To say cellphones are an epidemic would be an understatement. Everyone is either using, about to use, or has just finished using their cellphone for something. Every time they use it, there are signals that are sent through the air that, with the right equipment, may be yours for the taking – or at least yours for a peek before they continue on their way.
For several hundred dollars, you can purchase a cellular scanner device that will allow you to intercept cellphone transmissions. This requires that you are well positioned to actually intercept this cross traffic, and also does not guarantee that you will locate the transmission you desire. If you’re willing to up the ante to around $3000, you can get a souped-up version of this device that allows you to pre-program up to 20 cellphone numbers that will be recognized and intercepted automatically.
Advanced cellular interceptors can also provide the identity belonging to unknown cellphone numbers, hook up easily to recording devices, and be used as regular cellphone. Just in case you have just joined us, this method of audio surveillance, like most of the methods outlined here, is not legal. A final spy tactic involves a slightly different form of cellphone surveillance – one that actually turns the phone itself into a listening bug.
The Nokia 3310 Spy Phone is a popular example. You can leave the phone somewhere and then dial in to listen to the remote location (though admittedly it would seem a bit odd for anyone to leave their cellphone anywhere other than their purse or back pocket). You may even consider giving it as a gift to someone you’d like to keep tabs on. Sneaky.
