In most cases, Wyze wired cameras needs to first establish an internet connection with a NTP server to provide the proper timestamp and record into the correct folders. Wyze’s app relies the recordings being in the correct folder to align the footage chronologically. If it can’t establish an internet connection to a NTP server, then it will start recording into a random folder with a random timestamp. Your only choice will be then to physically remove the micro SD to view the footage in a PC or phone.
Cam V3 / V3 Pro / Cam Pan V2 with firmware 4.xx.13.0416 or newer will start recording into another folder with a incorrect timestamp after 30 minutes of internet outage (not power cycled). Flashing that firmware will cause it to act exactly like the Cam OG cameras.
In comparison, the older firmware of 4.xx.11.8391 can playback without any problem (under the same condition). Although it will still record properly after 30 min of internet outage, if you power cycle them (without internet) then the recordings start saving in a randomly generated dated folder with a incorrect timestamp (this is is expected behaviour).
To work around this issue, you can enable local NTP server and intercept NTP client requests on your Asus router in Advanced Settings > Administration > System > under Basic Config. Set your timezone and your choice of NTP server link (ex. pool.ntp.org).
This will allow your Wyze cameras to establish and sync timestamps with your router so it will record properly (footage in proper folders) even when the internet is down or power cycled / surge (without internet). The Wyze app now should be able to playback the footage without issue even in the event of an internet outage and power surge.
