Surveillance and tracking technologies depend on keeping people unimpeded in their daily lives and in the dark about the extend of it happening. These goals are achieved through multiple ways which will be discussed in a seperate blogpost.
To address that disconnect unsurv is developing an independent offline device to alert you when you enter the vicinity of a surveillance camera or are possibly being tracked via WiFi or Bluetooth. The device itself aims to be as passive as possible to not enable user tracking by itself.
The prototype comes with multiple components:
- the main chip is an ESP32 which features Wifi promiscous mode + Bluetooth
- for now a MPU6050 Accelerometer activates an energy saving state when the device is not being moved
- the ublox SAM-M8Q is a compact GPS, Galileo, GLONASS receiver for getting the device location
- a Texas Instruments RF430CL330H NFC Transponder + antenna for hard to detect communication with a smartphone
- a SD-Card reader for configuration and a database of cameras in the area
- a standard lithium battery with onboard charging via micro USB
You can follow the development and have a look at the hardware design on GitHub.
