📐Interactive Floorplan Wi-Fi & CCTV FoV Canvas
Upload local floorplan (JPG/PNG), drag AP & CCTV markers, and export installation blueprints.
Technical Accuracy Note: Calculation results are engineering estimates based on standard RFC/IEEE/ITU-T models. Actual field performance may vary due to protocol overhead, hardware specifications, and environmental factors.
How to Use This Tool
- Enter building floorplan dimensions (width and length in meters), select wall barrier material attenuation, and set primary CCTV camera lens focal lengths.
- Upload a local floorplan blueprint image (JPG/PNG) or utilize the default interactive grid canvas to drag and position APs and CCTV cameras.
- Review estimated Wi-Fi coverage percentages, effective 5 GHz cell radii, channel allocation tables, and export the annotated visual floorplan as a high-resolution PNG.
Worked Example: Office Floor 20m × 30m (Brick Walls, 3 APs & 4 CCTV)
Computed example: A 20m × 30m office building (600 m² floor area) with interior brick walls (10 dB attenuation) requires a minimum recommendation of 3 AP units to ensure continuous 5 GHz coverage (-67 dBm radius 11.5m), paired with 2.8mm CCTV cameras (103° FoV).

Core Concept & Engineering Notes
How It Was Calculated (Formulas & Steps)
Mathematical Formulas
- Total Floor Area = Width (m) × Length (m)
- Effective 5 GHz Cell Radius = max(5, round(18 - Wall Attenuation × 0.65)) meters at -67 dBm
- Estimated Wi-Fi Coverage (%) = min(100, round((Installed APs ÷ Recommended APs) × 100))
- CCTV Horizontal FoV: 2.8mm (103°), 4mm (84°), 6mm (52°), 8mm (38°)
Frequently Asked Questions (FAQ)
Why is the -67 dBm threshold used as the standard Wi-Fi cell boundary?
A received signal strength of -67 dBm is the universal minimum threshold recommended by enterprise vendors (such as Cisco, Aruba, and UniFi) to support jitter-free voice/video streaming and trigger smooth client roaming before dropped packets occur.
How do you avoid co-channel interference on the 2.4 GHz band?
On the 2.4 GHz spectrum, strictly assign non-overlapping channels: Channels 1, 6, and 11 using 20 MHz channel widths. Ensure adjacent access points never share identical channel frequencies to prevent contention overhead.
What is the functional difference between 2.8 mm, 4 mm, and 6 mm CCTV lenses?
A 2.8 mm lens offers wide horizontal viewing (103°) for open rooms with near identification (4 m). A 4 mm lens (84°) balances coverage width with depth (6 m). A 6 mm lens (52°) narrows the cone for long corridors and distant identification (9.5 m).
Is the uploaded floorplan image file stored on InfraCalc servers?
No. All blueprint image rendering and interactive canvas calculations execute 100% locally in your client web browser via HTML5 FileReader and Canvas APIs. Zero image data or location coordinates leave your machine.
