RealSense close-range detection has been significantly improved. The D401/D405 now supports minimum depths down to 2 cm, while the D43x/45x series reaches 12 cm, a meaningful improvement for manipulation, inspection, and proximity sensing use cases. The update integrates transparently into the existing SDK pipeline, runs natively on D500 series hardware, and requires an NVIDIA Jetson host for D400 series deployments.
