Detailed edge structure

Determine: Structure for ingesting IP video cameras feed in Amazon Kinesis Video Stream

The sting structure has three modules: controller, video recorder, and video uploader (see the earlier diagram). Whereas the default setting of the Kinesis Video Streams connector part is to stream the video, it has an optionally available performance of recording video on the file system for native storage. The controller acts as a dealer between the recorder and the uploader. It additionally facilitates communication between the 2. The controller first initiates a pair of piped enter and output stream objects. The video recorder retrieves stream knowledge from the digicam and places the info into the piped output stream. Lastly, the video uploader takes stream knowledge from the piped enter stream, then uploads the info to Kinesis Video Streams.

Scaling the answer

Subsequent, we’ll have a look at sizing and limits to see how the answer scales. Within the structure, the sting connector for Kinesis Video Streams part and Greengrass Core shouldn’t have any scaling limitations. As the answer makes use of AWS IoT SiteWise to handle the RTSP digicam configuration, the one onerous restrict is from the AWS IoT SiteWise youngster belongings quota, which is fewer than 2000 youngster belongings per father or mother asset. The variety of cameras that may be supported by the sting system/Hub solely relies on its {hardware} configurations. If there’s sufficient community bandwidth and {hardware} capability, the AWS IoT Greengrass system can assist extra cameras. From our inside testing, we examined 10+ cameras related to the identical edge system to ingest the feeds with none points. Confer with the documentation Kinesis Video Streams API limits and quotas.

Under are some pattern edge system configurations and the variety of video streams they’ll assist for optimum efficiency:

1. A small occasion (like Raspberry Pi 4 Mannequin B) with 2GB RAM and 16GB SSD can assist as much as 2 1080p HD RTSP cameras importing to the cloud on the identical time with a community velocity of 100 MBPS.
2. A medium occasion (like NVIDIA Jetson Nano Developer Package) with 4GB RAM and 16GB SSD can assist as much as 4 1080p HD RTSP cameras importing to the cloud on the identical time over a community velocity of 100 MBPS.
3. A big occasion (like Intel NUC) with 25GB RAM and 1T SSD can assist as much as 24 1080p HD RTSP cameras importing to the cloud on the identical time with a community velocity of 600 MBPS.
