Sometimes, cameras will automatically switch to night vision mode in low light conditions, displaying images in black and white. If automatic switching does not occur, manual operation is possible.

Specific steps to enable or disable the night vision feature on a camera may vary depending on the camera model and manufacturer. Here are some general steps:

Open the camera application.
Locate the camera device for which you wish to set the night vision mode in the application.
Click on the device to access its detailed page.
On the detailed page, there is typically an option like "Night Vision Mode," click to enter.
In the night vision mode setting page, you can choose to enable or disable the night vision mode.

Note:

To use the camera's night vision mode properly, avoid covering the camera's indicator light with tape, as the indicator light is needed to provide infrared illumination in infrared mode.
Most cameras are designed to switch to color mode in bright light conditions to prevent damage to the camera's night vision module.
Some cameras do not provide a night vision switch, so the night vision function can only be automatically turned on or off.
