I use 6 of my old smartphones to keep an eye on my home. One for my disabled wife, one for our exotic birds, one in a window to watch our cars, one in the kitchen to monitor the back door, one in the french doors to monitor our patio and one in the bathroom(it doesn’t see the entire room mostly the ceiling) my wife uses in case she needs help. I’ve used Alfred for over six years. It has worked very well for my needs.

The absolute easiest security app ever to set up super simple super easy. When you’re a single mom it doesn’t get any better than that. Had an old phone laying around downloaded the app on both and Bam ???? that’s it literally that’s it. I can make sure my house is okay as well as my kids are safe.

Placement Pro Tips: How to Place a Cell Phone Security Camera?

To get the most out of security camera devices, placement is everything. The same applies to old phones turned into security cameras.

Here’s how to optimize your phone security camera placement.

  1. Maximize visibility by using corners and other dark spaces. Light needs to be on the subject, not the camera.
  2. If using Wi-Fi, maintain a through-line between the camera device and the Wi-Fi router to keep the connection stable. Stay as close to the router as possible.
  3. Use vertical space to reduce blindspots. Tilt security cameras down toward their subject from several meters high.
  4. Try recording while charging. While you don’t need to have the phone plugged in constantly to use it as a security camera, you don’t need to turn it off if you choose to charge periodically, either.
  5. Experiment with device mounting using sticky tape. An advantage of using phones as security cameras is that there’s great flexibility in where it can go.
