9 best bluetooth gsms

Product description

The DD1206 is a new class of a counter surveillance device. Unlike typical sweeping type devices it can detect modern 'hidden' bugs which use such protocols as Bluetooth and Wi-Fi. Such bugs, especially Bluetooth types, are practically undetectable by common RF detectors due to their very low transmitted power and a special type of modulation. The DD1206 uses a separate channel (2.44GHz) frequency pre-selector to detect and locate Bluetooth and Wi-Fi with a much higher sensitivity. The unit then processes the demodulated signal in order to identify which protocol has been detected.In addition the unit can detect all types of 'conventional' bugging devices (FM-modulated transmitters, digital transmitters, GSM-bugs, etc.) The perfect tool for searching for digital and analogue transmitters in the frequency ranges: -Main antenna 40MHz – 4Ghz -Auxiliary antenna 2.44 Ghz -Increased sensitivity to Bluetooth/Wi-Fi signals allows the operator to detect wireless sources at distance of 50 cm- 2 m - Detects GSM, Bluetooth, Wi-Fi and RF -16-segment bar graph indicator providing a wide dynamic range -4 work modes: silent, sound, vibration and mixed -Correlation function discovers FM-transmitters by the presence of sound is different than other detectors this unit can produce a loop-back effect A microphone transmitter will pick up the sound and transmit the beep. The demodulation display will pick up the transmission and flash simultaneously. Also, when the unit detects other transmission different sounds will come from the unit depending the type of transmission it detects -2 levels of sensitivity (attenuator) -Durable metallic body -Microprocessor controlled - Includes the extra antenna allowing the device to avoid interference from external sources in cities or near broadcasting towers etc.

• Detects Bluetooth, Wi-Fi, DECT, GSM, and RF
• Weight 1.00 - Unit Size 2.75 x 4.75 x .75
• Box Size 7 x 5 x 1.50
• Operation up to 20 hours - Power 2xAAA
• Frequency range, Antenna #1: 40MHz – 4Ghz. Antenna # 2: 2.44 GHz

User questions & answers

Question:	Does this device detect what direction the RF signals are coming from
Answer:	When scanning, the Visual/Audio Display will intensify the closer you get to the Transmitting Signal, so to answer your question yes. Once in range of outbound transmission and where detection tool brings you, a physical manual inspection of area of suspicion is required to determine if indeed a threat signal or authorized signal you know about..
Question:	Can this device find hidden camera's that do not transmit, but rather just record
Answer:	The DD1206 is designed to find transmitting devices and would not be the tool to use for self recording non wireless transmitting covert camera systems. A device such as the Spy Finder SF-103P would be the tool to use when looking for non transmitting covert camera systems as it allows the user to identify the covert lens using light reflection.
Question:	What does hunter sweeper mean
Answer:	Reference of devices capability to Hunt illicit signals of any hidden audio bugs, GPS trackers or other unauthorized wireless devices. This is a bug sweeper (hence the hunter sweeper)
Question:	Does this detects gps bugs
Answer:	Yes as long as it is on tracking mode. Details, The 1206i would pick up a GPS device if it is running on a GSM signal. The 1207i bug detector, however, will pick up a wider range of types of signals, so it would be better to pick up GPS trackers than the DD1206. The more popular one is the 1207i >> http://www.amazon.com/Professional-Multi-Channel-Detector-Wireless-Protocols/dp/B00THI6HAI/ref=sr_1_2?ie=UTF8&qid=1446831215&sr=8-2&keywords=dd1207

• Professional Grade. The perfect tool for searching for digital and analogue transmitters in the frequency ranges: Main antenna 40MHz – 4Ghz, Auxiliary antenna 2.44 Ghz, Increased sensitivity to Bluetooth/Wi-Fi signals allows the operator to detect wireless sources at distance of 50 cm- 2 m
• Detects ACTIVE GSM, Bluetooth, Wi-Fi and RF, 16-segment bar graph indicator providing a wide dynamic range, 4 work modes: silent, sound, vibration and mixed
• Correlation function discovers FM-transmitters by the presence of sound is different than other detectors this unit can produce a loop-back effect A microphone transmitter will pick up the sound and transmit the beep. The demodulation display will pick up the transmission and flash simultaneously. Also, when the unit detects other transmission different sounds will come from the unit depending the type of transmission it detects
• 2 levels of sensitivity (attenuator), Durable metallic body, Microprocessor controlled, Includes the extra antenna allowing the device to avoid interference from external sources in cities or near broadcasting towers etc.Detects Bluetooth, Wi-Fi, DECT, GSM, and RF, Operation up to 20 hours, Power 2Xaaa, Frequency range, Antenna #1: 40MHz – 4Ghz. Antenna # 2: 2.44 GHz

User questions & answers

Question:	What is the maximum range of this device
Answer:	Stitched!
Question:	Does this detect 5/5.8ghz wifi as well
Answer:	Yes, just click on the "CUSTOMIZE NOW" section and you will be able to add the name you want us to embroider on the backpack.
Question:	I am interested in identifying where the wifi gsm and bluetooth signals originate from in a new automobile. Will this be able to pinpoint this
Answer:	The Seersucker is cotton, so it has similar stain characteristics to regular cotton fabric. The inside is lined with stain and water resistant fabric, and the bag can be treated with stain remover and put in normal wash and dry cycles in normal laundry equipment.
Question:	will this device tell me if someone is on there cell phone and will it show a number
Answer:	No cup holders inside. Just a loose (not super supportive) flap along the back side which acts as a pocket separator for small items. Great quality backpack though!

The Discover It DD 1206 Will Detect:

All tracking, listening, and surveillance devices give off a unique frequency to relay whatever information is being absorbed back to another main device or central computer. This means that depending on the device, there will be a different frequency being emitted to relay this information.

Why Do I Need This Device?

GSM, Bluetooth, WiFi, and DECT Bugs are commonplace these days. The ability to place these minuscule devices into everyday objects is an immense threat to everyday security and the privacy of an individual. These enable people to listen in on every single sound you make whether you're talking business or personally. These threats are not the work of science fiction they are threats that far more people are susceptible than one would think.

What Makes This Device Better Than Similar Ones?

Most bug detectors out there will detect many of the same frequencies that the 1207 I does, but will not include the low energy transmissions that are produced by Bluetooth and WiFi. Ensuring the safety of your working, professional, or any type of environment is entirely possible with the 1206i. Don't gamble on safety and security, get a detector that will neutralize any possible bug threat.
