50 matched panels · 1.25 to 10 mm · specifications from both makers' datasheets
The two lineups side by side, then what the matched panels say about weight, power and what each maker publishes. Every figure is the maker's own; the planner adds nothing it cannot point to on a sheet.

Weight and draw are per square metre of cabinet, so different cabinet sizes compare fairly. Ranges run across every panel the maker has in the database, not only the matched ones.
What the sheets say
Dahua and Desay overlap on 50 matched pairs between 1.25 and 10 mm; outside that band one of them has no comparable panel.
Dahua is the lighter cabinet in 49 of 50 matched pairs, Desay in 1. Across their lineups that is 19 to 36 kg/m² against 22 to 44 kg/m².
Dahua draws less at full white in 40 of 50 matched pairs, Desay in -1, and 11 are within 5%. Lineups: 331 to 680 W/m² against 531 to 760 W/m², which sets the circuit count.
Cabinet formats: Dahua builds in 600×337.5, 500×500, 640×480, 1000×500, 500×1000, 960×960 mm; Desay in 500×500, 800×900 mm. A shop that already owns one format keeps its bumpers and cases.
A hanging limit is published for none of its 57 panels by Dahua and for none of its 18 panels by Desay; where it is not, the planner uses a conservative placeholder and says so.
Both publish a typical draw for every panel here, so the typical kilowatt figure rests on the sheets, not on an estimate.
Matched panels, side by side
Each pair is two panels of comparable pitch, one from each maker, with the same wall built from both.
