Question 1

What is a Laser?

Accepted Answer

The word "laser" is actually an acronym for "Light amplification by stimulated emission of radiation". Essentially, a laser concentrates light to create a straight and bright beam. Lasers have multiple uses, including hair removal, eye repair, and cutting. Nowadays, some dentists even use lasers instead of drills when filling small cavities. And as we are discussing in this post, they can also be a huge part of home security.

Question 2

How Are Lasers Used in Home Security?

Accepted Answer

1. [Laser tripwire](https://www.covesmart.com/blog/trip-wire-alarm)**: You may already be familiar with this concept, but a tripwire is a wire that is stretched taut across a path and triggers an alarm when it is disturbed. Laser tripwires follow a similar concept. 
2. Laser fence**: Laser fences are essentially big nets of laser tripwires. They are set up all the way around the perimeter of a home. Having a laser fence ensures that you are notified whenever someone breaks through the perimeter of your home. Depending on the strength and concentration of the lasers, a laser fence can actually cause physical damage to someone who tries to cross it.

Question 3

What is Homemade Laser Security?

Accepted Answer

There are also some fairly easy do-it-yourself alarm systems that you can put up just about anywhere. YouTube is full of DIY project tutorials on how to make simple security systems out of a laser pointer.

Question 4

Can Lasers Hurt You?

Accepted Answer

The short answer to this question is: it depends. It depends on the strength of the laser and where the laser is being directed. Lasers used in surgeries and other medical procedures are much stronger, and therefore much more dangerous than the lasers used in pointers and for security. Because the light is so concentrated, many lasers generate a good amount of heat.

Question 5

Should You Get a Laser Security System?

Accepted Answer

You might consider purchasing a security system with lasers incorporated for any of the following reasons:

* You are protecting a particularly important or valuable item that is on display. 
* You want an invisible perimeter. If you are hoping to protect your home, honestly, a fence or big wall can be a great deterrent to burglars. But if you do not want a large fence, a laser system can serve you well. It can’t physically prevent someone from crossing your perimeter, but it will notify you if someone does.

* You are protecting your area. Simple laser pointer security systems are used by many people in apartments and offices. A laser alarm is a great way to alert yourself when your boss is approaching your office. A homemade laser system is also a great way to keep your roommates out of your food, or at least catch them in the act of taking it.

Question 6

What are Other Parts of Home Security Systems?

Accepted Answer

Lasers are not the only important components of a home security system, and in fact, many security systems are really effective without lasers.
