I am interested in the growing use of technology capable of detecting 'sound events' which is being used, often in conjunction with CCTV systems, to monitor public areas. This technology is designed to use audio inputs to detect sounds such as gun shots, human screams or shouts, speeding vehicles or anti-social behaviour to improve public safety. Here are some examples of the type of technology I'm referring to:

I am trying to establish the extent to which this technology is currently being used in the UK by local authorities. Specifically, I would like to ask:

1. Is your local authority using, or has it previously tested, sound detector technology as described above to monitor public areas for emergencies or anti-social behaviour?
Yes we have sound detector technology linked to our CCTV camera systems.

2. If yes, please provide details of how many sound detectors or sound detector-equipped CCTV cameras you are operating and when they were installed.
We have one camera with sound detection fitted in the following car parks to assist with ASB. Carnival Multi storey car park. 1 camera with audio listening not recording sound.
Thames Valley Park & Ride 1 camera with audio listening not recording sound.
