About
Reliable video conferencing is the backbone of modern professional communication. However, hardware specifications advertised by manufacturers often differ from actual browser performance due to driver bottlenecks, USB bandwidth limitations (e.g., USB 2.0 vs 3.0), or software throttling. This tool performs a granular hardware audit of your imaging device.
We bypass standard video abstractions to query the raw MediaStreamTrack settings. This allows us to determine the true maximum resolution - verifying if a 4K camera is actually delivering 2160p or being downscaled to 1080p. Furthermore, the integrated FPS (Frames Per Second) analyzer detects latency and frame drops that occur in low-light conditions, ensuring you don't discover hardware failures five minutes before a critical interview.
Formulas
To calculate the true data rate required for uncompressed video, we utilize the resolution dimensions, frame rate, and color depth. This explains why high-resolution webcams often require USB 3.0 connections to function without heavy compression artifacts.
Where W is width, H is height, and bpp (bits per pixel) is typically 24 for RGB video.
