Liars Detector 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 .
Liars Detector has a printed electronic circuit and micro processor PCBA MCU which has a reading software for decoding information and transferring the information from the sensors to the windows PC and Android Mobile Phone . Due to the combined hardware with software working which allows the user to receive simultaneously all seven signals from 6 sensors with the most accurate CAB information at 420 signals per second .
Hardware has a built-in microchip NFC for originally confirmation and for warranty approve, the hardware is connected to an Android phone with OTG USB cable that also supply the power to the hardware, the most important ,each Liars Detector has its own serial numbers ,preventing any possibility of fake one produced . When the first time of using , users have to active the operation via s PC or his Android phone which can make sure the goods which is originally made in Israel .
Functions and Features :
There are Six different physiological sensors, which can read the human body bio signals and do analysis of the psycho physiology parameters as follows : The PPG sensor (Penile plethysmography) and the analysis:
1. The volume of blood capillaries BVP (Blood Volume Pulse DC amplitude equal to the human fear level).
2. HR heart rate and IBI (Inter Beat Interval, increasing the pace - measure pressure and stress - fight or flight syndrome).
3. Dynamically real time high resolution blood pressure changes monitoring (measure of tiny BP changes 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 metal and emotional state of the central autonomic nervous system activity.
The GSR sensor:
Measuring the human galvanic Skin Response with 2 electrodes that connected to the human fingers for inspection of the sympathetic nervous system activity. The electric circuit is very sensitive and show values between 2000 to 60,000 very high resolution measurements.
The Temperature Sensor:
Measuring the peripheral skin temperature in 0.01 C resolution when the skin temperature become lower - this is another indicator for the sympathetic nerve system activation.
The Abdominal breathing sensor:
A stretched very sensitive sensor based on silicon rubber cord that measure the human abdominal breathing amplitude and breathing ration per minute .
The Chest breathing sensor:
A stretched very sensitive sensor based on silicon rubber cord that measure the human chest breathing amplitude and breathing ration per minute .
The Air pressure input tube sensor (anti cheat sensor):
A general "air pressure input" measurement sensor, very sensitive, high resolution and fast response that can measure any kind of input of "air pressure changes" such as: Blood pressure cuff, air pillow, hand base etc, for monitoring movements and other techniques that people are using to try to cheat the polygraph.
