As high definition (HD) becomes the norm in the video surveillance industry, there is the growing propensity to describe video produced by these modern security cameras as high definition or megapixel images (in fact, a market research company predicts that more than half the network cameras shipped by 2014 will be offering high-definition or megapixel resolution).

The interesting aspect is that both of these terms are used interchangeably, which while seems logical is certainly not technically correct. In an elaborate article on SourceSecurity.com, Raul Calderon of Arecont Vision which makes megapixel IP security cameras, explains the differences between megapixel and high-definition resolution.

While getting a clear understanding of the differences will be immensely useful for those who are planning to install high-spec security cameras for their surveillance needs, it needs to be remembered that options galore. As the writer mentions in the article mentioned above: “Whether you prefer megapixel cameras or its subset HD based on your specific needs, the wide range of high resolution cameras today provides a powerful palette of imaging tools for industry professionals. It’s crystal clear that better systems are a direct result of the superior imaging possible with these high-resolution camera technologies.”
