Vehicle Detection & Tracking
Count and track every vehicle that passes, separated by class.


Measure billboard audiences for real


A CCTV or traffic camera facing the billboard streams its video to the Netra Node installed at that point.

The node recognises every passing vehicle and separates it by class: motorcycle, car, truck, bus. Identities are blurred before anything leaves the device.

Only counts and their timestamps are sent to Karsa. Raw footage never travels, and the node keeps counting when the network drops.

Processing is split in two: recognition runs on the device at the site, aggregation and reporting in the cloud.
Creative changes with the weather at the site at that moment.
The ad format adapts to the volume of traffic currently passing.
The board shows event markers — the ten-thousandth vehicle of the day, for instance.
Not just a pass-by count: how long vehicles actually stop facing the screen.
QR codes whose destination shifts with the campaign context.
Emission figures for campaigns that require environmental reporting.
Count and track every vehicle that passes, separated by class.

Motorcycles, cars, buses, trucks — each counted on its own.

A different message for each site.
Site rent and advertising tax are paid in full without knowing how many vehicles actually passed during the booked hours.
One site is compared against another using estimates, not a count you can show an advertiser.
Reports to advertisers are built from third-party numbers neither side can verify.
Play times are decided from habit, not from density measured at that specific point.
Camera count, viewing angle, and network conditions differ at every site, and all three shape how it is installed. We look at the location first, then put a quote together.
Netra Billboard is put together around the conditions at its site, so the price comes out of a quote rather than a list. Tell us about the location and we will look first.
