Overview
CCTV has moved from simple analogue recording to digital IP surveillance with real-time image analysis.
Modern cameras use WDR, infrared illumination and low-light sensors to maintain usable image quality in difficult conditions.
Video analytics and deep learning can classify people and vehicles, detect line crossing, support perimeter protection and reduce unnecessary recording through efficient H.265+ compression.
Technical point: Modern CCTV systems record, analyse and classify events in real time.
