The best type of alarm for your home depends on your personal preferences, budget, where you live, what your home is like and what level of protection you need.
A key consideration is what you would prefer to happen when your alarm goes off. Bells-only alarms make a noise, but do not contact anyone (such as the police or the homeowner). Speech diallers, a device built inside an alarm, automatically contacts you or other nominated friends and family when the alarm is triggered. Alternatively, you could get a monitoring contract, whereby to take action or call the police if the alarm goes off.
