What many people do not realize is that there is another class of security camera that is directly available to the public, though not found in the big box and warehouse stores. These surveillance cameras are classified as "commercial-grade" security cameras and are the type of camera used by these big box chains to secure their inventory. Look at the ceiling of consumer electronics stores and warehouse chains and you will notice in each aisle a white dome camera that is larger than the average consumer camera. Let that sink in for a moment…these companies do not even use the type of cameras they are selling to the public, and there is a good reason why.
