This demo walks through the core features of the BrickStor High‑Speed Data Recorder (HDR), showing how easy it is to record, playback and export a recording. Using a five‑minute test pattern with 229 multicast UDP channels, we explore how HDR manages multi‑gigabit recording and playback, distributes data across NVMe storage pools, and verifies packet integrity in real time. This capability can be used to record data from the network, RF sensors, and radars.
