Remote source PTZ Canon CR-N300 + ATEM HD8 ISO

Pls help to add remotely source PTZ camera Canon CR-N300 to ATEM Television studio HD8 ISO. I know that I can add Blackmagic cameras, but cannot easily add another.
As option we can use for each camera sdi over ip transmitter/receiver kit? May some another ways?
