Installing an interior motion detection system can sometimes be a expensive endeavor, but there are budget friendly alternatives available for homeowners who are a little tech savvy.
A Laser beam home security system is easy to make and even easier on your wallet. With a small soldering gun and a few components, you’ll be on your way to creating your own interior laser beam detection system. Protecting your home with laser beams is a smart and defensive way to alert you when intruders are approaching. Building a DIY home security laser system can help you rest just as easy as any top notch professional system and can work just as effectively using the same concepts.
Laser system Components
This laser system uses
a variable resistor
9 volt battery and switch
a couple of small adhesive mirrors
5 milliwatt red laser.
Make sure you also have the right AC adapter to connect to your laser. These components are mounted and then soldered together according to schematic instructions. KipKay.com offers full video step by step instructions and can help guide you by offering resources for buying parts.
After building the laser components you will then have to make sure your photocell is properly aligned with the laser. Generally, your laser is mounted at a waist high level. The mirrors get mounted on opposite walls across from your laser beam. You can extend the distance of your laser beam detector by lining up your mirrors and pointing it towards the next wall and continue adding any mirrors for as many doorways as you wish to protect. Focus on placing the mirrors near windows and entrance points around your home. Home security laser beam detectors can be practical systems to use if installed properly, especially if you’re creating a double beam system that combines more than one laser.
The laser itself is powered on a constant basis by the AC plug in adapter, but the actual photo cell receiver box is powered by a 9 volt battery. If the power goes out in your home, the laser will trip the alarm and you can just unplug it. This is the only real disadvantage of using this type of DIY system.
If you have in depth electronics knowledge, you can install a control/alarm box so that you can activate and deactivate your laser system from outside of your home. If you want to get fancy, you can also create some extra panic effect by installing a couple of green IR filtered cameras or bright diode arrays that point in all different directions at any entrance points as well.
Another great resource for purchasing parts for your laser beam system is Radio Shack. They offer hard to find accessories for a lot of home electronic projects. This system is a pretty cool project to take on if you have the time. You’ll also have the satisfaction of knowing you created it yourself in order to save money.
