The problem you are solving

50,000 students. Hundreds of classrooms. Attendance marked on paper by a faculty member who has 90 seconds to call roll before lecture starts. It is inaccurate, gameable, and meaningless as data. We are replacing it with existing CCTV infrastructure — no new hardware, no wristbands, no apps. Just cameras that already exist, a model that recognises faces at scale in real-time, and a system smart enough to also tell you which rooms are overcrowded, which are empty, which have lights burning with nobody inside, and which need security attention. Campus intelligence, from cameras that are already there.

What you will build

Face recog.

Identify 50,000 enrolled students from CCTV feed — low-res, partial occlusion, varying angles

Attendance

Real-time auto-marking at scale, synced to the student ERP — no manual input

Crowd detects

Flag overcrowded rooms vs capacity threshold, real-time alerts to admin

Empty rooms

Detect booked-but-empty rooms and free them up automatically

Utilities

Lights on in empty room, fan running, AC on — flag for facilities team with camera snapshot

Edge + cloud

Low-latency processing at edge where needed, aggregation and analytics on cloud

Must have built something hard — any of these

Face recognition at 10,000+ identities

Real-time video analytics pipeline

YOLO / object detection production deploys

Multi-camera synchronization system

Edge inference (Jetson / Open VINO / ONNX)

Crowd / occupancy detection system

Competition — 3 rounds

Round 1

Given a set of low-res CCTV stills from a real campus: identify occupied vs empty rooms, count heads, detect lights-on-no-occupancy. Submit working code.

Round 2

48-hour sprint: extend your solution to handle a 10-camera simulated feed simultaneously. Latency under 2 seconds per frame is the bar.

Round 3

Live oral defense with Sachin and Hemant. Scale it to 500 cameras. Where does it break? How do you fix it?
