Modern listening devices can have an effective range of up to 1640 feet, though there is significant variation depending on the make, model and configuration. Let’s look at how we can use typical listening devices before delving into the range of options on offer.
Listening Devices Uses
Listening devices can be used for a variety of purposes. You can surveil unsuspecting people from a distance, listen through a wall, and even monitor your favourite wildlife. A little research indicates that the most common uses for listening devices is to bug a room, and also to catch a cheating spouse.
Using Listening Devices
Listening devices can be disguised as every day items and are therefore perfect for bugging rooms, when the unsuspecting person would never suspect. Common disguises for listening devices include : calculators, USB sticks and power adaptors.
The more complex and expensive listening devices contain a transmitter and reciever and allow you to monitor conversations from greater distances – as we’ve said, up to 500 feet. Using these devices, you’d need to hide the transmitter as they are not as well disguised. Typically you would place the transmitter between books, behind an ornament etc – anywhere where the transmitter can be hidden but the mic can still pick up sound without obstruction.
These type of listening devices can typically record for about 16 hours straight. Of course, they are sound activated in many cases, so you won’t need to just leave them on continuously and hope for the best.
Because of this, you can record conversations for days, weeks and possibly months at a time without needing to worry about the battery life. It all depends on how long the conversations last (very few people talk for 16 hours straight!).
Some of these listening devices allow you to acivate manually via cell phone rather than waiting for voice activation. This is perfect for when you want to listen in on a conversation that you know will take place at a specific place and time.
Most modern listening devices run on Wifi so you don’t need to worrry about cables and wires.
Legality Of Using Listening Devices
13 US states forbid covertly recording conversations, period. They are listed below:
US States Where It Is Illegal To Record Audio Without The Subjects Consent:
- New Hampshire
In every other state in the US it is OK to record audio as long as 1 person involved in the conversation gives permission. If you are using a spy camera with audio, you will obviously give permission since you are the person recording!
