AET QC 4.81 (500×500) vs Dahua DHI-PHGOA4.81-PH

4.808 mm against 4.808 mm · specifications from both manufacturers' datasheets

Side-by-side specifications, then the same wall built from each tile, so the comparison is in panels, kilograms, circuits and data runs rather than in marketing copy.

Whole cabinets rarely hit an identical size, so each wall is the closest build to a real video format (16:9 or 16:10) near 8 m wide for that tile: 8.00 × 4.50 m and 8.00 × 5.00 m respectively.

What the numbers say

Both resolve to about the same density (43,264 and 43,264 pixels per square metre), so pick on weight, power or what your shop already owns rather than on image detail.
AET QC 4.81 (500×500) is the lighter rig: 30 kg/m² against 34 kg/m². Across this wall that is 280 kg of difference, 1,280 kg versus 1,560 kg, which moves point loads and can change the hoist call.
AET QC 4.81 (500×500) draws more: 680 W/m² against 650 W/m² at full white. For this wall that is 24.5 kW versus 26 kW, and 9 versus 10 circuits at a 16 A/230 V supply with an 80% derate.
Both come out at 4 data runs for this wall, though they carry 48 and 24 panels per port respectively.
Different cabinet formats: 500 × 500 mm against 500 × 1000 mm, so 144 tiles versus 80 for the same wall. Fewer, larger cabinets build faster; smaller ones give finer control over wall dimensions and are easier to handle alone.
Estimated truck space: 4.2 m for Dahua DHI-PHGOA4.81-PH against 5.8 m for the other, including spares, cases and cabling.
