Sittingbourne Multi Story Car Park

This is an indoor multi-story car park as part of Swale Borough Council, providing 317 car park spaces allowing easy access to local amenities.


The car park was prone to anti-social behaviour due to it being open 24/7 and young people using it as a gathering spot. This was causing thousands of pounds of damage to the facilities, particularly the lifts. A CCTV system was already in place however, the customer required an additional audio system to directly communicate with those causing damage.

The main challenge when completing this job was traffic management due to working in a live car park. We used cones and barriers to overcome this challenge and worked at times when the car park was at its quietest, in order to reduce any disruption to users.


Firstly, after the initial quoting of works dssl engineers attended site and finalised plans for running cables and confirmed all locations with supervisors. Cables and cable management was then installed to each speaker location.

Speakers were then installed and thoroughly tested, ensuring volume was at the optimal level needed, these were also zoned, allowing messages to be received by either the whole car park or just specific stairwells. 8 speakers were installed in total over a course of 3 days.


  • Increased safety for users of the car park.
  • Fully integrated with the existing control room.
  • Reduced anti-social behaviour.
