Power Data USB PC Webcam w/ LED Light	PRODUCT DETAILS (advertised) Features This unique webcam can sense the need for lightning by using infra-red light sensing technology. It has a very small sensor at the back of the webcam to automatically adjust the intensity of the shinning white light as required. The light will turn off itself as soon as the sensor detected there is enough natural light present. This eliminate the need to use overhead light in dark conditions for the other end to see you properly. It also has a manual switch to control the intensity of the light to fine tune the settings. This webcam provides clear white light and is proved to be the most effective kind of light for this purpose. The 380K cmos sensor ensure clear and high quality picture.

Conclusion: In my opinion, the Power Data webcam produced a more "true to color" image then the Logitech webcam. Features like auto lighting with the four LED lights in the Power Data's head and auto focus (limited ability) make this a far superior webcam then the Logitech with manual focus. The absence of a microphone was a slight drawback, but the image clarity and color soon made me forget about that.
