What Is a Bullet Camera?

Bullet cameras are a small, cylindrical type of video camera commonly used for surveillance purposes. They are very versatile and are available in resolutions just as high as other cameras despite their miniature size.

Bullet cameras are commonly used for surveillance.

Imaging

Due to their small size, bullet cameras function by using an inline video imaging chip rather than the standard board design.

Specifications

Bullet cameras are usually between 2 and 2.5 inches long and have a fixed focal lens because of the size limitations.

Names

Bullet cameras are also sometimes called "lipstick cameras" because of their shape or "inline CCD cameras" because of the chips they use.

Advantages

The bullet camera's small size allows it to fit into small spaces. Its size also makes it difficult to see, which is useful when used for surveillance.

Disadvantages

The drawback to the fixed focal lens in bullet cameras is that it limits their range. Another problem is that images are sometimes cut off if the camera's design conflicts with the lens or filter.
