HD cameras are referenced as 720p (1MP) and 1080p (2MP). In HD technology 1080p is the greatest pixel density but megapixel is available as high as 16MP. Another difference: HD has a 16:9 aspect ratio, which is a wide screen type view, whereas megapixel typically has a 4:3 aspect ratio.
What is 3mp resolution?
3MP IP Security Cameras
3 Megapixel Security Cameras are network based surveillance cameras that provide video resolution of 2048 x 1536 pixels over a digital signal using CAT5e/CAT6 cabling.
Is 5 megapixel better than 1080p?
Therefore, 720p HD camera resolution provides images that are 1280 x 720 pixels (that adds up to 921,600 pixels, which means a 720p HD camera is not technically a megapixel camera), and 1080p HD cameras provide 1920 x 1080-pixel resolution, or 2.1 megapixels.
