An old Android phone is the ultimate security camera for homelabbers—here’s how I set up mine

Old Android phones and tablets make better security cameras than cheap IP cameras. You’ll find a lot of apps designed for repurposing phones into live security cams. The apps generate a live stream that you can view inside a browser. However, you can also hook it up to a network video recorder to record or re-stream the feed from the Android device. That way it can seamlessly integrate into your existing security system.
