When people think of security cameras, they picture the grainy, almost unusable footage from a convenience store robbery. Today’s surveillance cameras have improved exponentially, with resolutions at high-definition or even 4K. Some high-tech security cameras can reach a resolution as high as 12 megapixels and offer multiple lenses with panoramic views from 180- to 360-degree coverage. Today's current crop of security cameras can capture the incredible detail of whatever is in their field of view. While we generally see cameras as a way to ward off or catch intruders, a well-planned security surveillance system can provide peace of mind in several other ways.
