X Three Surveillance is a leading Manchester-based private investigator. We are experts in lie detector tests. We use Eye Detect lie detector tests to deliver and validate results. Eye Detect has distinct advantages over conventional polygraph tests. The test works faster and can be easily administered, and most of all, the results record very high levels of accuracy.

Eye Detect Results are –
The EyeDetect system boast a 91% and above accuracy compared to the Polygraph at a height of 83% (Depending on the test examiner)
The intelligent equipment uses infrared rays to understand various metrics associated with the Eye. Then, a series of algorithms are used to assess these metrics to tell whether the person is lying or speaking the truth.
The physiological basis of the test is that both the human brain and the eyes reflect mental burden or stress, also referred to as ‘cognitive load.’ Scientifically, it has been proven that when a person deceives, they are under mental overload or stress levels increase. The eyes reflect these telltale signs.
In Eye Detect, the machine records different ocular data of the examinees as they answer ‘True’ or ‘False’ to each question. Details that are captured are –
The responses and the different eye characteristics are uploaded to a web server. The data is evaluated with standard parameters, the test score is recorded, and the results are made available almost instantly.

Yes, however Bi-focal, Tri-focal and progressive lenses are no to be worn, we can supply 1.5 X reading glasses to take the test however during the test all test questions and explanations are read out for you by the computer.
Yes, However some drugs affect the pupils too much to administer the test such as opioids. Any drugs prescribed or not should be withheld for 24 hours prior to testing if this is possible. The Eye Detect will know if a persons eye does not react normally, when the test is scored they will fail the test for using a countermeasure.
Yes, the Eye Detect system can be used for people with Esotropia, Exotropia, Hypertropia and Hypotropia, however the initial set up and calibration may take 5 minutes more.
No, the EyeDetect system is single issue test, this means that we can only test for one accusation per test, this make the test extremely accurate. In most cases such as infidelity, theft and sexual contact we get a summary of the events and accusations from you, then the examinee will answer True or False to questions from that summary. This also speeds up the process of having a lie detection test.
