A security system consists of a key pad, usually located near the entrance of the home and alarms that will sound when there is an alert. You arm the alarm by pushing a button. If you are leaving home, you will have a few seconds to leave before the alarm is fully functioning. If re-entering, you will have a few seconds to disarm the alarm by entering a pass code.
A security system works by a variety of different means or a combination of them. Contacts placed on doors and windows will detect when they are opened. When you are not in the home, use of motion sensors can be helpful. Your home should not have activity when you are gone, so any motion detected will signal an alarm because it is assumed there is activity where there should not be any. Glass breakage detectors will sound if an intruder forcibly breaks a window or door in your home.
A combination of these sensors is recommended for maximum protection and security. Motion sensors alone may not provide adequate security and only work after someone has already entered the premises. These may also get triggered by active pets, causing a false alarm. Most alarm systems will allow you to remove this option when you are inside the house so anyone awakening during the night will not accidentally set off the system. Another good feature to have is a panic setting. These will allow you to immediately set the alarm off in case of an intruder. A special code is often assigned for cases of kidnapping or forced entry. If a criminal forces you to disarm the alarm, you can put in the special code. This will send a silent alarm to the police, alerting them of a possible hostage incident. No alarm will sound but police will be dispatched.
For maximum security, monitored alarms should be used. This will alert police when the alarm sounds. Generally a callback will be made to determine if there is an actual problem before dispatching authorities. If nobody answers or the secret word that was assigned is not used, police will then be dispatched to investigate. Monitoring is done on a monthly basis for a small fee. It also usually requires an annual permit that can be obtained inexpensively. False alarms where police are dispatched may be charged to the customer for needlessly sending out authorities, so be sure to call the monitoring company if there is a false alarm.
Using a home security system will provide comfort to the family. Knowing you, your family, and your possessions are secure from theft and break-ins is invaluable. Security systems are inexpensive yet provide a valuable sense of security.
