If you are uncomfortable downloading drivers from third-party sites, you can let Windows find a generic driver automatically. Often, webcams like this use common chipsets.
A 4.8mm focal length on a small webcam sensor typically creates a standard-to-narrow field of view. It does not offer the ultra-wide angle view seen in specialized conference room cameras.
Because these specifications are common to hundreds of budget, unbranded factories (often manufactured in bulk and sold under various names on Amazon, eBay, or AliExpress), there is no single "F=2.0 f=4.8mm" official website. Why Most "F=2.0 f=4.8mm" Webcams Don't Need a Manual Driver

If you absolutely must find a specific driver, you need the , not the lens specs: Often, webcams like this use common chipsets
The F-number dictates how much light the lens lets in. An aperture of F/2.0 is relatively wide, meaning the camera performs adequately in moderate lighting. However, because generic sensors are small, image noise can still appear in dark environments.
This dictates the field of view. A 4.8mm lens on a standard small webcam sensor typically provides a narrow to moderate field of view, ideal for close-up headshots but not meant for wide-angle group meetings.
