Modern cities demand smart traffic management systems capable of responding to congestion, accidents, and real-time fluctuations in vehicle flow. Traditional methods rely on costly embedded infrastructure, fiber optic networks, or manual monitoring \u2014 all of which lack scalability and instant accessibility. With the emergence of IoT and edge computing, a new era of camera-to-cloud traffic density monitoring<\/strong> has begun.<\/p>\n\n\n\n

To enhance connectivity in these systems, many developers now use Raspberry Pi 4G LTE CAT4 HAT with Quectel EC200A for high-speed video transmission and Raspberry Pi 4G LTE CAT 1 HAT with Quectel EC200U for low-power, metadata-driven deployments.<\/p>\n\n\n\n
