Works well if you know what you're doing

With some astonishment I observe the partly bad reviews of this "Wireless RF Detector". This means namely "Wireless RF Detector" (RF = radio frequency = RF). And that detects the device. Not more or less. Radio bugs per se can not be distinguished from other legal radio sources with the same signal strength of course, most Funkdauerton or keyed tone can give some indication. Will say: Wireless Audio Bug Detector give in rather Signaldauerton, mobile phones, however intermittent beeps.

The instrument has no selection agent, it "listens" at the same time almost all RF transmissions. From perhaps 5 MHz to several 10 GHz. This is a huge frequency range. And on one of these frequencies somewhere an RF signal is emitted and the signal strength is sufficient enough, the device will sound the alarm. But those frequencies are in your room at this very moment hundreds available, but certainly with very different signal strengths.

And this is apparently the mistake of many users. Constantly is in apartments, houses, streets, towns, landscapes a variety of HF in the "ether". Some bulbs, fax machines, TV sets, etc. radiate indirectly from HF, indicating the unit just may. This is not an error, because the occupation of the device it is display HF. All these devices have "transmitting power", which are mostly lower than the bedbugs, a guarantee does not exist but.

The user must be clear what he wants to find and need to know that any electronic HF generated as a byproduct. So I hold the device close to a dimmer lamp, he is sounding the alarm, although no bug was installed. There are even radios that bring the device to display certain circumstances, because in radio and mixing stage oscillators are built, which could lead to the display.

How do you deal with the RF Detector? Switching, antenna can still be drawn in, turn up knob so far that the beep is just gone. Pull out antenna Now, it beeps now, is HF nearby. But that in no way proves the existence of a bug. It may be a technical electronic device at your desk, be the phone on the table, the laptop with its Wi-Fi, the wireless fixed telephone, etc. Even a strong Mobile phone transmitter on the roof could be a cause or an FM radio station 200 meters away.

How do I get more? I'm trying to be tested from the room to remove all these electronics or actually unplug it. Then I set the knob so that he is no signal at four locations in the room. Now I go from the room and look in detail if and where there is a signal. Always close to approach suspicious objects. May include a normal electronic part of this found that broadcast "must"? If not, would perhaps a candidate for a bug or maybe not.

Can the device beeps when I touch the antenna? Yes, otherwise it would not be okay. We humans are also antennas, which you can check times with a transistor radio: the reception is usually better immediately.

Can display the unit when I hold it to a wall? Yes, because there may be a power cable or a cable television cable, which may also act as an antenna and RF einschleppt.

You may wear a vase of flowers, a book, a cigarette lighter, the unit etc bring to display? No! I would check.

About what distance the RF Detector can detect bugs? In most cases only to very short distance (5 cm - 50 cm), as one pulls the antenna of the Detector and sets out fully the knob on sensitive, it indicates anything and you will find nothing.

How do I test the device on basic function? Take your phone, switch it off. Set next to the RF Detector directly, turn the knob so that just has no sound audible. Turn on the phone. After a short time the unit will "chirp" to start and to stop again when you turn off the phone. Repeat the test with the fixed wireless phone and the wireless router.

So you have now had experience with broadcasting services that also could possibly muster a bug. Never set the knob so that the unit will beep continuously.

Also note that bugs like to hide in electronic devices. If such a device around radiates something, it may be legal electronic radiation or indeed to bugs radiation. What are we doing there. Take the suspicious device from the mains. Beam is still relatively strong? There you go, bug found. But: There are also bugs that take their power from the "host instrument ...

Taking into what was said above is to use the device well and fulfills its task or at least helps in finding bugs.

But why do I take the deserved 5 stars only 4 stars? Because I feel inadequate, the English Mini-Guide.
