100% Focused on Mobile Hardware & Cloud Software

ControlFreq started in 2007 with the intention of bringing mobile phone based access control to the property management industry. It was a bit early so we pivoted. We tried to sell it to the installers. They preferred remote control sales over GSM gate openers. We then developed the first GSM intercom we know of in the UK. We made a GSM intercom PCB to fit inside 3rd party enclosures and started selling GSM intercoms. That was the beginning of ControlFreq. Our business split between e-commerce and offline custom solutions. The latter is now our core focus so we're seeking Reseller partners to join us to help shift kit whiole we do what we do best – design, develop, fabricate, assemble & support a complete range of rock-solid reliable GSM systems, for multiple industries and applications, with the absolute best-in-class online back end for remote device/user management and ongoing value-add services.

Access, controlled.

Advanced hybrid access control managed online for a better experience for all involved. For Installers, it's easier to install, simple to configure & universally compatible with any existing entry system. Site managers gain secure control & end users get modern-day  hassle-free service with ZERO disruption.

Integrated QR-reader access control with user management via booking app. 

QR-codes are one of the most adaptable, flexible, affordable & integrat-able form of 'throw away' access control options available. The QR-code can be saved on a user's phone via email confirmation of a booked service ie: parking or rental service. The QR code can also be printed on paper and shown to the QR reader for access. QR-codes are dynamically generated and sent to the user booking the service so they're ideal, and intended, for 3rd party on-demand booking services such as pre-book parking where temporary access is required.


PIN code access control with time/day/date restrictions  – managed online.

Remotely managed restricted user access is critical to maintain security of any building or car park. In particular, if the parking operator is a 3rd party service, it's important that users sent to the car park are restricted to only the time of their booking with event logged history to add another layer of visibility.


Handsfree vehicle access control with long-range adhesive RFID tokens.

Long-range RFID for vehicles is a simple approach to managing vehichle access for permanent users of a car park. Compared to ANPR, where users are required to have their vehicle on a whitelist to avoid parking charge notices (PCN), an adhesive ID token is mounted to authorised vehicle windscreens. The token has a unique ID which is managed using our web-based management platform. Vehicles can still be restricted by time/day/date restriction. All users entry events are logged online for admin use.


Secure-ID remote controls with online management of user access restrictions.

ControlFreq access control includes remote controls that operate with a Wiegand receiver that connects to any of our access control or GSM intercom systems. Add traditional remote keyfob access with the additional benefits of web and app-based user management.

ControlFreq offer professional branding for GSM intercoms. Suitable for harsh outdoor environments & heavy commercial use, deliver a professional 'on brand' experience from the first customer touch-point in any use case. What the customer will see first is your brand, not ours.
