There are plenty of options available when it comes to security cameras. In general, the higher the resolution, the better the image quality, and therefore, the more details you will obtain. However, not every situation requires the highest resolution camera. Read on for a comparison of the surveillance cameras currently on the market. 

Security Camera Resolutions

4k Cameras 

4k (3840p x 2160p or 8-million pixels) is currently the highest resolution available. These surveillance cameras are becoming more and more common. They are ideal for monitoring large areas with a single camera. However, they require more storage and use more bandwidth. They are also more expensive, but one camera does cover a significantly larger area. 

1440p Cameras

1440p (2560p x 1440p) surveillance cameras still produce extremely high-quality images. They have a comparatively wide field of view and show vivid details.

1080p Cameras

1080p (1920p x 1080p) security cameras are great for general-purpose surveillance. If you need a battery-powered camera, 1080p is the highest resolution currently available. 

720p Cameras

720p (1280p x 720p) surveillance cameras are for those on a tight budget. Due to better available options currently being priced down, 720p security cameras are slowly losing their grip in the market. However, they are still better than no surveillance. 

Other Factors

Image Quality

The higher the resolution, the better the image quality and more vivid the details. Therefore, 4k>1440p>1080p>720P. 

Field of View

Megapixel security cameras generally have a wide-angle lens. If you need to monitor a large area, one 4k surveillance camera does the job of approximately four 720p surveillance cameras. 


With a 4k security camera, you’ll need a 4k monitor or television. If you don’t have either, you’ll need to lower the image resolution, which defeats the purpose of investing in a 4k camera. 

Ideal Uses

  • 4k: Businesses, multi-tenant buildings, parking lots, long driveways
  • 1440p: Home entrances, small businesses, driveways, garages
  • 1080p: RVs, boats, construction sites, barns (any area needing a battery-powered camera)
  • 720p: Any area, if you’re on a tight budget
