Product scope

The DIVI 4K Webcam delivers 3840x2160 resolution at 30 frames per second using a Sony IMX317 sensor and a 2.8-12mm manual varifocal lens. It connects through USB 2.0 and works with Windows, Mac, Linux and Raspberry Pi systems for streaming, conferencing or machine-vision tasks.

Sustained operation

The camera draws 200 mA at 5 V and is rated for continuous use between 0 °C and 60 °C with an electronic rolling shutter. MJPEG compression keeps the data rate within the USB 2.0 bandwidth limit during long sessions.

Setup checks

Verify that your host has a USB 2.0 port able to supply 5 V at 200 mA and that the recording software can decode MJPEG at 3840x2160. The 38 mm square body needs a flat mounting surface and the manual focus ring must be accessible after installation.

Questions about this item

How much power does the USB 2.0 webcam draw when running continuously at 3840x2160@30fps?

The camera operates at DC5V and 200mA, so it draws about 1 watt during all-day use.

What host connection is required for the camera to function?

A USB 2.0 High Speed port on a Mac, Windows, Linux or Raspberry Pi device is needed for plug-and-play operation.

Will the manual varifocal lens work with older 1080p-only conferencing software?

Yes, the sensor supports 1920x1080@30fps MJPEG and YUY2, so legacy apps can use the camera at lower resolutions.
