If you want to purchase a domestic burglar alarm but you are on a limited budget or frequently move house, then a wireless alarm system will probably be the right choice for you. This is because they are cheap and easy to install and can be easily removed and used again in another home.
There are three popular types of wireless alarm system, namely an audible system, an auto-dialling system or a monitored system. Audible systems are most popular but are also the least effective. With this type of system the alarm sounds but a response is dependent on individuals within earshot of the siren or bell. If your home is vacant when the alarm is triggered, this would have to be a neighbour or a passer-by. To minimize the number of calls due to false alarms, the police will not respond to an audible alarm report unless it is supported by other evidence that a crime is being committed. This is normally an independent witness dialling 999 who has seen suspicious activity at the property.
When an auto-dialling system is activated, it will send an image or message to a mobile phone designated by the installer. Once again, if your property is being broken into in your absence and you have been sent a message to your mobile phone the police will not respond if you call them, even if you have audio or visual evidence of a break-in. They will attend only after eyewitness confirmation that a burglary is taking place.
A monitored system is a more expensive alternative to an audible and auto-dialling system. When the alarm is triggered, a signal is sent to an alarm-receiving centre via a telephone line. The centre then contacts nominated keyholders and the police who will respond subject to confirmation procedures.
Monitoring systems are therefore more expensive due to the involvement of a third party. These types of system involve a contract and a monthly fee which is subject to regular maintenance of the alarm system to minimize false alarms. In addition, installation these types of systems must be subject to conditions stipulated by the police, such as British Standards and a call-out will be conditional on the number of false alarms within any 12 month period.
While these conditions specified by the police may seem strict, it is important to note that in excess of 92% of all alarm activations nationally are false alarms due to faulty equipment or user error. DIY wireless alarms in particular are associated with high numbers of false alarms. Professional installations of alarm systems are guaranteed by the installers and are less prone to false alarms.
Manufacturers of wireless systems have worked hard in recent years to change perceptions about these products and there are now some very good systems available in this segment of the market. It is worth buying the most expensive system you can afford to ensure the quality of the hardware. This will minimise the chance of a false alarm due to faulty equipment. In addition, it might be worth paying an electrician to install it for you.
