How onboard video and vehicle data are correlated
Video gateways, data gateways and onboard computers divide capture, vehicle-data access and local analytics responsibilities to form a dependable integration chain.
Video and vehicle data use different paths
Cameras produce continuous imagery while vehicle systems provide structured time, speed, location and operating data. Their formats and update rates require deliberate correlation.
The video gateway standardizes video
The gateway aggregates camera feeds, performs encoding and retention, then produces structured streams so the computer does not need to handle every camera's raw interface.
The data gateway provides operating context
A data gateway aggregates vehicle data and supplies a common time reference so video events can be associated with speed, location and operating status.
The computer performs local correlation
The onboard computer receives standardized video and vehicle data for local event analysis and alert records. Configured local capture and analytics can continue through communications outages.
Frequently Asked Questions
Why does the computer not connect to every camera directly?
A gateway centralizes video access, encoding, buffering, health monitoring and interface differences, allowing the computer to focus on correlation and analysis.
Why is common timing important?
It makes video events reliably traceable to vehicle speed, location and operating context.
