The Influence Factors
You might have many questions regarding the security camera and their performances. Here’s the list of factors that you should check before you finalize the security system for your home.
Factor 1: Field of View
The field of view of the CCTV camera depends upon the lens and the sensor of the camera. It describes what scene your camera is capturing. If you are a photographer, then you might be aware of this term. The wider field of view of the camera can cover more area of the field.
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.
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.
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.
Factor 4: Location
The location of your security camera can also affect the picture quality and the distance that the camera covers. You have to consider this factor while installing the camera outside your premises.
You need to understand the height of the camera, the angle of the camera, the direction of the sunlight, etc. If the sunlight goes straight to the camera’s lens, then it will not get you a clear picture.
Factor 5: Quality
The quality of the security camera is also an important factor while installing a new surveillance system on your premises. There are many types of security cameras present in the market, depending on your requirements, you can easily pick a suitable camera with a good lens and great build quality.
While installing the camera, you also need to take note of the obstructions such as trees, concrete floors, bricks, etc. Make sure that the camera you are installing doesn’t face any obstructions. This is how you can get the best of picture quality and performance from the camera.
If you are installing the security camera outside your premises, then you have to pick the cameras with great build quality. Security cameras come with a different set of features, you need to read about the list of their features first before you pick them.
Factor 6: Night Vision Capabilities
Almost all security cameras come with infrared illumination. Cameras with this feature support night vision that means they can record things during the dark. You can see things in the dark with this feature on the security camera.
If you want quality results from your camera during the dark, then you have to spend some extra money to buy a quality camera.
