      Angela Holy-Hasted

    • We have been SDS customers for 12 years and cannot fault the service they provide. I have total faith in their security services. The customer service is exceptional and when I do stupid things like put the alarm on from habit forgetting I am leaving my mum in the house they are very understanding! When we renovated our home we went through all options available to us and I feel we got really good advice and were not sold anything we didn't need.
