2K vs 4K security cameras

When it comes to buying security cameras, you’ve probably wondered what to choose between full HD 1080p security cameras, super HD 1440p (2K) security cameras, or even more advanced ultra HD 4K security cameras. Security camera resolutions are getting better every year. Although the standard for security cameras has been 1080p resolution, more companies in the surveillance industry are offering 2K and 4K video resolutions.

But the question is, are 4K security cameras worth it, or should you just stick to 2K cameras? Take a look at the differences between a 2K vs 4K security camera for more on how to make the best choice.

2K Super HD Security Cameras

A 2K camera provides a video resolution of 2560x1440 with a 4 megapixel (MP) image sensor. These cameras are mainstream in today’s competitive security camera industry and deliver much clearer and sharper images and better quality videos than 1080p and 720p security cameras. The images they produce give a much clearer picture to catch details like faces and license plates from a distance. These cameras also typically come with a wider field of view than 1080p cameras.

When to Choose a 2K Security Camera vs 4K Security Camera

  • You want to enjoy high-quality images with clear details from a distance
  • When 1440p resolution is enough for your home or video surveillance needs
  • When you don’t want to spend money on high-end 4K cameras but still want great image quality

2K security cameras are great for monitoring entrances to your home, garages, walkways, backyards, front yards, and small businesses.

4K Super HD Security Cameras

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 compared to 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.

To further understand 2K vs 4K security camera options, understand that 4K cameras provide more vivid details than 1440p cameras and are great for recognizing faces and identifying license plates even at a greater distance. They also have a greater field of view than 2K cameras, meaning that a single 4K security camera can monitor a huge area.

Although 4K security cameras are great, they require more bandwidth, and storing their footage requires more space than with 2K camera systems. The good news is, newer video compression technology is making it possible to further reduce storage consumption. Look for cameras that feature H.265 video encoding. This codec can save space by up to 50% over older H.264 encoding.

When to Choose a 4K Security Camera vs 2K Security Camera

Business surveillance

  • You must capture surveillance footage of the highest possible quality
  • You have the budget for quality cameras and recorders with sufficient storage
  • You want to monitor large areas with a single camera
  • You want to upgrade to 4K resolution systems
  • You need a future-proof video surveillance system

Are 4K security cameras worth it? In short, yes. These security cameras are perhaps the best surveillance option you have when you want the best resolution for monitoring small, medium, and large businesses including warehouses, parking lots, driveways, multi-tenant buildings, retail stores, hotels, restaurants, and other large residential and commercial properties.
