This article helps provide an appreciation for these factors, common misunderstanding for buyers, and a comparison of camera performance. With an analysis using common types of cameras: optical surveillance may provide a range of 10-700 feet.

Surveillance Camera Range Visualizer
Here is a great tool by IPVM to help you see for yourself the range of a slew of surveillance cameras. This application helps you simulate different camera configurations and also gives you imaging quality during the day vs. night.
Field of View
Field of view or FOV describes the portion of the visible world that is displayed by a camera, based on capabilities of the camera and its lens.
Factors for width of FOV – In general the larger an image sensor and smaller a camera lens, all things held equal, provides for a wider field of view. The common sizes of lenses arranged in the order of wider field of view is 4mm, 8mm, and 12mm. See here for info by WECU Surveillance on the impact of FOV by camera lens.
Factors for distance of FOV – On the other hand, a larger lens provides a longer viewing range for your security camera. As mentioned in a post by Rugged CCTV the larger your lens, the greater the viewing distance provided.
Common Security Pitfalls
Silvas Consultants offers three points to inject a dose of reality into some underlying yet unspoken assumptions buyers may have. These common pitfalls serve as a strong warning for surveillance owners to get informed about the quality and range of their security cameras.
Security cameras rarely serve as a deterrent to crime – there is no firm evidence that argues concretely that security cameras can deter crime, though it often helps would-be perpetrators think twice before acting.
Most recorded footage is ineffective as evidence – surveillance owners are usually not aware of the limitations of their system, and it is usually too late. Often the result is, “I can see the person, but I can’t identify them”
“Megapixel” cameras are not silver bullets to surveillance issues– capabilities of megapixel cameras have been over hyped and a robust surveillance system cannot be boiled down to simply more pixels.

Quick Reference Camera Ranges
There are many factors that impact the visibility of objects and individuals for a camera. As a general rule of thumb, Gloria Sumter offers the following [annotations bracketed]:
- Most indoor and small outdoor cameras are good for about 10-30 feet
- Larger bullet cameras [perform well] for about 50~60 feet
- PTZ Cameras [perform well in the ranges of ] 200~250m or 500-700 feet
Gloria further provides a breakdown for viewing (FOV) a human on camera taking up 20% of the camera display vertically. Her analysis assumes the following factors for the various types of cameras described
Target Width: 10.70 metres – that is the viewing width of the camera is 10.70 metres
CCD: 1/2.8″ type sensors
Target Vertical: 8.02 metres – the view height of the camera
See definitions below.
Distance from Object a Key Factor
Distance from an object is a significant variable that often is neglected when choosing a security camera, which has impacts on the image lighting and quality of what is being monitored. As described by Security Today, the closer the camera to the target, the more light is collected, resulting in a sharper image. The prospect of bringing the camera closer is the simple solution. Yet this approach is often bottlenecked by a lack of wired internet connectivity and available power source. Security Today suggests that to help your camera go the distance, innovations in solar and wireless technology are helping to bridge those gaps.
