As a general rule of thumb, the higher the resolution, the better the overall quality of the image. 4K security cameras offer superior image quality than 2K security cameras. With a higher resolution of 3840x2160 and at 8 megapixels, these cameras are currently the very high end of surveillance video quality.
Is a 4K Monitor/TV Required for 4K Security Systems. Technically speaking, it is recommended to use a 4K monitor/TV for your 4K security camera systems to avoid possible compatibility issues. And you can also obtain 2160p high resolution images to justify the cost the 8MP/4K security systems.
The Reolink 4K PoE Security Camera System lives up to its name with 4K Ultra HD video. This works out to a resolution of 3840 x 2160 pixels. As a result, you're looking at a very versatile camera.
4K ultra-HD security cameras offer superior image quality, color, and performance over 1080p security cameras. They provide up to four times higher image and video resolution than the standard 1080p. These ultra-HD security cameras have a resolution of 3840*2160 with over 8 million pixels.
4k video is a substantial step up from 1080p, with four times the resolution of 1080p; in a 16:9 ratio, that's 3,840 x 2,160 pixels compared to 1920 x 1080 pixels. On a screen, 4k video contains more than 8 million pixels compared to just 2 million pixels for 1080p.

As Mosswings said, 4K is 4000 X 2250 pixels in 16:9 video format, or 8.3MP. A 3:2 ratio image sensor that had 4000 horizontal pixels would have 2667 vertical pixels, or 10.7 megapixels. So you need an 10.7 + MP camera to shoot native 4K video.
A 4K TV is a TV set with 4K resolution. That means the TV has 3,840 horizontal pixels and 2,160 vertical pixels, for a total of about 8.3 million pixels. On TV product specifications, resolutions are usually shown as "3840 x 2160" for 4K TVs.
A 4K security camera has an 8MP image sensor that is double that of 2K 4MP, allowing video capture that is twice the resolution. With the increase in video resolution it produces a video that is 3840x2160 pixels that is also a substantial improvement over 1920x1080 pixels provided by 1080P.
The 5MP security cameras have better clarity than the low megapixel cameras, thanks to their improved resolution. For example, the 5MP IP camera is sure to be at least twice clearer than the 2MP (1080p) ones.
Part 1: Megapixel IP Security Cameras Explained
| Megapixel Cameras | Resolution | Camera Examples |
|---|
| 1MP Security Cameras | 1280*720 | — |
| 2 Megapixel Security Cameras | 1920*1080 | Reolink Argus 2 |

| 4 Megapixel Security Cameras | 2560*1440 | RLC-410W |
Also, the height of an image is used to symbolize the resolution and thus, you can say 1080p resolution when talking about an image with 2 million pixels. The most common resolution for home security camera in the market includes 2MP (1080p), 4MP (1440p), 5MP (1920p) and 8MP (4K/2160p).

Casual PhotographerFor prints, you're likely to print off standard 6x4 inch prints. If this is the case, you really don't need to be too concerned about the megapixel resolution of your camera. Most modern cameras fall somewhere between 16 MP and 60 MP, all of which are more than sufficient to meet your needs.
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.
High Video Quality: The video quality is 4K, which is among the best of the best for security cameras. People and Vehicle Detection: With advanced motion detectors, we were alerted when there was movement on our property.
IP cameras typically feature better picture quality, advanced recording features, and the capability of connecting a larger number of cameras to the system, when compared with the older CCTV systems. Videos are stored digitally using a network video recorder, or NVR, rather than a physical DVR.
4MP is 2x1080P.Although they both have 4 in the name, 4K is double the quality of 4MP. Note: If you are viewing this on a tablet or mobile phone, you may need to click the images to see them full-sized, as your phone may be downsizing them.
Generally speaking, the 2MP CCTV camera is enough for general purpose monitoring of the front door, backyard, or indoors, as I put it before. And the 4MP or 5MP cameras have more advantages in capturing the details at a distance.
