Home Security

Welcome to HomeAndPersonalSecurity.com. This spring, dig into considering the items and behaviors that will help keep your property and family safe. Our online home security system store has everything you need to feel safe in your own home, plus plenty of informational articles about home and family safety tips.

Home is supposed to be a safe place, but we’re often bombarded with news stories which indicate that this is not the case. Break-ins, burglaries and kidnappings seem to dominate the media–putting us in a state of irrational fear. Even though our world is not nearly as dangerous as the nightly news would like us to believe, there is nothing more valuable than peace of mind. Feeling safe is invaluable and knowing that your family and possessions are safe is even better. If a home security system gives you that feeling of safety, then we say go for it! Hopefully our home security system store will provide some information on the best home security systems, personal alarms and security cameras.

Besides an irritable dog, burglar alarms are the most common instruments of home security. As their name states, these alarms are meant to detect when any intruder enters the house. The simplest alarm consists of an open or closed circuit, which is often placed at an entrance. Remember when you learned about electricity in grade school–about how disrupting an electrical current will turn a light off? Well, circuit alarms work in the same way: there is an electric current that runs between objects (in this case, the frame and the door). When that flow is disrupted or stopped (someone opening the door), it sets off an alarm.

The problem with circuit alarms, however, is that it relies on specific behavior from intruders. How do you know that they wouldn’t enter somewhere else–somewhere that’s not protected? Technologic advances have made motion detectors the most popular (and reasonably-priced) option for home security.

Radar-based motion detection is the most popular form of detection in security systems, which we also see in our everyday lives. Automatic doors, used frequently in grocery stores and shopping malls, run on radar-based motion detection. During the process, a box shoots microwave radio energy over an area at regular intervals and then waits for the reflected energy to signal back. If there the signal returns faster than normal–or, if a person is in the way of the energy–then the signal difference will trigger an alarm (or cause those automatic doors to open).

The most advanced form of motion detecting is called passive infrared (PIR). These detectors are called passive because they don’t need to generate their own energy; a radar detector has to constantly emit microwaves. Rather, PIRs operate by “seeing” the infrared energy of the room. For example, if an intruder inters the room, the PIR will detect the rapid change of heat in the room and sound the alarm.

Light/laser sensors work similarly to circuit-based detectors: if the light beam is disrupted or doesn’t reach its destination, an alarm will sound. These detectors are common in movies where a character has to maneuver through beams of light to foil security. When a security device is triggered, it will emit loud sounds, flash lights, and an auto-dialer will inform either a security agency or the police. It’s also possible to combine all these detecting techniques for full and complete personal security.
