And yet another glitch/follow-up: while you can access the camera's web interface, you can not direct the NAS recording output to a NAS - it appears to locked in to a Windows Appdata hidden directory, no matter where you direct it in the camera's web interface settings. And they no longer record to the SD card - so there's no way to use them for anything other than live viewing on your phone. And, of course, there's no sign of life from Lorex's "technical Support"!
I guess its time to replace them all with Eufys.
