Security Camera Range: Factors to Consider 1

Having your security cameras in the right place is just as important as having them. If your cameras are in the wrong place, you may lose out on getting evidence of important events. When you are determining camera placement, you should think about how far they will be able to see. Placing them too far from the area of interest will prevent you from capturing clear footage, but you won’t be able to cover a lot of area if you place them too close. A typical home security camera can see within a range of 0-70 feet, but there are other factors that can affect this range. In this post, we will go over some things that affect security camera range so that you can figure out the optimal placement.

Factors That Affect Security Camera Range

Focal Length & Field of View

Focal length refers to the size of the security camera lens and this affects your camera’s field of view. Field of view and range are often confused with each other, but range is how far a camera can see while field of view is how much, or how wide, it can see. A smaller focal length will cause a wider field of view, but objects will appear smaller and more distant from the camera. So you’ll be able to capture more, but what is captured will be less detailed and fuzzy. A bigger focal length will cause a more narrow field of view, but objects will look bigger and closer to the camera.


A wider field of view does allow you to see more things, but it sacrifices image quality. That is why resolution is another deciding factor in the range of your security camera. Resolution refers to how many pixels make up your image. The higher the resolution, the more pixels that are in an image. More pixels means that your images will be more clear and detailed. A low resolution camera will produce images that appear blurry or pixelated. Having a higher resolution means that you’ll be able to see more details, even if the object is far away.

Location & Distance

This one seems obvious, but where you place your security cameras will affect their range. The further away you place your camera from the area of interest, the harder it will be to capture details. Additionally, you want to make sure that nothing is blocking the camera’s line of sight. If there’s any obstructions, like a tree or wall, the camera won’t really be monitoring anything of interest. But besides that, obstructions will make a wireless camera’s signal strength weaker and affect the image quality.


Another deciding factor in the range of your security camera is the quality. A camera’s specifications may be similar to another camera, but that does not mean that they are the same quality and will perform the same way. If you’re looking for security cameras that will give you the best performance, you should aim to purchase from reputable and reliable dealers.

  1. Oh, yes. Thanks a lot for making us aware of how many pixels does a security camera have before buying and setting it up. My husband’s workplace just got broken in last week and they’re tightening the alarm system at the moment. I’ll make sure they consider this aspect as well before making any further installation.
