2K vs 4K Security Cameras

In the security industry, you can judge security cameras in a number of different ways. Speed, costs, and capabilities are a few, but the leading point of reference is the resolution specs. Resolution is simply a way to measure the size of the video or the image. Smaller images produce lower resolution video, while larger images produce HD or high definition video. 

And, when choosing what one would call a decent security system, it’s important to know what the resolution specs are. It’s also good to see whether they meet your needs in regards to large areas vs smaller offices. 

Security camera resolutions are getting better every year. Although the accepted standard for most security cameras has been 1080p resolution, more companies in the surveillance industry are offering 2K and 4K video resolutions. 

In order to get a better idea of what all of this means, and in turn make better choices, one needs to take a look into each type:

Breaking It Down – Standard Resolutions VS Newer Advanced Models 

As a general rule of thumb, the higher the resolution, the better the overall quality of the image. Because of this, camera types have steadily been getting better and better. And the two leaders in this industry at the moment are 2K and 4K camera systems.

2K Super HD Security Cameras


Going beyond the conventional 1080p resolutions, 2K security cameras provide a video resolution of 2560×1440 with a 4 megapixel (MP) image sensor. In comparison to today’s competitive security camera industry, these super cameras deliver much clearer and sharper images. They also come with better quality videos than 1080p and 720p security cameras.

Another important point is that 2K HD cameras tend to offer a wider field of range. This makes them the preferred choice for larger areas.

4K Super HD Security Cameras

By comparison, 4K security cameras offer superior image quality over their older 2K competitors. With a higher resolution of 3840×2160 and at 8 megapixels, these cameras are currently at the very high end of surveillance video quality, also going one up on 2K they can sufficiently capture a much larger area.  However, this being said, 4K security cameras tend to require more bandwidth, and storing their footage requires more space than with 2K cameras.

A Time And Place For Everything – When to Choose Your K Series Security Camera And Why

Deciding which security system will best suit you can be as beneficial as the system itself. As theft and threat can sometimes be circumstantial, one should always try and take it into consideration. 

Some important things to keep in mind when choosing your k series system include:

2K Security Cameras

  • If you are in need of high-quality images with clear details from a distance.
  • When your place of work has been evaluated and 1440p resolution is enough for your video surveillance needs.
  • When you cannot currently afford to spend the extra money on high-end 4K cameras but still want great image quality.

These systems are best used in entrances, walkways, and small campuses. 

4K Security Cameras

  • If you need to capture surveillance footage of the highest possible quality e.g in banks and jewelry stores.
  • When you have the budget for quality cameras and recorders with sufficient storage.
  • If you need to monitor large areas with a single camera. 
  • When you need a future-proof video surveillance system you can invest in. 

4K security cameras are perfect for small, medium, and large businesses including warehouses, parking lots, driveways, multi-tenant buildings, retail stores, hotels, restaurants, and large campuses.
