Hi,
Actually we were not doing a research we both wanted a working CCTV system that's functional & within budget (money & time)
In my opinion, it's all about functionality in the real world.
Why do we use MJPEG in the first place?
Did you compare picture in a computer screen with the image in an analog monitor?
In real life we need to compromise to get things done - specially if the effect is not relevant to the function.
Peace
