Wireless spy cameras have numerous uses of which, detecting employee theft, capturing mistreating care givers, unfaithful spouses, overcurious landlords and thieving roommates are just a few.

1) Wireless spy cameras can be black and white or color.

You will get better object definition from a colour wireless spy camera but are often a little bit more pricey. Black and white models usually produce somewhat higher resolution images and are a little bit cheaper than their color counterparts.

2) Low light sensitivity

LUX is how the light sensitivity of a camera is measured. The lower the number the better the camera sees in low light conditions. For a spy camera to see in poor light conditions, go with a unit with a LUX of 0.05. 0.03LUX will give you near pitch dark covert spy camera operation.

3) Image Picture quality.

Measure. The greater the number of TV-lines your camera produces, the better the image quality will be. 380 lines of resolution is usually good enough even for professional private detectives.

4) Does the receiver come as part of the bundle?

You plug your receiver into your TV, VCR, PC or Digital Video Recorder (DVR), in order to view / capture the images and sound from the wireless spy camera. If the receiver is not included as part of the camera cost, find out how much extra the addition of a receiver will cost.

5) The radio frequency the camera transmits on.

This is the frequency range the wireless spy camera uses to transmit the video signal to the receiver. There are currently 434MHz, 900MHz, 1.2GHz, 2.4GHz and 5.8GHz transmission frequencies ranges. Probably the most popular frequency exists in the 2.4GHz range, this range is license exempt in the USA and all across Europe up to a yeild of 10mW.

Because of interference, you should avoid the use of 434mhz and 900mhz units. 1.2ghz and 2.4ghz are better options.

6) Transmission range

Measured in ‘line of sight’, it is a measure of the maximum distance between the spy camera and receiver and still receive the signal with no obstacles and interference between the two. This distance can be anything from 50 metres to 200 metres and is dependant on the model.

7) Disguised or hidden camera

Usuallywireless spy cameras are minute and are designed that way to be very simple to obscure by the operator, however, it's also possible to acquire pre-concealed units that will come made into an everyday items. Eye glasses, cigarette packets, lamps, teddy bears, air fresheners, mirrors, Smoke detectors etc. So depending on your application, you could purchase are pre-concealed unit and your all set to go. You still use a receiver like the stand alone spy cameras but pre-disguised cameras are more convenient and easier to place and install in your home or business.

Please be aware: If you intend to work with small wireless camera you will most probably have to deal with the problems caused by obstructions and interference, so never accept the transmission range publicized as in the real world the working range will not go as far. Before buying always ask for more realistic transmission ranges .

So with your recently learned wisdom needed to buy a good wireless spy camera, remember to keep in mind these 7 basic components for choosing one. It could make the difference between getting the evidence you need or not!
