Find out what is the angle of view on the camera?

With the continuous improvement on today’s surveillance camera devices, it helps to bring the ability to record with a wider viewing angle, making many users wonder what is the viewing angle on the camera? What are the benefits of a wider viewing angle? Now let’s clarify these issues in the article below to see how useful it is!

What is the viewing angle on the camera?

The viewing angle (viewing angle) of the camera is considered the width, the opening of the field of view that the camera can obtain , with the device having a wider viewing angle to bring a full image, helping us to see the space a little. way more coverage than the narrow angle camera.

Factors affecting camera viewing angle

Focal distance

Focal length is one of the basic parameters of a CCTV camera that has a great influence on how to choose a camera installation position, which is considered the distance from the optical center to the focal point of the lens to form the sharpest image of the object. with the common unit of measurement is millimeters .

With a camera with a smaller focal length, it means that the device has a wider viewing angle , providing the ability to capture a wide and complete image to help users observe many objects in the same frame compared to a narrow-angle camera. . Should be used for cases where large visibility is required such as monitoring warehouses, parking lots, etc.

This type of camera should be used for cases such as indoor surveillance, personal property, … in order to identify the bad guys breaking into the clearest.

Barriers

Obstacles or objects obstructing the range are considered factors that directly affect the range that the surveillance camera can receive, giving rise to a blind spot that makes the recorded image not fully displayed.

However, this problem can be completely reviewed and overcome by users by checking whether there is an obstacle in front of the lens to promptly fix it.
