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. Please find copies
of these reports and more on the RESEARCH page.
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. In all cases, we strongly suggest that you
contact one of our dealer / installers on our ‘Distributors’
page. If you cannot find a company local to you, please
contact us and we will find a local installer for you.
How robust is the unit?
The unit is housed in a die-cast
alloy and steel vandal-proof casing and is therefore very
strong. CSS recommend that the unit is mounted at least 3
meters above ground level to reduce the risk of vandalism.
For added security, CSS 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.
The Music Mosquito is supplied with an RF remote control as
standard but can also be run off a timer.
The Mini-Mosquito simply turns on / off at the power socket.
How loud is the Mosquito™?
Mosquito™ MK4 has a maximum dB output of 108 dB, however, in
order to access volumes greater than 95 dB, users will
require an additional micro-chip from CSS.
The Music Mosquito whilst having a built-in AGC that will if
required maintain the output volume at 5 dB above background
levels has a maximum volume of 100 dB.
The Mini-Mosquito has a maximum volume of 85 dB
