Estos sistemas impulsados por IA pueden identificar objetos, detectar anomalías e incluso predecir incidentes antes de que ocurran. Por ejemplo, las cámaras de tráfico inteligentes utilizan redes neuronales para distinguir entre vehículos, ciclistas y peatones, lo que permite una gestión del tráfico adaptativa. Se proyecta que los envíos de cámaras de sistemas de transporte inteligente (ITS) basados en IA crecerán de 33,000 en 2020 a más de 155,000 para 2025, reflejando la rápida adopción de esta tecnología.
5G et Edge Computing : Pour maximiser la réactivité, les modules de caméra sont de plus en plus associés à la connectivité 5G et aux passerelles de edge computing. Cette combinaison réduit la latence de secondes à millisecondes, permettant une action en temps réel sur les insights. Dans la gestion du trafic, les passerelles de edge computing traitent les données des caméras localement pour ajuster instantanément les feux de circulation, optimisant ainsi le flux et réduisant la congestion. Le marché des modules IoT 5G, qui permet cette connectivité, devrait croître à un TCAC de 35,9 % de 2025 à 2030, soutenant ainsi davantage l'infrastructure des villes intelligentes.
Key Applications Transforming Urban Life
Camera modules enable a diverse range of smart city applications, each addressing specific urban challenges while creating more livable environments.
1. Gestión del Tráfico y Optimización de la Movilidad
Traffic congestion costs cities billions annually in lost productivity and increased emissions. AI-powered camera modules are tackling this issue by providing granular, real-time traffic data. In Singapore, cameras integrated with IoT sensors and analytics platforms anticipate congestion, adjusting traffic signals dynamically and reducing travel times by informing drivers through apps and signage. Similarly, adaptive traffic lights in cities worldwide use camera data to prioritize emergency vehicles, reduce idling, and optimize parking access.
The impact is measurable: the smart traffic camera market is projected to grow from 13.52 billion in 2024 to 15.47 billion in 2025, with a 15.6% CAGR through 2029, driven by demand for data-driven mobility solutions . These systems not only improve commutes but also support sustainable transportation by promoting public transit usage through real-time passenger flow monitoring.
