Common reasons for incrementing from Ts10.2.1 to Ts10.2.2

The most immediate change in TS10.2.2 is the fluidity of the User Interface (UI). Previous versions suffered from micro-stutters during app switching and menu navigation. This update introduces optimized memory management that is immediately noticeable.

: Support for 360-degree camera views, which sometimes requires a specific "ZT" system upgrade.

Video input format changed. Fix: Enter Factory Settings (password 8888 ) -> Other -> Camera type. Toggle between CVBS, AHD, and 720P until video returns. Note that Ts10.2.2 defaults to AHD for many users.

Make sure you backup your current firmware and MCU file before updating. I’ve seen a few people brick their units jumping from 9.x straight to 10.2.2.
