Zowietek ZowieBox HDMI Reviews

Wonderful product

This is my second one. Great product that does a lot

I requested a replacement for my faulty Zowiebox device, and the faulty device was sent again.

The replacement device was the same one I sent back as defective. When I opened the box of the device, I found the message I had put in the box about the defect. The device number was also the same as the one I sent back. Of course, the defect remained.

See any errors on this page?

Can this receive and decode an NDI stream from WiF

Can this receive and decode an NDI stream from WiFi? Will it reconnect whenever that NDI stream is available again?
Asked by: Jonathan
I have not tried NDI over Wi-Fi but it does reconnect over ethernet. If I drop the encoder and reenable it will disconnect and reconnect on the decoder to last connected NDI Stream.
