The Mosquito™ ultrasonic teenage deterrent is the solution to the eternal problem of unwanted gatherings of youths and teenagers in shopping malls, around shops and anywhere else they are causing problems. The presence of these teenagers discourages genuine shoppers and customers’ from coming into your shop, affecting your turnover and profits. Anti social behavior has become the biggest threat to private property over the last decade and there has been no effective deterrent until now.

Acclaimed by the Police forces of many areas of the United Kingdom, the Mosquito ultrasonic teenage deterrent has been described as “the most effective tool in our fight against anti social behaviour”. Shop keepers around the world have purchased the device to move along unwanted gatherings of teenagers and anti social youths. Railway companies have placed the device to discourage youths from spraying graffiti on their trains and the walls of stations.

With an effective range of between fifteen and twenty meters Compound Security Systems’ field trials have shown that teenagers are acutely aware of the Mosquito and usually move away from the area within an average of 8- 10 minutes. The system is completely harmless even with long term use. The Times newspaper in England reports that the device was first used at a Spar shop in Barry, South Wales, where the owner Robert Gough was enthusiastic about the device's success in driving away the local youths. "Either someone has come along and wiped them off the face of the earth, or it's working" he is quoted as saying. Since then, there have been literally hundreds of successful reports not only from police and local authorities, but also from business owners.

It seems that there is a very real medical phenomenon known as presbycusis or age related hearing loss which, according to The Merck Manual of Diagnosis and Therapy, "begins after the age of 20 but is usually significant only in persons over 65". It first affects the highest frequencies (18 to 20 kHz) notably in those who have turned 20 years of age". It is possible to generate a high frequency sound that is audible only to teenagers.

Is your business suffering from anti social youths driving your customers away or generally causing damage or nuicance?

Are you bothered by crowds of teenager’s hanging around your street and making life unpleasant?

Mosquito™ ultrasonic deterrent can solve your problem.

GSM Mosquito
CSS provide a remote control for the Mosquito, however, this has a range of only 50 meters. This is OK if there is someone on-site to activate the unit. Where staff are not present, the only other options are either a timer or a PIR, however, in certain situations, these can be problematic.

To this end, CSS have developed the GSM Mosquito. The unit can be activated and deactivated simply by sending a text message to it via a mobile ‘phone.

What advantage does this provide? Well, it removes the responsibility for using the device from local staff and allows a qualified person to decide if it is really necessary to activate the device. This will prevent the Mosquito from being used arbitrarily and incorrectly.

We envisage that when the site staff feels there is a problem, they can call a designated qualified person and explain the problem. If the qualified person feels that the situation warrants activation, he / she can activate that particular Mosquito. The Mosquito will automatically deactivate after 20 minutes, however, the unit can be deactivated sooner if required by sending another text message.

The Mosquito will have a SIM card already fitted. This card will be on a monthly pay as you use tariff with one of the major UK mobile networks (probably O2 as they have the best UK coverage). The monthly cost of this will be in the region of £11.00 (exact prices to be confirmed at time of ordering due to network tariff changes). Any mobile ‘phone on any network can be used by the qualified person / authority to send instructions to the Mosquito.

This ensures that the use of the Mosquito is solely in the hands of a qualified person and ensures that the unit is NOT abused.
