Megapixel cameras can offer image resolutions higher than broadcast HD resolution, and I think an explanation is in order. One could consider HD a subset of megapixel. HD is defined by specific resolutions at specific frame rates with a specific aspect ratio.
Is MP better than HD?
The key features of HD for video surveillance is: Maximum HD resolution is 2.1MP, maximum megapixel resolution is 20MP or more with 5MP cameras are common from numerous vendors. HD video format is 1280 x 720 or 1920 x 1080 (megapixel cameras can offer many more formats)
How many megapixel is HD?
Image sizes
There are two main resolutions for the HD specification, 720p (1280×720, just less than 1-megapixel) and 1080p (1920×1080, 2.1-megapixel).

Do more megapixels mean better photo quality?
The only thing more megapixels will give you is the ability to enlarge and crop pictures without individual pixels becoming visible. Other factors are much more important in determining overall picture quality. Megapixel resolution plays an important role in how large you can print your pictures.

Whilst megapixels aren’t the be-all and end-all for any camera purchase, they can provide a pretty good yardstick for overall image quality. 1.3 megapixels has positioned itself as industry standard, and for most users this will churn out acceptable performance.
What is an HD camera?
HD refers to cameras with a standardized resolution of 720p or 1080p. The numbers 720 and 1080 refer to the horizontal resolution.
Which is better 1080p or 16MP?
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 megapixels are good for a camera?
A decent 6-megapixel camera is good enough for most normal camera usage. Go for higher megapixels only if you wish to use your images for canvas-sized prints or large hoardings. If your interest is in night sky photography, then too a higher megapixel camera can be important.
Why megapixels are not important?
If anything, super-high-megapixel cameras perform worse in some situations than low-megapixel models. They tend to show more grain in low light and emphasize motion blur and focus errors. In fact, both cameras produce photos so large that I had to shrink them in order to make them fit on this web page.
Is 10 megapixel good enough?
A camera with 10-20 megapixels is going to, in most cases, be more than capable of meeting all your needs. You’d be served far better by saving money on your camera and investing in better lenses.

The above table gives a good indicator. Cameras in the 5 to 7 megapixel range make nice 8×10-inch prints. In choosing a camera in this range, all other thing being equal, I would probably choose a 5 megapixel camera over a 7 if the 5 megapixel camera’s pixels were significantly larger.
Is 0.3 MP better than 720p?
720p refers to video technology. 3mp is for still images. 720p is not even high definition and nowhere near 4K video quality. 3MP is very very low by today’s standards.
How good is 720p HD camera?
A 720p camera’s image is high enough quality to identify someone looking directly at the lens from across an average family room with good lighting. Real-life scenarios add another layer of complexity.
What is the difference between HD and VGA?
Full HD vs Standard VGA– you can literally multiply the horizontal and vertical lines of pixels to see how many pixels you get from each. In this case you’re looking at 2,073,600 total pixels vs 307,200 respectively. You are technically getting 6.75x more image definition.
Is 720p webcam good enough for zoom?
Even 720p is perfectly adequate for general video chat purposes – until the iPhone 7, it was the resolution for all iOS FaceTime calls.
