An Explanation Of Wireless Intruder Alarms
Security alarms used to only be installed in businesses; however with crime rising in residential areas, more and more homeowners are looking into and installing wireless intruder alarms. In the last few years, many home alarm systems have come out with features as sophisticated as ones for businesses. There are many different varieties of systems on the market today. There are both wired and wireless security systems available, but the wireless ones have become more popular the last few years.
A wireless security alarm is the type people want the most these days because of their reliability and efficiency. These alarms do not require that wires be strung throughout the house and attached to a main control panel because of the convenience of being wireless. They use radio waves that are broadcast from the individual motion detectors to the main control panel in order to monitor people going in and out of the house.
These detectors are installed at all the door entrances, exits and sometimes the windows. When an intruder tries to get into the doors or windows, an alarm goes off usually locally and also the local police department may be notified. There is also a keypad located on a wall in the residence that controls the system. Usually this keypad can be activated remotely also.
Wireless alarm systems are preferred over wired alarm systems because they are much easier to install. Since the walls and floors don’t have to be damaged by installing the wires, money can be saved and less energy used to put in the alarm. However, sometimes the wireless alarm system will cost more to purchase the equipment itself and you have to remember to change the batteries on a regular schedule. The batteries are a backup in case the power goes off in the residence. Another benefit is that if you move to another residence, it is very easy to transfer it to the new house.
Wireless alarm systems are very simple to manage. When a homeowner is about to leave the house, they key in a pass code to the control panel on the wall and then they have a certain amount of time, usually between 30 to 60 seconds, in order to leave the house and secure it before the alarm sounds. If by mistake they take too long, it is no big deal. They just go back to the control panel and key in the pass code again to stop the alarm and then start over.
While they are away, if someone enters the home, a signal goes directly to the alarm receiving centre and also a loud alarm goes off in the house. Sometimes the alarm companies, when they receive the alarm signal, will phone the owner to make sure it is not a false alarm. The reason for this is the high number of false alarms where police are dispatched to the homes unnecessarily.
Additionally, wireless intruder alarms can utilize home security cameras. The cameras are added as additional security and can also record activity in the home. These cameras can be triggered to record when motion is detected. Also, reactive infrared sensors are available that can sense body heat or motion in a certain area of the home.
