Mosquito Crowd Dispersal
Mosquito™. A non-invasive solution to a very modern urban problem.
It is an effective deterrent that causes no physical pain or damage, even in the event of long term exposure.
The system generates a pulsed, near ultra sonic tone at around 16KHz, close to the limit of the hearing range of people under 25 years of age. The sound, though not painful in any way, becomes highly annoying after 5 or so minutes exposure. The result is that most under 20s leave the immediate area, whilst the majority of those over the age of 30, because of natural age related hearing loss, either just hear, or, as in most cases, are totally unaware of any noise.The system is designed to be used for up to 20 minutes at a time. The unit incorporates a 20 minute cut-off time to avoid unnecessary annoyance.
Mosquito™ complies with the HSE 2005 guidelines and is already widely used by police and local authorities around the UK.
Mosquito is an evolutionary device specifically designed to disperse groups of youths from areas they are not wanted:
