Security Camera Picture Quality

Most security camera brands promote their systems as having exceptional image quality but we hear regular complaints about poor picture quality, especially with some of the DIY systems that are currently available.

Are security cameras really the quality they claim to be? Why would this be happening? In some cases the security cameras have not been set up correctly or positioned in the right place. Another cause can be the resolution of the monitor that the images are being viewed on or recorded to.

Image resolution and frames-per-second are functions that can have the most impact on image quality. Resolution is the amount of pixels that make up the image and frames-per-second relates to how many pictures the camera takes each second while recording. Usually, the more pixels there are, the better the image quality, but there can be other factors like monitor resolution and configuration. Most security cameras can shoot up to 30 fps (frames-per-second) but lower frame rates are sometimes more favourable because it keeps video storage consumption lower saving memory, space and bandwidth consumption.

Other considerations include the security camera’s field of view and camera positioning. The field of view is the area the camera can see at any given time and a wider field of view means the camera sees more. Camera positioning can also greatly affect picture quality because of the way they deal with light. If a camera is facing the sun or there’s a bright light close by, the image may be washed out and have less detail.

The most common resolutions for security cameras include:

  • 2MP (1080p) – Image size 1920 x 1080
  • 4MP (1440p) – Image size 2560 x 1440
  • 5MP (1920p) – Image size 2560 x 1920
  • 8MP (4K/2160p) – Image size 3840 x 2160

Choosing the best security cameras for your needs will depend on the camera location and the level of detail required in the viewable image. There is no one-camera-fits-all situation, so it’s best to consider your entire security set up, where you want to position the cameras (indoors / outdoors), lighting and image quality expectations as well as what type of monitor you are going to view the footage on before you make a purchase.
