Verdict
Uniview IPC252ERA-X22DUG captures more pixel detail (2.1 MP vs 0.3 MP), useful for license-plate or face identification at distance. Dahua TPC-BF3221P-T reaches further (300 m vs 200 m) — better for perimeter and parking-lot wide shots. Uniview IPC252ERA-X22DUG has stronger IR illumination (200 m vs 30 m) — better for unlit corridors and night perimeter. Uniview IPC252ERA-X22DUG ships a low-light / ColorVu sensor — better in mixed-light retail or city-street scenes.
Frequently asked questions
Is Dahua TPC-BF3221P-T better than Uniview IPC252ERA-X22DUG?
Uniview IPC252ERA-X22DUG captures more pixel detail (2.1 MP vs 0.3 MP), useful for license-plate or face identification at distance. Dahua TPC-BF3221P-T reaches further (300 m vs 200 m) — better for perimeter and parking-lot wide shots. Uniview IPC252ERA-X22DUG has stronger IR illumination (200 m vs 30 m) — better for unlit corridors and night perimeter. Uniview IPC252ERA-X22DUG 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 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 TPC-BF3221P-T vs Uniview IPC252ERA-X22DUG?
Dahua TPC-BF3221P-T has a 60° horizontal FOV at 7mm. Uniview IPC252ERA-X22DUG has a 60° horizontal FOV at 6.5-143mm. Both cover the same angular scene; the FOV calculator on CCTVplanner converts these into linear meters of coverage at any chosen target distance.
Which camera has stronger IR illumination?
Uniview IPC252ERA-X22DUG reaches 200 m of IR illumination versus 30 m for Dahua TPC-BF3221P-T. 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 Uniview cameras?
Yes. CCTVplanner is multi-vendor by design — drop Dahua and Uniview 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.
