Page 15: Applications And Features
1.3 Applications and Features Thank you for purchasing an Optotherm Thermoscreen System, designed specifically for mass human fever screening. Thermoscreen provides a fast and noninvasive way to detect individuals with elevated Facial Skin Temperature that may indicate a fever. Thermoscreen is best utilized as the first of a two-point procedure for identifying feverish individuals. At the entrance to crowded areas, Thermoscreen can be used to detect individuals whose Facial Skin Temperature is higher than normal.
Page 16 Advantages over using Medical Thermometers Alone Thermoscreen can screen over 1000 subjects per hour, more than 10 times the screening rate  using Medical Thermometers alone. Thermoscreen screenings do not require contact with subjects and are conducted at a distance. ...
Page 17 Because Skin Threshold can vary depending on time of day and on other factors affecting specific Subject Groups, such as the temperature and humidity to which a group has been exposed, individuals are evaluated based on Screening Measurements of previously screened subjects, not on a fixed temperature threshold.
Page 18: How It Works
1.4 How It Works Thermoscreen operates by detecting and quantifying the LWIR energy that is continuously being emitted from human skin. Thermoscreen operates in real-time, capturing Thermal Images at a rate of 60 frames-per-second, and is capable of evaluating thousands of individuals per hour so as not to restrict pedestrian flow.
Page 19 measurement is conducted, and the Screening Results are displayed and announced. Subjects whose Facial Skin Temperature is equal to or above the Skin Threshold are instructed to "please wait here for an attendant" and a large FAIL button illuminates on the screen. Subjects whose Facial Skin Temperature is below Skin Threshold are given the message "thank you, you may proceed"...

1.5 Thermoscreen Accessories Mobile Computer Stand The Mobile Computer Stand (see figure 1.5.1) provides a convenient way to operate, transport, and store the Thermoscreen System and allows the fever screening station to be easily moved to alternate locations to screen additional areas or to accommodate changes in pedestrian traffic.
Page 21 Portable Screening Wall The Portable Screening Wall (see figure 1.5.2) can be placed behind the Screening Zone to prevent reflective or hot background objects from affecting Screening Measurements. This foldout wall is comprised of three acoustical panels that are connected with 360-degree hinges. Each panel is wrapped with acoustical flame retardant fabric and secured by an aluminum frame.

Page 23: Site Setup
2 Site Setup 2.1 Site Conditions The preparation of the fever Screening Area requires careful consideration. Incorrect site selection can affect the accuracy of Screening Measurements. Thermoscreen measures the Facial Skin Temperature of subjects, which is not only dependent on Internal Core Temperature but also on many factors including ambient air temperature and humidity.
Page 24 Screening Zone Background The area within the field-of-view of the camera must be free of hot or reflective objects. Except for the subject to be screened, there must be no other persons in the scene. Use the portable screening wall to block unwanted objects or people in the background (see section 3.5 Portable Screening Wall).

Page 26: Operator Training
Manual Screening Mode Protocol This screening mode can be subdivided into two categories: individual and continuous screening. Individual Screening Individual screening requires each subject to stand still at a fixed distance from the camera while being screened. This screening method is employed in situations that require more detailed and careful screening and when stopping subjects briefly does not cause problems.
Page 27 2.4 Example: Manual Screening (Individual) A Thermoscreen System is placed at the entrance of a school to screen students and visitors upon entering the building (see figure 2.4.1). When operating in Manual Screening Mode and requiring each individual to stop briefly to be screened, a single Thermoscreen station can effectively screen up to 1,200 subjects per hour.

Page 70: Key Concepts
5 Key Concepts 5.1 Skin Offset Facial Skin Temperature - Internal Core Temperature Correlation Studies have shown that there is a correlation between Internal Core Temperature and Facial Skin Temperature. The maximum temperature measured between the eyes usually provides the best correlation with Internal Core Temperature for the following reasons: 1.
Page 71 Manual Screening Mode When screening subjects in this mode, Skin Offset can be calculated using the Measure Skin Temperature Offset window (see figure 7.6.1). During this procedure, both Thermoscreen and Medical Thermometer measurements are conducted on a number of test subjects. Skin Offset is determined by calculating the average difference between the Medical Thermometer and Thermoscreen measurements.
Page 72: Fever Threshold
5.2 Fever Threshold Internal Core Threshold is the threshold, often 38°C (100.4°F), used by medical practitioners to indicate a fever when using a Medical Thermometer. However, studies indicate that the threshold for a fever can vary depending on a number of factors such as age, gender, time of day, activity level, and clothing. For this reason, the threshold for a fever should be determined based on the characteristic of specific subject groups.
Page 73 The value of Fever Threshold depends on the specific requirements of your particular fever screening operation. For example, many hospitals are able to conduct more thorough fever screening evaluations because they have sufficient personnel available to handle large numbers of False Violations. Hospitals, therefore, would typically set Fever Threshold lower in order to minimize Missed Detections.
Page 74: Measuring Internal Core Temperature
5.3 Measuring Internal Core Temperature Internal Core Temperature can be measured using one of the following Medical Thermometers: Electronic or conventional glass mercury thermometers for oral, axilla (under arm), and rectal  measurements Tympanic (ear) thermometers  Studies demonstrate that the range of normal Internal Core Temperature is much wider than is generally understood.

Page 114: Excluding Background Objects
7.4 Excluding Background Objects In most cases, there should be no heat sources or reflective objects within the camera’s field of view. When such objects cannot be removed or blocked, regions allow you to exclude areas so that they don't interfere with the Screening Process.
Page 115: Person Detection
7.5 Person Detection Note: Person Detection settings are available in the Fever Screening Setup window. The detection of a subject begins the Screening Process. This condition is met when a temperature equal to or above Person Detection Temperature is detected within the Screening Zone.
Page 116: Measuring Skin Offset
7.6 Measuring Skin Offset When operating in Automated Screening Mode with the Automatic Skin Offset: Enable box checked, Skin Offset is automatically calculated as subjects are screened. However, when operating in Manual Screening Mode (or Automated Screening Mode with the Automatic Skin Offset: Enable box unchecked), effective fever screening requires accurate measurement of Skin Offset using a Medical Thermometer and the Measure Skin Temperature Offset window (see figure 7.6.1).
Page 117: Adjusting Skin Offset
Measuring Skin Offset Calculate Skin Offset according to the following procedure: 1. Open the Measure Skin Temperature Offset window by clicking the Measure Skin Offset button in the Fever Screening Setup window. 2. Click the Clear All Rows button to delete any existing data. 3.
Page 118: Adjusting Fever Threshold
7.8 Adjusting Fever Threshold Fever Threshold regulates the number of Missed Detections and False Violations. In many fever screening applications, Fever Threshold may not need to be changed. Operators can periodically adjust this setting however, to regulate the number of Missed Detections and False Violations (see section 5.2 Fever Threshold).
Page 119: Fever Threshold Violations
7.9 Fever Threshold Violations A Fever Threshold Violation occurs when a subject’s Internal Core Estimate exceeds Fever Threshold. Screening Violations Window The Screening Violations window (see figure 7.9.1) displays Violation Images: Thermal and Visual Images that were captured during the previous three Fever Threshold Violations. Display this window by pressing the Violation Review button in the Screening section of the toolbar at the top of the Thermalyze window.
Page 120 Violation Review Window The Violation Review window (see figure 7.9.2) displays the Violation Image and Violation Sequence that was selected in the Screening Violations window. Display this window by pressing the Violation Review in the Screening section of the toolbar at the top of the Thermalyze window. The date and button time the violation occurred is displayed above the image.
Page 121 Fever Threshold Violation (Manual Screening Mode) This section describes the events that occur during a Fever Threshold Violation when operating in Manual Screening Mode. Many of these events however, also occur when operating in Automated Screening Mode. See section 7.10 Automated Screening Mode for events specific to operating in Automated Screening Mode.
Page 122 Violation Image files are saved in a day folder that is contained within a year month folder that is located in the Images directory. For example, the Violation Image file Optotherm\Thermalyze\Images\2020 8\24\085427.oimg was saved on August 24, 2020 at 8:54:27 am. Violation Sequences and exported images are similarly saved in the Sequences and Export directories.
Page 123 Fever Threshold Violation Confirmation When a Fever Threshold Violation occurs, the operator should examine the most recent Violation Image in the left of the Violation Review window to verify that the violation occurred on the subject’s face, and not on hair, clothing, or on an object in the background. Observe where the colored pixels are located. If they are located on the subject’s face, the operator can be confident that a valid Fever Threshold Violation has occurred.
Page 124: Automated Screening Mode

This mode of screening provides the following features and advantages over Manual Screening Mode: Face detection  Movement detection  Audible verbal commands ...
Page 125 Automated Screening Mode Process 1. When at least one pixel with Person Detection Temperature has been detected within the Screening Zone, the PERSON indicator illuminates, and the subject is instructed to "please stand still and look directly at the camera.” Thermalyze examines the number and shape of the pixels with temperature above Person Detection Temperature to determine if the subject’s face is in view.
Page 126 Face Detection Brackets Colored brackets are displayed around those pixels whose temperature exceeds Person Detection Temperature (see figure 7.10.1). A status message is also displayed above the brackets. Figure 7.10.1 – Face detection brackets Page 125 of 145 Thermoscreen User Manual 2020-03-09...
Page 127 The status message and the color of the brackets indicates the status of the Screening Process and can be helpful when determining the reason for any problems when setting up fever screening parameters. Screening Process status messages are also displayed at the bottom of the Screening Results window. Bracket Message Description...
Page 128 Automatic Skin Offset In Automated Screening Mode, Skin Offset can be automatically updated to compensate for changes in ambient temperature and for variations in the Internal Core Temperature due to Circadian Cycle effects. Because a number of Screening Measurements must be conducted before Skin Offset can be re- calculated, when screening the first subjects, the value of Skin Offset is the value used during the previous screen.
Page 129 1. Create a sound file approximately four seconds long instructing subjects prior to being screened to “Please stand still and look directly at the camera.” Name the new sound file Stand Still Custom.wav and place it in the Program Files\Optotherm\Thermalyze\Sounds folder. 2. Create a sound file approximately three seconds long instructing subjects whose Screening Result = Pass to “Thank you, you may proceed.”...

Air bulb blower  Lens cleaning solution  Wiping cloth  Cotton swabs  Precautions To protect the lens from damage, follow these guidelines. Never touch the lens with hard or abrasive objects.
Page 131: Cleaning And Disinfection
8.2 Cleaning and Disinfection Important Concepts Cleaning Cleaning removes germs, dirt, and impurities from surfaces or objects. Cleaning works by using soap (or detergent) and water to physically remove germs from surfaces. This procedure does not necessarily kill germs, but by removing them, it lowers their numbers and the risk of spreading infection. Disinfecting Disinfecting kills germs on surfaces or objects.
