Some of the more popular burglar alarm systems are as follows:
1. Single premises alarm systems: These are meant to warn customers about specific dangers. They include battery operated door wedge alarms, carbon monoxide alarms, smoke detectors etc.
2. Local Alarm Systems: These are designed to sound a siren to warn homeowners about the presence of an intruder.
3. Telephone Dialer Systems: These are designed to dial a pre-programmed number if an alarm is triggered. Usually these systems can be programmed to call up to four numbers and play a recorded message asking for help.
4. Continuously Monitored Security systems: These are the most hi-tech and effective systems. They are also the most expensive. When an alarm is triggered, the monitoring team of the security company that has installed the alarm alerts the police.
