Make sure these listening bugs don't "drain" the power of the batteries too quickly.
Make sure it has good transmission range because the real world effective range can be shorter depending on environmental factors such as interference from other devices in the area.
For the safest, most covert and successful audio surveillance operations, i suggest you opt for wireless audio transmitters disguised as common household objects such as a calculator or an outlet adapter.
Listening Bugs of Choice
Calculator Spy Listening device
Unsuspicious device.
Cristal clear audio.
Can transmit to a distance greater than 250 meters.
8 days of continuous spying using a battery.
Outlet adapter Spy listening device
Extremely covert.
Cristal clear audio
Transmission range is 300 meters.
NO batteries needed. Will run FOREVER(The adapter take it's power from the wall socket!)
My personal choice is this outlet adapter because it can go on forever and never run out of power. And when you come pick it up, who cares if you are caught with an ac adapter in your hands.
so covert...
