Verdict
Hikvision DS-2CD2T46G2-4I(6mm) has stronger IR illumination (100 m vs 80 m) — better for unlit corridors and night perimeter. Hikvision DS-2CD2T46G2-4I(6mm) ships a low-light / ColorVu sensor — better in mixed-light retail or city-street scenes.
Frequently asked questions
Is Hikvision DS-2CD2T46G2-4I(6mm) better than Dahua TPC-BF5641-B5F4?
Hikvision DS-2CD2T46G2-4I(6mm) has stronger IR illumination (100 m vs 80 m) — better for unlit corridors and night perimeter. Hikvision DS-2CD2T46G2-4I(6mm) 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-2CD2T46G2-4I(6mm) vs Dahua TPC-BF5641-B5F4?
Hikvision DS-2CD2T46G2-4I(6mm) has a 53° horizontal FOV at 6mm. Dahua TPC-BF5641-B5F4 has a 87° horizontal FOV at 4mm. 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-2CD2T46G2-4I(6mm) reaches 100 m of IR illumination versus 80 m for Dahua TPC-BF5641-B5F4. 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.
