The operator's problem
Advertisers pay for their ad to run. You can't prove it did.
A scheduling log says an ad was sent. It can't prove it played, in full, on a screen that was on and seen. That gap is where your revenue quietly leaks away.

Fleets managed by hope
Black screens run for days — you hear about it from the client.

Every one of these comes back to the same gap.
Here's how Vojo closes itThe fix
Three products. One platform. Every play proven.
Each does one job exceptionally well — and together they close the loop, from the screen on the street to the invoice on the advertiser's desk.
01Software + optional hardware
Smart DOOH Player
Screens that run themselves — and recover without a site visit.
A drop-in player built for the field. It keeps playing from local cache when the network drops, a watchdog heals it from freezes, and it restarts and resumes on its own after a reboot or power cut — all managed from your desk.
- Runs on Vojo hardware, or a cross-platform build for your own
- Plays video, image & HTML — cached locally to run fully offline
- Self-heals from freezes and restarts itself after a power cut
- Push content, reboot and diagnose any screen remotely
- Weighted ad mode — paid priority and loop budgeting
- Optional programmatic mode — fills inventory from partner ad-servers
Uptime you never have to babysit.

Vojo Harvester
Patented · UK & USHard proof of exactly what hit the glass — not what the schedule hoped.
The only patented Proof-of-Display: an independent sensor that watches the screen itself, fingerprints what genuinely displayed, and ties it back to the campaign — so every play becomes evidence you can put in front of an advertiser.
- Patented sensor technology — granted in the UK & US (EU pending)
- Independent verification — measures the screen, not the playlist
- Fingerprint-matches real display to each scheduled campaign
- Catches black screens, freezes, wrong content & downtime
Win the dispute. Charge the premium.

How it works
Three pieces. One verified loop.
Each Vojo product does one job well — together they close the loop from schedule to proven play to paid invoice.
- 01
Schedule in the CMS
Build campaigns and push content to any screen in your network from one portal. The Smart DOOH Player picks it up — online or off.
- 02
Play on the Smart Player
The player runs your schedule on the screen, resilient to outages, and reports its playback back to the platform in real time.
- 03
Prove with the Harvester
The Harvester independently verifies what actually displayed and matches it to the campaign — generating Proof-of-Display.
- 04
Report on evidence
Verified delivery flows into advertiser-grade reports — so you can charge a premium and win the disputes you used to absorb.
A continuous, verified loop
Pricing
The platform's free. Pay by the device.

FAQ
Questions screen owners ask
No. The Smart DOOH Player runs on the screens you already own — on Vojo hardware or a cross-platform build for yours — and the Harvester attaches to verify them. Vojo is the operating layer, not new glass.
