@railfan-arizona_485965826351268 I changed to Reolink camers because of the app and client software. The cameras, while a bit higher in price, are just as good as others. Each client upgrade has been a bit more buggy than the previous. Reolink has no way to let them know about issues so they can fix them.

Besides DirectX bug, In a 4 camera window I've had 3 windows now not connecting for up to 5 minutes. One connects immediately all the time. When the others finally connect, the video is choppy and not real time, like there is router connection issue. I've never had this and it only started with the client update. I connect real time using my android phone, both wifi and cell. I also connect on an old laptop with an old version of the client just fine. I also loaded v7.2.2.33+x64 from the Reolink site running in parallel on same laptop with v8.12.1 and it works fine.

What is the difference between E1 Pro IPC_515SD5 and IPC_513SD5. I just bought an E1 Pro and found it to be 513 which appears to be an old hardware platform and has no firmware updates. Not happy!
I also bought an E1 which will not stay connected to WiFi. Have tried everything. Other cameras are rock solid and used a wifi analyzer, seeing that the signal is very strong and solid. And yes, the camera is close to router until i get it to work. One note, my cameras are connected to a router wired as an access point connected to the main router.
