The Home Security Alarm is becoming more common for folks seeking home defense.
Protecting one's home in the old days used to be as simple as locking a few doors and windows.
But nowadays, something a little more sophisticated is in order.
While no system completely fool proof, they do offer defense against would be intruders.
Security systems generally use different types of sensors to detect an intruder.
When active, they will go off if someone trips those sensors.
The most basic alarm will make a lot of noise, which is usually more than enough to scare off a burglar.
Some of the more advanced units, however, can send a signal to police or your provider when the alarm is triggered.
Obviously, the you're not going to want to wake the neighbors every time the come and go, so the security system has a control box that allows you to arm or disarm it as needed.
A password is often used to bring it online or offline.
There are a few different types of detectors.
These include Infrared, Ultrasonic, Microwave, and Photoelectric.
Each type of sensor is placed within the house where an intruder is most likely to enter or try to reach.
Infrared detectors rely on temperature.
They pick up on changes in heat in the area.
Since we all generate body heat, anyone who enters for any length of time is detected.
Ultrasonic detectors send out a high pitched sound that can't be heard by people.
They measure the sound frequency in the room and notice changes.
If something moves, the frequency is affected and it goes off.
Microwave detectors work much the same way as ultrasonic does, except that it uses microwaves instead of sound waves.
If something moves and changes its frequency, the alarm is tripped.
Photoelectric detectors are basically trip wires made of light.
Beams of infrared light are placed in the room and if the light is broken, the alarm goes off.
Some systems are invisible while others aren't.
They will detect someone, but only if they're tripped.
If a burglar manages to avoid them, they can move around unnoticed.
Deciding which security system to use is entirely up to the consumer, depending on their needs.
The most basic models can be installed on your own.
But if you don't know much about them or you're concerned about how to go about it, there are professionals who can set it up for you.
