The reviews show that the Video Transmission delay is about 4-5 frames.which makes it not ideal for AC1/ Focus pulling. But the advertised transmission delay is less than 1ms, but it seems not! Can any users confirm this?
Asked by: Uday Bhaskar
The system is less than 1ms latency. Current monitor is 60Hz, causing latency itself. It could be proved by a test: connecting the monitor and camera directly and check the lag.

question

I know most hollyland products are very strong with functions, Do Hollyland products support DFS?
Asked by: Zohreh
Nope. Hollyland wireless use fixed channel. Don't support DFS. The upside is that it's more stable if you choose the right channel. That's why a lot of people using Hollyland product, think Hollyland is more stable than other brands like Teradek.The downside is that you need to change to the right channel yourself manually if the current is not good enough.
