Abstract: Multiple cameras within a vehicle, such as placed at multiple locations inside and/or outside a bus or semi-truck and trailer, may be chained together to provide a consolidated video stream that may be recorded and/or transmitted wirelessly to a cloud storage device. Rather that each of the cameras independently recording and/or streaming video content, each camera may be configured to deserialize an input video to identify video streams from separate cameras (e.g., such as based on associate virtual channel identifiers) and reserialize its own video stream with the other video streams in the received input. The serialized video stream is then transmitted to a next camera in the daisy chain and/or a video storage device.

Abstract: A video gateway device at a worksite (or other location) is coupled to multiple cameras on a network, such as multiple cameras at a business site. The gateway device determines video stream capabilities of each camera and, based on the capabilities, determines whether any additional video steams need to be created for particular cameras. For example, for cameras that provide only a high-resolution video stream, the gateway will generate (e.g., via downsampling) a standard-resolution video stream for artificial intelligence (“AI”) analysis and a low-resolution video stream for viewing by a user. However, for cameras that provide both a high and standard-resolution video stream, the gateway device uses the camera-provided standard-resolution video stream for AI analysis, rather than generating a new video stream on the gateway device.
