“We had DNA Electrical Systems update our home security system today so we can monitor it through our mobile phones.

John set up the accounts and Nick did the installation and between them they ensured that, before Nick left, we were confident we knew how to operate the updated system, and that it is working.

John also listened when I asked for customisation, e.g. the amount of exit/entry time, and naming of each zone so we know exactly what sensor is being triggered (& removing unused zone to simplify the display).

We appreciated their patience and their commitment to ensuring the customer has the information they need to confidently operate the system.” — Greg & Audrey Byrne
