How many megapixels is good for a security camera?
If you’re looking for a security camera, you may be wondering how many megapixels you need. In this blog post, we’ll answer that question and give you some things to consider when choosing a security camera.
When it comes to megapixels, more is not always better. A camera with too many megapixels can result in grainy images, while a camera with too few megapixels may not provide the level of detail you need. The sweet spot for most security cameras is between 2 and 4 megapixels.
When choosing a security camera, there are other factors to consider in addition to megapixels. For example, you’ll want to make sure the camera has night vision and is weatherproof if you plan to use it outdoors. You’ll also want to consider the field of view and storage options.
We hope this blog post has helped you understand how many megapixels you need for a security camera. If you have any additional questions, please feel free to contact us.

#1. Choose 2-Megapixel (or Higher) IP Cameras for License Plate and Face Recognition. If you want to capture license plates and recognize people’s faces, buy at least 2-megapixel security cameras  based on the multiple tests of our R&D team. [1]
4K Ultra HD Security Cameras When comparing 4K security cameras vs 1080p cameras, it’s clear that 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.6 Jan 2020 [2]
1080p vs. 3MP/4MP/4K IP security cameras: 3MP, 4MP, 4K and higher megapixel security cameras will provide higher resolution images and wider coverage than 2MP Full HD (1080p) IP security cameras, but more storage space and bandwidth are also required. [3]
8MP is a sensible minimum for big prints and 4K TVs, and even higher resolutions allow you to crop photos without sacrificing quality too much. However, make sure that very high resolutions are matched by an equivalent increase in sensor size.19 Sept 2013 [4]
Higher resolution offers greater detail, but also comprises more memory. A one-hour 1080p recording uses 675 mb (megabytes) of space, while the same video at 720p consumes only 288 mb. It’s important to have enough storage to cover the longest length of time you’ll be away from home.16 Mar 2021 [5]
The comparison of 1080p vs 1440p is that 1440p resolution doubles the pixels of 1080p (4) and enables the user to enjoy more sharpness accuracy (1) while simultaneously being able to experience much higher refresh rates. [6]
As you can see, by bumping up the resolution to 1440p, the PPI drastically increases, resulting in better sharpness. This is the key difference between 1080p and 1440p displays. If the display size is always the same, 1440p will always be sharper.28 Oct 2021 [7]
Conclusion
As it turns out, megapixels aren’t everything when it comes to security cameras. While a higher megapixel count will give you a clearer image, it’s not necessarily the best indicator of a good security camera. There are other factors to consider, such as the camera’s field of view, night vision, and resolution. So before you go and buy the biggest and baddest security camera on the market, make sure you know what you’re looking for.
