How to Build DIY Home Security Systems with SMS

Building a DIY home security system is one of the best ways to utilize technology well. The best part is that you don’t have to be a tech wizard to do so. Also, with a few tweaks to the software, you can even create your home security system that can send you an SMS authentication the moment it detects any motion. That said, here are some DIY systems you can try out:

Webcam Security System 101

To set up a basic home security system, you have to own at least a personal computer or laptop with a built-in webcam. If you want better and more effective coverage of your space, you may use a USB webcam or a wireless IP cam. You will also need to download iSpy Connect, a free software that will help you use your computer or webcam as a security camera that can detect movements.

The iSpy Connect is compatible with most built-in cameras, USB webcams, and IP cams. Once you are done setting up the cameras and software, you can now add a motion detection function. Choose specific areas of the camera’s range of view and input on iSpy how much motion will get to trigger the alarm.

Another software that you may want to consider is Sighthound. Its basic version can be downloaded freely. However, after a 14-day trial period, you will be required to purchase its Pro version. Just like iSpy, Sighthound is also capable of notifying or alarming you of any motion around your chosen space.

The Arduino Motion Detector

The Arduino motion detector is one of the most known motion detectors in the market. It is plainly simple yet is the most effective SMS-based security system. Through specific codes which are given by Python libraries and TelAPI, an online communication service, the Arduino motion detector can send you an SMS once motion has been detected. It can’t provide you with an image of who did the motion as a webcam does, but if you are only after a simple system, then this is your best option.

Add a Little Color

Congratulations! You have now created your DIY home security system. After that, you might want to add a little color to make it more fun give it a cool vibe? To do so, you may connect your home security system to a smart light system.

You can set up your iSpy Connect to send a notification like an email that can turn on your lights or even let them change color for more advanced lighting systems. You can also utilize TelAPI to send an email to IFTTT and do other actions like turn on the radio through any smart things system.

With Arduino, there are lots of tutorials online on how to connect it to an alarm system that can open LED lights or set off an alarm combined with sending an SMS to you.


There are countless ways to build DIY home security systems. Software like iSpy Connect, Sighthound, Arduino, and TelAPI are just some of the few. With the right amount of knowledge combined with a few tools, you can reach your goal to a safer environment for you and your family.
