Motion Detector detects the appearance of people and optionally vehicles on the camera and takes pictures of them. Photos are visible in your device's Gallery. You can also set the app to play an alarm when a person is detected. New detection warning and image storage can be changed at different time interval.
You can also sync your other device to receive notifications when new motion is detected.
