Don’t Trash Your Old Phone, Use it as a Security Camera!


So you’ve got some old smartphones laying around in house, in closets, sock drawers, etc., don’t just let them sit there doing noting gathering dust. There are so many uses for old cellphones we’d be here all day just scratching the surface.

Well, for example an older cellphone could be used as fileserver or as a smart assistant for your home – why buy a brand new one from Amazon? But for my money the most intriguing use for a retired smartphone is as a security Camera.

A cellphone as security camera, let’s do it

If you’re looking for a low-cost, DIY way to keep an eye on your home, an old smartphone can be an effective security camera. With just a few minutes of set up, you can turn your old device into a full-fledged security system without spending a dime. Here’s how to do it.

  1. Get the right app.

The first step to turning your old phone into a security camera is downloading the right app. There are several good ones out there, with features like motion detection and cloud storage. Most are free, though some allow for the purchase of in-app add-ons. We recommend Alfred, Presence, or Salient Eye.

  1. Set up the motion detector.

Once you’ve downloaded your chosen app, you’ll need to set up the motion detector. Depending on the app, this may involve inputting your home’s Wi-Fi password, or setting up a specific motion-detection area. The app will then be able to detect movement and alert you of any suspicious activity.

The next step is to install the app on your old phone. Make sure you’re using an up-to-date version of the app, as some older versions may be incompatible or have fewer features.

  1. Mount the phone.

Once the app is installed, you’ll need to mount the phone in a secure, central location. If you’re using a tripod or a stand, make sure to secure it firmly. You may want to mount the phone near a window in order to get the best view of the area you want to monitor.

  1. Test the system.

Once you’ve mounted the phone, it’s time to test the system. Start by walking around the area you want to monitor and make sure the motion detector is working correctly. If everything looks good, you’re ready to start using your old phone as a security camera.


Using an old phone as a security camera is a great way to keep an eye on your home without spending a fortune. With the right app and a few minutes of setup, you can have an effective security system up and running in no time.
