View switcher preview through the network

Is there any way I can view the ATEM 1 Production Switcher preview through the network instead of having a hardwire HDMI connected to the preview output?

Only with additional hardware.

What do you mean with "network" ? A real computer network or using the network cable ?

You are able to control the switcher through the network using the provided software. I was wondering if there is another piece of software that is able to connect to the switchers IP and see the previews.

No, you need aditional hardware to encode mixer out signal to same network an then connect to that encoded signal to preview it (for example use hardware rtp encoder whos encoding mixer out then connect with lets say vlc on that signal for preview)
