Choosing the right people counting system is a strategic decision for any business looking to optimise retail operations, improve marketing ROI, or support store planning decisions. One of the key considerations in selecting a solution is the coverage width per device-how wide of an entrance a single unit can effectively monitor at different mounting heights.
With a wide variety of vendors available—such as FootfallCam, Brickstream, V-Count, Xovis, Irisys, Axis, and Hikvision—facility managers and IT teams often find it difficult to compare technologies fairly. This blog aims to provide a clear, side-by-side coverage table comparison using published technical specifications, helping you understand how many devices you’ll actually need for your environment.
Whether you’re dealing with wide entrances or open-plan layouts, this guide will highlight the differences in performance and cost-efficiency between major brands.
1. Coverage Width by Mounting Height
The table below compares the maximum coverage width each people counter model can achieve at various ceiling heights. The wider the coverage, the fewer devices you need to install—saving on hardware, cabling, and installation costs.
| Mounting Height (m) | FootfallCam | Brickstream 3D Gen2 | V-Count Nano | Xovis PC Series | Irisys Vector 4D | Axis P8815-2 | Hikvision DS-2CD6825G0/C-IS | Milesight VS125 | ShopperTrak Orbit 8 |
| 2.1 | 4.36 m | 1.50 m | 1.50 m | – | 1.60 m | – | 1.02 m | 1.21 m | 1.60 m |
| 2.5 | 5.20 m | 2.20 m | 2.00 m | 2.63 m | 2.27 m | 1.99 m | 2.30 m | 1.94 m | 2.70 m |
| 3 | 6.23 m | 3.50 m | 2.80 m | 3.53 m | 2.99 m | 3.06 m | 3.58 m | 3.16 m | 3.60 m |
| 3.5 | 7.27 m | 4.70 m | 3.20 m | 4.69 m | 3.70 m | 3.53 m | 4.86 m | 4.37 m | 4.30 m |
| 4 | 8.31 m | 5.90 m | 3.60 m | 5.84 m | 4.41 m | 4.00 m | 6.14 m | 5.58 m | 5.00 m |

2. Sample Floor Plan Deployment
The number of people counting units required to cover an entrance significantly impacts project costs, installation complexity, and ongoing maintenance. FootfallCam 3D Pro2 (2025) stands out with the widest coverage per unit, allowing businesses to deploy fewer devices while maintaining high accuracy.
If you’re planning a rollout across dozens or even hundreds of sites, the difference in hardware cost and installation workload quickly adds up. Choose a solution that offers not just counting accuracy but also infrastructure efficiency.
