1080p is a fairly standard resolution for a decent webcam, but if you really want to up your picture quality (or be able to crop your frame and keep it sharp), you want a 4K webcam. Frame rate also affects how smooth your video looks.
For example, a 2 megapixel camera actually captures 1,920,000 pixels per frame. A 3 megapixel camera captures 3,145,728 pixels per frame.

If you want the best possible image quality, then a bigger sensor is more important than huge megapixel counts. But sure, if you're working on high-quality professional gigantic print jobs, or large framed prints, then 20 megapixels or more will be great.
As a general rule for most enthusiast photographers, 24 megapixels is more than enough for high quality printing and display on digital devices. 24 megapixels is the sweet spot for value and can produce a beautiful fine art print at 20 x 30 inches or a huge canvas print 60 inches wide.
According to scientist and photographer Dr. Roger Clark, the resolution of the human eye is 576 megapixels. That's huge when you compare it to the 12 megapixels of an iPhone 7's camera. But what does this mean, really?
While they necessitate expense beyond a laptop or PC, external webcams are apt to have higher quality components that allow for fine tuning. Embedded webcams are typically small; small components directly impact the level of camera performance and image quality. lens stack, so image quality may not be the best.
5MP Super HD security cameras, also known as 5MP security cameras, gain a resolution of 2560*1920. They are currently the mainstream in the security camera filed and deliver much clearer images than 1080p and 720p IP cameras.
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.
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. No specific system can capture every scene, but a higher-resolution security camera provides a slightly better chance of gathering an important detail.
720p (
1280×720 px; also called HD ready or standard HD) is a progressive HDTV signal format with 720 horizontal lines and an aspect ratio (AR) of 16:9, normally known as widescreen HDTV (1.78:1).

Its quality isn't much better than a 720p TV. 1080p has a resolution of 1920 by 1080 pixels. It's a progressive scan display rather than interlaced.

For example, 1920x1080, the most common desktop screen resolution, means that the screen displays 1920 pixels horizontally and 1080 pixels vertically.
The most commonly discussed 16K resolution is 15360 × 8640, which doubles the pixel count of 8K UHD in each dimension, for a total of four times as many pixels. This resolution has 132.7 megapixels, 16 times as many pixels as 4K resolution and 64 times as many pixels as 1080p resolution.

As we mentioned before, 12MP cameras usually allow for larger individual pixels than super high-resolution sensors. The larger the pixel size, the more light each pixel can capture. A 12MP half-inch sensor would produce far cleaner low light shots than a 48MP half-inch sensor, given that every other variable is equal.
Megapixel resolution plays an important role in how large you can print your pictures. Because the more megapixels you have, the more detail is recorded, high-resolution cameras allow you to make larger prints or crop shots without worrying about the image's pixel structure becoming visible.

The more the pixels, the bigger the image. And of course, the bigger the image, the more you can see (in most cases). A 64MP camera would take an image of 9216x6912 resolution for instance, which is much bigger than the 4032x3024 image that a 12MP camera would take. You get bigger pictures and logically, more detail.
Apple Megapixels don't matter anymore. But to look at most phone or camera ads you'd think they're the most important stat in the world.
The answer is yes. Megapixels always effect video quality in that the more megapixels the higher the resolution and therefore the better the quality. That being said, if you have a 4K video but watch on a screen which can only handle Full HD then you won't see the full 4K quality you've shot with.
5 megapixel cameras are not bad for taking selfies. However, if you are looking for better selfie camera performance, look for an 8/12 or higher megapixel camera with a large aperture. Megapixel count is not everything; the Pixel 2 has an 8 MP camera and still takes great images.
Another advantage of a high megapixel count is that you have more flexibility in post-production. So it can come in handy when you're cropping, retouching and compositing images. Generally speaking, the high megapixel count is important for fine art, landscape, and commercial product photographers.
The size of the image sensor is extremely important. In general, the larger the sensor, the larger your pixels, and the larger the pixels, the more light you can collect. Larger sensors are the reason that 8 megapixels from a digital SLR camera (or 5 or 13) best those 8 megapixels from a smartphone camera.
A very common resolution for printing an ad on a very large outdoor billboard is 1800 pixels on the long edge and 1200 pixels in height (about 15 dpi). That equates to a mere 2.1 megapixels.
A resolution to fit with your devices' screensFor a picture to be pinpoint sharp on a Full HD screen, its definition should be at least 1920 x 1080 pixels, or around 2.07 MP.
A camera with 18-megapixel resolution might sound insane. The higher the megapixel count, the more detail a camera can capture. It's not the only thing that one should consider when buying a digital camera, but it's a significant part of the equation.
Back in 2019, Fujifilm released its first entry into the 100-megapixel medium format camera space. It boasts a 44 x 33mm (that's larger than full-frame) sensor with a 102-megapixel resolution, but the cost has dropped to $6,000—and the camera is actually smaller than some full-frame mirrorless models out there.
