Access Control Systems — Intelligent Entry Solutions for UK Businesses

From standalone door controllers to fully networked multi-site access management — Prism designs, installs and maintains access control systems that keep the right people in and the wrong people out.

Control Who Enters

Intelligent Access Control, Tailored to Your Site

Access control gives you the ability to manage, log and audit exactly who enters which part of your building — and when. Unlike a physical key, access credentials can be issued and revoked instantly, providing a level of security and flexibility that traditional locking simply cannot match.

Whether you need a single door controlled by a key fob reader, or a complex multi-site system managing hundreds of doors with time-zone scheduling and full audit trails, Prism has the expertise to design and deliver it.

Credential Technologies

How People Gain Access

🔑

Key Fob & Card

RFID or NFC proximity fobs and cards. The most common access credential — fast, reliable and low-cost to replace if lost.

📱

Mobile Credentials

Open doors using a smartphone via Bluetooth or NFC. No fob to carry — ideal for companies already using mobile device management.

🔢

PIN Keypad

Individual or shared PIN codes for door control. Can be combined with fob credentials for two-factor access to high-security areas.

👤

Biometric

Fingerprint or facial recognition for areas requiring the highest level of access security. No credential to carry or forget.

Common Questions

Frequently Asked Questions

For most offices, a proximity fob or smart card system is the most practical solution — quick to use, easy to manage and simple to cancel if a credential is lost. For higher-security areas, biometric readers (fingerprint or face recognition) add an additional layer of identity verification. Our engineers will recommend the right technology based on your building layout, footfall and security requirements.
Yes. Integrating your access control system with CCTV allows you to automatically record video footage every time a door is accessed, creating a linked audit trail of who entered, when, and what the camera captured at that moment. This is particularly valuable for investigating incidents and for insurers.
Modern networked access control systems include management software that allows administrators to add or remove users, set access schedules, view audit logs and lock or unlock doors remotely — from a browser or mobile app. Cloud-based systems take this further, requiring no on-site server. We install and configure management software as part of every networked installation.
All our access control hardware includes battery backup to ensure continued operation during a power failure. Door controllers and electronic locks maintain their programmed state (fail-safe = unlocks on power loss; fail-secure = remains locked), and we advise on the correct fail mode for each door during survey, taking into account fire evacuation requirements.
Yes. Networked and cloud-based access control systems can manage unlimited doors across multiple buildings or sites from a single management platform, with the ability to set different access rights per person, per door and per time of day. This is ideal for businesses with multiple premises or large campuses.
