Dahua DHI-PHSIA1.2-LS vs Desay X1.2i

1.25 mm against 1.25 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: 7.80 × 4.39 m and 8.00 × 4.50 m respectively.

What the numbers say

• Both resolve to about the same density (640,000 and 640,000 pixels per square metre), so pick on weight, power or what your shop already owns rather than on image detail.
• Dahua DHI-PHSIA1.2-LS is the lighter rig: 28 kg/m² against 44 kg/m². Across this wall that is 632 kg of difference, 1,138 kg versus 1,770 kg, which moves point loads and can change the hoist call.
• Desay X1.2i draws more: 752 W/m² against 499 W/m² at full white. For this wall that is 17.1 kW versus 27.1 kW, and 7 versus 16 circuits at a 16 A/230 V supply with an 80% derate.
• Data is lighter on Desay X1.2i: 48 runs against 52, at 4 and 3 panels per port respectively (60 Hz, 8-bit, ports loaded to 80%). Fewer runs means fewer home runs to pull and fewer processor ports to find.
• Different cabinet formats: 600 × 337.5 mm against 500 × 500 mm, so 169 tiles versus 144 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: 6.9 m for Desay X1.2i against 8.1 m for the other, including spares, cases and cabling.
