In een wereld waar reizen normaal is blijken infecties zich snel te kunnen verspreiden. De mogelijkheid om mensen op koorts te screenen is een belangrijk hulpmiddel om het risico op verspreiding sterk te verminderen. Het AMETEK Land vIRalert 2 Human Body COVID warmtebeeldcamera systeem meet hiervoor op afstand de temperatuur van het menselijk lichaam (meestal het gezicht) nauwkeurig en automatisch. Bij het waarnemen van een verhoogde lichaamstemperatuur wordt automatisch een alarm afgegeven. Hiermee wordt het risico op overdracht naar Uw personeel geminimaliseerd.
Door het warmtebeeld “realtime” te vergelijken met een uiterst nauwkeurige blackbody-kalibratiebron, kan het vIRalert 2 systeem nauwkeurig en betrouwbaar de huidtemperatuur meten. Door de snelle meting is deze dan ook geschikt voor screening in voetgangersgebieden, luchthavens, treinstations, ziekenhuizen, gemeentehuizen, bibliotheken, kantoorgebouwen, fabrieken en vele andere plaatsen waar infectie zich gemakkelijk kunnen verspreiden.
Het vIRalert systeem geeft op het scherm en eventueel een hoorbare waarschuwing wanneer een voorbijganger met een verhoogde temperatuur wordt gedetecteerd. Hierdoor kan eenvoudig worden besloten of een persoon verder moet worden gecontroleerd. Dit zonder de voetgangersstroom te vertragen of te onderbreken en bent u verzekerd dat iedereen wordt gemeten.

Considered on a case by case basis. We may want to prioritise hospitals and critical infrastructure.
Can I order a commissioning engineer?
This should not be required; the system is designed to work out the box and setup should be possible by any unskilled operator very quickly using the documentation and videos. Our customer support is currently available through existing channels, phone and website. We have a webchat facility online.
Is the system US HIPPA compliant?
No camera is specifically compliant or not, the burden is on the health provider to use Personal Health Information (PHI) responsibly. Our system does not provide high resolution facial images, and does not record data, and as a point of access system, is designed to be in public areas, where there are no restrictions.
What additional IO is available?
There is a standard Ethernet connection between the camera and laptop. Additional physical IO and digital output requirements can be quoted on a case by case basis. The standard system is designed as a quick, simple, low cost, off the shelf solution.
What temperature is the calibration source set to? Can I adjust it?
No, this is preset to 38 degrees Celsius
Does the system emit any harmful radiation?
No, it only measures infrared energy emitted from surfaces, it does not emit any radiation itself.
Can the system be used outdoors?
No, it is not IP sealed.
Are there any specific considerations for the installation?
Please ensure that: the calibration source is not mounted next to a radiator, the camera sees the person as the hottest object, not the background through the open door, make sure there are no radiators, heaters or other heat source e.g. hot power supplies or hot monitors in the FOV, the calibration source is not obstructed at any time.
Do ambient temperature swings affect the temperature readings?
The 38 °C calibration source is temperature controlled and permanently located within the field-of-view of the imager, so we always know the imager is showing the correct temperature. Body temperatures are essentially compared to the reference temperature. Human skin temperatures fluctuate depending on ambient conditions, so alarm thresholds are determined locally.1

Will we need to get an export licence?
Not subject to export licence requirements.
Are the Regions of Interest adjustable?
Yes, they are configurable to set an ROI around the calibration source and where the public will be. Instructions are available in the user guide.
Can I scan groups of people passing through the point of entry?
No. Each subject must be stopped so that they can stand, or sit, still and directly face the camera in order for an accurate temperature value to be taken.
How long does vIRalert 2 take to set up?
Typical setup time takes between 5 to 10 minutes on initial setup.
What is the setup configuration?
The typical detection distance is 1 metre. The Blackbody Source should be placed 1m from the Camera, then the subject must stand next to the Blackbody Source looking at the Camera, and both the subject and the Blackbody Source must be in the Camera frame at the same time. Failure to follow these distance guidelines may result in less accurate skin temperature readings.
What is required to operate vIRalert 2 in addition to what is included in the box?
A PC, laptop, or tablet running Windows 10 is required. Additionally, you will need a way to mount the Blackbody Source and the Camera. There are a variety of suitable options available that range from using standard camera tripods to more permanent installation options.
How do I download vIRalert 2 Software?
VIRalert 2 software can be downloaded from the vIRalert 2 product page.
Does the system require Wi-Fi?
No. The system does not require Wi-Fi to function. As mentioned above, AMETEK Land may update the software occasionally and provide a download option on our website.
How accurate is vIRalert 2?
VIRalert 2 has ± 0.5°C measurement accuracy aimed at an object with a temperature that is known and stable, such as a Blackbody Source. Unlike economical industrial thermal cameras, vIRalert 2 was developed and calibrated for precise skin temperature values and maximizes accuracy by referencing the Blackbody Source with a known temperature value. Note: Human skin temperature is affected by a wide number of environmental and physiological factors. Elevated facial skin temperature may signify a raised body core temperature; correspondingly, an elevated core temperature may not be accompanied by a raised facial skin temperature. vIRalert systems are accurate systems that must be operated strictly in accordance with the manufacturer’s operating manual.
Can vIRalert 2 be used to detect an illness, fever, virus or infection?
No. vIRalert systems are not intended, nor designed, to diagnose or detect medical conditions including, but not limited to, viruses or other illnesses. AMETEK Land thermal imaging products should only be used to detect variations of surface temperature. If elevated skin temperature is detected, the finding should be confirmed by other means, for example, an approved medical thermometer. The absence of an elevated skin temperature does not exclude a fever.
Can the system replace a medical thermometer?
No, medical thermometers are used by trained professionals for core temperature diagnostics. vIRalert 2 does not do this. VIRalert 2 measures the skin temperature of an individual and alerts the user when the subject’s skin temperature exceeds the user-selected threshold. VIRalert 2 can be used for screening and allows the operator to maintain a safe distance from the subject. VIRalert 2 does not take the place of a medical thermometer for measurement of a person’s body temperature to diagnose fever.
Does ethnicity affect the temperature values?
What affects skin temperature differences?
A few variables can affect HBTM differences. VIRalert 2 detects the hottest area of the face for temperature measurement. Sunbathing and exposures to other hot temperatures can increase the temperature of the skin temporarily, and perspiration, cool rainwater or cold wind on a face may temporarily cool a face. This should be taken into consideration when screening.
Why doesn’t your system display body temperature, which I am used to seeing on my thermometer?
VIRalert 2 is not a medical thermometer and it does not measure body temperature. VIRalert 2 displays your skin temperature at the warmest point detected on the face. The relationship between skin temperature and body temperature depends on multiple factors. However, screening for elevated skin temperatures above your population will have a high likelihood of detecting elevated body temperatures.
Do I need any special training to use vIRalert 2?
No, the software is simple to set up and easy to use.
Where should I set my alarm temperature threshold?
The temperature alarm threshold is user adjustable. Skin temperature may vary based on a variety of circumstances. For this reason, vIRalert 2 graphs all recent temperature measurements to help the user clearly see anomalies and set a desired temperature alarm threshold based on their own population and environment. By looking at this data the user can determine if they are setting the threshold at their desired screening level, typically a couple of degrees higher than where these measurements are clustered.
What should I do if someone has a temperature above the threshold I set?
The actions after the temperature measurement should be decided by the user.
Do I need the Blackbody Source in the frame?
Yes, this is required. The Blackbody Source enables vIRalert 2 to produce higher accuracy than a standard thermal imaging Camera. VIRalert 2 will not operate unless the Blackbody Source is detected in the Camera frame.
Does the Blackbody Source work with any other power sources?
No, please use the power supply provided by AMETEK Land in order to maintain the best performance of the system.
Can vIRalert 2 screen more than one person at a time?
No, the system is designed for a single person.
Can multiple systems be used with one computer?
VIRalert 2 supports one system per computer.
How much time does each scan take per person?
Measurement time is 1-3 seconds.
Does vIRalert 2 have audible alarms?
Yes. VIRalert 2 has an audible alarm when thresholds are exceeded.
Will a nearby heating and air condition vent affect the system?
Environments such as warm and cold conditions may affect temperature values. For best performance, we recommend installing this system inside a temperature-controlled environment. You should also avoid leaving the Blackbody Source in direct sunlight or near heat sources.
What type of lighting is required for the system to function?
Standard indoor lighting is needed for best results using vIRalert 2.
