…to the same scene but with a field of view of only 7 degrees:īest leave this one to the paparazzi. You’d have to hope burglars happened to walk through the very narrow field of view by sheer luck.Ĭompare this photo with a viewing angle of 110 degrees… Think wildlife photographer shooting a pride of lions on the savannah or the paparazzi trying to sneak a picture of a celebrity vacationing on a private island.īut at only 1 to 10 degrees in coverage, a would-be thief would literally have to stop on a marked spot far away and smile for it to be of any use in security. Super-TelephotoĪ super-telephoto FOV is used primarily by journalists and photographers that want stunning detail captured from a great distance. With a range between 10 and 25 degrees, the field of view on a telephoto camera is just too small, despite the fact that it captures subjects in much greater detail.Ī telephoto field of view is great for zooming in on a particular subject and capturing crisp details, but it’s nearly worthless for monitoring a room or outdoor space. TelephotoĪt this point, the usefulness for security purposes plummets. Notice how objects appear sharper and closer to the camera than in the 90-degree photo above, but some items like the garbage cans and cars in the foreground are no longer visible. The photo below shows a 60-degree field of view. As far as security goes, a standard angle can be quite effective in a small room or if you’re only interested in capturing a specific section of the overall scene. You’ll only capture one-third of the scene at most, but with much greater detail and clarity, as objects and people appear closer to the camera. It has a viewing angle of 25 to 60 degrees. The photo below shows a security camera with a viewing angle of 90 degrees.Īs the name implies, this is the field of view for most cameras. For example, a camera mounted high in the corner of a room will capture most, if not all, of the scene, but one mounted in the middle of a wall will have blind spots on both sides of it. It’s ideal for security cameras in that sense.īy experimenting with security camera placement, you can usually reduce or eliminate the blind spots created by the reduced field of view. With a range typically between 60 and 110 degrees (or more), a wide-angle FOV sacrifices some coverage for better detail. Just be aware that superwide-angles don’t usually capture enough detail to identify individuals. If you’re looking for coverage of a large area like your backyard or parking lot but aren’t overly concerned with the crispness of the image, you can stop here. They can be useful when you want to capture as much of the scene as possible, but it comes at the expense of some detail and clarity. A superwide-angle camera warps the image and creates a fisheye effect like you see when looking through a peephole. That may sound ideal for security purposes, but there’s a catch. Some of them can even see the entire 360 degrees around them. What’s the difference, and when would you want each one? Let’s look a little closer.Ī superwide-angle (aka ultra-wide) FOV captures the full 180 degrees in front of it. Security Camera Viewing AngleĬamera field of view breaks down into five major categories: But it’s vital that you pick the correct one for the job. Sometimes you’ll want a wide field of view, and sometimes you’ll want a narrow one. You’ll be able to recognize greater detail, but you’ll have even less of the scene on your screen. The camera “sees” part of the scene, but not the whole thing. To see that in action, grab your smartphone, open the camera, and point it at whatever is in front of you. The bigger the lens, the smaller the field of view, but the more detail you’ll be able to capture. It’s closely connected to the size of the lens. But what exactly is it?Ī security camera viewing angle is how much a camera can “see” of the 180 degrees in front of it. You’ve likely seen it listed in degrees as part of a camera’s specs. For example, take the camera field of view (FOV), also known as the viewing angle. Camera A might be perfect for a task that Camera B can’t or shouldn’t do. While they all basically function in the same manner, cameras can differ in important but often forgotten ways. A camera is a camera is a camera, right? Yes.
