 This is the AXUN Cineview Nano. It's a live HDMI wireless transmitter device as you can see I've connected three different devices my iPad my iPhone my Android Google Pixel and it's all connected wirelessly to this adapter Which I've connected to my Sony a7c So if you want to see what you're filming at a distance then you can wirelessly connect it via the AXUN C app to this adapter Which I think is absolutely great. It has very minimal latency up to 60 milliseconds It can shoot up to 500 feet and it emits 5g Wi-Fi as well and you can connect up to four devices Just check out the latency on these devices How cool is that? I can now use multiple devices or I can just use my phone at a further distance to see Myself when I'm recording rather than having to go to the camera every time and coming back to do the filming Very convenient factor.
