Practical door entry solutions designed around how your organisation actually works.
If you are researching access control systems for businesses, you are probably looking for more than simply replacing keys or securing one entrance.
Today’s commercial security systems help organisations manage who can enter certain areas, improve accountability, and make buildings easier to manage day-to-day. The right setup should protect your premises while supporting how your team works now and in the future.
Need advice on the right system for your site? Contact us at info@nova-fs.co.uk or
01483 399129 to arrange a site survey and receive practical recommendations tailored to your building, users, and security requirements.
At Nova Fire & Security, we install and maintain commercial door entry systems across Surrey and surrounding areas. From small office setups to larger school and multi-building projects, we help clients choose reliable solutions that are practical, scalable, and easy to manage long-term.
The best access control system isn't necessarily the most complex. It's the one that fits the way your organisation operates, protects the right areas, and can adapt as your requirements change.
Why More Organisations Are Upgrading Their Entry Systems
Traditional lock-and-key setups can quickly become difficult to manage. Keys are often lost, copied, shared between staff, or expensive to replace when somebody leaves the organisation.
Controlled entry systems give organisations far more visibility and flexibility. Permissions can be updated instantly, restricted areas can be managed properly, and authorised users can move through buildings securely without relying on physical keys alone.
Many commercial sites are upgrading because they need:
- Better control over staff and visitor movement
- Improved safeguarding
- Easier management of contractors and temporary staff
- Audit trails showing who entered certain areas
- Integration with CCTV and alarms
- Systems that can expand in future
This is particularly important in schools, offices, warehouses, and hospitality settings where different users require different levels of access throughout the day.
The Main Types of Access Control Systems
There is no single solution that suits every premises. The right system depends on your building layout, security requirements, and how the site operates daily.
Keypad and PIN Entry Systems
Keypad systems allow authorised users to unlock doors using a PIN code.
These systems are commonly used for:
- Internal staff rooms
- Small offices
- Low-risk access points
- Temporary restricted areas
They are simple and cost-effective, for smaller premises. However, PIN codes can easily be shared between users, which reduces accountability. For this reason, they are usually better suited to lower-security areas.
Card and Fob Entry Systems
Card and fob systems remain one of the most popular options for commercial buildings in the UK.
Users receive a card or fob that only allows entry to approved areas. Permissions can be updated quickly if somebody changes role or leaves the organisation.
These systems work well for:
- Offices
- Schools
- Warehouses
- Commercial buildings
- Shared workspaces
We regularly install Paxton systems because they are dependable, scalable, and straightforward to manage.
Biometric Entry Systems
Biometric systems use fingerprint or facial recognition to verify users before entry is granted.
These setups are often chosen for:
- High-security environments
- Data rooms
- Restricted staff-only zones
- Premises where credential sharing is a concern
One advantage is that biometric credentials cannot easily be passed between users in the way cards or fobs sometimes can.
Businesses should also consider GDPR responsibilities, software updates, and ongoing maintenance requirements when choosing biometric technology.
Video Entry Systems
Video entry combines door access with live visual verification, allowing staff to see who is requesting entry before unlocking a door or gate.
These systems are particularly useful for:
- Schools
- Offices
- Apartment buildings
- Reception areas
- Sites with regular visitors
Modern video intercoms can often connect to mobile devices, allowing authorised users to manage entry remotely.
Touchless Entry Systems
Touchless technology allows users to gain entry without physically touching a reader or keypad.
This can include:
- Mobile credentials
- Facial recognition
- Proximity-based readers
These systems are useful in:
- Healthcare environments
- Schools
- High-traffic buildings
- Shared workplaces
They offer convenience while helping to reduce wear and tear on physical hardware.
System Integration
One of the biggest advantages of modern access control is the ability to connect multiple security and operational systems together.
Examples include:
- CCTV integration for event recording
- ANPR-controlled vehicle access
- Video intercoms for visitor management
- Intruder alarm integration
- Cashless vending and printing systems
mobile and smartphone access
Mobile entry systems allow authorised users to unlock doors using secure smartphone credentials instead of physical cards or fobs.
This approach is becoming increasingly popular in:
- Hybrid workplaces
- Multi-site operations
- Flexible working environments
- Shared office spaces
Benefits include:
- Faster user management
- Remote permission updates
- Reduced administration
- Lower physical credential costs
Cloud-based systems are becoming more common, particularly for organisations managing multiple locations.
Choosing the Right System for Your Premises
When planning a system, organisations should consider:
- Number of users
- Number of doors
- Future expansion plans
- Visitor management requirements
- Internal security zones
- Integration with CCTV or alarms
- Remote management needs
What to Expect From a Professional Installation
A successful installation starts with understanding how the building actually operates.
At Nova Fire & Security, every project begins with a site survey so we can assess:
- Entry points
- User requirements
- Existing infrastructure
- Future expansion plans
- Compliance considerations
From there, we design a tailored setup suited to the building and the people using it.
Our process typically includes:
- Site survey and consultation
- System design and recommendations
- Clear quotation
- Professional installation
- Testing and configuration
- User setup and training
- Ongoing servicing and support
Many clients worry about visible cabling or disruption during installation, particularly within schools or occupied buildings.
Our team takes pride in delivering tidy work with minimal disruption wherever possible. Clients regularly comment on the neatness of our installations and how efficiently projects are completed.
As an SSAIB-accredited company and Paxton partner, we ensure systems are installed to recognised industry standards and supported properly after completion.
Frequently Asked Questions
What is the best access control system for a small business?
This depends on the number of users, security requirements, and future growth plans. Many smaller organisations choose card or fob systems because they are simple to manage and can expand later if required.
Are mobile entry systems secure?
Yes, when professionally installed and configured correctly. Most cloud-managed systems use encrypted credentials and secure user permissions.
How often should commercial door entry systems be serviced?
Most commercial systems should be checked regularly to ensure firmware updates, lock testing, and emergency release functions remain compliant and reliable.
