Queue control, without the guesswork

Make the next lane choice. Fast.

Live status • On-device vision • Optional remote screen

Lineus helps you direct the next customer to the best checkout lane, based on what’s happening right now: queue size, lane activity, and current service flow — presented as one simple “Next lane” recommendation.

PRICE: FREE

SETUP: CAMERAS + LANES

OUTPUT: NEXT LANE

BEST PERFORMANCE: NVIDIA GPU + CUDA

Lineus is FREE. No subscriptions, no feature locks. For the smoothest real-time experience, you need a CUDA-capable NVIDIA GPU (CPU works, but it will be slower and less responsive under load). Everything runs locally on your machine; the optional “Remote Screen” is served from your PC to your local network.

How it works (user view)

Enable the lanes you want Lineus to watch (Lane 01…20, or fewer if you prefer).
Connect each lane to a camera source (one camera per lane).
Start monitoring. Each lane card updates continuously.
Lineus recommends the next lane by comparing estimated waiting time across all active lanes.
If wait times rise, Lineus shows a clear message suggesting you open another lane.

What you don’t need to do: count people manually, guess which cashier is about to finish, or flip between feeds. You just follow the “Next lane” call when you need it.

What you see on screen

Lane status (e.g., free / attending / payment / offline).
Queue estimate (a simple number, updated in real time).
Activity indicator (whether the checkout is currently active).
Confidence so you can tell when a camera view is weak or obstructed.
Next lane highlight — the one Lineus believes will clear the next customer fastest.

Best practice: mount cameras with a stable view of the queue area and checkout zone. Better input gives more stable recommendations.

Daily workflow (simple manual)

Morning: enable today’s open lanes and check camera feeds.
During peak: watch the “Next lane” and the open-lane suggestion message.
When staffing changes: enable/disable lanes as they open/close.
If a lane is blocked: mark it as blocked (so it won’t be recommended).
Close: disable lanes and stop monitoring.

Remote Screen (for a tablet/phone)

Lineus can show a clean “Remote Screen” view on another device (tablet near the queue, supervisor phone, back office display). It’s designed to show the same essentials: the next lane, lane summaries, and any “open another lane” alert.

Tip: keep the remote device on the same local network as the PC running Lineus. No cloud account required.
