Bullet Camera Overview

Pros & Cons of Using Bullet Security Cameras

The term "Bullet Camera" comes from its resemblance to a rifle bullet. Generally long and tapered like a cylinder, it looks like an oversized ammo cartridge.

Most bullet cameras come with a fixed 3.6 or 4mm lens that allows a 70 degree angle of view. This is the widest angle you can have without distorting the picture. A 4mm lens will allow you to see facial features out to about 35 feet. If infrared is included you can generally see 35 feet minimum with no external lighting, some can see up to 200 feet or more.

Most bullet cameras capture images in color which is best for daytime lighting. For nighttime viewing choosing an infrared camera. Infrared cameras will capture color images during the day and automatically switch to black and white infrared viewing when light levels are low. Resolution levels for black and white mode are usually about 400 TV lines, any higher resolution and the benefits are minimal. For color, the higher resolution the better the picture.

Used in closed circuit television applications, bullet cameras contain essentially the same electronic components as c-mount cameras but have been modified to fit in a weatherproof casing for outdoor use. You can see from the image that some models allow the housing to be removed for installation indoors. Mounting brackets are included with each item. They can be installed on the ceiling or the wall. Voltage is typically 12V DC. Power adaptors are included with every camera.
