Works with only ONE? and barely.

Did not perform as listed. Wanted to run 3-5 of them. If you have two of them on at a time they start dropping frames. If you have 3, one of the three will loose connection over and over. Channel scanning, pairing, close line of sight made no difference. Tried 300 and 400s. Same problems. Also, if you using BM switcher and cameras, THEY ARE ONE DIRECTION! You can not get signal back from the cameras for control.

A must have wireless system for your live streaming or direct in church service

Stable frequency, good connectivity and low latency. I use it inside our church with the Atem mini extreme iso with sony a series for live streaming the quality was just perfect. No more cables from camera to the atem everything was wireless and cleaned

So far SO good!

Been using the HLD pro standard dual TX and Rx for almost 2 weeks. Very reliable signal. Negligible latency for our workflow. Clean consistent signals on both ends. The app can be a little clunky at times but the app is not why I invested with HLD.

Eventually it works

Took a long time to connect via wifi HLD. Eventually it started working randomly only to find out it wasn?t a great solution for live streaming.
