Everything RoadEye does

All of it on the device in your car. Nothing here needs an account, a phone app or a signal.

Reads the signs you pass

Stop, speed limit, school zone, curves, merges and more, spotted and confirmed before they are shown.

The detection model runs on the AI camera's own sensor, 15 times a second. A sign is reported once it is seen in three of the last five frames, so a flicker of a billboard never makes the screen. Speed limit signs are read for their number, and the posted limit stays on the screen until the next one.

Knows the limit, from the sign and the map

The posted limit from the last sign, the map's limit for the road you are on, and whether they agree.

With a GPS, RoadEye looks up the road you are on in its offline map and shows its speed limit, the next limit ahead and how far it is. When the map and the last sign disagree, it says so, and the sign wins.

A dashboard, not a debug window

Your speed on a dial, the limit beside it, the signs of the last two minutes, a mini-map of the next turn.

Several looks to choose from, for day and for night, drawn over the camera's view or on a plain ground. The screen is a touchscreen: tap the buttons, swipe to the diagnostics, nothing needs a keyboard.

A dash camera, when you want one

Loop recording at 720p, 1080p or 1520p, stamped with time and speed. Off until you turn it on.

Set its share of the disk from 4 to 64 GB, keep a clip on a sudden stop, or save one from your phone with a tap. Detection comes first: recording pauses rather than slowing the signs down.

A heads-up for marked police vehicles

“Police ahead · 35 m, right” once per vehicle, for the ones near enough to show their markings.

A small classifier looks at the vehicles the camera already follows. It is a heads-up, never an all-clear: it cannot know an unmarked car.

A page for your phone

What the device is doing now, where it is navigating to, the dash camera's settings, the clips, the sign photos.

Scan the QR code on the device's Help page and the phone page opens on the same Wi-Fi or hotspot. Nothing goes through a cloud.

Updates itself, and never while you drive

A new release downloads in the background and starts next time. If it will not start, the last one comes back.

One install line sets everything up. After that there is nothing to maintain: the device checks for releases when it is online and switches to the next one at the next start.

Your drives stay in your car

Sign photos, clips and logs are kept on the device's own storage. Nothing is uploaded.

The device only goes online to check for a release and to fetch map tiles, for which only the tile's position is sent. There is no account, no app store and no subscription.
