About Control Freq:

Control Freq was started in 2007 with a clear vision of what mobile technology could be and here we are. Mobile is everywhere and everything to everyone.

When Control Freq first started introducing mobile technology for opening security gates by phone in 2007, 3 months before the first iPhone was released, it was a struggle to convince customers it was the way forward.

Control Freq persevered and pivoted to develop one of the first GSM intercoms ever introduced. This learning curve resulted in a range of new products spanning applications and industries worldwide with an online e-commerce platform to distribute the technology.

The latest technology features a new access control range called FUSION. Including the most reliable, advanced and well-made GSM intercom range available, FUSION combines traditional access control, such as ANPR, with mobile technology to form a complete range of remotely manageable access solutions.

Control Freq now powers the parking industry with turnkey on-demand access control solutions to instant parking providers (parking apps) who are driving the 'Airbnb of Parking' revolution.

Item arrived very quickly, and words fantastically - used to replace an old landline auto dialer for monitoring a customers' steam boiler. The new unit will be expanded to monitor 3 other critical systems in the factory. We had an initial niggle that Support were able to resolve quickly. Wouldn't hesitate to recommend, and Control Freq are our go-to for GSM applications :)

They responded very promptly and positively to my enquiry, offering a suitable solution at a reasonable price. The original equipment was over 5 years old and it was upgraded and returned very quickly. Control Freq then helped setting it up and ensuring the best possible communication. It appeared to be 24/7 attention and definitely above and beyond what was expected.

Many thanks. Glad we could sort it out for you. Noel
I purchased a 1 button GSM intercom c/w keypad for one of my customers. I found it to be an excellent product and had great features, it worked perfectly and also the tech staff are very helpful especially Noel who dealt with my order and even the initial programming to get me up and running on site. I would highly recommend this company and will be using them again. Tony Byrne Director ATB Electrical Systems Ltd

I'm from the U.S. where 2G was shut down as of January 1, 2017. I have used a GSM intercom for many years and this is my third unit. The first quit working (American made) and their support tried at first but dropped me when nothing else worked, this unit was just okay. The second one came from the UK but different company and had some problems and support was excellent although I am the one that fixed it (my phone messaging was on "unicode" rather than "automatic", which was probably the issue with the first unit). The second unit was 2G and that company did not have a 3G version. After a lot of internet searching I found Control Freq and from what I could see was the best unit out there. I bought the 3G GSM intercom (my third GSM unit) and I have to say the best quality of all three. I did have some issues but Noel got me back on track and it works beautifully! While it is a bit more expensive than the second unit I had which was all plastic this one is all metal and stainless steel. I am not a big "app" person but this one comes with that option and is very easy to understand and use for programming and operation. Needless to say I am very satisfied with my purchase, Thank you Noel and team for a Great Job!
