Reposting since I accidentally deleted it and I can’t seem to restore it.
Wyze cameras require internet connectivity to connect to a NTP server to sync timestamps and recording date. If it can’t access to a NTP server, it will start recording files and timestamp based on the firmware date that was built. I took advantage of this to do the following test below.
Confirmed. I am able to recreate this as well on my Cam V3 on firmware 4.36.13.0416 by disabling my WiFi and power cycling the camera. On the microSD, recordings will have timestamp 2024-07-03 01:10 saved in the folder record > 20240703 > 01 > 10.mp4, 11.mp4, 12.mp4 and etc. After 5 minutes, I power cycled it again and checked the files on the micro SD and it did overwrite it (no “_new” file was added)
I manually flashed back to 4.36.11.8391 and redid the test above while my WiFi is disabled. On the microSD, recordings will have timestamp 2024-01-04 19:39:46 saved in the folder record > 20240104 > 19 > 39.mp4, 40.mp4, 41.mp4 and etc. After 5 minutes, I power cycled it again and it didn’t overwrite the files, but it added “_new” for each file. Out of curiosity, I power cycle the camera again to check if it will add another file like “_new2” for example, but I can confirm it didn’t and it actually overwrite the “_new” file instead. That means if I were to restart the camera again then it will only overwrite the “_new” file again. 39.mp4, 40.mp4, and 41.mp4 and etc are left untouched.
