Color cameras have a monochrome (black and white) mode, but there are also pure monochrome cameras (black and white cameras).
The monochrome mode of a color camera is usually converting a color image to monochrome.
So what are the advantages of a pure monochrome camera? In general, monochrome is more sensitive than color cameras.
The high sensitivity is advantageous for adjusting the shutter speed and depth of focus. They also have different wavelength sensitivity characteristics. The sensitivity of the sensor itself can also change significantly.

However, color cameras often have built-in filters that cut wavelengths at around 650 nm.
