Converus EyeDetect

EyeDetect® is a next-generation lie detector. It measures subtle changes in the eye to detect deception. EyeDetect is internationally used to screen job applicants, employees, parolees as well as law enforcement and public safety personnel. It is less evasive and more cost effective than traditional polygraph examination which makes it perfect for large scale or discreet applicant screenings. Despite this, it still boasts an accuracy rating of 86%.

The process can be automated, which means that you can either employ the services of our Converus EyeDetect consultant, or you can purchase your very own Converus EyeDetect instrument and enjoy continued training and support from the PISA Pre-Employment Screening Centre team. Combined with a traditional polygraph examination in a successive hurdles approach it becomes the most powerful and accurate lie detection screening tool in existence.

Step into the future with the Converus EyeDetect integrity measurement tool.

Advanced lie detection technology in South Africa

How Does Converus EyeDetect Work?

The brain and eyes respond to deception. The greater the consequences of the lie, the greater the cognitive load. This affects the eyes. EyeDetect measures changes in pupil diameter, eye movement, reading behavior, blinks, fixations and other things. Using an infrared camera and complex algorithm, a person’s credibility score is calculated: truthful or deceptive. Participants answer True/False questions on a computer. The infrared camera records eye behaviors. When the test concludes, responses to questions and eye measurements are uploaded to a web server for immediate scoring. Those authorized can view results in the web-based Converus Dashboard. A Converus Credibility Score shows the probability the person was truthful.

EyeDetect Research


No sensors are attached to the participant, who answers True/False questions on a computer.



Test administrators can manage up to 3 EyeDetect stations simultaneously, and it is cheaper than a traditional polygraph test.


Simple to Use

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


Incorruptible & Unbiased

Participants are tested by computer. The test administrator cannot 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.


Flexible & Portable

One or more systems can be used at a time. The system is portable and can be carried to a regional or remote office for testing.

Advanced lie detection technology can be used for pre-employment screenings.

Available Across Africa

The instrument can be implemented across Africa. The test can be conducted by having the questions presented visually or using audio, and can be adapted to any language. This means that the Converus EyeDetect test can be implemented across the globe with relative ease. Never before has it been so easy to conduct large scale pre-employment applicant screenings. You too can own your very own Converus EyeDetect instrument and enjoy the advances of lie detection technology in your own company.
