Hi , I'm not a VA person, I'm a sound guy. I work with a Marshall dual monitor with an HDMI input, operating for film. I m looking for a non extra expensive as teradek option to have a picture wireless. VA here is telling me that Niryus pro is a good compromise (450$) to have a wireless picture. Thing is on amazon custumers say that the signal hardly break walls. I'm wondering if you guys know any alternativesand any suggestion for a good product. I just need a reference image to know what is going on the shot, not a extra sharp picture. Hope you will understand, hope you have some clues. Regards Arnaud Ps: english is not my first language.
