There are a few reasons why you might want to downgrade your EZVIZ device's firmware:
Note: This works for most Ezviz cameras that use Hikvision's underlying protocol.
Official EZVIZ policy states that for security reasons, no official downgrade methods are provided
: Format a microSD card (16GB or 32GB is ideal) to FAT32 .
Simply power on the camera with the SD card inserted. Some models automatically check the SD root for digicap.dav on boot.
The EZVIZ mobile app always pushes the latest version. For a downgrade, you must manually source an older .dav or .bin firmware file.
