How to listen through walls using spy gadgets

If you have ever wanted to listen to what your neighbors or your children are saying behind closed doors, there are a variety of options available. Available on Amazon and many other sites, there are spy devices which give you the ability to listen through walls.

Most spy gadgets that allow you to listen through walls can listen through materials like bricks, wood or any other sound conducive material. The device picks up small sound signals and amplifies them so that you can hear conversations clearly.

You could even use a wine glass and press it to the wall. The cone shape of the wine glass is shaped to pull sound. On the other ear, place cotton wool to remove external noise.

The choices of listening devices are huge: You could use a spy listening device, or you could use a remote listening device or you could use a door eavesdropping device

How bosses spy on employees and what can you do about it?

In a connected world, it is easy to know what you are up to. Your office place can be monitored using hidden cameras, the computer that you use can be easily spied upon. And you would never know till you are confronted with proof that you have been found visiting 'x' or 'y' website. This is extremely convenient in these times of recession -- organizations can keep mountains of evidence against you and use it when they need to.
Your location can also be tracked easily using sophisticated services such as World Tracker (www.world-tracker.com). This service which just needs a single confirmatory text from your phone can reveal your location to your employers. Nowadays, when companies give employees phones, this software could be pre-installed.

Technology is truly rapidly advancing. For example, a company called eTelemetry can not only prevent illegal downloads but can also correlate your IP address, machine location and other location related data - to make it easier for your organization to track you down in case of any violation.

In some companies, organizations also monitor the number of times that you gain entry or leave your office. This is backed by surveillance cameras which provide video related evidence.

How can you protect yourself
First and foremost, do not do anything that you will be ashamed of later. If you really want to surf, use proxies or use 'private browsing' feature in browsers such as Firefox. Do not send personal or funny joke e-mails to your colleagues using your official e-mail - you never know how it can be used against you.

How spy devices looking like insects are being used for surveillance and spying

How many of you would believe me if I told you that houseflies, bees and beetles (insects that we ignore and see all around) are being used to spy. Some look so close to the actual insects that it will be difficult for you to spot the difference.

Many of these devices are being developed by countries such as US and Israel.

Here is a snapshot of what has already been done:

A team of researchers at the Johns Hopkins University in conjunction with the US Air Force Office of Scientific Research at Wright-Patterson Air Force Base in Arlington, Virginia, is helping develop what they are calling a micro aerial vehicle (MAV) that will undertake various espionage tasks. It is said that the new device has the capability to land precisely on human skin, use its super-micron sized needle to take DNA samples and fly off again at speed. All people feel is the pain of a mosquito bite without the burning sensation and the swelling of course. The hard-to-detect surveillance drone can also inject a micro radio frequency identification (RFID) tracking device right under skin, and can be used to inject toxins into enemies during wars.

Cyborg Beetle

Scientists at the University of California have implanted electrodes and a radio receiver on the back of a giant flower beetle. This beetle can be wirelessly controlled via electrical signals delivered via the electrodes command the insect to take off, turn left or right, or hover in midflight. The research is funded by the Defense Advanced Research Projects Agency (DARPA),

A team at Harvard University has successfully built a housefly-like robot with synthetic wings that buzz at 120 beats per second.

Japanese researchers have already developed a radio-controlled hawk-moth. The device has four-inch wingspans that resemble hawk moths.

Prof. Robert C. Michelson and his design team from the Georgia Tech Research Institute (GTRI), University of Cambridge (England) and ETS Labs are developing an ‘Entomopter’, a multimode (flying/crawling) insect-like robot. What is unique about the Entomopter is the fact that it is propelled by a pair of flapping wings driven by a Reciprocating Chemical Muscle (RCM) which is capable of generating autonomic wing beating from a chemical energy source without an ignition source, combustion, or atmospheric oxygen.


The Israel Aerospace Industries (IAI) has created a butterfly shaped drone that can hover in mid-flight, just as a helicopter and take pictures with its 0.15 gram camera and memory card
