[11h] Add error handling (ПП: камеры периодически отваливаются, видео по таймспану не отображается, решение: внедрить обработку ошибок)

这个 Issue 没有描述。

The issue mentions cameras periodically failing and video not displaying for a time span, requiring error handling. Start by examining the video monitoring and camera integration modules in the codebase. Look for existing error handling around camera connections and video retrieval. Determine what 'implement error handling' entails—whether it's adding try-except blocks, logging, retry logic, or user notifications. Check for related tests to understand the expected behavior.
