Verdict
Dahua TPC-SD5441-B50Z45-BM-S24 captures more pixel detail (4.1 MP vs 3.7 MP), useful for license-plate or face identification at distance. Dahua SD8A440-HNF-PA reaches further (500 m vs 300 m) — better for perimeter and parking-lot wide shots. Dahua SD8A440-HNF-PA has stronger IR illumination (500 m vs 100 m) — better for unlit corridors and night perimeter. Dahua SD8A440-HNF-PA ships a low-light / ColorVu sensor — better in mixed-light retail or city-street scenes.
Frequently asked questions
Is Dahua SD8A440-HNF-PA better than Dahua TPC-SD5441-B50Z45-BM-S24?
Dahua TPC-SD5441-B50Z45-BM-S24 captures more pixel detail (4.1 MP vs 3.7 MP), useful for license-plate or face identification at distance. Dahua SD8A440-HNF-PA reaches further (500 m vs 300 m) — better for perimeter and parking-lot wide shots. Dahua SD8A440-HNF-PA has stronger IR illumination (500 m vs 100 m) — better for unlit corridors and night perimeter. Dahua SD8A440-HNF-PA ships a low-light / ColorVu sensor — better in mixed-light retail or city-street scenes. For installation-specific advice — mounting height, tilt, obstacle shadowing, BOM and PoE budget — drop both cameras into TodAidesign and the FOV cones, DORI rings (per EN 62676-4) and cable schedule render in real time on a satellite map or imported floor plan.
What is the field of view of Dahua SD8A440-HNF-PA vs Dahua TPC-SD5441-B50Z45-BM-S24?
Dahua SD8A440-HNF-PA has a 62° horizontal FOV at 5.6-223mm. Dahua TPC-SD5441-B50Z45-BM-S24 has a 67.5° horizontal FOV at 3.95-177.75mm. Dahua covers a wider scene at the same distance; the FOV calculator on TodAidesign converts these into linear meters of coverage at any chosen target distance.
Which camera has stronger IR illumination?
Dahua SD8A440-HNF-PA reaches 500 m of IR illumination versus 100 m for Dahua TPC-SD5441-B50Z45-BM-S24. The further-reaching IR camera is the better fit for unlit yards, parking perimeters and warehouses without permanent lighting.
Can I plan a project mixing Dahua and Dahua cameras?
Yes. TodAidesign is multi-vendor by design — drop Dahua and Dahua cameras on the same canvas, share the same EN 62676-4 lens math and DORI ring overlays, and consolidate them into one BOM with cable schedule and PoE budget. Vendor design tools (Axis Site Designer, Hikvision HiTools, Dahua Project Design Tool, i-PRO SDT) cannot do this because each speaks only its own catalog.
