and integration with access control may be important.
For offices and commercial buildings: A networked intercom can connect entrance stations with reception desks or security teams. Consider how the system will handle deliveries, visitors and restricted areas.
For larger or high-security premises: Multiple communication points, centralised monitoring, integration with other systems and dependable operation may be more important than the feature set of a typical home doorbell.
When comparing systems, assess the complete installation rather than judging products by camera specifications alone.
Why Consider Commend Video Intercom Systems?
Commend specialises in professional intercom and security communication solutions for environments where dependable communication and integration are important. Its solutions serve sectors including commercial buildings, healthcare, transport, industry and critical infrastructure.
Commend is particularly worth considering when a project requires more than a basic doorbell.
Key areas to evaluate include:
- Professional communication: Assess the audio performance and communication features required for clear conversations at entrances and operational points.
- IP-based connectivity: Depending on the selected equipment, network-based architecture can support communication across multiple locations.
- Integration possibilities: Explore how the proposed solution can connect with compatible access control, security or building systems.
- Scalability: Consider whether the system can accommodate additional stations, entrances or communication points as requirements grow.
- Application-specific hardware: Commend offers different devices and modules for various installation scenarios, allowing solutions to be specified around project needs.
For example, Commend’s OD5 and OD10 touchscreen intercom stations are designed for outdoor applications. The company also offers IP intercom modules that can be incorporated into customised communication stations and other equipment.
These options make Commend relevant to professional installations such as commercial entrances, controlled-access facilities and larger property developments.
However, the most suitable Commend configuration depends on the project. Homeowners looking for a simple residential video doorbell should confirm that the proposed solution meets their needs and budget before choosing a professional intercom platform.
Explore the manufacturer’s official Commend UK solutions to understand the available applications and discuss the right configuration with a qualified supplier or installer.
Choosing a Video Intercom System UK: What Should You Check?
Before committing to an installation, ask your supplier or installer the following questions:
- Will the system work with the building’s existing wiring, network and door-release hardware?
- Does it support the required number of residents, users and entrances?
- Can authorised users answer calls remotely if needed?
- Which access control and security integrations are supported?
- What are the installation, configuration, maintenance and ongoing service costs?
- How will user permissions, software updates and network security be managed?
For UK installations, also consider accessibility, data protection and the handling of video footage. If the system records identifiable people, the property operator should assess its obligations under applicable UK data protection law and relevant ICO guidance.
A site survey is especially useful for apartment buildings and commercial premises because it helps identify cabling constraints, entrance layouts and integration requirements before equipment is specified.

Final Thoughts: Which Video Intercom Should You Choose?
Choosing the right video intercom system starts with understanding your property, users and access requirements.
