Taking the Temperature on Thermal Imaging
By: Steve Morandi,
VP of Product Management
Let’s take a moment and ponder several numbers…. 15,300, 775 and 2,581,230.
Bold enough to imagine the next number in the sequence?
Careful – these are not prime numbers; not the number of stars in some distant galaxy; they have no higher order relation to each other, nor a discernable pattern. Given the lack of information, venturing a guess at a fourth number in the sequence is a fool’s errand.
In fact, what they do represent are the number of 2019 non-suicide gun-related deaths in the United States; the number of 2003 SARS global deaths, and the YTD number of COVID-19 cases in the United States. All unpredictable, crossing time/global /threat boundaries, and somewhat random. Even with the daily non-stop drum-beat coverage of COVID-19 cases, hospitalizations and deaths, the “experts” are no closer to estimating what the final tally will be for 2020 US cases or the economic impact it will impart.
The broader observation is that we live in a world of uncertainty with a variety of threat vectors. Some are known, while others are lurking behind a future unsuspecting corner.
The Coronavirus caught the world off-guard and it continues to affect every part of our lives. After months of the most substantially reduced business, education and social activities we’ve ever seen, we’re reemerging into a ‘new normal’, or quite possibly, the ‘now normal’.
Against this backdrop, safety is the top focus. For individuals and organizations alike, risk of exposure to the virus and defending against its spread are paramount. We’re all trying to come up with game plans and calling line of scrimmage audibles as we go. Recently, we hosted Evolv Advisor and Crisis Response Expert, Juliette Kayyem, in our “Adaptive Recovery” Webinar, where she provided guidance and insight as she walked through her Adaptive Recovery Framework to discuss reimagining recreation, education and the workplace.
Evolv has always been about keeping people safe as they live, work, learn and play. Our touchless security screening systems have redefined what’s required in modern physical security and have protected more than 50M people from guns, knives and bombs.
Today, COVID-19 is the biggest threat on virtually everyone’s mind. It “weaponizes” people. By doing so, it’s changing the very fabric of our society and challenging our social norms.
Perhaps unsurprisingly, there is a surge of interest for thermal imaging as a front line of defense. Screening people for elevated temperature to identify potential carriers of the virus seems like one of several logical steps. There is a range of technologies and products available from multiple providers. In fact, I recently heard a reference to more than 150. Suffice to say, there is no shortage from which to pick.
Given the proliferation of options and “entrepreneurs”, it is critical to understand what thermal imaging can provide…and what it can’t. It can be a valuable component to a multi-layer security screening approach, but it’s not a silver bullet. Here are some insights to help your organization as you consider deploying thermal imaging.
- Almost all solutions are measuring a visitor’s skin temperature as a proxy for the person’s body temperature. It is a preliminary screening and should be paired with a more comprehensive health screening station (venue defined) for “alerted” individuals.
- It is important to vet the claims about accuracy and detection capability.
- Familiarize yourself with the comprehensive guidelines issued by the FDA this year to ensure solution alignment.
Later this month, Evolv TempCheck™, part of our new optional thermal imaging package for Evolv Express™, will become generally available. You might ask “Why Evolv?”
This optional package represents another proof point for our ability to quickly and easily provide customers with new capabilities to address the threats we face today and to move quickly to address those we’ll face in the future. It creates an enduring product, one that is flexible enough to grow with you over time, instead of becoming obsolete, where you tuck it away in a corner or closet.
Here is a sneak peak of what you can expect…a physically integrated capability that’s a powerful add-on option to the Evolv Express touchless security screening system. One that’s mindfully integrated into the Evolv Express concept-of-operations (conop) to enhance the touchless visitor experience while optimizing venue footprint requirements and security staff resources.
Each visitor can be screened for elevated skin temperature in an average of 2-3 seconds, followed by immediate, frictionless, and touchless weapons screening. With this optional add-on package, venues are now provided an integrated health and weapons screening touchless conop, and the ability to screen 800-1300 people per hour per dual-lane Express, optimizing facility space and resources.
As noted earlier in this blog, the threat vectors are varied, complex and unpredictable. Evolv’s unique multi-sensor, software-centric platform allows us to add additional sensors and AI-driven applications to respond to this expanding threat landscape and assist our customers as their world and operational requirements change.

In late May, Evolv hosted the “Adaptive Recovery” Webinar with Juliette Kayyem, former Assistant Secretary at the Department of Homeland Security. Juliette spoke about crisis management using her Adaptive Recovery Framework for managing an organization’s reopening and recovery across a variety of different sectors of the economy. At that time, planning was underway for schools to eventually reopen and for workplaces and recreation entities to reopen. This blog post has been excerpted from Juliette’s discussion on the webinar and expanded on.

A month has now gone by, and while many organizations have put their plans into action, others continue to prepare for their reopening in the coming weeks and months. Many states have begun to lighten their restrictions, allowing restaurants, businesses and stores to reopen. And, even some theme parks and aquariums are opening their doors. Regardless of where you are on your reopening timeline, Juliette’s sage advice is worthy of embrace:
- Go slow, have a plan AND a back-up plan
- Embrace the “now normal” and use all available tools and resources
- When integrating technology, opt for ones with longevity and flexibility
Here’s What We Learned for the Recreation Sector.
The bad news is while the virus is new, crisis management isn’t. The good news is we have expertise and experience in crisis management. This pandemic is nothing if not a crisis.
First things first …. don’t think about opening up as a moment in time or a threshold to cross; think of it as an organic process. Here’s why. In times of crises, like hurricanes or tornadoes, there is a moment of “boom” and the enemy is gone, response and recovery begin – a specific moment or crossing a threshold if you will. In this crisis, the enemy isn’t gone and in fact and unfortunately, will be around for a while – – this is a “rolling boom” hence the need to continually adapt.
Key Questions to Ask Yourself.
As security, operations and guest experience managers, the reality is we’ll have to continue to adapt to the virus in real-time and over time. That means planning, re-planning, embracing new governmental requirements, responding to new outbreaks and eventually, hopefully, administering a vaccine.
But the common thread through the multitude of plans is risk reduction, a balancing act based on three elements:
- What’s the intensity of the interaction? Can I limit the number of people?
- Can I control the number of interactions? Is it possible to social distance? Am I able to enforce crowd control?
- What is my ability to mitigate? Can the cleaning protocols be modified? Is detection possible? Do I have access to testing capabilities?
Where Does this Leave Us?
Two things we know for certain: social distancing and touchless security/venue features will allow you to come back more quickly and ensure patron safety.
Specifically, for entertainment and recreation entities, here are a number of areas you can focus on as you plan your reopening, or continue to adjust over time. We’ve outlined changes based on your customer’s journey, from the time the individual approaches your venue or facility until they are inside and enjoying themselves!
Communication & Planning Prior to Arrival
Planning their Visit
One of the best ways to provide peace of mind, entice visitors to your venue and ensure they are well informed is by providing clear communication to them in advance. Use your website, create a video, use social media accounts, e-newsletters and email reminders to communicate the importance you have put on the cleanliness of the venue and the care around staff interaction with guests, as well as the considerations you ask of your guests to adhere to guidelines for the safety of all. And, don’t forget your employees. Consider implementing an employee health survey they take before arrival to work.
Go Mobile. When possible, implement paperless ticketing utilizing an app or email to provide patrons/guests with a scannable QR code or barcode for entry. A significant reduction in the use of paper tickets will eliminate surfaces from which germs can be spread. Don’t forget, additional benefits to implementing paperless ticketing is guests will no longer forget their tickets at home or have to stand in will-call lines. And, there is less fear of stolen tickets.
Stagger Arrival Times
If possible, a great way to help avoid crowds in the parking lot, on the trams or buses to the park entrances and at the park or venue front gates is to stagger arrival times. Just like the airlines provide boarding zones, and golf courses are now staggering tee times, you could implement entrance times or zones in advance to help keep the flow moving at a steady pace instead of bottlenecking anywhere on premise.
Contactless Guest Screening at Arrival
Ensuring the safety and health of guests and staff has required a number of measures to be put in place. These include asking patrons and guests to assess the risk they have coronavirus and could infect others, screening for elevated body temperature, and screening to detect and prevent weapons from entering.
How might you institute temperature screening to mitigate risk of allowing someone with a high fever with potential contagions into your venue? Will you use handheld temperature reading devices or larger touchless ones? Who will be overseeing the thermal read-outs and making the judgement calls on whether the numbers are accurate? Do you need to hire dedicated medical staff to manage this function?
What will you do when someone is found with an elevated temperature? It will be extremely important to have a policy and procedure in place and have properly trained your staff on how to react. You’ll also want to consider including language in your Venue Guidelines document or website that addresses what happens if a person is found with an elevated temperature, especially as it pertains to refunds and what to do with the rest of their party.
Touchless Weapons Screening
Many of you already had weapons screening in place to safeguard your venue, but prior to COVID-19 did they create long lines and force contact between guards and fans or guests? We have now entered a new phase of venue security where both weapons and health screening is important, meaning the systems used “yesterday” such as traditional metal detectors, pat downs and manual bag checks will no longer be the systems capable of screening for threats of “today” or “tomorrow”.
Consider a touchless security screening solution that can screen people and their belongings in real-time as they walk through your doors without long lines, and without invasive search procedures. You should look to technology that will grow with you over time, adapting to new threats and allowing you to add-on additional features and sensors for cost savings and increased security in the future.
Social Distancing & Hygiene Once Inside
Being able to boast that you sold out every seat will be a thing of the past for a while. It’s time to get creative. What can you do to change your seating structure to reduce the intensity of interaction and limit number of interactions? Can you sell every other or every third ticket? Do you have sections for parties of 6 to make it easier for groups to stick together without having to readjust your entire new seating chart? There are plenty of diagrams you can consider and put in place depending on attendance levels and venue layout.
If you’re an outdoor venue with “lawn seating”, you might want to put up ropes or mark off seats with tape or chalk to help enforce distancing.
For theme parks and attractions, it will be easy to manage seating positions of park guests on rides by training staff to control the seating placement, and the IAAPA has identified some guidelines to help you think about capacities that allow for physical distancing.
Across the country restaurants have had to reinvent themselves. In many states, eating in a restaurant is still prohibited, so restaurants have had to think outside the box on how to serve customers and keep revenue flowing. Some have opened up outdoor dining sections taking over parking lots, lawns, city streets and sidewalks, and many now offer take-out or delivery to ensure people can have their favorite gourmet food but eat in the comfort of their own home. For some restaurants, that means they are now accepting credit cards, PayPal or Venmo for the first time ever; some are offering a contactless self-ordering system and table service; others are having patrons scan a QR code for their food or drinks menu, make reservations or even connect to a restaurants payment tool. And, once self-serve, salad bars in restaurants and grocery stores are now open again with one distinct change, employees are now dishing out the patrons’ selections.
You can use some or all of these lessons learned from restaurants across the country to update your concession stands. Start with how to limit or erase lines. Do you allow certain sections to go to certain concession stands? Do you add more pop-up food stations to create more places to purchase food? Or better yet, do you launch/create an app for virtual queuing where the fan or guest selects the concession stand they’d like to purchase from and add themselves to that line, when it’s their turn, they are signaled to walk over to the concession? Or best of all, why not use an app in combination with waiters/waitresses; the fan or park guest downloads the app, orders their food and pays online, a waiter/waitress brings the food right to their seat.
Next, make sure you go touchless. Bring those condiment carts behind the counter and have your staff serve them. And, don’t forget about menus. If you usually hand out laminated menus reused with each guest, it’s time to throw them out unless you plan to sanitize them after every use. Although some venues have opted to print one-time-use paper menus, the cost to you and the environment will add up. Think about implementing an app or QR codes for ordering.
Hygiene Stations & Touchless Amenities
Keeping areas clean is paramount to stopping the spread of germs. Have you asked yourself how often railings, door handles, counters and bathrooms should be cleaned? Do you need to hire additional janitorial staff to ensure these areas are maintained? Do you have pop-up handwashing and/or hand-sanitizing stations throughout your venue or park? Do you remove all drinking fountains and install water bottle refill stations that are managed by staff and sanitized between each use?
What about your faucets, toilets and paper towel dispensers…are they automatic, or do they involve the turning of a handle? While some of these would be costly renovations after already losing revenue these last few months, you can choose a variety of ways to make your venue or facility cleaner and keep the presence and spread of germs to a bare minimum.
The Moral of this Story…
No matter how much you prepare in advance of reopening, one thing is for certain – you will need to watch, measure, evaluate and be ready to make adjustments as necessary.
Adhere to your local government guidelines and embrace the physical and technical adaptations you can make, to build confidence among your returning visitors, patrons and fans and ensure a safe and fun time for all.

Interview: Evolv powers Six Flags’ new touch-less way to go through theme park security
Imagine going through theme park security without having to open all your bags and allowing a security guard to look through your things, or not even having to put your bags into an x-ray machine. That may be the case soon at some Six Flags parks.
As attractions begin reopening after their coronavirus closures, theme parks are reevaluating the security screenings their guests go through in light of social distancing measures, and Anil Chitkara’s company, Evolv Technology, has introduced an innovative touch-free system Six Flags recently featured in a video highlighting their parks’ new safety procedures.
Ever since 9/11, theme parks have implemented various types of security screenings to ensure that guests don’t enter with weapons or other prohibited items. The Walt Disney World and Disneyland resorts use a combination of manual bag inspections and walk-through metal detectors, while Universal resorts employ automated bag-screening machines and walk-through metal detectors. However, in announcing their reopening plans, Six Flags has released the following video depicting the use of the Evolv Express security system in their parks, which permits guests and their belongings to be inspected while walking through without removing or opening their bags at all:
The new bag screening system depicted in Six Flags’ video comes from Evolv Technology, which was co-founded by Anil Chitkara. Six Flags will only confirm that the chain has ordered 37 Evolv Express units, but is not sharing publicly at this time at which parks (in addition to Frontier City) they’ll be used at, or how many units per park. Chitkara himself was unable to confirm or provide any specific details about his company’s involvement with Six Flags (a standard contractual limitation in the security industry). However, he did provide us this exclusive interview about how his team is helping to keep guests both safe and happy in the age of COVID-19. (Note: this interview has been edited for space and clarity.)
How did Evolv Technologies get started?
We started the company about seven years ago, myself and my co-founder, named Mike Ellenbogen. Mike has been in the physical security industry for 20 years after Pan Am 103 … My background is more sort of business and technology. And we’d known each other for 15 years at that point.
I had sold the company I was at, Mike sold the company that he was at, and we were trying to figure out what to do next. There were two pieces of motivation: the Boston Marathon bombing, and 9/11. In the case of 9/11, my college roommate and good friend was in the north tower; had just gotten married, had a kid and unfortunately, he was part of Cantor Fitzgerald [headquarters], which was tragic.
In the case of the marathon, my wife is a marathoner. She had run that marathon. I had my three young kids at the finish line. She finished about 45 minutes before the first bomb went off, got in the car and came home … and then all of the news happened. A good friend of ours was there, actually, he got hit with the second bomb and has fragmentation.
It really caused me to think about, what do I want to do next? And how do I want to spend the next 10 to 20 years? I had done a lot with technology to solve business problems. Mike had done a lot to bring innovative technology to physical security. And we went out and talked to lots of people about how they were trying to keep their venue safe.
I thought about my kids. I don’t want them to have to live a life where it is airport-style screening everywhere they go. I want them to be able to live as freely as possible, but also as safely as possible. And that was my personal motivation around starting a company.
Where is your technology currently in use?
At the end of 2017, we started deploying technology, so it’s been deployed and screening people since the end of 2017. We’ve screened well over 50 million people since it’s been deployed; it’s probably closer to 60 million people now. And our customers have used the technology to find thousands of weapons. The types of places where it’s deployed are largely commercial venues, so those have been performing arts centers, sporting stadiums, museums, and tourist locations. They’ve largely been places where they hadn’t used walk-through metal detectors up to that point; they’d been trying them, but they just weren’t doing the trick. They basically were too invasive relative to the visitors that were coming in.
About a year ago, we launched the second product, which is the Evolv Express product [which is what is featured in Six Flags’ video]. We’ve screened millions of people with that product. There were two very large events we did last fall screening with Express. One of them was a week long conference in San Francisco where we screened about 500,000 people, and then there was a second conference we did a month later where we screened about 400,000 people. So there’s been some very large-scale, high volume deployments that have been used the system. There are other applications where people are screening it using it for visitors on a daily basis.
We haven’t yet used it in a theme park environment. We’ve used it in large-scale events, and we’ve used them in some sporting events in some performing arts and entertainment events. But not a theme park event up to now.
What’s the hourly guest capacity and staffing requirement of the Evolv Express?
One unit of Express has two lanes. Each of those lanes could do 1,800 guests an hour, or 3,600 for that combined system. That compares to a walk through metal detector where they’re doing “take things out, check the body, check the bags,” those tend to be about 250 to 300, maybe 350 people per hour. So this is about 10 times the speed of a traditional approach.
If we look at the walk-through metal detector, let’s say you need 10 units. They tend to have two and a half people per unit; they have a front and a back and a supervisor. For us, you tend to have between four and six people per unit, so the staffing is significantly reduced.
The turnover in the security guard industry in the U.S. is 300% or three times a year, the entire industry. Therefore, training and getting skilled guards is a challenge, so we have automated some of the key tasks [and] provided a level of automation that assists the guard, so that they can be very targeted in their search.
What are the advantages to Evolv Express over traditional bag screening methods in a COVID-19 reopening environment?
Ninety days ago, we used to talk about 3,600 people an hour coming through; today, we talk about a touchless contact screening process. If I’m going through those 42-inch-wide lanes, without taking anything off and going right through and the alarm rate is extremely low, then I keep going; thousands of people are going through never being touched by a security guard. One benefit is the proximity of guard-to-visitor is lower, because they walk right through. A second benefit is the speed enables people to go through quickly without lines building up, so are eliminating visitor-to-visitor proximity as you’re waiting in line to go through security. And then anybody that’s looking at bags manually is touching every bag; people are trying to figure out how can I have less touch, but fundamentally, you’ve got to look in the bag when you’re doing a manual process.
How does Evolv Express improve the overall guest experience?
There’s so much work and effort that’s put in around the visitor experience, but then the security experience just grinds things to a halt. There is excitement, you get there, you want to get in, you want to participate or listen or enjoy the entertainment, and then grinding to a halt because I’ve got to stop, I’ve got to put my bag down, I’ve got to take everything out of my pockets. That’s we’re trying to fundamentally change: that visitor experience. That’s essentially one of the key principles of the technology we’ve developed.
Have there been studies demonstrating your technology’s detection rate compared to the more traditional methods?
We’ve done a number of studies with both government and commercial organizations, and a number of large organizations will do the testing themselves. They’ll do lab-based testing: we’ll take a system and run a bunch of threats through and a bunch of nuisance alarm items that they’ll read. And they’ll actually put threats on individuals and have them go through the system in operation. We’ve done that extensively; we can’t share specific customers or specific examples of what’s been done, but that’s been done a number of times in the U.S. and Europe. And what they had found is that the detection rate is a combination of the technology, plus the people operating it, plus the processing protocols … The breakdown oftentimes comes in the guards or the protocols relative to that overall system, so what’s been told to us is the effectiveness of the overall system has been much higher with our technology as part of an overall system than with the traditional technology.
How is the Evolv Express system priced?
We don’t publicly share actual pricing levels. We have a subscription model … a per month fee, not “buy it and you own it forever.” We include improvements, upgrades, service, and everything all combined into that one monthly price. So the pricing model is something we believe is pretty unique in the industry.
What is your current outlook as attractions reopen after the pandemic quarantine?
Everybody sort of hunkered down when COVID hit right. There was a lot of “how am I going to respond to this?” Over the last four weeks, we’ve had a significant amount of inquiries from organizations as they plan their reopening. And many of these organizations have used the “mag and bag,” (the walk through a metal detector and bag) approach in the past and they just don’t believe that’s the right way to go to do it going forward. What’s changed is they’re trying to balance the public health threat and the public safety threat, and do something that considers both of those.
It’s going to be different going forward. It needs to be lower touch, it needs to be cognizant of the public health risks, as well as the public safety risks. And so they’re looking to our technology to be able to help them enable that.
