The specs on the Intex say it is 8 megapixels (3264x2448) interpolated, not native. In fact, they do not even say what the native resolution is so you cannot compare it to the other.
Also, it is not clear if it has a built-in microphone or not.
Yes you are right about comparison, It has internal mic as per reviews.
I did not get the term interpolated,
u mean logitech's resolution (1.3MP) is native whereas there is nothing like this in intex ?
so as per your suggestion which is better out of these two?
