The Problem with Traditional Attendance
Schools across the world face a silent productivity drain every single day — manual attendance. Teachers waste 5-10 minutes per class, proxy attendance goes undetected, and administrators have zero real-time visibility into who is actually on campus.
ProjectWorlds Multi School ERP V2.0 solves this with an industry-first AI-Powered IP Camera Attendance System — a contactless, fully automated solution that uses your existing CCTV infrastructure to recognize faces, mark attendance, and detect intruders.
How It Works
- Camera Streams — IP camera pushes RTMP video to the server (Hikvision, Dahua, or any generic IP camera)
- AI Processing — Python worker detects faces using dlib + face_recognition, computing 128-dimensional face vectors
- Identity Match — Each face is compared against known vectors using Euclidean distance
- Liveness Check — MiniFASNet anti-spoofing neural network verifies the face is real — not a photo or screen
- Evidence Capture — JPEG snapshot with bounding box saved as proof
- Attendance Mark — Laravel auto-marks attendance with 45-second cooldown per person
The entire pipeline runs in under 400 milliseconds per face — faster than a student can blink.
🛡️ Anti-Spoofing — Military-Grade Security
The dedicated MiniFASNet neural network defeats spoofing attacks:
| Attack Type | Detection Rate | Action |
|---|---|---|
| Phone screen with photo | 98.2% blocked | Logged as SPOOF |
| Printed photograph | 97.5% blocked | Logged as SPOOF |
| Tablet/laptop display | 96.8% blocked | Logged as SPOOF |
| Real live person | 99.1% accepted | Attendance marked |
🔄 Dual-Duty Mode — Attendance + Surveillance
A single camera serves two purposes simultaneously — Attendance Mode recognizes known faces and marks check-in/out, while Monitoring Mode logs every face including unknown persons for security auditing.
💰 Cost Comparison: 5-Gate School
| Solution | Hardware Cost | Recurring | Year 1 Total |
|---|---|---|---|
| Fingerprint (ZKTeco/eSSL) | ₹60,000 | ₹15,000/yr | ₹75,000 |
| RFID System | ₹40,000 | ₹50,000/yr | ₹90,000 |
| IP Camera AI | ₹15,000 | ₹0 | ₹15,000 |
IP Camera AI costs 80% less than fingerprint and 83% less than RFID for the same coverage. Already have CCTV? The additional hardware cost is ₹0.
