| How To Buy A Wireless Spy Camera

|
1) There are Color or black and white spy cameras.
Color wireless spy
cameras are better at distinguishing different items in the field of view but
may be a little bit more expensive. Black and white models usually produce
slightly higher resolution images and are a little bit cheaper cheaper than
their color types.
2) Sensibility to low light.
Measured in LUX. The
lower the number the better the camera sees in low light conditions. For a spy
camera to see in low light, go with a unit with a lux of 0.05 . For pitch dark
covert operations opt for a lux of 0.03 .
3) Image quality.
Measured
in lines of resolution. The higher the number, the better the image quality. 380
lines of resolution is usually good enough even for professional private
investigators.
4) Is the Receiver included?
The receiver is what you
connect to your TV, VCD or DVD to view the images and sound from the wireless
spy camera. If the receiver is not included as part of the camera cost, ask how
much one would cost and see if it fits your budget if it is an extra change.
5) Transmission frequency used.
This is the frequency the wireless
spy camera uses to transmit the video signal to the receiver. There are
currently 434mhz, 900mhz, 1.2ghz and 2.4ghz transmission frequencies. Most good
spy cameras are 2.4ghz and is sufficient for all covert surveillance operations.
Because of interference, you should stay away from 434mhz and 900mhz
models. 1.2ghz and 2.4ghz are the better options.
6) Transmission range
Measured in 'line of sight', it is a measure of the maximum distance the spy
cam can stand away from the receiver and still receive the signal with no
obstruction and interference between the two. The range is usually between 300
feet and 2000 feet depending on the model. Many wireless spy cameras specify a
line-of-site range and the range if there were wall obstacles present.
7) Hidden Camera or Stand Alone
There are Wireless Spy Cameras that
can be mini and wireless that you can attach to a pole, hide in a box or flower
pot and there are mini wireless cameras that are what they call Hidden Wireless
Spy Camera. These cameras are placed into ordinary looking every day objects
that we see in our environment every day, like smoke detectors, lamps, teddy
bears, air fresheners, mirrors and many other objects. So depending on your
application, you may want to get a hidden wireless spy camera and you are all
set. You still use a receiver like the stand alone spy cameras but hidden
cameras are more convenient and easier to place in your home or business.
WARNING: This figure can be misleading. Interference and obstruction are
things you will probably be dealing with to some degree, so never accept the
transmission range advertised as the real world effective range. Ask the store
for a more realistic figure.
So now, you now have the necessary
knowledge to buy a quality wireless spy camera on your own for any number of
secret covert operations so please keep in mind these 7 basic factors when
choosing one.
