Covert surveillance capability The school loaded each student's computer with LANrev's remote activation and tracking software. This included the now-discontinued "TheftTrack".[17][25][26][27] While TheftTrack was not enabled by default on the software, the program allowed the school district to elect to activate it, and to enable whichever of TheftTrack's surveillance options the school desired.[8] The school elected to enable TheftTrack to allow school district employees to secretly and remotely activate a tiny camera webcam embedded in the student's laptop, above the laptop's screen.[17][25][26][27] That allowed school officials to secretly take photos through the webcam, of whatever was in front of it and in its line of sight, and send the photos to the school's server.[8][17] The system snapped and sent a new photo every 15 minutes when the laptop was on, and TheftTrack was activated, though school employees could adjust the timeframe to as low as one-minute intervals.[8][28][29] LANrev disabled the webcams for all other uses (e.g., students were unable to use Photo Booth or video chat), so most students mistakenly believed that their webcams did not work at all.[30] In addition, TheftTrack allowed school officials to take screenshots (pictures of whatever was on the laptop's screen), and send them to the school's server.[8][17] Furthermore, a locating device would record the laptop's Internet (IP) address, enabling district technicians to discover which city the laptop was located and its internet service provider. (A subpoena to the provider would be required to pinpoint the exact location.)
