Installing
a simple two or four camera home security system around your house will
make thieves and burglars think twice before coming near your property.
Today’s security camera system equipment is smaller, less expensive,
more sophisticated, and is packed full of features. This is great for
you as the consumer as you have more high quality options at your
fingertips than ever before! However, there are a ton of options and it
can be very confusing telling the difference between two particular
products if this is your first time dealing with the security industry.
General Information
This section will help you understand basic camera specifications and
their effect on the performance of the camera.
Analog camera resolution or picture quality is measured by the number of
horizontal lines the sensor chip in the camera provides and is called
"TV lines of resolution" or TVL. Naturally, the higher the TVL the
better the quality of the image.
• Standard Image Quality: 380TVL - 420TVL
• High Image Quality: 480TVL - 520 TVL
• Very high Image Quality: 540TVL - 700TVL
Infrared LEDs allow security cameras to see in dark areas by flooding
the area with infrared light. This light reflects off surfaces in the
area and is picked up by the camera's sensor chip which allows the
camera to see as if the area was lit by visible light.
• Number of LEDs: The more LEDs, the better a camera can see in low
light environments.
• Illumination Rage: Refers to the maximum distance at which an object
is visible at night.
Vandal resistance is in reference to whether or not a camera is
reinforced with a hardened plastic or metal housing so that it is more
ruggedly built. If a thief or burglar wants to get on your property bad
enough, they will try to damage or break your cameras so they are not
seen.
Indoor VS Outdoor Cameras
CCTV Cameras use electrical components that are sensitive to the
elements. If water or dust gets inside of your camera, the quality of
your video feeds will suffer and your camera may even stop working.
Weather proof housings help keep moisture and dust where it belongs, on
the outside.
If you are installing a camera outside and it is not in a weatherproof
camera housing, you will definitely want to double check the camera
specs to make sure that it is weather resistance rated.
There are many different levels of weather resistance that range from
minimal protection all the way to airtight, waterproof enclosures and
all of our outdoor cameras are fully weather resistant.
Color VS Black & White Security Cameras
Color cameras are the preferred choice for most security systems.
However, black and white cameras are slightly cheaper, more sensitive to
light, and can see better in darkness.
Infrared (IR) security cameras switch to black and white mode during low
light conditions to improve their night vision and return to color in
good light conditions.
IR cameras have gained popularity because of their flexibility and
become the standard type of camera installed in systems today.
