Realsense D457 needs any additional equipment to work?
I would like to know if the D457 camera requires any additional components to operate.
In the description of the camera it is mentioned: 'A Maxim de-serializer is needed at host side to decode the streams.'
And I wanted to know if this deserializer is necessary for all the functions of the camera, and if not, what would be the limitations of not having the deserializer.

By default the D457 camera model operates as a MIPI camera that requires a compatible deserializer product to be purchased separately (a popular choice is one from a company called Leopard Imaging) and also a special software driver. The camera will not function on a GMSL/FAKRA cable connection without these.
However, if you purchase a D457-compatible computer system from the company Connect Tech then it is not necessary to purchase the deserializer as the necessary technology is included in their product. They also provide a driver.
Further Information about the subjects mentioned above can be found at the following links.

If a physical switch in the D457's casing is moved sidewards though then the camera can use a USB cable connection like the other cameras in the RealSense 400 Series range and be detected as the D455 model. When switched into USB mode, a deserializer board and the special driver are not required and the camera works when simply inserted into a USB port.
If you have no plans to use the MIPI functionality then a D456 camera would be an appropriate alternative choice, as it behaves as a D455 and has the same protection against water and dust as D457.
