Logitech has introduced two new DualCams, the ClickSmart 310 and ClickSmart 510, in response to high consumer demand for a camera that quickly sends photos or videos electronically. The ClickSmart 510 offers a still resolution of up to 1.3 megapixels and contains a built-in microphone, automatic strobe flash, SmartMedia port and self-timer. With the included SmartMedia memory card, it can store up to 480 pictures or 90 seconds of video, and users can expand this capacity by purchasing additional memory cards. The ClickSmart 510 has an estimated retail price of $399. The ClickSmart 310 is a more affordable model that shares a lot of the features of the 510. It can store up to 160 photos and 15 seconds of video, and allows a still image resolution of up to 640x480 pixels. It is expected to retail for $199.
