Lie Detech Inc LTD

Lie Detech was founded in 2011. 

We produce the highest quality lie detectors in the market to date. Our technology is based on the most advanced techniques and methods used by Israeli security units. 

We strive to deliver top performance capabilities with 4 different measures for maximum accuracy. 

The online shop Liedetech.com sells high-quality polygraphs with four measurement methods. The product is characterized by its accuracy and compatibility with all Windows operating systems via USB port. 

For detailed descriptions of the functioning of our product you find under details.

This is the only polygraph that made by ISRAELI experts, MADE IN ISRAEL

LieDetech small version is made in ISRAEL which has adopted the newest and advanced technology in polygraph, it is used for providing strong evidence to prove the suspect his/her clearance. the language of the software is available in English, and we are always upgrading the new options .     

LieDetech is a great product that made in ISRAEL by Polygraph experts, which has adopted the newest and advanced technologies in the polygraph industry. The LieDetech developed based on secrets from the lie detection long years of experience.

LieDetech small version contains PCBA + MCU inside a plastic case and has embedded software for reading and decoding biological signals from the human body and transfer the information from the sensors to a windows PC. The fantastic combined of hardware and software the user receives simultaneously 10 different real-time parameters from the human body that connected to 6 most accurate sensors with the in a speed of 2400 bytes per second.     

LieDetech small version. You can connect the Liars LieDetech hardware to any Android devise that has OTG USB cable. Each LieDetech has its own serial numbers burned inside the hardware, preventing the possibility to fake the product. When using the LieDetech for the first time, the user must active the hardware from his PC, to make sure that the product is originally made in ISRAEL.

Functions and Features:

• There are 4 different physiological bio signals sensors, which can read the human body signals and do analysis of the psycho physiology parameters as follows:   
• 1. The volume of blood capacity in the peripheral skin – BVP (blood volume pulse amplitude for human fear analysis)  
• 2. HR heart rate and IBI (Inter Beat Interval in MSEC, increasing the pace - measure pressure and stress - fight or flight syndrome).
• 3. Dynamically relative blood pressure changes that measure of extremely tiny BP changes that indicates fear, stress, pressure, fight or flight, etc.
• 4. HRV (Heart Rate Variability) time domain calculation and FFT spectrum analysis provides 40 different psychophysiology and physiological indicators concerning mental and emotional state of the central autonomic nervous system activity. The most 4 common parameters are: "Rumination thoughts" (VLF), "Stress activation" (HF), "relax activation" (LF), "calm ratio" (LF/HF). 

The GSR sensor: Measuring the human galvanic Skin Response with 2 electrodes that connected to 2 fingers (2 and 4) for inspection of the sympathetic autonomic nervous system activity. The electric circuit is extremely sensitive and show values between 2000 to 60,000 in a very high-resolution measurement.

The Temperature Sensor: Measuring the peripheral skin temperature in 0.01 C resolution, when the skin temperature become lower - this is indicator for the general sympathetic nerve system state.

The Abdominal breathing sensor: A very sensitive stretch sensor based on rubber tube that measure the human abdominal breathing amplitude and breathing ratio per minute.

PC Software

• The PC software of the LieDetech enables our customer user to operate a professional polygraph test to anyone - very simple to use - very sophisticated technology include updating sequential questions (cold questions, hot questions and control question).
• The tester can update during running the test any kind of surround or background or inside artifacts that influence the recorded signals and that’s include the "artifacts timing" signed with a specific background color to indicate the situation. 
• During the polygraph test, all the raw data signals from the sensors and the analysis data concerned the questions and answers will be recorded and will be saved for future playback. The customer also can export all the data to .CSV files for his own analysis.

• LieDetech software not only can display the whole process on the PC screen, clearly showing the subject’s psychological movements, also enables load history tests and everything can be send to anyone that has our platform or as excel files for "second opinion" analysis. LieDetech Android APP enable your device (Android system) to read data from the hardware via a dedicated communication OTG cable, the Android device will be used as the power supply for the hardware and as a display screen for showing the subject body’s sniffing information.
• The APP has all the line charts display the raw data from the sensors on the phone screen, and sends some of the signals to our cloud servers.

The Liars Detector components:

• 1 X LieDetech data acquisition plastic box.    
• 1 X PPG - BVP heart rate sensor and blood pressure dynamic relative changes. 
• 1 X GSR electrodes cable with Velcro bands.
• 1 X Abdominal Breathing stretch sensor.
• 1 X Temperature sensor.
• 1 X USB cable - 30 cm long for connecting the device to the PC. 
• 1 X PC Polygraph Software.   
• 1 X Read Signals and raw data analysis Software.  

This is about time to improve your abilities by using the lowest cost and high-level technology from ISRAEL.

Open up your own business with polygraph tests

In the following case study, we give you an insight into the polygraph market. Currently, the segment performing polygraph tests for customers and prospects is just at the beginning. In the market average, a lie detector test is estimated at $449-1.200 per session.

With the purchase of only one lie detector, you can amortize the costs by just one customer.

The entire market about finding the truth is recording significant growth rates! Be part of it at the very beginning to become self-employed with lie detector tests. With only a few sessions a month, you already achieve an average worker's wage in US/EU.
