What this webcam does and who it suits

The UGREEN 55721 delivers 2K resolution at 30 frames per second through a USB 2.0 connection. A 4‑megapixel CMOS sensor and fixed‑focus optics provide clear video for meetings, streaming or online teaching. Dual integrated microphones capture voice while reducing background noise. A built‑in privacy cover and 360‑degree rotation add convenience for home or office setups.

Behaviour during long sessions

The camera maintains its 2K 30FPS output as long as the host system, monitor, USB bandwidth and software all support that resolution. Fixed focus performs best when the subject is farther than 50 centimetres from the lens. Digital scaling handles lower resolutions such as 1080P without driver installation, so extended calls stay stable without software overhead.

Thermals noise and power draw

Power comes entirely from the USB 2.0 port, so no external adapter is required and heat output remains minimal. The microphone array operates without a cooling fan, keeping acoustic noise at the level of the surrounding room. The lightweight body and simple mount add negligible load to a monitor or tripod during normal use.

Questions about this item

Does the USB 2.0 interface limit power draw or heat during all-day streaming?

The webcam runs on USB 2.0 bus power with a lightweight build and fixed-focus optics, so it stays cool and draws minimal current even during extended sessions.

What does the buyer need to already own for the 2K 30FPS image to work?

A computer with a USB 2.0 Type-A port, a monitor or software that supports 1440-pixel resolution, and an operating system that recognises UVC devices for driver-free operation.

Will the 95° field of view and fixed focus work well with an older 1080P monitor?

Yes — the camera down-scales to 1080P at 30 FPS, the 95° FOV remains unchanged, and fixed focus is calibrated for distances beyond 50 cm, so older displays show the full wide angle without refocusing.
