Can I use the wifi of the GoPro to stream the video?

To avoid having too many cables, using the wifi of the GoPros sounds a good idea.

But we're pretty comfortable with the fact that it will not work well, for the following reasons:

• Activating the wifi heats more the GoPros.
• Wifi with the GoPros is to have a preview image, not a full resolution image. The video is compressed when sending over the Wifi, vs uncompressed with the HDMI.
• Having 6 wifi networks in the same environment requires 6 wifi USB keys.
• Wifi is much less reliable than HDMI.
