A
security cameras
can come in many different styles including dome, bullet, infrared
and c-mount. The
security cameras
that will work best for your application will depend on several
factors such as whether you will use the
security camera
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 cameras
casings are weather resistant and do not 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.
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.)
A relatively new type of
security camera
to the market is the day / night
security cameras.
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.
Security Cameras
Dome
security cameras
provide a different look. Also, if you have any concerns about
tampering, It will withstand a 10 lb sledgehammer blow and can be
used inside or out, daytime or nighttime.
