Megapixel Applications
While megapixel cameras provide an array of outstanding advantages, it's important to recognize that not every surveillance application requires this type of increased functionality. So how do you know if megapixel cameras
are right for you?
The first step is to have a clear understanding of the priorities and goals for your video surveillance system. What is its primary purpose? Will you need to review visual data following an incident? Is sharp detail important? Will you need to enlarge small areas of an image, such as a person's face or the license plate on a car? Once you clarify your goals, you can assess whether megapixel cameras are appropriate for your needs.
General surveillance is primarily live viewing - where details are not recorded for later review. Examples of this are traffic flow or crowd control. In the former, it's important to monitor traffic jams but there's no need to know the vehicle's model or license plate. And with crowd control, the aim is to ensure smooth flow or notice if someone wanders into an unauthorized area, but it's not necessary to recognize individual faces. These added levels of detail are usually part of forensic applications.
Forensic surveillance means that you monitor, record, and later view recorded images. The ability to enlarge portions for details like vehicle license plates and facial recognition is crucial. High security venues such as banks, casinos, ATMs, and retail stores use forensic surveillance to aid law enforcement investigations, so it's vital that images are detailed and crisp enough to see what happened, who, and what was involved. The clarity and sharpness available viewing zoomed images are the key benefits of megapixel technology.
