How Does it Work?

There are several components that may be used in a infrared security system. For generalization purposes, this article will cover the most common features. This includes:

Circuit Board
The circuit board for a infrare security system usually includes a microchip, a voltage regulator, a battery, a resistor and a photo cell. It's possible to make your own circuit board for a laser security system, as long as you have access to the proper tools and materials.

Pet Immunity
Since infrared are so easily triggered, many infrared security systems also include a pet immune feature. If your system does not have pet immunity, you may want to place your laser security system at a height where it will not accidentally cause your pets to trigger the alarm.

Audible Alarm
As a deterrent, a laser security system may include an audible alarm. This alarm will be triggered when the infrared beams is broken, signaling that the system detected movement.


Text Message Alerts
When a infrared security system detects movement inside your home, it may be able to send you a text message alert. This can be done even if you have built the system yourself, as long as you have a fair bit of electrical knowledge.
