Source note
Compiled from the official English specification "Smart Multimedia Controller HD-H20" V1.0 (first release Jul. 28, 2026). The document contradicts itself in three places, apparently because sentences were carried over from other documents. (1) Outputs: the overview ("20-port"), the feature list ("Twenty-way Gigabit Ethernet output"), the rear-panel picture (ports 1-20) and the SFP description ("SFP3 transmits data from ports 17 to 20") all give 20 outputs, while one row of the interface table reads "Network1~16: 16-way RJ45 output network port"; the catalog records 20 and keeps both statements as specification rows. (2) Power: the interface table and the rear-panel picture show an AC 100~240V 50/60Hz power interface, while the specification table prints "Input Power DC 5V-12V (5V 6A, 12V 3A)" with a maximum power consumption of 50W; the catalog records the AC figure and keeps both rows. (3) The interface-table row is labelled "SFP 1~2" although its text and the feature list describe three SFP ports. The document gives one loading figure (13 million pixels) and no per-Ethernet-port capacity. The 4G/5G module and the SSD are optional; GPS is an external accessory on the sensor interfaces. No PC or mobile control software is named.
