With a combination of onboard functions and OpenStreetMap (OSM) data, unsurv offline helps you to collect and analyze location data in a privacy-friendly way. This completely open source project was originally designed to better understand offline video surveillance and to help you find and develop a wide variety of custom use cases. “
“To visualize the growing video surveillance network, this device can generate a daily report of your close encounters with surveillance cameras without revealing your location to third parties. This is done by using a database of camera locations from the OSM on the SD card. For more information on this use case, check out our demo above.
You can conveniently access your unsurv data with your smartphone (or any NFC-Tag-4-enabled reader) and the dynamic NFC-Tag integrated into the case. A tiny BMA400 accelerometer helps you conserve valuable battery capacity by managing power saving features. It can even be adapted as an input device with tip and double-tap recognition or as a fitness tracker with a step counter and running / walking recognition. “
