Dahua DHI-PHSIA1.2-SC vs LG LSCB012

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: 7.68 × 4.32 m and 7.80 × 4.39 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-SC is the lighter rig: 21 kg/m² against 26 kg/m². Across this wall that is 209 kg of difference, 852 kg versus 1,061 kg, which moves point loads and can change the hoist call.
LG LSCB012 draws more: 741 W/m² against 400 W/m² at full white. For this wall that is 13.3 kW versus 25.4 kW, and 6 versus 13 circuits at a 16 A/230 V supply with an 80% derate.
Data is lighter on LG LSCB012: 52 runs against 60, at 2 and 4 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: 640 × 480 mm against 600 × 337.5 mm, so 108 tiles versus 169 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: 6.7 m for Dahua DHI-PHSIA1.2-SC against 8.1 m for the other, including spares, cases and cabling.
