@C_G25 

Thank you for your post. 

1. We upgraded a C230I mini from 2.0.1 to 2.2.0 and triggered human- and vehicle-shape events; alarms were generated normally and the APP received the notifications.

2. At this stage we suspect that, after the upgrade, objects in the captured scene are no longer being detected. Could you please help us collect the following details so we can narrow down the issue?

1) Exact camera mounting position: height, tilt angle, and a description of the monitored scene.
2) Event-configuration settings: are you using the Smart Event “Human” and “Vehicle” toggles, or is standard motion detection (or another smart event) enabled with the “human/vehicle enhancement” box checked?
3) If “detection range has become limited” means the effective detection distance has shortened, please provide a rough before-vs-after diagram showing how far the camera could detect previously versus how far it can detect after the new firmware.
4) When you say “it no longer detects people and vehicles like before (even when it does detect),” do you mean the camera still detects but the APP no longer pushes messages? Do other alarm actions still work (e.g., audible alarm)? Actual recorded video from the camera would be even better.
