Hikvision Security Camera Lenses Focal Length Guide117

When choosing a security camera for your home or business, one of the most important factors to consider is the focal length of the lens. The focal length determines the field of view of the camera, which is the area that the camera can see. A shorter focal length lens will give you a wider field of view, while a longer focal length lens will give you a narrower field of view.

There are a few things to keep in mind when choosing the right focal length for your security camera.1. The size of the area you need to cover. If you need to cover a large area, you will need a camera with a wide field of view. A shorter focal length lens will give you a wider field of view than a longer focal length lens.
2. The distance between the camera and the area you need to cover. If the camera is going to be mounted close to the area you need to cover, you can use a shorter focal length lens. If the camera is going to be mounted further away, you will need a longer focal length lens.
3. The resolution of the camera. The higher the resolution of the camera, the more detail you will be able to see in the image. A higher resolution camera will require a longer focal length lens than a lower resolution camera.

Here is a general guide to the different focal lengths and their uses:
2.8mm - 3.6mm: These lenses are suitable for wide-angle surveillance, such as covering a large room or outdoor area.
4mm - 6mm: These lenses are suitable for medium-range surveillance, such as covering a driveway or backyard.
8mm - 12mm: These lenses are suitable for long-range surveillance, such as covering a parking lot or street.

Of course, the best way to choose the right focal length for your security camera is to consult with a professional installer.
