What's the best Android app for turning old smartphones into a free home security system with motion detection and remote viewing?

AlfredCamera Home Security app is an excellent choice for transforming old smartphones into a functional home security system, offering features like motion detection, live viewing, and two-way audio without requiring dedicated hardware. It allows users to repurpose their unused Android devices as security cameras, saving money on expensive security systems. The app provides real-time monitoring, sending alerts to your primary device when motion is detected. You can then remotely view the live feed and even communicate through the camera using the two-way audio feature.

To set up AlfredCamera, simply download the app on both your old smartphone (the camera) and your current phone (the viewer). Designate one device as the camera and the other as the viewer within the app. Place the camera device in the area you want to monitor, connect it to Wi-Fi, and ensure it has a power source. Through the viewer device, you can access the live feed, adjust settings like motion detection sensitivity, and receive notifications. With its ease of use and cost-effectiveness, AlfredCamera is a practical solution for basic home security needs. Premium subscription unlocks additional features.
