Bullet cameras are great for home, office, day care, or any other commercial or industrial application.
Their small size makes them easy to mount or conceal. We carry an assortment of cameras with varying resolution, low light ability and lens sizes to fit most needs. These bullet cameras are also weatherproof making them ideal for both
indoor and outdoor applications.

Help for Choosing the Right Bullet Camera
Bullet cameras are very popular for their size and versatility. Things to
consider when buying a bullet camera are the resolution of the sensor, size of
lens (e.g. 6mm, 8mm) provided, whether it has a color image, black and white or
both and its weatherproof rating if used outdoors. Obviously the higher the
resolution of the camera the better the image quality but that should not be
your only consideration. The size of the lens must also be considered. It will
determine your field of view or viewing angle which can greatly affect the
overall image you see.
- Generally for nearby surveillance of 20 feet to 30 feet a 3.6mm to 4.3mm
lens is good. This will give you a wide view of the area and facial
recognition out to about 25 feet. This doesn't mean you can't see people or
objects much further away they'll just appear smaller and harder to see
clearly. If you need to see facial detail at a further distance of 35 to 50
feet away you would probably want to go with a 6mm or 8mm lens. However as you
increase the size of the lens, for example choosing a 6mm lens instead of the
3.6mm you will loose some field of view but gain greater detail of the object.
So you need to decide what it is you want to see and how far away you need to
see details clearly. Often times this means using two cameras instead of one
but the benefit is actually having clear evidence when something does happen.

Lens Field of View calculator for help on determining the size lens you
need.
- Adequate lighting can be an issue with these small cylinder cameras since
they do not have infrared illumination. In general if you have a very low
light situation a camera with a black and white image produces a better
picture. Lux rating is used in CCTV applications to classify how well a camera
sees in low light and the smaller the number the better. A camera with a
rating of 1 or .1 lux will need some light source at night to see well. With a
.05 lux or better rating the camera can produce a useable image in low light
but not so low that you would have a real problem reading a newspaper. There
are some color cameras that employ a sense-up technique that slows the shutter
speed and can produce images in much darker environments. One such bullet
camera is our
DNR230NHW
camera. Another camera that can see quite well in very low light is our
HL230EX however it is strictly a black and white image
- Not all cameras are equal when it comes to weatherproofing. The IP Code
(or International Protection Rating) is a rating of how well a device is
protected from the elements. Not all cameras state their IP rating but IP65 is
considered good for most outdoor weather conditions. If your camera will be
exposed to some severe weather conditions you should probably choose a camera
with an IP66 rating or higher.
