Source note
The document states one control range for both modes (1.3 million pixels) and no per-port capacity. The document contradicts itself on size: the dimension drawing shows 248.00 × 132.15 × 42.20 mm, the parameters table prints 287mm×140.3mm×42.3mm; the drawing is recorded in capabilities and both are kept in specs. 4G/5G is an optional module. The document does not state an output frame rate; 60fps appears only in the video decoding table.
