What Alarm System is best?

May 25, 2014

During research interviews by criminologists over the years most burglars (who expressed a preference) said that they were definitely put off by alarms!  Although I personally believe that a monitored alarm is an excellent deterrent in its own right everybody, including the police and your insurers, will expect you to also achieve a minimum level of physical security as well.  In fact everybody will tell you to sort out the physical security first and only afterwards put the alarm in.  So be very aware that if you do have a top of the charts, bells and whistle alarm system in place and you get burgled and it’s discovered that you don’t have the right lock on your front door, your insurers may refuse to pay your claim. 


The basics
'Wired' and 'Wireless' alarms

There are two types of intruder or burglar alarm systems: 

Wired alarms comprise a number of electronic sensors that are connected to a control panel by low-voltage wiring and are governed by the AS/NZ series of standards.  These are installed into new homes and into existing homes during refurbishment as it is more convenient to run the wiring at these times.

Wireless alarms as the word suggests, use battery powered sensors that are ‘connected’ to a control panel by narrowband RF signals (radio signals). These are quick to install and are used for homes where you don’t want to disturb the decor or have to run new cabling. The only minor downside is that the sensor batteries have to be changed from time to time ( Around every 3 years)

When the sensor is triggered (by sound or a change of temperature, such as that caused by somebody moving in front of a sensor) the sensor will send a signal to the control panel. The control panel will then activate an internal and or external audible and visual alarm. 

If the alarm is the type that can send a signal to a remote alarm receiving centre (ARC) it will do so and the ARC will carry out your instructions to inform a range of people, such as a professional keyholding service, you, or another keyholder.  Once the ARC has received a confirmation signal from the alarm system the ARC will inform the police if that is what you have arranged for.

Most alarm systems generally have the same features and the end results are basically all the same.

So in the end it comes down to who you want to install your Home Security System.
