Good Camera Build No. 18122101 Firmware 1221_246_237_23
Other Build No. 18073001 Firmware 0730_135_134_24

The Camera that works good is 1221_246_237_23. the other one is 0730_135_134_24.

I to have a pair of Argus's, bought at the same time. Different build numbers, different firmware versions. One works flawlessly, one repeatedly loses its Preferred DNS setting. Wont push alarms or upload to the cloud. When checking for updates both are up to date. Customer Service never responded.
