When it comes to megapixel counts in security video surveillance cameras, it’s important to resist the marketing claims that “more is always better,” notes Aaron Saks, senior technical marketing and training manager, Hanwha Vision America, Teaneck, N.J. “Over the past couple of years, megapixel totals have been increasing but the focus should be on having better, or more effective, megapixels and not just simply more.”

Here is an overview of some new functions and features that make modern megapixel cameras the most advanced of their kind.
