EyeDetect+: Best Lie Detector | Converus: The eyes don't lie.

EyeDetect+ by Converus is the most accurate lie detector available today. Find out the truth quickly and easily by looking at the eyes. The eyes don’t lie.


EyeDetect + Physio Tracker = EyeDetect+

Functionally Identical to Polygraph

EyeDetect+ is a combination of EyeDetect and the Physio Tracker. An optional add-on device, the Physio Tracker attaches to an examinee’s fingers during an EyeDetect test. It records the same data as a standard polygraph instrument, including:

   + Electrodermal Activity or EDA

   + Cardiovascular Activity
    _ Blood volume pulse (BVP)
    _ Heart rate beats per minute (BPM)

   + Respiration Activity

Legally Compliant Worldwide

Because EyeDetect+ is functionally identical to polygraph, it meets the legal definition of “lie detector” in most jurisdictions. But, unlike polygraph, it is always scored by algorithm—so it has perfect reliability. It also has 88 to 90% validity.

The eyes don’t lie®

Try EyeDetect+ for screening tests with 88% accuracy or diagnostic tests with 90% accuracy.

How Does EyeDetect+ Work?

EyeDetect Station

The body responds to deception. The greater the consequences of the lie, the greater the emotional reaction and increase in cognitive load. This affects the brain and body. EyeDetect+ measures changes in the eyes, heart, lungs, and skin.

Participants answer True/False questions on a computer. The infrared camera records eye behaviors. The Physio Tracker records cardiovascular activity, skin conductance, and respiration activity.

When the test concludes, all of that data are uploaded to a secure web server for analysis. A person’s credibility score is immediately calculated and available in a web-based Dashboard. The results are simple: truthful or deceptive.

What is the Physio Tracker?

The Physio Tracker is a device with three cables that measures 2.5” x 3.5”. One sensor uses two cables to measure Electrodermal Activity (EDA) and the other sensor is a photoelectric plethysmograph (PPG). It’s powered by a USB cable connected to the EyeDetect Station.

The Physio Tracker is an optional add-on to the EyeDetect Station. It can be used with any EyeDetect test. When not used, standard test scoring is performed. When used, enhanced test scoring is performed.

Features and Benefits of EyeDetect+

Highly Accurate

Lab and field studies show EyeDetect has an accuracy range of 88 to 90%, depending on the test administered.

Fast Results

Tests take 15 to 30 minutes and reports are ready in less than 5. Reports include a credibility score and details showing participants’ responses to questions.


No sensors are attached to the participant to monitor the eyes. The Physio Tracker attaches to three fingers.


Test proctors are trained in a few hours. One person can monitor and manage up to 3 examinees simultaneously.

Simple to Use

The participant follows onscreen instructions. A practice session helps to get comfortable with the test.


In an average 8-hour workday, one test proctor with three EyeDetect stations can run 40 tests. Quickly screen many people with great results.

Incorruptible & Unbiased

Participants are tested by computer and results are scored by algorithm. No one can alter test results. Test data is encrypted and tamper-proof.

Bank-Level Security

EyeDetect uses encryption and physical security that banks use. Data are encrypted and stored using military grade 256-bit AES / CBC mode encryption.

Complete Analytics & Reporting

Authorized personnel have access to test results via web browser. Results can be sorted by date, department, test type, credibility score, and more.

Flexible & Portable

The system is portable and can be carried to a regional or remote office for testing.
