Human life is increasingly modern, security surveillance systems are also becoming more and more popular. Accordingly, there are many types of cameras produced on the market depending on usage needs. To have the right choice for the business CCTV system, users need to have an understanding of the product. In this article, DNG Corp will focus on giving you details about what a bullet camera is, as well as how this device works.
What is a bullet camera?
Bullet camera, also known as a body camera or a cylindrical camera, is a type of surveillance camera with a long shape that looks like a rifle bullet. Because the camera is quite long and has a fixed focal length lens, they are often installed on walls or ceilings. This is a line of cameras that can be used flexibly both indoors and outdoors because of its good resistance to natural environmental impacts such as: dust, sun, rain, etc.
The convenience of the body camera is that because of its long cylindrical shape, the manufacturer can easily arrange the lenses inside the device. Therefore, the bullet camera provides the ability to observe activities extremely well from a long distance. At the same time, the infrared LED lights integrated on the product are also designed to operate further than other product lines, serving the need for night surveillance.
How Bullet Cameras Work
A bullet camera works by recording footage and transmitting it to a recording device such as a digital video recorder or network video recorder. The camera is equipped with a lens to capture images and a sensor to convert the captured images into digital signals. These signals are then transmitted to the recording device via a cable or wireless connection.
To help readers better understand how bullet cameras work, DNG Corp will compare the differences between bullet cameras and other camera lines according to the following criteria:
Observation range
Similar to a dome camera, a bullet camera has a camera view of about 70 to 100 degrees. Meanwhile, a PTZ camera will provide a wider field of view because it supports up to 360 degrees of horizontal rotation, 180 degrees of vertical rotation, and 90 degrees of tilt.
However, in reality, the camera’s monitoring range depends on many factors such as: sensor chip, type of lens used, product resolution,…

Camera size
Bullet cameras are the most visible type because they are long cylindrical in shape, with some products measuring up to 8 inches. This helps you limit people who intend to illegally enter your business area, because when they see a surveillance camera, they will be more cautious.
Dome cameras are more difficult to determine the direction of observation, so they are the best choice if you want to hide.
Night vision
Most current camera lines are equipped with infrared LEDs for night observation. Typically, cylindrical cameras will have a night vision range of about 30m. PTZ cameras have a superior range of up to 70m.
Camera installation
Bullet cameras are designed for users to install easily and quickly. They often include a handle and bracket, so you only need to mount them on the wall in the area to be observed. Meanwhile, installing a dome camera is more complicated.
Advantages and disadvantages of bullet cameras
Here are some advantages and disadvantages of bullet cameras that people need to pay attention to in order to use the product most effectively.
Advantages of bullet cameras:
- The design of the camera is designed to be easily noticeable. Install the device right at the entrance as a warning to those with bad intentions or intending to break in illegally.
- The product has a good operating range. Because of its long cylindrical structure, you can easily change the lens size and focal length according to your needs. Therefore, they are suitable for large areas such as large offices or factories.
- Simple and easy installation. Bullet cameras often come with a base, so you just need to install them on the wall and adjust the camera’s angle as desired.
- Cylindrical cameras have a waterproof and dustproof standard of IP66 or higher, providing good environmental resistance.
- The images that the body camera records and transmits to the user are sharp and high resolution.
Disadvantages of bullet cameras:
- Because of the easily recognizable wall-mounted design, body cameras are not a good choice for places that require a secret camera.
- Compared to PTZ cameras, the viewing angle of bullet cameras is not as wide. In addition, they do not have an automatic rotation feature.
Should I choose a bullet camera or a dome camera
Before deciding which type of camera to choose for your business security system, you should grasp the basic information of each product line. Each type of product is designed and manufactured to perform separate functions.
Therefore, choosing a bullet camera or a dome camera will depend on the user’s individual needs. If you prioritize long-range observation and a simple device installation process, a bullet camera will be the choice for you. On the other hand, if you need hidden surveillance and a comprehensive view, a dome camera will be more suitable.
