We’ve had issues with trespassers and thieves attacking our desert garden. As much as I dislike surveillance, I must concede to the power of having 24/7 access to a live-stream of your property when you are not there.

Originally, I wanted to build my own security camera and motion detection system using IoT components. Because of “The Shortage,” a lot of the build requirements were either unavailable or highly expensive. This is why I decided to choose a middle way: hacking together an electric system in order to install consumer-grade security cameras.


Here are the components I’m using:

  • Eufy Doorbell (Battery)
  • Eufy Doorbell (Wired)
  • T-Mobile WiFi
  • Jackery 1500 (Portable Generator and 4 Solar Panels)

Why both a Battery Camera and a Wired Camera?

I’m testing out the longevity of both. In a year’s time (2023), I’ll update this tutorial with my findings.

Why Eufy?

I chose Eufy because it provides immediate access to your footage without a monthly subscription fee. Originally, I was going to use a 5G camera that connects directly to a mobile provider. In the end, I decided to go with Eufy because their security measures seem a lot more secure than the 5G security cameras on the market (as of 2022).

Why T-Mobile WiFi?

Because Eufy requires a 2.4 GHz WiFi connection, I also purchased a T-Mobile Home Internet tower. You can use whichever mobile service provider works best in your area. Of course, this requires a monthly fee. I am okay with purchasing an internet subscription since we will be able to use this beyond the cameras.

Location Setup: WiFi Tower and Portable Generator

The first step is to decide where you want to place your power source and…
