New in the SevinHub suite: RadarHub watches any video feed, detects every vehicle, measures its real speed in km/h, counts traffic by type, and flags speeders with photo evidence. It runs entirely on your own hardware, and you can try it in your browser right now.
Some projects are business decisions. This one is a childhood dream.
You have probably seen the viral story: a student spent 20 dollars on AI credits, built a video speed radar, and sold it for a life-changing amount. When I saw it, I realized two things. First, the technology behind it is real and well understood. Second, there was no reason I could not build my own version, properly, and make it a product anyone can own.
So I did. Meet RadarHub.
What RadarHub does
Point it at any road camera and it turns raw video into traffic intelligence:
- Detects every vehicle (cars, trucks, buses, motorcycles) with an AI vision model. No training needed.
- Tracks each one with a persistent ID across frames.
- Measures real speed in km/h. Not a pixel guess: a calibrated perspective transform maps the camera image onto the road plane in meters, the same principle professional systems use.
- Counts traffic by type as vehicles cross a virtual line.
- Flags speeders above your limit, saves a photo snapshot of each one, and exports everything to CSV.
- Shows it all live on a web dashboard you open in any browser.
Try it in your browser, right now
I built a live demo that runs the AI entirely on your device: your camera feed never leaves your phone or laptop. Point it at a street and watch it detect, track and count.

It works with the cameras you already have
RadarHub accepts three input types: a video file, a live RTSP/IP camera stream (which covers virtually every CCTV camera made in the last decade), or a webcam, including OBS Virtual Camera. Calibration is point-and-click: you mark 4 points on the road, tell it the real size in meters, and from then on speeds are measured on the ground plane.
Your footage stays yours
This was non-negotiable for me. RadarHub runs 100% on your own hardware. There is no cloud processing, no per-camera monthly fee, and no footage ever leaves your machine. For anything traffic-related, that privacy model matters.
Who it is for
- Municipalities and campuses that want data on speeding streets before investing in enforcement.
- Parking, logistics and industrial sites enforcing internal speed limits with photo evidence.
- Traffic engineering consultancies running studies from any footage. The Extended license lets you white-label it.
One honest note: official speeding fines usually require type-approved devices. RadarHub is a measurement and analytics tool, built for studies, private sites, monitoring and evidence gathering.
Pricing
Like everything on SevinHub: one payment, yours forever. 99 EUR for the Standard license with full Python source code, or 299 EUR Extended with white-label and client-project rights. Updates included.
