Sorry i still do understand what's the 'sensor' or 'sensor mode' you're referring to. The camera's sensors are built-in components that directly support its core features and overall performance. They can't be adjusted directly, nor do they have independent control options.
It seems your inquriy has something to do with the camera day and night mode? Why don't you describe the problem you've encountered directly in details? For example, is the camera has trouble switching to the night mode (infrared mode) automatically when it is dark? Is the camera not switching to the night mode even when you manually switches it? Where did you adjust the settings? Please post a screenshot here to show which feature option did you use.
