As IP-based video systems continue to gain widespread popularity in the video surveillance market, one of the benefits is the ability to capture high-resolution images through megapixel video.

Because the terms HD and megapixel both indicate an improved level of imaging performance compared to traditional analog images, they are often thought to be the same. But, there is a difference.
