Home security systems reviews consumer reports

Home security, while usually associated with intruder deterrents, really refers to the protection of the home and its occupants against all hazards. Good home security systems use sensors, cameras, and alarms to keep the house safe. Sharp increases in crime rates in certain communities, both urban and rural, have made home security systems quite common.

The alarm is the most important part of the home security system for the simple reason that sensors and cameras can detect threats, but it is the alarm that alerts the people to any dangers the system detects. Usually the alarm is either a sound or a light, or most effectively a combination of the two. You’ve probably encountered a lot of these types of alarms before elsewhere; it’s not uncommon for a home security system to have motion detectors, door alarms, fire alarms and more.

Home security alarms system can be as simple as a ten dollar wall-mount detector, or as complex as a thousand dollar closed circuit system. It is important not to confuse simplicity with effectiveness as the most important alarm in your house, the fire alarm, is a very simple device.

Similarly, most burglar alarms are based on the breaking of a circuit. The alarm is attached to a door or window and goes off when opened and the normal flow of electricity is interrupted. If an intruder manages to get inside the house, then motion sensors are commonly employed to alert the owners and help them track the intruder using passive infrared.

At every one of these stages, an alarm could be flashing visually, making noise, and completing automatic calls to the police. All of these actions serve the same general purpose of guiding people’s awareness to danger. When you have so many advantages at your side, you can rest assured that in the case of a true emergency you will be instantly, easily and undeniably aware of it.
