Three channels of 2 million HD webcams, 1t storage, can be stored for a few days? Also, can I change the encoding format from h264 to h265?

2 million = 1080P, with 1080P HD video, 1 camera 1 hour is about 1G, 3 cameras 1 hour is 3G, 24 hours is about 72G,/kloc.

The encoding format h264 can be changed to h265, and H.265 takes up 50% less storage space than H.64. H.265 can transmit 1.5Mbps1080p.
