| How to choose a wireless security camera Wireless
security cameras are cameras that do not require a connecting
cable to be run between the camera and the recording or viewing
device. They use a radio transmitter to transmit the video
signal from the camera to a receiver, which is located near
the recording or viewing device. The primary advantage of
wireless security cameras is their ease of installation. With
a traditional wired camera system, running the cables can
cost as much or more than the cost of the equipment itself.
In addition, wireless security cameras can be installed in
locations where it would be difficult, if not impossible to
run cabling.
There are a number of factors to consider
when choosing among the available models of wireless security
cameras offered by totalsecuritywarehouse.com. One of the
first things to consider is where the camera is to be mounted.
If the camera is to be mounted outdoors, then it is necessary
to choose a weatherproof model. Also, you need to consider
the temperature range where the camera will be located. Consider
a model with a built-in fan and heater if the outdoor temperature
in your area reaches extremes (less than -10 degrees F or
more than 104 degrees F for color cameras, -10 degrees F to
+122 degrees F for black and white cameras). Also, keep in
mind that each of the wireless security cameras will require
a plug-in for the power supply to the camera.
Another factor to consider when choosing
wireless security cameras is whether you need color or black
and white. Color cameras provide more detail, such as the
color of a car or the color of a person's clothing. But black
and white cameras actually provide more resolution and can
operate with less available lighting. For example, you might
be able to make out a license plate number captured at some
distance with a black and white camera, whereas with a color
camera you would not be able to read it at the same distance.
For the best of both worlds, consider choosing one of our
dual-mode wireless security cameras. These cameras operate
in color during the daytime, and switch to black and white
at night when there is less available light.
You also need to consider the distance between
the camera (transmitter) and receiver when choosing wireless
security cameras. All of our wireless security cameras use
a 2.4GHz transmitter/receiver combination, which can transmit
a clear signal up to 700 feet with a direct line-of-sight.
Line-of-sight means with no obstructions in the path between
transmitter and receiver. In a typical home or business application,
there should be enough extra signal power to transmit a few
hundred feet even through obstructions such as ceilings and
walls.
There are a few more factors you should consider
when choosing wireless security cameras, such as the type
of sensor the camera uses, low-light operation (LUX value)
and the resolution provided by the cameras. There are two
major types of sensors - CCD or CMOS. CCD sensors use analog
technology and typically operate at lower light levels and
with a higher resolution than CMOS sensors. However, CMOS
sensors use less power, which can be an important factor in
batttery-powered cameras.
The LUX value gives an indication of the
low-light sensitivity of the camera. The lower the LUX value,
the more sensitive the camera is to light. For example, a
camera that “sees” down to 1 LUX would be able
to record a usable image in the late afternoon, around dusk.
A LUX value of .1 would allow use of the camera in a well-lit
parking lot on a dark night. A LUX value of .05 would actually
be able to record an image in very dim light, better than
the ability of the human eye.
The resolution of wireless security cameras
is another factor to be considered. Resolution is usually
specified in the number of horizontal lines - this is the
number of lines that the camera "paints" on the
screen when viewing an image on a monitor. The higher the
resolution the better the picture. A typical "standard
resolution" would be around 320 lines for a color camera,
or 380 for a black and white model. A typical "high resolution"
would be 460 for a color camera or 560 for a black and white
model.
As you can see, choosing wireless security
cameras can be a complicated process. This is all the more
reason to do business with totalsecuritywarehouse.com, and
