Video intercom systems start from £500. Multi-unit systems for blocks of flats are priced per unit — typically £150–£300 per flat depending on the system type. We provide fixed quotes after a free site assessment." } }, { "@type": "Question", "name": "What's the difference between audio and video intercoms?", "acceptedAnswer": { "@type": "Answer", "text": "Audio intercoms allow you to hear and speak to visitors. Video intercoms add a built-in camera so you can see who's at the door before granting access. Video systems provide significantly better security, especially for properties with no line-of-sight to the front door." } }, { "@type": "Question", "name": "Can I answer the intercom from my phone?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. IP-based and smart intercom systems allow you to answer calls, see video, and release the door lock from your smartphone — anywhere with internet access. This is ideal for letting in deliveries or visitors when you're away from home." } }, { "@type": "Question", "name": "How long does installation take?", "acceptedAnswer": { "@type": "Answer", "text": "A single-dwelling intercom is typically installed within 3–4 hours. Multi-unit systems for blocks of flats usually take 1–2 days depending on the number of units and existing wiring. We schedule installation within 3–5 working days." } }, { "@type": "Question", "name": "Can you install a system for a block of flats?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. We specialise in multi-unit door entry systems for blocks of flats, HMOs, and mixed-use buildings. Each unit gets its own calling button on the external panel and an internal handset or monitor. Fob access can be configured for communal doors." } }, { "@type": "Question", "name": "What type of lock mechanism do you install?", "acceptedAnswer": { "@type": "Answer", "text": "We install electric strikes, magnetic locks (maglocks), and electric drop bolts depending on the door type and security requirements. All locks are fail-safe or fail-secure depending on fire safety and building regulations." } }, { "@type": "Question", "name": "Can a door entry system integrate with CCTV?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. Video intercom systems can integrate with your existing CCTV, recording footage of every visitor at your front door. This provides an additional layer of evidence and monitoring." } }, { "@type": "Question", "name": "What happens during a power cut?", "acceptedAnswer": { "@type": "Answer", "text": "Most electric lock mechanisms default to a fail-safe position during power cuts, allowing the door to be opened manually.

Whether it's a single front door with a video intercom or a multi-floor block of flats with fob access and individual unit calling, the principle is the same: verify first, then grant or deny entry. Read our [complete guide to door entry systems for flats](/blog/door-entry-systems-guide-flats-apartments). Eagle All Security installs audio intercoms, video intercoms, and smart access control systems for houses, flats, HMOs, offices, and [commercial premises](/services/commercial-security) across London and the Home Counties. Every system is designed around your building's layout, occupancy, and security requirements. Modern systems connect to your smartphone, allowing you to see visitors, speak to them, and release the door remotely — even when you're not in the building. For maximum security, integrate your door entry system with [CCTV cameras](/services/cctv-installation) and an [intruder alarm](/services/intruder-alarms). Who It's For ### Properties That Need Controlled Access Homeowners wanting to verify visitors before opening the door Landlords managing access across multiple flats or HMOs Property managers responsible for communal entrance security Office managers controlling staff and visitor access Care homes and sheltered housing with vulnerable residents Any building replacing a broken or outdated intercom system The Risks ## An Unlocked Building Is an Open Invitation Without proper access control, you have no way to verify who enters — and no record of who was there. ### Unauthorised Entry Without a functioning entry system, anyone can access your building. Tailgating, propped-open doors, and shared keys create security gaps that put every occupant at risk. ### Key Management Chaos Lost keys mean changing locks for the entire building. Shared keys can be duplicated without your knowledge. Fob-based systems eliminate these risks — lost fobs are deactivated in seconds. ### Liability Exposure Landlords and property managers have a legal duty to secure communal areas. A broken or absent entry system can result in liability issues if an incident occurs. Our Process ## From Assessment to Controlled Access 01 ### Free Access Assessment We assess your building's entry points, occupancy requirements, and access control needs. For flats and HMOs, we evaluate the number of units and intercom requirements. 02 ### System Recommendation You receive a clear plan detailing the intercom type, lock mechanism, wiring requirements, and a fixed-price quote covering all equipment and installation. 03 ### Professional Installation Our engineers install the door panel, internal handsets or monitors, electric lock mechanism, and all associated wiring. Everything is tested at each stage. 04 ### Access Configuration We programme all unit assignments, configure fob/code access, set up any smartphone integration, and test every entry and release point in the building. 05 ### Handover + Training We walk building managers or homeowners through operation, fob management, and troubleshooting. Your 12-month parts and labour guarantee begins. Benefits ## What You Get With Every Door Entry Installation ### Control Who Enters Verify every visitor before granting access. Audio and video intercoms let you see and speak to whoever is at the door — whether you're inside or miles away. ### Smartphone Door Release Answer the intercom and unlock the door from your phone. Ideal for letting in deliveries, tradespeople, or guests when you're not at home. ### No More Lost Keys Fob and code-based access eliminates the risk and cost of lost keys. Fobs can be added or deactivated instantly — perfect for multi-tenant buildings. ### Multi-Unit Capability Our systems support individual unit calling for blocks of flats, HMOs, and commercial buildings. Each resident has their own handset, code, or fob. ### Integrated Security Door entry systems integrate with CCTV and alarm systems for comprehensive access control. Capture video of every visitor alongside your surveillance footage. ### Vandal-Resistant Panels External door panels are built from brushed stainless steel or die-cast aluminium with anti-tamper screws. Designed to withstand daily use and deliberate damage. Technical Detail ## Entry Systems, Lock Types & Access Technology ### Audio Intercom Systems Audio intercoms are the most cost-effective entry system. A visitor presses a call button on the external panel, and the occupant answers via an internal handset. A door release button unlocks the electric lock remotely. Audio systems are reliable, simple, and ideal for single-dwelling properties and smaller buildings. ### Video Intercom Systems Video intercoms add a built-in camera to the external panel, allowing occupants to see visitors on an internal monitor or smartphone screen before granting access. This provides significantly better security — particularly for properties where the front door isn't visible from inside. Modern video intercoms offer wide-angle HD cameras, night vision, and photo/video logging of every call. ### Smart / IP Intercom Systems IP-based intercoms connect to your home or building network and forward calls to your smartphone. You can see visitors, speak to them, and release the door from anywhere with internet access. These systems are increasingly popular for Airbnb hosts, landlords, and anyone who needs remote access management. ### Electric Lock Mechanisms **Electric strikes** replace the standard door strike plate and release when triggered by the intercom. They're the most common mechanism for intercom-controlled doors. **Magnetic locks (maglocks)** use electromagnetic force to hold the door shut. They offer higher security than electric strikes and are commonly used in commercial buildings and communal entrances. **Electric drop bolts** provide a secure locking mechanism for glass doors and gates where conventional locks aren't suitable. ### Fob & Code Access Proximity fob readers allow residents to unlock communal doors without keys. Fobs are assigned individually and can be deactivated instantly if lost or stolen. Code access panels provide keypad entry as an alternative or backup. Multi-factor access (fob + code) is available for higher-security applications. ### Multi-Unit & Commercial Systems For blocks of flats, HMOs, and commercial buildings, we install systems with individual unit calling buttons, resident directories, and separate access credentials for each occupant. Systems scale from 2 units to 100+ with modular panel expansion. Integration with CCTV provides video logging of every visitor. ### Related Services [Security System Installation](/services/security-system-installation) [Intruder Alarms](/services/intruder-alarms) [CCTV Installation](/services/cctv-installation) FAQ ## Door Entry System Questions Answered ### How much does a door entry system cost? ### What's the difference between audio and video intercoms? ### Can I answer the intercom from my phone? ### How long does installation take? ### Can you install a system for a block of flats? ### What type of lock mechanism do you install? ### Can a door entry system integrate with CCTV? ### What happens during a power cut? ### Can I add or remove fobs myself? ### Do you service and repair existing door entry systems? ![Eagle All Security engineer installing CCTV camera on a London property](/assets/installer-selfie-DpP39Jss.jpg) ## Take Control of Who Enters Your Building Free access assessment, fixed pricing, and installation within days.
