Bought Ghost 4K a month ago, used it as lid-cam for a few weeks, bought two more (one for car and one for rear of bike).
Have not seen any sign of red flare.
Drift website has latest firmware as 1507 but when I connected my cams to the Drift Life app earlier this evening, I was prompted to update to v1513. Done.
There is a 1080 120fps mode. 4K max fps is 25, but 4KUHD has 30fps, and 2.7K has 60fps.
A few weeks ago I reported Car DVR mode did not work on battery power. Drift support acknowledged my message and said that this was by design. Latest firmware now includes ability to run Car DVR on battery. You're welcome
I've also reported that there is no way to connect one remote control to multiple Ghost 4K cameras. Hopefully they'll address that one soon too.
Video quality is excellent. Audio is excellent; I use the external mic connection wired through to a mic inside lid.
Live streaming (from the bike over mobile data) worked the first time I tried it, and the live view on phone/tablet via Bluetooth was very handy when I was positioning and sticking the new lid connector (had to move it because my previous Ghost-S connector position caused the footage from the 4K to point too far left).
If anybody has a question I'll be happy to give it my best shot.
Cheers!
Matt
