6 Factors for Purchasing the Right Wireless Spy Camera
By Max Penn
Wireless spy cameras let you easily see whatever you
want to see and finally at an affordable price!
You can now get the evidence you want with sophisticated,
super small spy cameras. From cheating spouse to the
nanny and children, a spy cam can see it all.
How It Works
The camera captures what is in the field of view and
transmits the video footage over radio frequencies. The
video is then picked up by a receiver that can be hooked up
to a TV for viewing, or to a VCR for recording.
What To Look For
1- Color or black and white -- Color models are
better at distinguishing different items in the field of view
and are also a bit more expensive. Black and white models
usually produce slightly higher resolution images and are a
bit cheaper than their color counterparts.
2- Sensibility to low light -- Measured in LUX. The
lower the number the better the camera sees in low light
conditions. For a decent ability to see in low light, opt for a
unit with a lux of 0.05 . For pitch dark situations 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 private
investigators.
4- Is the receiver included? -- If the receiver is not
included, ask how much one would cost and do the math
and see if it fits your budget.
5- Transmission frequency used -- This is the
frequency the spy camera uses to transmit the video feed
to the receiver. You have the choice of 434mhz, 900mhz,
1.2ghz and 2.4ghz.
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.
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.
IN CONCLUSION
You now have the necessary knowledge to buy quality
wireless spy cameras on your own so please keep in mind
these critical points before making any buying decision.
It will make the difference between getting the evidence
you want and having a useless toy that is no fun to play
with!
