Bullet cameras are also called lipstick cameras and are commonly used for outdoor applications. Most bullet cameras are limited to a fixed focal length and are 2 to 2.5 inches long. They get their name because of their shape and size. Bullet cameras are good for small spaces due to their small size. Many of the bullet camera models are known for their infrared capabilities. Most distributors sell some form of these security camera systems when their customers are looking for a night vision camera. Some models are capable of transmitting images as far as 20 feet in complete darkness. These security camera systems are often the first line of defense in preventing and reporting nighttime intruders to your home or business. Another common feature is a sunshield that prevents glare when operating the camera on a sunny day.
