For a couple of years, I've had my DR750S-2CH running happily with a Samsung 64GB EVO+ SD card (U1, Class 10). Recently the card failed, becoming unwritable, both in the camera and on my PC. The camera drew my attention to the problem with its "Check SD Card" notification. I expect cards to fail from time-to-time so no issues, I'll just replace it.
I have attempted to replace the card with a SanDisk Ultra 64GB A1 U1 Class 10 and with a SanDisk Extreme 128GB A2 U3 V30. In both cases, the camera is able to format the card, but does not record any video.
If I attempt to use LiveView through the mobile app, without being logged into BlackVue Cloud, it firstly displays a grey screen, after a few seconds the screen turns white, then pops up the message "Network connection failed". After a few seconds more, the camera reboots and connection is lost.
If I attempt to use LiveView through the mobile app, whilst being logged into BlackVue Cloud, the camera tells me that its starting LiveView but after about 20 seconds it pops up a "LiveView failed" message.
Note, the camera firmware version is 1.0.20, and that all other functions of the camera work perfectly. The camera is hardwired using power magic pro.
Can anyone advise on what I should do next to resolve my issue?
Thanks in advance,
