Source note
Compiled from the HD-B8H specification V1.0 (Jun 29, 2026). maxLoadingPixels is the single-unit figure (2.6 million); the 8.8 million figure applies to a cascaded configuration of several units and is kept in specs. The document prints no per-port capacity, no operating power consumption (only standby power) and no weight. 4G/5G needs the optional module, so cellular4G is left null. The TTL port accepts external sensors or GPS devices; no built-in GPS is stated. The features page calls the output targets "HD capture cards" and the interface table "HD receiver card"; both refer to the cards driven by the 4 output ports. The product is a bare board (no enclosure).
