I'd been considering getting a webcam for my parents but it needed to have a built-in mic and work out-of-the-box under Linux with Skype. A search on Amazon for 'webcam linux' immediately brought up this surprise offering and I'd completed the order a couple of minutes later. It arrived within two days and works fine. No faff or need to scour other products for hours on end.
The system it's set up on is the same openSUSE 11.2 using the identical Skype version mentioned by the previous reviewer, which is what convinced me to buy it. However, unlike their experience, the LED lights work fine using the small wheel controller on the cable (similar to the extra volume control you find on earphone cables). Focus can be adjusted by turning the ring on the front and the device comfortably straddles the chunky top of my parents' LCD monitor, but will also rest on its base elsewhere. The button on the top (I assume for taking a snapshot) doesn't do anything but maybe that depends on the software being used. The picture seems very clear and the mic works.
I don't know exactly what kind of generic / unbranded model this is and it arrived on its own in a jiffy bag, but the seller has obviously cottoned on to a massive opportunity for Linux users who just want to buy a webcam that they can be sure is properly supported with no fussing about. This should be a signal to all the other manufacturers who are too lazy or ignorant to test, fund or advertise Linux compatibility on their products, that they're losing customers! Having already purchased two expensive and obscure webcams with vague specifications only to find they both use proprietary Windows-only drivers, I've had my fingers burnt already. And for the price this product is a bargain. I expect and hope the seller will make a killing on this and any other products they can source and advertise as 'for Linux'.
I would purchase a second for myself, but the only drawback I can find is that where the cable splits in two for the USB and mic connectors, there's only a short length from there on, meaning it would be no good on my laptop since it has those two sockets on opposite sides, too far apart. A small audio or USB extension cable would fix that but I'd rather just have the audio going through the same USB connector and showing up as a separate input in my mixer.
I would say if you are a Linux user looking for a good value cam, buy this and show your support for clearly labelled Linux-compatible products!
