How to organize motion video recording from multiple IP cameras on raspberry pi4 using hardware acceleration?

Question

Video capture

There are three IP cameras that transmit a compressed h.264 video stream over rstp with a bit rate of 5 Mbps. The task is to record motion detection video using raspberry pi4.
What tools to use to record video so that transcoding is performed not by software, but using a hardware decoder so as not to load the processor.
Well, can rpi handle this task at all?

Answer 1

Set up a built-in motion detector and ftp recording in camcorders, set up an ftp server on rpi.
