Baltimore, Maryland – USA
The market has been flooded with thermal camera systems often sold through US distributors posing as manufacturers. However, most are made by one company in China, all of which are making unsupported claims involving being able to scan multiple objects, scan individuals with hats and glasses, and scan outdoors. A complaint was filed with the Security Industry Association with the FDA, and articles have been written in the Wall Street Journal and Wire Magazines of schools and other institutions being victimized by these vendors. In some cases, devices from China are also using electronic components that have been banned by the US government.
FeverWarn is made by Opteev Technologies, Inc., a subsidiary of Novatec, Inc. The device is manufactured in the US and meets all the criteria established by the Security Industry Association and is FDA compliant in its performance. Novatec and its suppliers have been making industrial machinery and instrumentation since 1965.
FeverWarn is a self-service temperature scanning system. Unlike inexpensive, minimal ambient range handheld devices, another individual does not have to hold the sensor 1-4 inches away from the subject’s forehead—often putting the individual holding the handheld sensor at risk by not meeting acceptable social distancing requirements.
All FeverWarn models offer onboard storage of temperature data. FeverWarn B-series offers optional cloud storage of temperature data.
FeverWarn offers state-of-the-art OPX technology, which extends the ambient range by up to 50% over any other infrared scanner on the market today. This specialized technology makes FeverWarn ideal for poorly temperature-regulated entranceways such as vestibules, which can also be compromised by direct sunlight intrusion.
FeverWarn model FW-250D-OPX offers integration capability with magnetic doors, kiosks, gates, employee card systems, and more.
FeverWarn is a patent-pending system developed by Opteev Technologies, Inc. and its partners Novatec, Inc., a US manufacturer with more than 50 years of experience in industrial equipment, and Prophecy Sensorlytics LLC, a leading IoT company. The following are the unique features of FeverWarn when compared to other products:
It possesses proprietary OPX technology which consists of advanced sensor technology combined with artificial intelligence software. OPX technology provides superior accuracy in each and every scan by ensuring external ambient conditions do not affect the temperature reading.
It is easy to install at doorways, entrances, and employee check-in systems, etc.
Alarm and statistics can be sent to the cloud. Deployers can receive alerts with a timestamp via SMS text messages or emails.
It is calibrated using the human body to maintain calibration easily.
The FeverWarn FW-250D-OPX can be integrated with automated doors via USB output and is offered with Modbus and UART. The FW-250D-OPX model also allows its alarms and other statistics to be available over REST API to integrate with any existing ERP systems.
Traditional non-contact thermometers have suffered from high inaccuracy due to warm or cold ambient conditions and the radiation from hot and cold air molecules. These traditional non-contact devices are notorious for providing inaccurate readings. In a recent Walter Reed presentation, Dr Fauci cited a trip to the White House on a hot weather work day when his temperature was registered by a handheld non-contact thermometer at 103°F outside of the White House, 97.4°F in an air-conditioned car, and then 93°F at another facility. That’s a 10 degree variation in a few hours! This is why almost all non-contact thermometers are only rated to work in 70°- 94° environments. Operating these handheld units outside of this temperature bandwidth will result in inaccurate readings and could lead to an outbreak in your building.
FeverWarn’s new OPX Technology development has been implemented on all FeverWarn models extending the ambient range by up to 50% (from around 40-104°F in actual testing). This proprietary patent-pending technology consists of advanced spatial geometry sensors combined with artificial intelligence software to filter out the effects of cold or warm weather and problems with sunlight.
FeverWarn is the only temperature sensing system to feature this new OPX technology. Unlike any other non-contact thermometer or temperature scanner on the market, FeverWarn is able to provide ultra-high accuracy in environments as cold as 40° all the way up to as hot as 104°, rendering other handheld scanners obsolete.
No matter what happens in the future with many virus variants and vaccine boosters, most employers and employees, as well as teachers and students, now recognize that keeping sick people from any workplace or inside group exposure is just plain good common sense. No matter what virus or bacteria is involved, why would you want anyone with a high temperature in your workplace, school, or waiting room?
Ongoing concern about employee and visitor wellbeing is the new byproduct of the pandemic era, no matter what happens next. Employers do not want to have sick people in their workplace or indoor areas. Employees want to be assured that there are no sick people in the environment as they return to work.
The screening of people with temperatures, no matter if viral or bacterial, is even more crucial as we recognize that most buildings do not have adequate air exchange systems and that inside space with a high-temperature individual can easily result in others getting sick and preventing high productivity and good health.
Employers show they care by using FeverWarn; in turn, employees recognize that FeverWarn is a sign that their employers care about their wellbeing. Employees realize that the screening of visitors keeps them safer as well.
Screening for employee health to keep sick people home is the new standard in building safety and employee wellbeing.
The system includes a bracket for the easy mounting of one infrared, touchless temperature sensor to be installed in either a fixture or entryways so that infrared radiations from a human body can be measured for elevated temperatures.
The OPX spatial geometry sensors included with all FeverWarn OPX Series models collect the infrared radiation in its field of view. Then the infrared radiation energy is converted into corresponding electrical signals when converging on the photoelectric detector.
Optional accessories include floor stands, desk stands, and battery packs.
Yes, the FeverWarn FW-250D-OPX model comes standard with integration capabilities offering a relay signal to integrate with automatic openings. FeverWarn FW-250D-OPX sends an ON/OFF relay based on a go/no go temperature via USB. A customer can purchase an appropriate USB relay converter for their relay system to automate door operation. FeverWarn 1100 models do not include integration capabilities.
Current FeverWarn products are not weatherproof or water resistant. Like most electronic products that are not weatherproof, they can still be used outside with the right precautions and protections. FeverWarn scanners are portable with our optional FeverWarn battery pack, making it easy to take FeverWarn wherever you need it, from the bus line to the breezeway, or from a building’s entrance to a hallway; however, FeverWarn should not be used in outdoor situations where there is a chance of it getting wet or damp from inclement weather or extreme humidity. Think of it like a non-weatherproof speaker system. Could you enjoy those speakers outdoors on a nice day? Yes, but you wouldn’t want to leave it outside at night and you certainly want to take it indoors if there is any chance of inclement weather. For that reason, we suggest only using FeverWarn outdoors for a short period of time in ideal weather conditions and to keep it under a roofed area or cabana during that period just in case.
The FeverWarn Crystalball Cloud is built on the Microsoft® Azure Cloud platform. The servers are in Virginia, USA.
FeverWarn B-series models have access to the optional Crystalball Cloud service.
The Crystalball Cloud allows for easy to access compliance reports, real-time fever alerts via text and/or email, as well as real-time visualization of temperature scans. It also software features will be automatically updated rather than manually downloading and pushing to the device.
Many FeverWarn users store their anonymous temperature scanning information directly on the FeverWarn Crystalball Cloud (managed by Microsoft® Azure). The advantages of this are that data can be seen anywhere, anytime, as opposed to the mobile app where data can only be seen when close to the device.
