About this app

Motion Detector turns your Android device into a motion-activated security camera. Simply tap Start to begin monitoring—when the app detects movement, it automatically records video so you never miss important moments.

KEY FEATURES
• Automatic motion detection – The app continuously monitors the camera feed and starts recording only when motion is detected, saving storage space and battery.
• Background monitoring – Keeps running in the background so you can use other apps while Motion Detector watches for activity. A notification shows whether the app is monitoring or recording.
• Flexible storage – Save recorded videos to your device’s Downloads folder or to an SD card for more capacity.
• Front and back camera support – Choose the camera that best fits your setup, whether you’re monitoring a room or an outdoor area.
• Easy video management – View, play, and delete your recorded clips from within the app. All recordings are organized in one place.
• Simple controls – Start and stop monitoring with one tap. No complicated setup required.

PERFECT FOR
• Home security when you’re away
• Monitoring pets or children
• Recording wildlife or nature
• Documenting deliveries or visitors
• Any situation where you need to know when something moves

Motion Detector uses your device’s camera and works best in well-lit environments. Grant camera, microphone, and storage permissions when prompted to enable all features.

It's a great app and works even when screen is off. I am saving two stars for future. If I was the developer, I would make following enhancements right away: 1. Provide an option to set minimum duration of no motion before it stops recording i.e. everytime motion is detected it should continue recording until there is no motion detected for the set amount of time by the user. 2. An option to save on sd card.

Doesn't work. Instead of recording a video upon motion detection, it snaps a blurry photo, then stops working all together. Even if you click "stop" and start it again, it looks like it's working, but nothing happens/saves.

I tried it out, I left it alone for about an hour and it captured the first few clips fine then just captured the next 45minutes for some reason.
