5 Ways to Use Your Old Android Phone as a Free Security Tool in 2026

Got an old Android phone sitting in a drawer? Don't let it collect dust — turn it into a powerful security tool.

Here are 5 creative ways to repurpose your old Android device:

1. Home Security Camera

Install a background recording app like Background Camera RemoteStream and mount your phone near your front door. With screen-off recording, your phone uses minimal battery (8-12 hours) while continuously capturing video.

2. Dashcam

Mount your old phone on your car dashboard. Background Camera RemoteStream records even with the screen off, so you won't drain your battery or get distracted by a lit screen while driving.

3. Baby Monitor

Place your old phone in the nursery. With YouTube Live streaming built into Background Camera RemoteStream, you can watch the feed from any device with a browser — no special app needed on the viewing end.

4. Pet Cam

Keep an eye on your furry friends while you're at work. Set up your old phone pointed at your pet's favorite spot and stream to YouTube Live for real-time monitoring.

5. Wildlife Camera

Place your phone near a bird feeder or wildlife trail. The long battery life with screen-off recording makes it perfect for extended nature observation sessions.


Background Camera RemoteStream is free on Google Play. It's the only Android app that combines screen-off video recording with YouTube Live streaming.
