Full system vs. Low-Cost alternative Configuration.
| Component | Full system configuration | Low-Cost alternative | Cost reduction | Performance impact |
|---|---|---|---|---|
| Visual Sensing | 24× HD cameras (Hikvision, 8MP) - $180,000 | 6× lower-resolution cameras (4MP) + crowdsourced smartphone data via public WiFi analytics - $35,000 | 81% reduction | −15% accuracy in detailed crowd analysis |
| Computing Infrastructure | Dedicated cloud servers + edge GPU nodes - $120,000 | Edge computing (Raspberry Pi 4 clusters) + federated learning - $45,000 | 63% reduction | + 45ms latency, suitable for non-critical applications |
| Communication Network | Dedicated fiber optic + private LoRaWAN - $95,000 | Public WiFi infrastructure + shared cellular networks - $18,000 | 81% reduction | Reduced reliability (96% vs. 99.8% uptime) |
| Acoustic Monitoring | 16× professional-grade microphones - $32,000 | 4× consumer-grade USB microphones + smartphone crowd-sourced audio analytics - $2,400 | 93% reduction | −20% precision in activity detection |
| Software & Integration | Custom development + commercial ML licenses - $45,000 | Open-source alternatives (TensorFlow, OpenCV) + community development - $12,000 | 73% reduction | Requires more technical expertise for deployment |
| Total System Cost | $472,000 | $112,400 | 76% reduction | 15–20% overall performance decrease |
