Intelligent Streetlight IoT Sensor Mesh

San Diego's US$30m 'CityIQ' streetlight sensor network (3,000+ nodes with cameras, mics and environmental sensors from GE Current) was deactivated in September 2020 after ACLU-raised concerns about police access to footage — only returning in 2023 under a new 5-year Ubicquia/Flock Safety agreement covering 500 cameras.

🎓 Lesson

Deploying pervasive sensing infrastructure before settling data-governance rules invites backlash that can shut the whole system down: San Diego's smart streetlights sat dark for three years after police use of the cameras came to light without public buy-in.
