The seller declares it as a 5M HD camera, but probably nobody would even believe it. Lens frame lies even more, and declares that it is an 8.0 Megapixel camera. I was interested how well it performs and what is inside.

Board Lens You can see that the IR block filter is part of lenses. I did not try to remove it yet, but it seems to be the topmost element. USB identification USB id: 1908:2311 idVendor=1908 (GEMBIRD) idProduct=2311 Product: USB2.0 PC CAMERA Manufacturer: Generic SerialNumber: 0203 uvcvideo: UVC 1.00 device USB2.0 PC CAMERA (1908:2311) input: USB2.0 PC CAMERA Camera is an UVC standard camera and supports up to 640×480 at 30 fps. So it is 0.3MPix in the fact. The camera can produce YUV output only. Chemical kinetics and reaction mechanisms espenson pdf the best free software f.

(It is not a problem for the most of the recent software.) Supported resolutions: 640×480, 352×288 (seems to have stability problems), 320×240, 176×144, 160×120 Supported FPS: 30fps, 15fps Supported controls: brightness, contrast, saturation, hue, power line frequency, gamma sharpness, backlight compensation It reports itself not only as a camera, but also as an input device. It means that the chip probably supports button. Analysis The camera has a very low field of view (horizontal field of view is approximately 24°), but the image is a pretty sharp and colors are good. Lens holder is pretty large and has a long thread. If it is unscrewed as much as possible, it can be turned to a cheap microscope. But you need to remove the cover for this purpose, as it makes impossible to unscrew so much. The camera has no microphone (and also no hole in the case you can see on the listing photos).

The whole board consists from a single IC, CMOS sensor itself and a few parts. There is apparently a space for LED light and one IC (USB id memory?). If you use the camera without the case, protect it from strong sidelight. It can cause reflections of PCB traces directly to the sensor. Board revision: AX2311-BC-0309-6DBY-001 CMOS sensor The CMOS sensor is a 640x480@30fps 1/9″ sensor with pixel array size 648×488 pixels (). It has a very good sensitivity in the infrared range, so it could be used for infrared experiments.

USB controller The USB controller is labeled with an logo and letters: 2311-A4F EAPR28193_1 1412ARZ. Guessing from the PCB print, it is an AppoTech AX2311.

But it does not help at all. There is no single reference to such part anywhere on the net.

Examples Indoor Standard conditions Low light Web camera video playback (If the video does not play to you, download video.) Used as microscope This example was made with camera open, microscope slide lying on top of the lens frame. The limiting factor was the height of the frame, not the thread length. Long term experience It is not suitable for 24/7 use. The firmware is a bit flaky, and freezes about once a week.

You need to unplug and plug again to get it working again. Summary If you expect a decent 640×480, it is definitely a good deal. Pros • Cheap • Small • Decent image quality • Low FOV (well, it is good only for somebody) • Can be probably transformed to IR camera • Lens are deep behind the lens frame edge, which protects them from scratches and accidental touching. • Auto white balance performs indoor well. Cons • 640×480 pixels is a basic resolution • 30 fps is not so much • Low FOV (well, it is bad only for somebody) • Lens are deep behind the lens frame edge, which causes problems when trying to attach to an eyepiece of a microscope or telescope. • Exposition automatics avarages the whole frame in a non-optimal way. If the image from microscope or telescope covers only the image center, it is overexposed.

• Exposition automatic could be a bit faster. • Unstable firmware.
