Install a home burglar alarm, improve security

The popularity of the home burglar alarm continues to grow in the US with more and more Americans installing burglar alarms to ensure the safety and security of their family and property.
Several Americans go for the simple do-it-yourself system, which can be hard-wired or wireless. In this system, the alarm goes off when an intruder breaks the electrical circuit. This triggers a siren whose noise is loud enough to wake up the entire neighborhood.
The buyer has the choice to go for an alarm system that uses an open circuit or a closed circuit. In an open circuit system, the circuit is completed when a door or window is opened, and the alarm is triggered. In a closed circuit system the opposite happens. When a door or window is opened, the circuit's connection is broken and the alarm goes off.
The more sophisticated burglar alarms use motion sensors. These sensors use infra red rays to sense movement. The change is transmitted to a control panel that analyzes the signals. If the signals are beyond the "high suspicion" levels, the alarm is triggered.
Several Americans prefer to install both motion sensors as well as electric circuit-based alarms to give added protection to their homes. The advantage of such a system is that large, open spaces like halls can be guarded better with sensors.
Many home burglar alarm systems use video cameras. These cameras are mounted at different strategic places around the house. Their job is to transmit images to a central monitor in the house for screening.
Several home security companies also provide centralized monitoring of the premises. The home owner, in this case, need not worry about security but leave it to the security company. When the alarm is triggered the security company informs the local police. In some cases it also rushes its own emergency team to help the customer.
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.
