Frequently Asked Questions - Elevated Skin Digital Watchdog

How does thermal imaging technology work?

Thermal imaging cameras detect the heat radiation emitted by the skin. The DW E.S.T. system uses this to measure surface skin temperature as a non-contact pre-screening tool.

Can the DW E.S.T. system detect COVID-19 or other viruses?

No. The system is not designed to detect or diagnose any infection. It only measures skin temperature. Elevated readings should be followed by secondary screening with a medical thermometer and health questionnaire.

Do I need a Blackbody for the camera?

It is highly recommended to use a Blackbody for continuous auto-calibration. Without it, the camera may still function but with lower accuracy. The Blackbody provides a reference temperature of 104°F (40°C) to improve precision.

What is the temperature accuracy of the system?

With a Blackbody, the accuracy is ±0.36°F (±0.2°C). The system also requires proper installation and environmental conditions to achieve this accuracy.

How many people can be screened at the same time?

For best accuracy, screen one person at a time, with a maximum of 1 face every 4 seconds. Multiple faces may be detected, but only the highest temperature is shown.

Can the camera be used outdoors?

Indoor use is recommended. Outdoor deployment requires shelter from direct sunlight and weather, with ambient temperature between 50°F and 95°F. The Blackbody is not rated for outdoor use.

Is the DW E.S.T. system classified as a medical device?

No. The system is not a medical device. It is intended for supplemental screening only. It complies with FDA enforcement policies for thermographic systems but does not diagnose diseases.

How do I connect the camera to my computer?

Connect the camera directly to the PC via an Ethernet cable (CAT.5E UTP). The default camera IP is 169.254.100.100. Set your PC to a static IP in the same subnet (e.g., 169.254.100.1) with subnet mask 255.255.0.0.

How do I install the monitoring software?

Download the Elevated Skin Temperature System installer from Digital Watchdog's website. Run the setup, choose installation options, and ensure Bonjour is installed if prompted. After installation, launch the software and select whether a Blackbody is present.

How do I calibrate the camera?

With a Blackbody, the software auto-calibrates in real-time. Ensure the Blackbody is visible in the camera's field of view. If detection fails, you can manually draw a yellow square around the Blackbody. For cameras without Blackbody, use the Offset setting to adjust temperature readings.

The recommended location for the Blackbody installation: The Blackbody cannot be installed in a crowded location. Install the Blackbody within the red ellipse marked within the image on the left. This is the best location for on-site constant auto-calibration for accurate temperature measurements ( ±0.36^ F/0.2°C).

If the mouse cursor is left motionless on the thermal camera's view for more than one second, the system will display the screened temperature for that area.

8.8. Blackbody Status

The Blackbody status bar at the bottom of the software window will display only if Blackbody was selected as part of the solution when installing the software.

When mounted correctly in the camera's FOV, the Elevated Skin Temperature Software automatically detects the Blackbody's location.

If the automatic detection of the Blackbody fails and "Blackbody Status" continues to display "Blackbody: Detection failed", use your mouse and manually draw a square around the Blackbody. It will appear yellow. Place the square on the Blackbody as seen in the thermal video. You can adjust the size and position of the yellow square as needed by clicking and dragging the yellow square with your mouse.

When the Blackbody is detected manually, the "Blackbody Status" status will change to "Blackbody: Manual Detection". When this occurs, the "Restart Detection" button is activated. Click on it to set the program to find the Blackbody automatically. Once done, "Blackbody: Detection Success" will appear if the software successfully detected the Blackbody, or "Blackbody: Detection Failed" if the software fails to detect the Blackbody.

* Specifications are subject to change without notice.

NOTE: To increase the skin temperature measurement accuracy, the camera transmits raw temperature data of all the pixels in the thermal sensor to the PC software via the Ethernet cable. The Elevated Skin Temperature Software program processes the raw data using the PC's processing capacity.

If the installation includes a Blackbody, the temperature data in each pixel is calibrated based on the 104°F (40°C) temperature of the Blackbody. This increases the system's accuracy up to ±0.36°F/0.2°C.

The Elevated Skin Temperature Software program performs various analyses to mark a person's faces and skin temperature, on images from both the visible and thermal cameras.

11. FAQs

11.1. Usability

1. How does thermal imaging technology work?

a. Skin temperature pre-screening cameras detect the skin's heat radiation. When used properly, DW's E.S.T. cameras can be used as a non-contact pre-screening tool to detect differences in skin surface temperatures.

1. Can DW's EST system be used to detect a virus such as the novel Coronavirus (COVID-19)?

a. No, thermal imaging and skin temperature capturing cameras cannot be used to detect or diagnose an infection. DW's E.S.T. cameras can be deployed in public spaces such as school entrances, airports, and hospitals as an effective tool for measuring skin surface temperature. People identified as having an elevated skin temperature should then be screened by medical professionals using additional tools such as a thermometer and a health questionnaire.

1. Can I use the camera to get alerts without connecting it to a VMS, just with a laptop and browser?

a. The camera comes with an LED strobe included that can be mounted on the camera or next to it. Also, the camera has an additional alarm output that can be triggered by a temperature event.

1. Do I need to use a switch with the camera to connect it to a PC and can I use a PoE switch?

a. You do not need an additional switch or PoE switch for the camera. Connecting the camera directly to the PC lets the camera transmit the raw pixels directly and instantly to the PC.

1. How should skin temperature screening be performed?

a. The U.S. Food and Drug Administration (FDA) provides full recommendations for Thermal Imaging Systems (Infrared Thermographic Systems / Thermal Imaging Cameras). Here are several tips to ensure optimal measurement performance:

- Screen people, one at a time to look for temperature anomalies.

- Screen people from 10 to 16.4 feet away.

The camera measures the skin temperature near the tear duct. This location provides the closest temperature match to the human core body temperature.

IMPORTANT: This is not measuring core body temperature and readings near 35°C (95°F) are common.

○ Perform a secondary screening on individuals with elevated skin temperature using a medical device such as a thermometer and a health questionnaire.

1. How many peoples' temperatures can be measured at the same time?

a. In compliance with industry standards and to achieve specified accuracy, 1 face at a max of every 4 seconds.

1. How accurate is the temperature measurement?

a. With Blackbody, the camera has a temperature accuracy of +/-0.36°F (+/-0.2°C).

1. Can the camera measure in both Celsius and Fahrenheit?

a. Users can customize their view on the monitoring software by selecting the temperature values as Celsius or Fahrenheit. The software will display the measured temperature in the selected option.

1. Is it possible to switch a relay in the camera when a high temperature is detected?

a. Users can select Normally Open or Normally Closed activation of a relay. The monitoring software will display the selected preference.

1. Can the camera work outside?

a. It is recommended to set your screening station indoors. Solar loading or reflection could cause

false alarms and measurements.

b. If an outdoor deployment is the only option, both the camera and Blackbody need to be installed under a shelter. The temperature around the camera and Blackbody should be between 50^ F – 95^ F ( 10^ C – 35^ C).

NOTE: the Blackbody is NOT rated as an outdoor device.

1. Do I need to display specific signage to alert customers that their temperature is being measured? a. Check with your local government guidelines. Each location may have different standards and requirements for public notification. Users are responsible for compliance with any local standards and requirements.

11.2. Hardware Related

1. What does the Blackbody do and why do I need it?

a. A Blackbody is a sensor that constantly emits a heat signature between 0.90\~0.99. It is used as a reference source for the camera. When placed across from the camera, at the corner of the camera's FOV, it helps maintain the camera calibrated at all times, increasing data accuracy. Once the Blackbody is mounted properly in the camera's FOV, the E.S.T. monitoring software auto-calibrates in real-time with the temperature from the Blackbody and uses this to provide automatic, ongoing calibration and thermal drift management. This helps reduce false alarms and error readings.

1. Do I need a Blackbody for the camera?

a. The E.S.T. solution can be purchased as a complete kit, with one Blackbody and one camera. You may purchase a camera without the Blackbody. All DW cameras come calibrated from the factory. It is highly recommended to use at least one Blackbody per installation to guarantee proper calibration and accurate data is collected.

1. How do I test the camera to see if it is reading the temperatures correctly?

a. A comparison test with a handheld thermometer can be done at the site to verify the camera's accuracy.

1. How often do I recalibrate the camera?

a. All cameras are calibrated by default at the factory. Once mounted with the Blackbody, the camera can perform the calibration automatically and in real-time. It is recommended to calibrate your camera at least once a week for optimal performance. Users can also use the monitoring software to re-detect the Blackbody in the camera's FOV should there be any detection issues.

1. Does the camera need any type of software support agreement?

a. There is no need for a software support agreement for the camera itself. A 2-year warranty is included for the camera; however, a software support agreement is needed for the Video Management System platform if the camera is integrated.

11.3. Compatibility

1. Which Video Management Systems is the camera compatible with?

a. The camera is compatible with DW's E.S.T. monitoring software. This is a standalone solution that can be installed on any computer running Microsoft OS.

1. Can I connect my E.S.T. Solution to an Access Control system?

a. Yes, the camera has an output which switches on alarm. This output can be connected to and access control system controller which has input available.

1. Does it also work with facial recognition AI?

a. No. The camera uses face detection to perform temperature testing but does not support Facial Recognition.

11.4. Compliance

1. Is the solution classified as a medical device?

a. No. In the USA, the camera and Blackbody have been designed to meet the U.S. Food & Drug Administration's April 2020 Enforcement Policy for Thermographic Systems. However, it is NOT classified as a medical device and is not intended to detect or diagnose a disease or any health conditions. The product is intended to use as a first-line filter to identify people entering a facility who may have an elevated body temperature. If elevated skin temperature is detected, organizations should always follow up with additional screening with medical devices such as a thermometer and medical questionnaire. Organizations should then determine the appropriate action for that information. Temperature measurements should not be the only or primary tool of diagnosis or exclusion diagnosis of COVID-19 or any other disease.
