H5S starts from r18.2, and USC starts from 1.4, directly supporting the UVC VM6300 platform. It has built-in VM6300 platform IMOS protocol, supports real-time video, pan-tilt control, and playback.

USC has built-in iSCSI protocol, which can directly read and write iSCSI lun block devices, and supports iSCSI target auto-discovery, greatly reducing configuration time. Video data is written in streaming mode. The working node can be configured as a hot standby mode, which can achieve smooth switching of the device management node to the hot standby node, thus achieving redundant backup of device management video. Switching servers without needing to back up video reduces system downtime to a very small range. 

The main functions of H5S r18 are as follows:

Chrome supports RTC H265 decoding starting from version 127. This eliminates the need for servers to transcode H265. USC and H5S will automatically detect the decoding types supported by the browser and determine whether to start transcoding. This way, clients don't need to worry about whether a camera supports H264 or H265. It is recommended to use client devices with GPUs as much as possible. This eliminates the need for servers to perform an H265-to-H264 conversion process, significantly saving server CPU resources.

In order to better serve customers around the world, we have released a new version of our global website, and H5S and USC will continue to update the global site in sync
