The introduction of H.264 compression has reduced the amount of bandwidth megapixel cameras use. The issue of bandwidth with HD and megapixel cameras is not what it once was. Instead of five cable pulls there is one - and only one time up the ladder, one camera to focus, one camera to maintain. Not only is this a savings on cameras but also cable, labor and any accessories needed for the camera installation. In this example it is possible to replace as many as five SD cameras with one megapixel camera.

#Mega pixels means 720p

Compare that with a 1.3MP or 720p camera at 25 ft., a 2MP or 1080p at 30 ft., 41 ft. With a SD camera the largest viewable area that maintains 50 pixels per foot is 10 ft. This typically requires 50 pixels per horizontal foot for a clear, readable image.

To illustrate this, consider the application of wanting to view license plates within a scene. How much you can zoom into the scene is determined by the area being viewed and the pixel density. This pixel density can allow the ability to zoom into the scene live or for forensic review, giving the system greater flexibility and performance. Because of the pixel density in this technology it is possible to look at large areas while maintaining the detail that would require multiple SD cameras. In the correct application HD and megapixel cameras can be of great advantage as well as cost effective. Also, HD has quality compliance standards to meet whereas megapixel simply specifies the number of pixels. This is squarer, like an older TV screen. In HD technology 1080p is the greatest pixel density but megapixel is available as high as 16MP.ДЄnother difference: HD has a 16:9 aspect ratio, which is a wide screen type view, whereas megapixel typically has a 4:3 aspect ratio. HD cameras are referenced as 720p (1MP) and 1080p (2MP). For instance, all HD cameras are megapixel but not all megapixel cameras are HD. There are many similarities but also some differences between the two. Within this technology there is megapixel and HD. This is considered a 2 megapixel (2MP) camera. Multiplying the horizontal and vertical pixel count and dividing the result by 1,000,000 will yield the total pixel count expressed in megapixels. The typical SD camera has about 400,000 pixels, whereas a megapixel camera has a minimum of 1,000,000 pixels. The pixel count is important in determining the correct camera for an application. The higher the pixel count the greater the density of pixels on the sensor.
