A security camera can come in many different styles including
dome,
bullet,
infrared and
c-mount. The security camera that will work best for your application will
depend on several factors such as whether you will use the security cameras
inside or out, during the day, nighttime, or both.
Bullet style security cameras are the most popular. They can be used inside or
out. These security cameras come in black and white or color and come with all
of the required mounting hardware. The security camera casings are weather
resistant and don't require added external protection. Most security cameras
have a fixed 4mm lens that allows you to see facial features out to about 35
feet and provides a 70 degree angle of view. This is the widest angle you can
have without distorting the picture. Click here for more information about

security cameras.
Resolution levels for black and white security cameras are about 400 lines, any
higher and the benefits are minimal. For color cameras, the higher the
resolution the better.
Infrared security cameras are also very popular as they allow an image to be
seen in little or no lighting conditions. Most infrared security cameras are
bullet style and can be used inside or out. The cameras have infrared lighting
installed around the outer edge of the lens which allows the security camera to
see in no light for up to 25 feet - even further with a little bit of light
(like street lighting or an outside light.) Click here for more information

A relatively new type of security camera to the market is the
day / night security camera. These types of security cameras have an extra
sensitive imaging chip which allows it to capture a good picture in low light
situations without using infrared leds. This is especially handy in outdoor
applications because infrared security cameras do not do well in outdoor
housings. Unless the infrared security camera is installed flush up to the glass
of the housing, the infrared lights can reflect off of the glass of the housing
which degrades the image.
The advantage to c-mount security cameras is that the lens can be changed.
You'll want a special camera lens if you need to see further than 35 ft. The
color c-mount security camera allows you to change lenses on the camera giving
you the ability to zoom into a particular area. Varifocal camera lenses allow
you to adjust the focus from 5 to 50 mm. These lenses can be used inside only
unless you put it in special housing for outdoor use. Click here for more

security cameras or

Dome security cameras basically provide a different look. Also, if you have any
concerns about tampering, check out our

blow and can be used inside or out, daytime or nighttime. Click here for more
