  • 8-12mm manual varifocal lens gives precise 4X optical zoom control
  • 4K resolution from 1/2.8" IMX415 sensor delivers low-latency ultra HD video

Dual-Output 4K Webcam

The Avantalk camera delivers simultaneous HDMI and USB Type-C video output, letting educators and streamers feed a local display and a capture device at the same time. It draws power over USB-C and works driver-free on Windows, macOS, Linux and Android. The 1/2.8" IMX415 sensor produces 3840x2160 resolution at 30 fps with low latency.

Manual 4X Zoom Upgrade

The 2.8-12 mm varifocal lens replaces fixed-focus webcams by giving hands-on control of zoom, focus and aperture, with locking screws to hold the setting. The jump is worth it when a presenter must shift between wide room views and tight document close-ups without moving the camera. Preview software initialises in roughly eight seconds.

Flexible Encoding Headroom

H.264, H.265 and MJPEG formats are selectable, each supporting 3840x2160 at 30 fps, while 1080p at 30 fps remains available for lower-bandwidth calls. The multi-codec pipeline handles live streaming, video conferencing and local recording concurrently. Bandwidth-limited networks or older capture hardware that cannot ingest 4K streams mark the practical ceiling.

Questions about this item

What power and video connections does the Avantalk 4K camera need for simultaneous HDMI and USB output?

It requires a USB Type-C power supply and provides both Type-C and HDMI outputs at the same time for display or capture.

How do I set and secure the 2.8-12mm manual zoom lens on this camera?

Turn the lens barrel to zoom and focus, adjust the aperture for brightness, then tighten the locking screws on the lens to hold the position.

When will the IMX415 sensor need cleaning or the lens mechanism need re-lubrication?

Clean the sensor with a blower or microfiber cloth when dust appears in the image; the manual focus helicoid generally needs no lubrication unless it becomes stiff.
