Bullet 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 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 70 feet.

Some devices capture images in color which is best for daytime lighting. For night
viewing choosing an infrared camera, which captures images in black and white is
better. Many of the products will display color during the day and automatically switch to
black and white infrared viewing when light levels are low. Resolution levels for black
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 12V
DC. Power adaptors are included with every camera.
