Detection

And just what do you need today to know if you or your apartment are being bugged?

The following products give an idea of what it takes to clean your place and how much these items of equipment cost

Today’s hidden-microphone cameras are wireless, so the latest machines scan the broadcast spectrum to see whether any are transmitting.

If there is a bug, it can often pluck the video or audio signal out of the airwaves.

The government originally used this technology on its Lockheed P-3 Orion surveillance aircraft.

Sometimes the analyzer makes an accidental find, like the nefarious voyeuristic videostream that was apparently originating from a cam concealed in the bedroom of a client’s neighbor. $109,000
.
Next is the Inova Ultraviolet Flashlight - the one shown above
.
Fresh paint absorbs UV light; old paint reflects it.
.
A UV flashlight is a low tech (and low-cost) method of examining walls, woodwork, and molding for touch-ups that might hide newly embedded devices.
.
If the paint doesn’t glow, you may have a bug infestation. $50
.
Then there is the Merlin-MID Thermal Imaging Camera
.
A sensitive infrared camera detects minute variations in temperature.
.
Slightly warm areas can indicate heat emanating from a surveillance gadget.
.
A device buried inside a table or behind a wall will be difficult to detect otherwise, but its heat will bleed out.
.
Has the teleconferencing system in a meeting room been turned on surreptitiously to eavesdrop on conversations?
.
If its components glow on the camera’s screen, then you’ve got your answer. $56,000
.
A REI Multifunction Digital Telephone Analyzer
.
This gizmo is like a Swiss Army knife for spy busters, with sensors that detect voltage, current, resistance, capacitance, nonlinear junctions, digital demodulations, frequency domain … the whole ball of wax.
.
It can spot when a digital phone system is leaking audio
.
Identify when someone has done a bit of rewiring
.
Sniff out devices that are transmitting
.
And even tell whether a phone has been altered to continue capturing sound after it’s hung up. $20,000
.
Then we have the AirPatrol Digital Surveillance Location Analyzer
.
This location analyzer defends against two new surveillance threats:
.
One is a cellular eavesdropping device that silently begins picking up sound when it’s called.
.
The other is the GPS tracker, which can be concealed inside a vehicle to monitor movement.
.
To uncover either, set up a series of receivers around the area being inspected, all of them connected to the location analyzer.
.
The system pinpoints hidden devices by calculating the time it takes for signals to reach each receiver. $21,000
.
Finally we have a Nonlinear Junction Detector
.
When bugs are turned off and not transmitting, devices like the Tektronix Radio Spectrum Analyzer are useless.
.
That’s when this apparatus comes into play.
.
Like bicycle reflectors shining red in your headlights, the components of surveillance devices—semiconductors, transistors, diodes—bounce back radio signals at a particular frequency, which the junction detector “hears."
.
It works on the same basis as detectors of shoplifting tags. $20,000

And when you have used all of these you can have a nice warm feeling that nobody is spying on you............... until you go out that is because then you would need to check all over again

Unless of course you leave certain other devices around to inform you of any intrusions.

How pleasant not to care one way or the other!
