Factor 1: Field of View

However, with a wider field of view, you may not be able to see accurate pictures of the objects since the objects will be much smaller as they are far away from the main camera. 

The focal length of the camera is the primary feature to consider while buying a security camera. Some cameras support external control that allows users to change the field of view with manual settings. 

What is Focal Length? 

The focal length of the camera determines how far the security camera can see. The focal length of the security camera can be fixed or variable, it depends upon the requirements of the users. 

Focal Length helps you to cover the area or we can say the field of view of the camera. The smaller focal length of the camera can cover a wider area of the field. A larger focal length can cover a narrower area of the field.

What is Focal Length?


If you are setting up the camera at a specific height, then you have to go with the larger focal length to cover the distance. However, in this case, you will have to compromise with the field of view i.e. the narrower area. 

Factor 2: Camera Resolution 

The camera resolution means the quality of images. If you want detailed images, then you have to pick the camera with at least 720 pixels of resolution i.e. the high definition resolution. To get the best results, we recommend you to go with the full HD resolution i.e. 1080 pixels.


Camera Resolution


If you are wondering about the right resolution for your surveillance system, then we would recommend you to study your requirements first. For getting a closer look at the object, a higher resolution camera is crucial. 

We have a range of Security Cameras with 4K UHD resolution. The 4K UHD camera offers great picture quality with clear audio. The resolution of the camera also depends upon the type of lens used in the security camera i.e. Telephoto or Wide Angle. 

Factor 3: Distance

If the object and the camera are far away from each other, then it will be a little difficult for you to see the object. You can’t get a closer look or a clear picture of the object when it is far away from the camera. 

Even if your security camera’s resolution is 4K, you may not get a clear picture as the object is far away from the main camera.
