Just thought I add more recent experience. It’s now been 8 days (8:13PM on 8/10/21) since receiving the last motion event notification from my V2 - with absolutely none since then. And before anyone asks there are literally hundreds of motion events captured on the local SD card.
Camera has been off/on/off/on cycled via the app so many times I can’t even begin to guess how many that might be. Likewise with removing/restoring power by unplugging the power cord.
Certainly glad I have other manufacturer’s cameras covering the same area that send proper notifications.
