Hi Jack hope you're looking after yourself and keeping well. I've been playing around with my ACE2 to get a better feel for it and found to connect I have to start the engine until ACE2 says recording started then stop it, I then wait until it says recording stopped, parking mode then open the App and select connect to wifi which takes me to wifi settings, I select the ACE wifi name and it connects then I back out to the App. I don't know what would happen in the event of an accident that prevented me starting the car which would prevent me downloading any recordings, I guess I'd have to slide the camera off the base and take it with me until I can access the files. I don't get with the camera on why I have to start the engine to get the camera into record mode then stop it in order to stop record mode before I can connect. I can't connect without starting the engine first.
Once connected when I try to view recordings some play fine, others take an age to play, some only show recordings from the front camera, it seems very hit and miss. I'm not sure if the MicroSD card quality has any effect on the speed and reliability of displaying recordings, the card that's in mine doesn't have a brand name or MLC stamped on it. Yesterday I had to take some medication to my daughter and on the way a pickup pulling a large trailer passed in the opposite direction, as it approached the trailer slewed out toward me and just missed fortunately. When I got home I went to check the footage on my ACE2 and found it and decided to download it but halfway through downloading the camera powered down so I went through the hassle of reconnecting to find the part of the recording up to the camera powering down has gone missing from the camera. I'm lost as to why the camera powered down part way through a download and why it seems so precarious trying to view recordings directy from the camera. The only time I've needed a recording and ACE2 let me down which raises a few questions concirning reliability which is paramount in a dashcam.
