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.

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.

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.

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 accurate are thermal imaging camera kiosks? What is the margin of error?

The margin of error on the kiosk system is ±.54° F, unless it is medical grade.

Where on the face does the Elevated Temperature Detection Kiosk read a temperature?

The kiosk measures a persons body temperature on the forehead.

How far from the camera field can it read a subject’s temperature?

The kiosk can detect an elevated body temperature from 2-5 feet away.

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.

What are the database capabilities of the kiosk?

The kiosk database has a limit of 30,000 images.

How many kiosks can I put on one server?

There are no limitations on how many kiosks can be added to one server.

Can the kiosk be used for access control, facial dection, and/or biometric time clock?

Yes. The system has full access control, facial recognition and biometric time clock capabilities 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.

How accurate are passive moving systems? 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. 

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.

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.

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.

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.

Will the passive 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.

Do I need to have a server with the passive system?

Yes, our passive system requires a server.

How many passive systems can I put on one server?

The maximum number of passive cameras on one server is two. 

Can a database be imported into the system for facial recognition?

Yes. Our passive moving thermal system utilizes facial detection and has facial recognition capabilities for those loaded into the database.


Where on the face do thermal handheld devices read a subject's temperature?

The handheld thermal camera 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.

Can I review photos on the handheld device?

Yes, there is a playback feature.

How are the images stored on the handheld thermal screening device?

The images are stored on a Micro SD card.

How long does the battery last?

The battery can last from 8-10 hours of continuous operation.
