Verdict
Dahua SD49225DB-HNY captures more pixel detail (2.1 MP vs 0.1 MP), useful for license-plate or face identification at distance. Hikvision DS-2TD4137-50/WY reaches further (2200 m vs 100 m) — better for perimeter and parking-lot wide shots. Hikvision DS-2TD4137-50/WY has stronger IR illumination (200 m vs 100 m) — better for unlit corridors and night perimeter. Dahua SD49225DB-HNY ships a low-light / ColorVu sensor — better in mixed-light retail or city-street scenes.
Frequently asked questions
Is Hikvision DS-2TD4137-50/WY better than Dahua SD49225DB-HNY?
Dahua SD49225DB-HNY captures more pixel detail (2.1 MP vs 0.1 MP), useful for license-plate or face identification at distance. Hikvision DS-2TD4137-50/WY reaches further (2200 m vs 100 m) — better for perimeter and parking-lot wide shots. Hikvision DS-2TD4137-50/WY has stronger IR illumination (200 m vs 100 m) — better for unlit corridors and night perimeter. Dahua SD49225DB-HNY 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 Hikvision DS-2TD4137-50/WY vs Dahua SD49225DB-HNY?
Hikvision DS-2TD4137-50/WY has a 7.5° horizontal FOV at 50mm. Dahua SD49225DB-HNY has a 60° horizontal FOV at 4.8-120mm. 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?
Hikvision DS-2TD4137-50/WY reaches 200 m of IR illumination versus 100 m for Dahua SD49225DB-HNY. 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 Hikvision and Dahua cameras?
Yes. TodAidesign is multi-vendor by design — drop Hikvision 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.
