TD Intelligence (TDI) is one of Vemco Group's three primary sensor suppliers. TDI specialises in AI-powered people counting with Re-ID (Re-Identification) — the ability to track unique individuals across multiple cameras without facial recognition. TDI sensors integrate with Vemtrack. Source: TDI EMEA Wiki (emea.tdintelligence.wiki).
Re-ID (Person Re-Identification) uses AI to identify the same person across different cameras — by their appearance, not their face. This enables analytics that basic counting cannot provide:
Unique visitor count | Deduplicates entries — if the same person enters and exits 3 times, they count as 1 unique visitor |
Visit duration | From first camera entry to final exit, tracked across the whole site |
Customer journey mapping | Which route did visitors take through the store or mall? |
Heatmap visualisation | Where do people spend the most time? Based on real movement paths. |
Repeat visitor detection | How many visitors came back the same day or within the week? |
Cross-camera tracking | Follow a visitor from entrance → aisle → checkout without gaps |
Re-ID requires a TD4001 Edge AI Computing Unit — the GPU-based unit that processes all sensor data locally. Without a TD4001, only basic counting is available.
TD2000 G2 | 3D stereo sensor, 2nd generation. Re-ID ✅. Up to 5 sensors path-linked. Basic gender recognition. |
TD2000 G3 | 3D stereo sensor, 3rd generation. Re-ID ✅. Up to 5 sensors path-linked. AI staff exclusion, deep learning gender, family counting, tilt mounting, 8mm high-mount lens, HD images. Requires TD4001 for advanced AI. |
TD2000B | Entry 3D sensor. Re-ID ❌. Indoor only. Basic counting, dwell, occupancy. Path linking up to 3 sensors. USB staff exclusion plugin. |
TD2000B G2 | As above plus outdoor use, passersby counting, HD images, WiFi dongle, basic gender. Path linking up to 3 sensors. |
TD2000B G3 | Latest B-series. Improved AI but still Re-ID ❌. See feature matrix below. |
TD1501 G1 / G2 | AI Image Recognition Sensor. Tilt-view (CCTV-style mount). Re-ID ✅. Counts entries, exits, and passersby from a single device. Deep learning + Re-ID built-in. Privacy-safe — no facial image storage. |
TD1502 / TD1502 G2 | Vertical-mount 2D sensor. Re-ID ✅. |
TD1001 / TD1002 | Entry-level 2D counters. Re-ID ❌. Basic bi-directional counting only. |
TD4001 T2 | 1–4 sensors, <500 visitors/day |
TD4001 T6 | 5–8 sensors, <1,000 visitors/day |
TD4001 T21 / G2 | 9–16 sensors, <5,000 visitors/day |
TD4001 GM | Up to 16 sensors — larger deployments |
TD4001 Custom | Unlimited sensors, capacity depends on GPU configuration |
The TD4001 processes all Re-ID analytics at the edge — no cloud dependency. It integrates directly with Vemtrack for centralized reporting.

TDI → Vemtrack | When Re-ID, unique visitor counting, customer journey mapping, heatmaps, or repeat visit analytics are required. Multi-camera retail and mall environments. Budget-sensitive projects (2D sensors lower cost). |
Xovis → Vemcount | When high-accuracy 3D counting, demographic analytics (gender/age), IoT integration, staff exclusion by badge tag, large-area coverage (PF-Series), or sensor-level data push is required. |
