Caddx pushes out a new combination of FPV cam and DVR with 4K30 and H.256 encoding! Reason enough for me to pre-order the Tarsier right away so we can put it to the test at the end of the month!
The stats look promising!
Dual lens with dedicated 4K DVR supporting a descent H.256 encoding, hardware anti shake system, supposed to be fast (<10ms they say! But lets see about that), controlable via FC and taking 18g in total … The Tarsier sounds like a winner to me.
