How to Use This Tool

  1. Enter building floorplan dimensions (width and length in meters), select wall barrier material attenuation, and set primary CCTV camera lens focal lengths.
  2. Upload a local floorplan blueprint image (JPG/PNG) or utilize the default interactive grid canvas to drag and position APs and CCTV cameras.
  3. 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

Designing physical placement for wireless Access Points (APs) and surveillance cameras directly on architectural 2D floorplans represents a cornerstone of modern IT site engineering. Simulating coverage radii and camera viewing cones over digital blueprints allows infrastructure engineers to identify optimal mounting locations, eliminate physical blind spots, and eliminate co-channel interference long before structural cabling and conduit runs are installed on site. In radio frequency (RF) propagation, construction materials introduce substantial signal attenuation. Interior drywall and gypsum partitions attenuate Wi-Fi signals by approximately 3 to 5 dB, standard brick masonry introduces 8 to 12 dB of path loss, and dense reinforced concrete walls can attenuate RF power by 15 to 20 dB or more. Because 5 GHz carrier waves experience higher absorption rates than 2.4 GHz frequencies, material attenuation dictates cell sizing. This visualizer establishes an empirical -67 dBm cell boundary, representing the industry benchmark for high-throughput client connections, low-latency voice over Wi-Fi (VoIP), and seamless fast BSS transitions (802.11r/k/v). For video surveillance deployment, visualizing camera lens Field of View (FoV) cones ensures compliance with the international DORI standard (Detection, Observation, Recognition, Identification per EN 62676-4). A 2.8 mm wide-angle lens yields an expansive 103-degree horizontal viewing angle ideal for broad situational awareness, but achieves facial identification up to roughly 4.2 meters. Conversely, a 6 mm or 8 mm telephoto lens constrains horizontal coverage to 52–38 degrees while projecting facial identification capabilities out to 13 meters, making it the superior choice for perimeter gates, access control checkpoints, and elongated corridors.

How It Was Calculated (Formulas & Steps)

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?
