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.
