I havent used mine yet
still deciding if im going to return it, but Caddx Tarsier is a delicate unit, there are complaints about it and doesnt last long
it only works with 32gig micro cards although the manual states 64gig, (ofcourse I bought the recommended highest quality 64gig) many guys complained not much recording room with only 32gig for a 4K cam, it may also only record in small clips you need to stitch together
I think you need a cell phone to make camera setting changes thru wifi, and its reported that your best not removing the sd card just using your cell phone and wifi to get your video recordings, the dvr is too delicate to keep removing the micro sd card the ribbon cable is extremely weak my has split in strands just looking at the unit and is reported a weak point in the unit....and they give you a spare, they know its an issue
do some reading on reviews first
