Access Control & Door Entry Systems for Every Property Type

Every property has different entry points, different risks, and different people who need access. Whether you are looking to secure a family home or manage permissions across a large commercial site, the right system starts with understanding exactly what you are protecting. Here is how we help.

For Homeowners & Residential Properties

You want to know who is at your door before you open it, and you want the ability to grant or restrict access without handing out physical keys. Maybe you have had an unwanted caller, or you simply want the convenience of letting someone in from your phone while you are upstairs.

A video door entry or electronic access control system gives you that control. We design discreet, easy-to-use residential systems with remote viewing and door release from your smartphone or tablet. Our engineers visit your property, assess the layout, and recommend the right setup for your front door, gate, or communal entrance. No jargon, no pressure, and a clear price before any work begins.

For Business & Commercial Premises

You manage staff across multiple doors or sites. You need a full audit trail for compliance and insurance purposes. You want to revoke access instantly when someone leaves the business, without changing a single lock.

A commercial access control system gives you that level of control, and it can integrate with your existing CCTV, intruder alarms, and fire detection for a complete security setup. Every system is designed around your site, your staff structure, and your compliance needs.

For Facilities Managers & Multi-Tenancy Buildings

Managing access across floors, zones, and multiple tenants means permissions change constantly. A system that cannot keep up creates gaps. Cloud-based access control lets you add and remove credentials from anywhere, in real time, with a full log of every access event.

We install networked access control systems with central remote management across all your buildings. Maintenance contracts keep every door controller and reader working, and our support team is available to help when something changes.

What Is the Difference Between Door Entry and Access Control?

Door entry systems and access control systems are closely related, and many installations combine both. Understanding the difference helps you choose the right setup for your property.

Door Entry Systems

Manages access at a single point of entry — typically through a video intercom, audio panel, or keypad linked to a door release mechanism. A visitor arrives, presses the call button, and you decide whether to let them in. Straightforward, effective, and suits most residential properties and smaller commercial premises.

Access Control Systems

Goes further — managing permissions across multiple doors, zones, and users through a central controller or cloud platform. Credentials are programmed per user, access can be restricted by time of day or day of the week, and the system logs every entry and exit event with a date, time, and user identity. Permissions can be changed instantly, remotely, without any physical work on the door.

	Door Entry Systems	Access Control Systems
Primary use	Single-point visitor management	Multi-door permission management
Typical setting	Residential, small commercial	Commercial, industrial, multi-site
Key components	Intercom panel, monitor, door release	Controller, readers, management software
Credential types	PIN code, audio or video call	Keycard, fob, biometric, mobile app
Monitoring capability	Entry events at one point	Full audit trail across all doors

Many properties benefit from both. A residential apartment block, for example, uses video door entry at the main entrance and keycard access control for communal floors and storage areas. We will recommend the right combination during your free site survey.

Types of Access Control & Door Entry Systems

Choosing the right system means understanding what each option does and what it is best suited for. Here is a plain-English breakdown of the main types we install.

Access Control Types

Video Door Entry Systems

Video door entry systems combine an external door station with a colour monitor inside the property. When a visitor arrives, you can see and speak to them before releasing the door. Modern systems support mobile app integration, so you can answer from anywhere and grant access remotely.

These systems suit houses, flats, apartment blocks, and gated properties. Two-wire wiring configurations keep installation clean and straightforward, with minimal disruption to existing walls or cabling.

Residential — suitable for home and residential door entry installations.

Audio Door Entry Systems

Audio-only door entry systems provide a reliable, lower-cost alternative to video intercoms where a visual feed is not required. A visitor presses the call button, you speak to them through the panel, and release the door if appropriate.

These systems suit smaller commercial premises, secondary entrances, and properties where simplicity and budget are the primary considerations.

Residential / Commercial — suitable for simple door entry setups and secondary access points.

Keycard & Fob Access Control

Keycard and fob systems use RFID technology to grant access. Each user is issued a credential that is programmed into the system with their specific permissions. Present the card or fob to the reader, and the door releases. If a card is lost or a staff member leaves, the credential is deactivated in seconds — no locksmith required.

These systems are the most common choice for offices, commercial buildings, and multi-tenancy properties where staff numbers change regularly.

Commercial — suitable for offices, multi-tenancy buildings, and staff access control.

PIN Code Entry Systems

Standalone PIN code keypads offer a simple, cost-effective electronic door entry solution for lower-risk environments. Users enter a code to gain access, and codes can be changed without any hardware replacement.

PIN systems suit small offices, storage facilities, secondary access points, and locations where issuing individual credentials is not practical.

Residential / Commercial — suitable for simple controlled access and lower-risk entry points.

Biometric Access Control Systems

Biometric access control systems verify identity using a physical characteristic, most commonly a fingerprint, facial recognition scan, or iris pattern. Because the credential is part of the user, it cannot be shared, lost, or stolen.

These systems are used in high-security environments where tight control over access is critical: server rooms, pharmacies, laboratories, research facilities, and any area where data protection or regulatory compliance demands a higher level of authentication. Biometric data is classified as special category data under UK GDPR, so biometric access control should be specified with data protection, consent, retention, and access governance carefully considered.

Commercial — suitable for high-security areas and restricted access environments.

Mobile & App-Based Access Control

Mobile access control replaces physical credentials with a smartphone. Users receive a digital credential on their phone and present it to a reader via Bluetooth or NFC. Permissions are managed through a cloud platform, making it straightforward to add new users, update access levels, and track activity from any device.

These systems suit businesses that want a modern, keyless setup that fits naturally into existing workflows — and they reduce the cost and time of issuing and replacing physical cards.

Commercial — suitable for modern, app-based access management.

Cloud-Based Access Control

Cloud-based access control systems manage credentials, permissions, and audit trails through a web platform rather than a local server. This makes them easy to scale, simple to manage remotely, and straightforward to expand when you add new doors or new sites.

For businesses with multiple premises or growing teams, cloud access control reduces the administrative burden and gives managers real-time oversight across every location from a single dashboard.

Commercial — suitable for multi-site access management and growing teams.

Door Entry Systems with Lock Release

A door entry system is only as effective as the lock release mechanism behind it. Understanding the hardware options ensures your system is both secure and compliant.

Electric Strikes

Release the door latch when a signal is sent from the intercom or access controller. The most common lock release type for timber and UPVC door frames — works cleanly with most residential and commercial door entry setups.

Magnetic Locks (Maglocks)

Hold the door closed using an electromagnetic force. When access is granted, the current is interrupted and the door releases. Highly reliable and well suited to heavy commercial doors, but require careful consideration under fire regulations.

Electric Bolts

Used where a more robust physical barrier is needed. The bolt retracts on an access signal and re-engages automatically when the door closes — suitable for high-security applications requiring a stronger mechanical hold.

Fail-Safe vs Fail-Secure

How a lock behaves during a power cut is a critical safety and compliance consideration.

Fail-Safe

Lock releases when power is lost. Required on fire escape routes to ensure people can always exit the building — a legal requirement under fire safety regulations.

Fire escape routes

Fail-Secure

Lock remains locked during a power failure. Appropriate for secure areas where unauthorised access is the greater risk — server rooms, data stores, or restricted zones.

Secure & restricted areas

Our engineers specify the correct option for each door based on its location, use, and fire safety requirements.

How Access Control & Door Entry Installation Works

Knowing what to expect makes the whole process easier. Here is how a typical installation works from first contact to a fully operational system.

Free Site Survey

An accredited Bell surveyor visits your property to assess entry points, identify security requirements, and discuss your priorities. We look at door types, cable routes, existing infrastructure, and any specific access needs. There is no obligation and no charge for this visit.

System Design & Quote

Based on the survey, we design a system that fits your property and your budget. You receive a fixed-price quote covering hardware, software, cabling, installation, and configuration. No hidden costs and no surprises.

Professional Installation

Our NSI Gold approved Bell engineers carry out the installation with minimal disruption to your daily routine. Equipment is securely mounted, cables are concealed where possible, and every door controller, reader, and credential is configured to your specification. Residential installations typically take one day. Commercial projects vary depending on the number of doors and any integration work required.

Testing & Commissioning

Once installed, every door, credential, and permission level is tested before handover. We check that access rights are correct, that the audit trail is logging accurately, and that remote management is functioning. We also walk you through the system so you are confident using it from day one.

Ongoing Support & Maintenance

After installation, we offer planned maintenance contracts and 24/7 support for commercial customers. Our engineers are on call for repairs, and our monitoring team is available around the clock for systems connected to our Alarm Receiving Centre. If something changes — staff numbers, site layout, or security requirements — we are one call away.

Benefits of Access Control & Door Entry Systems

A professionally installed access control and door entry system does more than secure a door. Here is what you actually gain.

Enhanced Security

Electronic access control reduces the risks that come with physical keys. Modern credentials are easier to manage than traditional keys, and lost or compromised credentials can be revoked without replacing locks. You decide who can go where, at what time, and on which days — without any physical work on the door.

Full Audit Trail

Every entry and exit event is logged with the date, time, and the identity of the credential used. That record is available instantly, searchable, and can be exported for compliance reporting, insurance claims, or internal investigations. Many industries require this level of documentation, and a properly configured access control system generates it automatically.

Remote Management

Grant or revoke access from anywhere using a mobile app or cloud management platform. Add a new team member on their first day before they arrive, or remove a former employee's access the moment they hand in their notice. For businesses managing multiple sites, this removes the need to be physically present to make changes.

Integration with CCTV & Alarms

Access control works best as part of a broader security setup. When your door entry system, CCTV, and intruder alarm are connected on a single platform, an event at one can trigger a response across all three. A forced entry attempt can simultaneously trigger CCTV recording, sound an alarm, and send an alert to your monitoring centre.

Scalability

Start with one door and a handful of users. Expand to hundreds of doors across multiple sites without replacing the system. Cloud-based access control and IP-based door controllers are built to grow with your business, meaning the investment you make today can still support your needs years from now.

Insurance and Compliance Support

A professionally specified access control system can support insurer discussions by improving control over entry points, restricted areas, and audit records. Your broker or insurer should confirm any specific policy requirements or premium impact. Bell provides clear documentation to support your facilities, compliance, and security records.

Why Choose Bell for Your Access Control Installation?

NSI Gold Approved for Relevant Security Work

Bell Fire & Security holds NSI Gold approval for relevant security system work, supporting a quality-led approach to system design, installation, documentation, and ongoing maintenance. For access control and door entry projects, this means your installation is handled by a trained team with clear procedures, proper records, and an understanding of how electronic access should support wider building security.

Where access-controlled doors interact with escape routes, fire alarm systems, or the building’s fire strategy, our engineers specify the installation carefully so security does not compromise safe evacuation. The result is a practical, properly documented system that supports your property, your users, and your insurer or facilities requirements.

Over 100 Years of Experience

Bell Fire & Security has been protecting homes and businesses in Scotland since 1919. That is over a century of engineering experience, thousands of completed installations, and a reputation built on consistent, reliable service. More than 60% of our work comes from repeat customers — which tells you more about what it is like to work with us than any sales claim ever could.

Accredited Engineers

Every member of our installation team holds industry-recognised qualifications and manufacturer certifications. Our engineers undergo regular training to stay current with new technology, evolving installation standards, and changes in compliance requirements. When a Bell engineer arrives at your property, they are qualified, experienced, and accountable for the work they carry out.

Full Lifecycle Service

We do not install and disappear. From the initial site survey through to ongoing maintenance, system upgrades, and repairs, everything is handled by one team. That means one point of contact, consistent records, and no gaps between different contractors trying to manage different parts of your security. If something changes — your team, your premises, your requirements — we are already familiar with your system.

Flexible, Tailored Solutions

No two properties are the same. A four-flat residential block needs a different setup from a 50-person office, and a warehouse with shift patterns needs different access rules from a school with visiting contractors. We specify systems around what you actually need, not around what is easiest to sell. The result is a system that fits the way you use your building.

Industries We Serve

Access control and door entry systems are used across a wide range of sectors. Here is how we approach each one.

Offices & Commercial Buildings

Manage staff access by floor, department, or security zone. Visitor management integrates directly with the access control platform, giving receptionists and facility managers a complete picture of who is on site at any time.

Schools & Education

Protecting pupils and staff means controlling every entrance point without creating a fortress. We install systems that allow quick, legitimate access for authorised users while giving staff full visibility of everyone on site.

Healthcare & Hospitals

Restrict access to medication stores, server rooms, staff-only areas, and sensitive records while maintaining clear audit trails for internal governance, safeguarding, and Scottish regulatory expectations.

Retail & Hospitality

Staff entrances, stockrooms, back-of-house areas, and management offices all need controlled access. We install systems that reduce the cost and disruption of rekeying when staff change, while giving managers remote oversight.

Warehouses & Industrial

Large sites with multiple access points, shift-based working, and high-value goods need robust perimeter access control. Time-zone restrictions, zone-based permissions, and full audit trails are standard features of the systems we install for industrial clients.

Residential Apartments & Blocks of Flats

Video door entry at the main entrance, keycard or fob access for communal floors, and individual apartment entry systems can all be managed from a single platform. We work with property developers, housing associations, and private landlords across Scotland.

Public Sector & Government

Public sector installations require compliance with specific procurement and security standards. Access control and door entry systems specified around procurement requirements, site security policies, audit trails, and controlled access needs.

Technology & Data Centres

Data protection requirements mean physical access to server rooms and secure areas must be controlled and documented. We install biometric and multi-factor access control for technology facilities where the cost of a breach goes well beyond the physical.

Frequently Asked Questions About Access Control & Door Entry Systems

What is the difference between door entry and access control?

Door entry systems control access at a single point of entry, typically through a video intercom, audio panel, or keypad connected to a door release. Access control systems go further — managing permissions across multiple doors and users via a central controller or cloud platform, with credentials, time-zone restrictions, and a full audit trail. Many installations combine both. A residential apartment block, for example, uses video door entry at the main entrance and keycard access control for communal floors.

What are the 4 types of access control?

Role-Based Access Control (RBAC) — permissions are assigned based on a user’s role within an organisation, so a warehouse operative gets different access rights from a senior manager without any manual configuration per person.
Discretionary Access Control (DAC) — the resource owner sets permissions individually, giving more flexibility but requiring more ongoing management.
Mandatory Access Control (MAC) — permissions are set by a central authority and cannot be changed by individual users, typically used in high-security government or military environments.

Attribute-Based Access Control (ABAC) — access decisions are based on a combination of user attributes, environment conditions, and resource type, allowing highly granular control across complex organisations.

What is an EAC system?

EAC stands for Electronic Access Control — a system that uses electronic credentials such as keycards, PIN codes, biometrics, or mobile devices to grant or restrict access to doors, gates, or secure areas. EAC systems replace traditional mechanical locks with programmable, auditable, and remotely manageable access points. Bell installs EAC systems for both residential and commercial properties across Scotland.

Can access control systems integrate with CCTV?

Yes. Bell designs and installs integrated security systems that bring access control, CCTV, intruder alarms, and fire detection together on a single platform. When an access event occurs — whether a successful entry, a failed credential attempt, or a forced door — your CCTV can automatically begin recording at that point. This correlated evidence is far more useful than footage from a standalone camera system.

How much does access control system installation cost in Scotland?

Costs vary depending on the number of doors, the credential type you choose, whether the system is wired or wireless, and whether you add cloud management or ongoing monitoring. A straightforward single-door electronic access system for a home costs considerably less than a multi-site commercial installation with biometric readers and cloud management. The most accurate way to get a price is through a free site survey, where we assess your property and provide a fixed-price quote with no obligation.

Are access control systems suitable for residential properties?

Yes. From a simple video door entry system for a single front door to a full keycard and intercom setup for a 50-flat apartment block, Bell installs residential access control systems across the full range. Home systems typically focus on video or audio door entry with mobile app integration, while larger residential buildings benefit from the full credential management and audit trail features of a commercial-grade system.

How long does access control installation take?

A single-door residential installation usually takes one day. Commercial installations with multiple doors, zone configurations, and integration with existing security systems typically run between one and three days depending on scale. We confirm the timeline at the quoting stage so you know exactly what to expect before we begin.

What credentials can be used with an access control system?

The most common options are keycards and fobs using RFID technology, PIN code keypads, biometric readers using fingerprints or facial recognition, and mobile credentials using Bluetooth or NFC via a smartphone app. Many systems support multiple credential types on the same door, which is useful when you want to offer both a card and a PIN option for different users. We will recommend the right credential type for each door during the system design stage.

What happens to access if there is a power cut?

Access control systems include battery backup to maintain operation during short power interruptions. For doors with lock release mechanisms, the system is specified as either fail-safe (the door releases during power loss, required on fire escape routes) or fail-secure (the door remains locked during power loss, appropriate for secure areas). Our engineers specify the correct option for each door based on its location and fire safety requirements.
