What is an onboard video gateway and how should it be selected?

Define the gateway role first

A video gateway is neither a single camera nor merely a storage appliance. It sits between cameras and the onboard computer, display or ground system, organizing access, encoding, event handling and retention.

Confirm interfaces and channel count

Start with camera count, mounting areas, IP or analog signal types, and allow capacity for future channels, snapshots, display output and service access.

Review storage and standardized output together

Retention period, event priority, power-loss protection and health monitoring affect traceability. Confirm codec, resolution, frame rate, bandwidth and timing requirements for downstream integration.

Check the installation environment

Equipment-bay space, power, cooling, grounding, vibration, cable routing and maintenance access all need confirmation before installation.

How is a video gateway different from an onboard computer?

The gateway manages camera access, encoding and retention; the computer correlates standardized video with vehicle operating data for local analytics.

Can existing cameras be connected?

This depends on their interfaces, power method, codec, resolution and cable conditions. These details should be checked before integration.
