NO-CONTACT ELEVATED BODY TEMPERATURE DETECTION
Frequently Asked Questions
What are the different types of thermal imaging systems that Homeland Safety Systems offers?
Handheld, Kiosk & Passive Moving Camera Systems.
Can thermal imaging cameras be used to detect a virus?
While thermal imaging cameras cannot detect or diagnose a virus, they can alert you to an individual’s elevated body temperature which may indicate the presence of a fever, a symptom of viruses including Covid-19.
How accurate are thermal imaging cameras? What is the margin of error?
The margin of error on the passive camera systems, according to many international standards, is ±0.54° F. Through correct calibration, we have been able to reduce this to ±0.3° F on average. The margin of error on the kiosk system is also ±.54° F unless it is medical grade.
Will the system still give accurate readings in an enclosed space that is not climate controlled?
We recommend that the system is used in a controlled environment specifically because the system must be calibrated to the ambient room temperature. Although the system can give an accurate reading in an enclosed space that is not climate controlled, margin of error will increase as the ambient room temperature changes from initial calibration.
Can a database be imported into the system for facial recognition?
Yes. Both the kiosk and the passive moving thermal camera system utilize facial detection and have facial recognition capabilities for those loaded into the database.
Can the kiosk be used for access control and/or biometric time clock?
Yes. The system has full access control capabilities with facial recognition and biometric time clock for those loaded into the database. The kiosk can also provide complete audit trails of those entering the facility.
Is there a way to push alerts to a mobile device, tablet, or laptop?
Yes. Notifications can be pushed to any of these devices.
What is the purpose of the blackbody device?
While only a small part of the passive camera system, the blackbody calibration tool consists of a reference point whose temperature is precisely known and controlled. The blackbody device is a necessary component to detect an elevated body temperature and will ensure accurate & reliable temperature readings are produced during continuous operation of the system.
Do I need to use a blackbody for elevated body temperature screening?
Including a blackbody in the camera’s field of view can significantly improve the system’s performance but is only required for use with our passive camera systems. The kiosk and handheld versions are all inclusive and do not require the use of a blackbody calibration device.
Would this system violate any HIPPA regulations if installed at a hospital or doctor’s office?
No. The temperature readings are not considered medical information and only an estimate, therefore, it would not violate any HIPPA regulations regardless of the location it is installed. This thermometer is intended for screening individuals or monitoring an individual for potential elevated skin temperatures and should always be followed up with additional screening by a medical professional if EST is recognized. Homeland Safety Systems thermal imaging camera systems are currently installed and being used in several hospitals, schools and industrial facilities across the southern region.
Can I install a thermal imaging camera system myself?
Our systems are designed as a one-on-one system and will require the same level of engineering, professional installation, and setup from our certified technicians as all of our equipment.
What is the lead time to receive a system?
The current production time is 4-6 weeks, although we are dedicated to helping you in any way that we can.
How many people can walk in front of the passive camera at once and it still read their temperature?
The passive thermal camera system can process temperature readings every 200 milliseconds which allows a large group of people to walk past the camera at a normal walking pace. Although it can process multiple temperatures at one time, a single line format is recommended to reach the most accurate results.
Where on the face do Elevated Temperature Detection cameras read a temperature?
For the passive camera system, temperature is measured at the tear duct (inner canthus) as this location provides the closest temperature correlation to human core body temperature. The kiosk measures temperature on the forehead and the handheld detects the hottest point of measurement within the field of view.
How far from the camera field can it read a subject’s temperature?
The handheld thermal scanner can detect an EBT from 1-3 feet away, the kiosk can detect from 2-5 feet away, and the passive can detect up to 15 feet away with the closest reading being next to the blackbody.
Can the kiosk detect whether or not someone is wearing a mask?
Yes. Not only can it detect a mask, but it can also detect inaccurate masks. The kiosk algorithm for mask detection is reliant on the mask blocking the thermal signature from an individual’s face. If a mask is inadequate or too thin, it will not block the thermal signature and the kiosk will not detect the mask.
Do I need to have a server with the kiosk or passive system?
Our kiosk system does not require a server and operates as a standalone unit reconfigured by Homeland safety systems, Inc. The passive system does require a server.
How many kiosks can I put on one server? How many passive systems can I put on one server? Can I put a kiosk and passive system on the same server?
There are no limitations on how many kiosks can be added to one server, but the maximum number of passive cameras on one server is two. Although the kiosks and passive camera can be added to the same server, they will not be visible on one server at the same time because they use different software/web interfaces.
What are the database capabilities of the kiosk?
The kiosk database has a limit of 30,000 images.
How long does the battery last on a handheld thermal scanner?
The battery can last from 8-10 hours of continuous operation.
How are the images stored on a handheld thermal screening device?
The images are stored on a Micro SD card.
Can I review photos on the handheld device?
Yes, there is a playback feature.
How much does the installation and training cost?
Training is complementary with the purchase of an Elevated Temperature Detection System from HSS. Installation costs will vary according to installation requirements and job specifications. Homeland Safety Systems offers free site surveys in order to develop the most accurate quote for your needs.
