About TDSi

Why TDSi?

Protecting and securing your building, assets and people is a high priority for any business. However, those responsible for building security often find themselves overwhelmed by choice.

In order to find the right solution, there are a number of considerations to be made such as who is permitted access to which areas, what happens in case of a fire or external threat? How do we keep track of footfall and which types of locks will we need? In addition, consideration for the cost of the system, its longevity and ease of use all come into play when searching for the ideal product fit.

TDSi are specialists in Access Control, offering a range of superior products that not only answer the security challenges of the 21st century but delivers peace of mind to those who trust in our expertise and experience.
