The Basic Definition
A megapixel or MP is the equivalent of one million pixels. Each of those pixels will link up together to produce the images your IP cameras project.
The MP measurement specifically focuses on how many pixels are found in a square inch. Therefore, a 5-megapixel camera will produce a resolution of five million pixels in each square inch being projected.
Produce Precise Images
The most important part of the MP measurement is that it gives you a precise idea of what your images will look like. You can use the measurement to figure out how detailed your images might be.
A camera with more megapixels is a model that does not produce lots of motion blur or other difficult effects. It should be easier to see things with your camera when there are more megapixels involved.
How Many Do You Require?
Although you might consider a camera with as many megapixels as possible, that does not mean all IP cameras need to be fully loaded. A good idea is to look at the size of the image produced by your camera. The image should have enough megapixels to match up to its image size. A 5x7 camera would work well with a 4-megapixel resolution, while an 8x10 camera would operate better at 7 megapixels.
