Haven for Android allows you to transform an old or extra phone into a motion/light/sound/vibration security sensor that can detect intruders.This security app is for those that want a simple way to protect all manner of space and possessions without compromising privacy. This app leverages on-device sensors for monitoring purposes allowing it to stand silent guard for any unexpected guests and unwanted intruders. The creators designed it for investigative journalists, human rights defenders, etc., but can be used by regular users as well. For example, place a Haven-enabled phone on your laptop that is sitting on your desk at work, any movement (like the opening of your laptop) would trigger Haven to log the event. Safety through sensors - Haven only saves images and sound when triggered by motion or volume, and stores everything locally on the device. You can position the device's camera to capture visible motion, or set your phone somewhere discreet to just listen for noises. Get secure notifications of intrusion events instantly and access the logs remotely or anytime later.The following sensors are monitored for a measurable change, and then recorded to an event log on the device:- Accelerometer: phone's motion and vibration- Camera: motion in the phone's visible surroundings from front or back camera- Microphone: noises in the environment- Light: change in light from ambient light sensor- Power: detect device being unplugged or power loss
