Verdict
Dahua SD8A840-HNF-PA captures more pixel detail (8.3 MP vs 8.2 MP), useful for license-plate or face identification at distance. Dahua SD8A840-HNF-PA has stronger IR illumination (500 m vs 70 m) — better for unlit corridors and night perimeter.
Frequently asked questions
Is Dahua SD8A840-HNF-PA better than Dahua SDT3E410-8P-MB-A-PV1?
Dahua SD8A840-HNF-PA captures more pixel detail (8.3 MP vs 8.2 MP), useful for license-plate or face identification at distance. Dahua SD8A840-HNF-PA has stronger IR illumination (500 m vs 70 m) — better for unlit corridors and night perimeter. For installation-specific advice — mounting height, tilt, obstacle shadowing, BOM and PoE budget — drop both cameras into CCTVplanner 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 SD8A840-HNF-PA vs Dahua SDT3E410-8P-MB-A-PV1?
Dahua SD8A840-HNF-PA has a 64° horizontal FOV at 5.6-223mm. Dahua SDT3E410-8P-MB-A-PV1 has a 180° horizontal FOV at 4-40mm. Dahua covers a wider scene at the same distance; the FOV calculator on CCTVplanner converts these into linear meters of coverage at any chosen target distance.
Which camera has stronger IR illumination?
Dahua SD8A840-HNF-PA reaches 500 m of IR illumination versus 70 m for Dahua SDT3E410-8P-MB-A-PV1. 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. CCTVplanner 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.
