Dual-Tech Beams Infrared Motion Detector Alarm with 5-60m Distance

Product name: Dual Beams Perimeter Active Photocell Infrared Laser Beam Sensor

General Description:

How Does it Work?

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

Circuit Board
The circuit board for a laser 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 lasers are so easily triggered, many laser 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 one of the laser beams is broken, signaling that the system detected movement.

Text Message Alerts
When a laser 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.
