When my pan cam v4 records it does fine, but about a third of the time it fails to see little things. Like a 20 foot fed-ex truck driving straight through the way point. there doesn’t seem to be any pattern, sometimes a vehicle comes but never leaves and other times it leaves but never comes. I’ve changed the sd card to no effect and my wifi is strong and consistant. Is anybody else dealing with this kind of problem?
Are you using “smart detections” or “smart motion tracking”? If so, it will only record/notify if it recognizes the object.
Another thing to keep in mind is you can only log one event ever 5 minutes, maybe you’re seeing the effects of that? It will still record to the SD card, just won’t “tag” or “notify”. But you’ll be able to see the little green spot on the timeline if you’re in event only recording mode.
Since my first post I have replaced my camera. The first one stopped panning. Wyze replaced it under warranty with no big hassle (a real plus), however I still have the same issue. It has to be in the software. Saturday it hadn’t recorded anything for two hours before a Fed-Ex box truck arrived. The truck drove straight thru the way point and the camera recorded nothing. Then it recorded when the truck turned around and left. The recording is set to all events.
Do you have it set up for “smart detections” or just all motion? With smart detection, it needs relatively good connectivity to be able to upload to wyze’s server for analysis, and it needs a fairly “straight on” view of the object to be able to recognize it.
You can also try tweaking the sensitivity settings. My Panv3s are set to “all motion” and 50 sensitivity. I use track motion but not pan/scan. My front one tracks every car that goes by, and it is mounted about 25 feet off the ground, looking at a street that is around 20 feet away from it.
I’ve never tested smart detections though as I don’t have a subscription.
Missing Events seems to be a thing with Wyze’s connection to your camera(s) as I found out over the years.
Missing Events and Random SD card corruptions that required a reformat of SD card became to much of a hassle “babysitting” the cameras that I finally gave up and moved on to other better brands that don’t require a subscription or a constant Internet connection. Being on a cellular data connection which sometimes loses connection for 20-30 seconds occasionally I find non-cloud cams a better option.
I use Reolink 4k cams for the “Security” camera needs and have a NVR save all video from cameras besides the SD cards in camera.
No issues whatsoever unlike my Wyze cams had
Also trying Tapo’s and so far they’re a good cost comparative replacement for Wyze that is also subscription free self hosted camera system.
You have Better control of your videos rather than being on a cloud server that could “accidentally 
” give your videos to another user if the server has a hiccup 
see the other post on this, looks like a third time Wyze has F’ed up
