Data Logging
Designed to capture, store, and stream vehicle data in real time. It adapts to the most demanding use cases, from test benches to on-road validation, and gives you full control over data acquisition.
Zero Data Loss
“Our data upload is stable and 100% reliable, with no data loss. The system is designed to prevent recording gaps and eliminate the need to re-run tests.
Multiple Sources
The system supports a large number of input and sensor connections. This extends test coverage, simplifies logistics, and reduces installation back-and-forth.
Direct Vehicle Network Connections
Our onboard HMI, accessible via Ethernet or Wi-Fi, lets you import DBC files to view vehicle network data in real time.
Onboard Video Processing
Our device processes video directly within the system. This opens the door to integrating multiple features that eliminate the need for post-processing, such as automatic blurring of license plates and faces.
Vehicle Diagnostic Routines
Our product lets you automate diagnostic requests to get a complete picture of your vehicle’s status. Identify the root cause of a fault faster and make the right decisions, with no loss of information.
Real-Time Fleet Tracking
Short, actionable information (alerts, errors) is reported live, in real time. All relevant data is available on a remote platform, which also lets you view and manage your devices’ configuration. You can react immediately when an issue arises, while processing the bulk of the data later.
Remote Management
Our teams can monitor the status of your devices and deploy firmware updates on demand, on a per-device basis. This eliminates time-consuming on-site visits and ensures greater responsiveness.
Automated Data Transfer
As soon as a recording file is complete, it is automatically sent to the server via Wi-Fi or cellular network.
Contextual Video Capture
A simple press of a button marks the event and activates all 8 cameras. The relevant moment is instantly tagged, and our smart video acquisition captures the context up to 60 seconds before and after the event. This reduces sorting time and helps identify the root causes of anomalies.
Smart Storage
The system is configured to transfer data to the server. Storage is automatically updated, deleting what has already been transferred. Our device can therefore handle long test campaigns without running out of space.
Custom Applications
Our technology lets you add your own applications and trigger custom actions. The system adapts to each team’s methods, without changing the way they work.
Quick Installation
Setup is designed to be simple: the case containing our device can be placed directly in the trunk. This reduces handling, minimizes errors, and gets your tests started faster.
“Cybersecurity
As a TISAX-certified company, we provide our partners with the added assurance of a recognized security standard for the protection of our data and infrastructure.
