Kingshaven Resident

“I would like to thank Ryan and Hein for a stellar job installing our fibre and going beyond the call of duty to make sure our network was running optimally. Quick response to enquiries and excellent customer service.”

Linda Mittan

Tact Surveillance

I am always impressed with the service that we receive from Demux. Both Hein and Ryan are super efficient and very knowledgeable in their field. We have worked with them now for over a year and they have addressed each installation and service very effectively and have always strive to meet every deadline.

They are great to work with and not scared to share their information to us in a way that we all understand and by this have also learnt from them considerably. Very attentive indeed

Their technical support is exceptional, most reliable and they are always easy to reach

Demux are highly professional and will remain our first call for all future fibre and camera installations

Former Body Corporate Chairman - ocean mist

“We confirm that DEMUX provided security products and services to the Ocean Mist Big Bay complex over the last two years. We found their supplies and services satisfactory. Ryan Minnaar was instrumental and very helpful in this regard.”

Clifford Van Rooyen

Service Manager - PORSCHE

“To whom it may concern,

I am writing this letter to recommend the services of Demux to you.During the past three years DEMUX has worked on various different projects at Porsche Cape Town and the work has always been of a high standard.

One of the first projects they worked on pointed out their vast knowledge and experience by finding the optimal solution, pointing out waste and as a result saving us money. In our opinion it has been the knowledge and creativity that resulted in such impressive results.

We strongly recommend the services of Demux and look forward to a long term relationship with this company.”
