Video Latency Test: Phantom 3 Pro, Phantom 4 Pro, Inspire 2

It wasn’t that long ago that word on the street suggested that some drones have zero latency video transmission. Even some drone companies at CES 2017 suggested that their drone had zero latency. While it is a nice thought, the reality is that every signal needs time to be transferred regardless if it’s at 2.4 GHZ or 5.8 GHZ. The only real zero latency one can have is with a mirror. Even so, light can take time to travel to the mirror surface and reflect back. However, light speed is so fast, you would never notice any time lapse.
