C1 PRO vs C2

12 Comments

Preparing to release new cameras and presenting comparison table. C2 camera is still based on Sonix chip-set and IMX290/1 sensor, but superior in many aspects. Most noticeable cosmetic changes are: size, integrated heat-sink and USB-C connector. However many other new features are hidden inside.

Below is comparison table:

    Does it support 30 FPS YUYV at 1080?
    • saulius
      Unfortunately USB2.0 is maxes out at 5FPS in YUYV mode at 1080 resolution.

    Great to see this comparison chart. I am very much looking forward to buying a Kurokesu camera.
    • saulius
      Glad to hear Ray! Actually samples from sample assembly can be already ordered. Documentation is still being prepared though.

    Why does C2 has still old usb 2.0 standard, as many customers would need usb 3 if they want to use multiple cameras on a USB hub, usb 2 is much to less bandwidth
    • saulius
      Alex, Sonix chipset supports only USB 2.0. Working on other designs, but so far these are not production ready.

    I've been using my C2 camera for over a month now. We are using it to stream and record online martial arts, exercise, and academic classes. So far, we very satisfied with its performance- the 2.8 to 12mm zoom lens we bought with it offers very good optical performance and a good zoom range. At its widest, its field-of-view is wide enough to cover the teaching area, and when we need to zoom in for tight shots, the 12mm offers plenty of zoom range. The camera's low light performance is very good- it surpasses our Logitech C920. I will post test results and a detailed report of our experiences!

      Thank you Collie! Will be waiting for review!

    Kurokesu, hi! In datasheet of chipset SN9C291B we can se support of 640x480 an 60 FPS (MJPG). What about support of this feature in you cameras? USB2.0 can easy transfer this rate. But, we need firmware support of this mode. It was bee greate update! High FPS (it doesn't matter what is in low resolution) is important in some cases, like a star tracking in telescope guidanse system.
    • saulius
      Hi, unfortunately I was assured by Sonix engineer that SN9C292 support 30fps max no mater what resolution is selected.

    Thank you for the honest answer! It's sad to hear that. It turns out that the Sonix datasheet is lying. The policy of manufacturers of microcircuits for cameras, of course, is depressing :( Nevertheless, could you please provide me firmware.bin for the C1-pro camera, which automatically adjusts the FPS depending on the illumination - i read that you can provide it by email. And again, thanks for your answer!

      Not necessary, in certain configurations sensor and SOC will have limited functionality. Please drop me an email with your order nr and camera SN.
