It is important to find the best home security system which is certified by the state or reputed institution.
While selecting an Arcadia home security system, the vital factor is reliability. If the system is out of action for even a short time that could be the very time the intruder strikes. Reliability is dependent on first, the control unit, its design, construction and quality of components and second, on the installation, its wiring and ancillary equipment including the sounding device. The reliability of the control unit cannot be assessed by a potential user.
It would require experience of a large number of the same model to determine, something that only the large installation companies would have. If there is a poor record of reliability for any particular model it is unlikely they would continue to stock or supply it. A model that has been on the market for some while and is still readily available from several firms is thus likely to be a better risk than a new one, however attractive its features may be.
Actually, all electronic components are liable to failure, and a failure rate per thousand samples plus a mean time to expected failure is assessed by exhaustive testing and is specified by component manufacturers. There is an American Standard that defines methods of expressing failure rates.
This shows that 100 per cent reliability for components is unattainable and any claims for such should be treated with the utmost skepticism. It follows from this that the more components the control unit has and the more complex it is, the more likely, statistically, it is to fail. Complex units having many features are now offered at quite reasonable prices compared to what they were at one time. This is partly due to the use of dedicated (specially designed) silicon chips which carry out most of the functions. However, a host of features you will never use could be obtained at the cost of higher liability to failure.
This is not to say that the present generation of alarm units is basically unreliable, only that the chances of a breakdown are greater with a more complex unit. Having made this point it should be said that the most likely cause of a fault is in the installation, in the wiring, sensors, or in the use of unsuitable sensors. One of the biggest problems with alarm systems is that of the false alarm. In the Metropolitan police area no less than 98 per cent of the call-outs are for false alarms. Understandably the police see this as a considerable waste of their time and resources and some forces have been forced to lay down conditions as to how far they will respond. It is important to find the best Arcadia home security systems which come with advanced features and the one which doesn’t make false alarm.
