Verdict
Dahua IPC-MFW7442K1-Z7-T40 reaches further (120 m vs 30 m) — better for perimeter and parking-lot wide shots. Dahua IPC-MFW7442K1-Z7-T40 has stronger IR illumination (120 m vs 30 m) — better for unlit corridors and night perimeter.
Frequently asked questions
Is Dahua IPC-MFW7442K1-Z7-T40 better than Dahua IPC-PFW81642-A180-S2?
Dahua IPC-MFW7442K1-Z7-T40 reaches further (120 m vs 30 m) — better for perimeter and parking-lot wide shots. Dahua IPC-MFW7442K1-Z7-T40 has stronger IR illumination (120 m vs 30 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 IPC-MFW7442K1-Z7-T40 vs Dahua IPC-PFW81642-A180-S2?
Dahua IPC-MFW7442K1-Z7-T40 has a 40° horizontal FOV at 8-56mm. Dahua IPC-PFW81642-A180-S2 has a 180° 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-MFW7442K1-Z7-T40 reaches 120 m of IR illumination versus 30 m for Dahua IPC-PFW81642-A180-S2. 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.
