By Alberto Garcia and Andrea Lopez-Villafana The San Diego City Council last week approved a $30.2 million project that will retrofit 14,000 street lights to LED units, but the program also includes 3,200 surveillance camera and microphone units that were discreetly referred to as “sensor nodes.” The project has been described as the world’s largest smart city Internet of Things (IoT) sensor platform. During presentations at the City’s Infrastructure Committee on June 29, as well as before the full City Council on July 17, city staff from the Environmental Services Department described the project as an “Intelligent Cities Outdoor Lighting Program” with the stated goal of supporting the City’s Climate Action Plan.
