The Mosquito™ Anti-Vandal System 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 behaviour 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 Anti-Vandal System has been described as “the most effective tool in our fight against anti social behaviour”. Shopkeepers 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.

The new Mosquito MK4 Multi-age now has two functions. Either set the device to 17KHz to disperse groups of troublesome teenagers OR set it to 8 KHz to disperse people of ANY AGE from areas where loitering can be an issue such as subway terminals, car parks or any areas where people feel insecure at night due to other people loitering in the shadows etc.

FAQs
How does the Mosquito™ system work?
Mosquito™ is essentially a sounder unit that emits a very high frequency modulated tone that is completely harmless even with long term use. The unit has been thoroughly tested by the NPL, NHS, ISVR, RSPCH, BSHC etc. to ensure it complies with all relevant legislation.



I am not a teenager, will the Mosquito™ annoy me?
This is very unlikely and research has shown that the majority of people over the age of 25, have lost the ability to hear at this frequency range. It should be borne in mind, however, that the unit usually has the desired effect – moving the crowds away – within just a few minutes, at which time the unit can be turned off. So even if you are able to hear the noise to some degree, you would not have to put up with it for long.

What about dogs?
Although dogs have very acute hearing and are easily able to hear at this frequency, extensive testing shows that it does not appear to bother them.

How quickly does it work?
The longer someone is exposed to the sound, the more annoying it becomes. Field trials have shown that teenagers are acutely aware of the Mosquito™ and usually move away from the area within 5 – 20 minutes. The field trails also suggest that after several uses, the groups of children / teenagers tend not to loiter in the areas covered by the Mosquito, even when it is not turned on.

What is the range of the Mosquito™?
The effective range is between 30 and 40 metres. The closer one gets to the unit the more effective it is.

What about teenage customers and my neighbours?
It takes 5 - 10 minutes for the presence of the sound to become annoying, even on teenagers. Genuine teenage customers who will only be within range for seconds whilst on their way in and out of the shop will not find the sound of significant consequence. As the transmission of the sound is directional and as high frequency short wavelengths do not travel effectively through solid objects, it is unlikely that there will be any adverse effect on neighbours.

Who installs the Mosquito™?
Although the unit is simple to fit, there are several considerations such as which setting to use, the angle that it is mounted at and the position it is mounted at, that require a professional alarm / security engineer to determine.

How robust is the unit?
The unit is housed in a die-cast alloy and steel vandal-proof casing and is therefore very strong. We recommend that the unit is mounted at least 3 meters above ground level to reduce the risk of vandalism. For added security, We can also provide a security cage to cover the unit.

How do I turn the Mosquito™ on and off?
Mosquito MK 4 has been designed with a range of built-in input terminals. These will allow you to connect the system to a range of triggers (input devices) such as a timer, remote control, PIR, CCTV system etc.


How loud is the Mosquito™?
Mosquito™ MK4 has a maximum dB output of 108 dB.
