The Chat and Show function
Indeed with this function, you can quickly show photos to your friends. It’s very simple and all you have to do is select one or several photos on the hard drive and launch the slideshow. Webcam video is automatically set in « picture in picture » mode so that you can still be visible while photos are shown. It’s also possible to move the slideshow by a “click and drag” of your mouse, reduce/increase its size using the mouse scroll wheel, or even choose to just show photos. Chat and Show can be practical in certain situations; however, the major downside is that the quality of images is poor due to the video format of instant messaging. It is therefore impossible to see precise details in images.

For the design, the manufacturer didn’t change anything compared to the previous Dualpix. It still has a sober plastic body and the webcam is as easily positioned on an LCD or CRT monitor. One small disappointment is that the manufacturer still hasn’t added an autofocus, which, we remind you, cost this webcam’s smaller sibling a star.
Very nice image quality
Once again, Hercules has come up with a very fine product. Certain webcams have problems with image rates and there can be fluidity issues when the user moves. The Dualpix Chat and Show is immune from this defect. The image rate is very good even in poorly lit situations. Otherwise, face tracking is efficient. We didn’t note any latency when the subject moved and the image immediately reframed him/her.
Once again color rendering was very good. We didn’t note any dominance as we have seen with certain rivals. Moreover, sharpness was excellent. The only big disappointment is that this webcam does not have auto focus. It’s true that we do not spend our time adjusting this parameter; however, we may move away from the peripheral and for this it’s best to have someone else on hand or really long arms to help in properly adjusting this setting.Will your voice be recognized?
In instant messaging conversations, we did indeed recognize the speaker. On the other hand, audio quality was not the best. Sound is slightly muffled and so we tested the external microphone that comes with the package. Quality was better but the sound levels weren’t high enough. In addition, after having pushed microphone sensitivity to the maximum, it was subject to blowing sounds coming from our voice.

Sound quality

The Dualpix Chat and Show offers, in addition to very good display quality, a slide show function. There was, however, the same degradation of sound found in other models and an auto focus which is still lacking.
