No, the HP webcam doesn't require the Simpo software to work. You just have to install the necessary drivers for the product, and it should work normally without errors. You can get the drivers for your product using the HP website.

Note: Input the model number or the serial number and then download the necessary software or, if you have a CD with drivers, install its contents, and the webcam can be used in any compatible application that supports webcam streams.
