I have 5 410's, 2 411's, and 1 423. They all seem to lose their time settings and often. I have double checked all the settings, all cameras took their respective firmware updates with no issues. All cameras are connected via POE switch, the video stream is great, the interface is good, and no issues with night vision or motion/recording. Just the dang time settings.

Thank you - The time was off on the POE switch. Issue has been resolved.

Thank you for your information. I found the problem. POE Switch had wrong time set. Once I corrected that, its been about 8 hours and not one of the cameras has lost its time. Woohoo!
