Your smart camera is the eyes and ears of your security system, but you lot need to put it in the all-time position to see what'due south happening. That's easier said than done, since you lot can't exactly predict where robberies will happen. There are, however, a number of things you can practise to maximize the possibility of capturing incidents.

One thing you tin can do is to put your camera in the right places in your dwelling house. The other affair is that you demand to learn how to use its field of view to best angle your camera. But what exactly is field of view, and how can you use it to your advantage? We've put together this guide to help yous figure it all out.

What is field of view?

Field of view is a adequately fancy term for something we all empathize. Essentially, the field of view is what the photographic camera can actually see. Everything a camera tin can capture is in its field of view.

It'due south not to exist mistaken with the term "angle of view." At that place are a number of disagreements about the ii terms. Some people believe they mean the same matter, while other people believe at that place'south a small-scale divergence. For our purposes, bending of view isn't also of import.

Y'all just need to know that the field of view is what your photographic camera tin can see. Field of view is often expressed as a numbered angle. For example, some cameras have a field of view of 130 degrees. Only what does that mean, and how does it work?

How does field of view piece of work?

It's all-time to think of the field of view as a cone of vision. The wider the field of view, the larger the vision cone is. This has a number of benefits and drawbacks in the world of cameras.

Cameras oft use lenses that residuum field of view and focal length, which is the distance the camera tin meet. The shorter the field of view, the longer the focal length. That means that if your camera has a smaller field of view, it should be able to run into things further away. You tin can meet this effect when you look through a telescope.

On the other hand, the wider the field of view, the shorter distance your camera is going to cover. The view that'south determined by the combination of field of view and focal length is chosen the viewing angle, and at that place are v chief types that are used by cameras.

Superwide-bending

Cameras with superwide-angle lenses have field of views of 180 degrees. They can encounter everything in forepart of the camera, which creates a fisheye consequence that distorts the epitome. You can see this in some peepholes.

This angle can be skilful for security, merely it oftentimes distorts the paradigm too much to be usable to identify burglars and robbers.

Wide Bending

Wide angle cameras often accept field of views between 60 and 110 degrees. More modernistic smart cameras tend to go beyond 110 degrees to provide a piffling more coverage. Cameras in this range are the best for smart security cameras, as they provide plenty altitude and width to cover an entire yard.

Standard/Medium

This is where traditional photography cameras come in. These cameras, like the one in your phone, are often congenital to capture the earth in slices. That'due south why they rest out the field of view and focal length to give you a good all-around experience.

Standard lens have far smaller field of views than the 135-caste field of view the human being centre uses, instead sitting between 25 and threescore degrees. Yet, it'll also allow you to encounter slightly farther than human vision.

Telephoto

This is where cameras start to cede field of view for focal length. The easiest way to recollect about telephoto is that it's the standard lens, but zoomed in 2X.

The image ofttimes has half the field of view of a standard lens, but it likewise is zoomed in twice as much. Many smartphones in the past couple of years have added a telephoto lens, allowing you to see the divergence in existent time with a quick button press.

Super Telephoto

Super telephoto lenses cutting down the field of view to between 1 and ten, increasing the focal length to between 160mm and 600mm. They are best used by nature photographers who are trying to become a bang-up look at something very far away, similar an animal. Unless you lot know what yous're looking for, super telephoto lenses aren't likewise helpful.

How do you position your camera for the best angle?

The all-time angle for security purposes is often broad angle. While wide angle often ways you won't go every bit much detail as a telephoto or super telephoto, y'all will be able to monitor a wider surface area of land while still getting some detail.

Plus, if your camera is in loftier resolution – either 1080 or 4K – you'll have plenty detail for yourself or law to identify potential suspects.

To capture these moments yous'll need to position your camera for the best bending. There are two things to keep in mind hither: height and room positioning.

Photographic camera Pinnacle

There are 2 heights you lot're going to desire to consider for your cameras. The first one is but above hip level. It's best for when you're putting your photographic camera on a tabular array or acting as a virtual peephole for your forepart door.

You'll be able to see most of everything, but if your room is besides small you may become some weird distortions. That's why this angle is best for wide, enclosed spaces, similar a living room or a front porch. On a front porch, it could even help you see your unabridged forepart 1000, driveway and street.

The second angle is upward high, pointed slightly downward. This bending works only as well indoors and outdoors. It'll allow you lot to encounter everything while too being relatively out of sight. In your domicile, this will allow you lot to put it in many rooms. Yous'll be able to encompass the exterior of your garage, your front thou and especially your dorsum yard if you choose to put it outside, too.

Room Positioning

The second thing y'all demand to consider is arguably more important than the first. If you put your camera in the wrong place, it won't matter what height you have. For instance, if you put your photographic camera up high in the centre of the wall, your footage may get distorted on the sides.

That'southward why the best identify to put a photographic camera, outside or inside, is in a corner. If you put your camera in the corner of a room, it'll exist able to cover the longest altitude in your room, which is often corner to corner. This will help take advantage of its broad angle lens.

Similarly, putting your camera on the edge of the back or front walls of your dwelling house, letting it have a corner view of your back or forepart yard is ideal. You'll see your one thousand as a diagonal, over again letting it encompass the maximum amount of space.

This too helps it avoid dead spots, which tin happen when you put a camera in the heart of a wall. This tin allow smart burglars to stick to walls and avert detection past the photographic camera.

Get an easy-to-install camera.

Every room, yard and habitation is dissimilar. That makes finding the best bending for your camera'south field of view a bit of a personal quest. Yous demand to put it upward and test information technology to see what exact acme and corner works all-time for your home.

One style to make that procedure just a little chip easier is to get a camera with a good field of view and easy installation.
