Frequently asked questions
Is Dahua IPC-PFW81642-A180 better than Dahua IPC-HDBW5441F-AS-E2?
Dahua IPC-PFW81642-A180 captures more pixel detail (4.1 MP vs 3.7 MP), useful for license-plate or face identification at distance. 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 IPC-PFW81642-A180 vs Dahua IPC-HDBW5441F-AS-E2?
Dahua IPC-PFW81642-A180 has a 180° horizontal FOV at 2.8mm. Dahua IPC-HDBW5441F-AS-E2 has a 95° horizontal FOV at 2.8mm. 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 IPC-HDBW5441F-AS-E2 reaches 30 m of IR illumination versus 30 m for Dahua IPC-PFW81642-A180. 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.
