  • 4K Ultra HD at 3840×2160 resolution for studio-grade streaming
  • 10× optical zoom with 5–50 mm varifocal lens for flexible framing
  • Sony IMX415 sensor with IR-cut filter at 650 nm for true colour
  • Manual focus, iris and focal-length control for precise image tuning

Built for specialist imaging

The Avantalk 4K webcam delivers 3840x2160 resolution at 30 fps through a Sony IMX415 sensor and a 5-50 mm varifocal lens. Its 10X optical zoom and manual focus, iris and focal-length controls suit studio photography, live streaming, machine vision and medical imaging. A 16:9 aspect ratio and IR-cut filter at 650 nm complete the feature set.

USB connectivity and mounting

The camera connects over USB and fits a standard 1/4-inch tripod thread or regular webcam stand. It requires host software and a display that support 3840x2160 output; some applications limit capture to 1080 or 720 resolution. No internal storage or battery is present, so a powered host is essential for continuous operation.

Passive thermal design

The mini aluminium enclosure dissipates heat without a fan, ensuring silent operation during extended sessions. Power draw is limited to the USB bus, keeping cabling simple and avoiding extra adapters. The IR-cut filter maintains colour accuracy under varying lighting without active cooling.

Questions about this item

How long can the 10X optical zoom lens maintain focus before manual re-adjustment is needed during a full-day stream?

The 5-50mm CS-mount lens requires manual focus, iris and focal-length adjustment; there is no auto-focus motor, so any thermal drift or subject movement means you must re-adjust by hand whenever the image softens.

Does the aluminium body stay cool and silent when the Sony IMX415 sensor runs at 3840x2160 30fps for hours?

The mini aluminium case has no fan and no active cooling mentioned; it relies on passive dissipation, so surface temperature will rise during sustained 4K capture and the unit remains silent because there are no moving parts.

What host connection and software capability are required to actually see 4K 30fps from this USB camcorder?

You need a USB port that supports the necessary bandwidth plus an operating system and application that can decode 3840x2160 30fps MJPEG; the supplier notes some software and screens only handle 1080P or 720P.
