Hi,
The video quality of a camera is influenced not only by the camera itself but also by the installation environment. Factors such as installation height, monitoring area, and ambient lighting play significant roles. Generally, we recommend positioning cameras in locations with uniform lighting, at reasonable heights, and with a clear view of the monitoring area, avoiding overly complex elements in the frame (such as dense vegetation). Due to these varying factors, even cameras of the same model can exhibit slight differences in video quality when installed in different environments.

From the video footage you provided, it appears that all other cameras are functioning normally, but the video named "1756182073417_0" shows issues with video quality. We analyze that this problem is likely due to a hardware malfunction. Therefore, we suggest that you contact your retailer or our local team to check if the specific camera is under warranty.
Usually, you can contact the online retailer to check if the camera is still under warranty if you purchased it from an online store. If you can't contact your retailer, please try contacting our local support team for further assistance.

Best Regards
