There are several aspects to consider when purchasing a wireless spy camera.
In this article I will try to highlight several important points for deliberation before you make that all important purchase.
Frequency - you need to consider the frequency range the wireless spy camera uses to broadcast the video signal to the receiver.
The most popular ranges include 434MHz, 900MHz, 1.
2GHz, 2.
4GHz and 5.
8GHz.
Probably the most popular frequency exists in the 2.
4GHz range, this range is license free in the United States and all across Europe up to a yield of 10mW.
Because of interference, I would advise against using cameras that transmit on 434mhz and 900mhz, 1.
2ghz and 2.
4ghz are definitely the better options (Please bare in mind that the 1.
2ghz frequency range is not license exempt in the UK and certain other parts of Europe).
Transmission range - often shown as a 'line of sight' figure, it is the measure of the maximum distance between the wireless spy camera and receiver where you are still likely to receive a reasonable signal.
Because this is a 'line of sight' estimation it is calculated without obstructions between the two.
If you intend to use a wireless camera you will most probably have to deal with the problems caused by interference and obstructions, so never accept the transmission range advertised.
In the real world the effective range will not be as high as you are likely to have obstructions and possibly other wireless signals in the vicinity to deal with.
Certain materials will significantly restrict the flow of wireless camera signals, such as, non-porous rock like granite, slate, and marble.
Anything metal will completely reflect the signal and certain 19th century building practices like Wattle and Daub walls do not lend themselves well to the transmission of wireless signals.
So check your path from camera to receiver and make sure it is not obstructed by a radio signal bouncing materials.
Whether to go for a camera head or prefabricated unit - you can purchase a wireless spy camera head that is very small and is designed to be hidden by the person how buys it.
However, you can purchase pre-camouflaged units that are often manufactured into everyday objects.
Eye glasses, cigarette packets, lamps, teddy bears, air fresheners, smoke detectors etc.
So depending on your application, you could purchase a pre-camouflaged unit and your all set to go.
You will still need a wireless receiver but pre-hiddden cameras can be an easy and convenient solution as they are very simple to install.
If you intend to use wireless spy cameras you should have some knowledge of the local law regarding the utilization of spy cameras, in many cases, if you want the recordings for legal evidence the footage may not be allowable for use in a court of law.
