Hikvision Surveillance Camera Millimeters72

Hikvision is a leading provider of surveillance cameras and other security equipment. The company offers a wide range of cameras, including bullet, dome, and turret models. Each type of camera has its own advantages and disadvantages, so it is important to choose the right one for your specific needs.

One of the most important factors to consider when choosing a surveillance camera is the lens size. The lens size is measured in millimeters (mm), and it determines the field of view of the camera. A larger lens size will give you a wider field of view, while a smaller lens size will give you a narrower field of view.

The following table shows the field of view for different lens sizes:| Lens Size (mm) | Field of View (°) |
|---|---|
| 2.8 | 110 |
| 4 | 80 |
| 6 | 50 |
| 8 | 35 |
| 12 | 25 |

As you can see, a larger lens size will give you a wider field of view, but it will also reduce the image quality. This is because a larger lens has to collect more light, which can lead to noise and distortion.

If you need a camera with a wide field of view, then you should choose a model with a larger lens size. However, if you need a camera with a high image quality, then you should choose a model with a smaller lens size.

In addition to the lens size, you should also consider the following factors when choosing a surveillance camera:* Resolution: The resolution of a camera is measured in pixels. A higher resolution camera will produce sharper images.
* Frame rate: The frame rate of a camera is measured in frames per second (fps). A higher frame rate will produce smoother video.
* Night vision: Night vision cameras can capture images in low-light conditions.
* Waterproof: Waterproof cameras can be used outdoors in all weather conditions.
* Audio: Audio cameras can record sound.

Hikvision offers a wide range of surveillance cameras to meet the needs of any application. By considering the factors discussed above, you can choose the right camera for your specific needs.
