The 12 Things You Need To KnowBeore Buying an Inrared Camera

Buying an inrared camera is dierent or all people. For some, cost will

play a more dominant position whereas or others, certain key eatures

or the desire to advance ones career through certied training might be

more important. Most, however, want a high level o quality and value.

Still more just dont want to make the wrong choice and end up with a

new thermal imager that is heavy or hard to use.

At FLIR, we want you to succeed. Back in the mid-1960s, we brought the

rst commercial inrared camera to market. We invented this market. So

rest assured this booklet will help you pick the best inrared camera!

Having been the worlds largest inrared camera manuacturer and having

operated the worlds largest training organization the Inrared TrainingCenter or ITC weve learned a thing or two about inrared. Here are 12

Things to help you too.

Readers please note: we use the term inrared camera, however we

could have just as well used the term thermal imager. They are one in

the same, interchangeable terms.

I at any time you have a question on what is presented below, or you

have questions on what inrared camera is best or you, please give us a

call at 1 800 GO INFRARED (1 800 464 6372).


4/23

Point #1: Buy an inrared camera that deliversaccurate, repeatable results.

This may sound like a no-brainer, but i ever the phrase caveat emptor i.e. let the buyer beware it is here!

Imagine i you bought a calculator and you noticed that sometimes you

added two-plus-two but when you hit the equals sign it didnt add up

to our! Even worse, imagine that when you bought this calculator you

rather assumed that it would work, and like most people you didnt ques-

tion its accuracy. So, you went about your business and there were no

problems. But, then one day you got a letter in the mail that your check-

ing account was severely overdrawn, and you went back to crunch all the

numbers and, while you were doing this, you noticed that the calculator

made an error once in awhile.

You wouldnt be happy, to say the least. Whats more, depending upon

the errors made you could be just a little overdrawn or you could be in

serious trouble.

Said dierently, a basic requirement o your inrared camera is to produce

accurate and repeatable results just like a calculator.

What are some standard metrics or you to think about when thinking o

buying an inrared camera?

Well, ater 40 years in the business, FLIR has maintained a solid, consistent

accuracy standard that never waivers. Its the industry standard: 2% or

3.6 F, whichever is greater.

Its read as plus or minus two percent or 3.6 degrees Fahrenheit, which-

ever is greater.

So i you are shopping or an inrared camera, and you learn that theaccuracy spec is plus or minus 5% or something higher than 3.6 F, then

2


5/23

you should stop right there and not even consider buying it.

Why? Because an inrared camera that could be 5% inaccurate could

just like the calculator in the example get you into serious trouble. Your

images and temperature measurements will be wrong. Another analogy

is like saying you almost got the phone number correct, you were only

o by one digit. Well guess what? Its completely wrong.

Remember above how we said that a basic requirement o your inrared

camera is to produce accurate and repeatable results? Well, there are two

other requirements to making this work over and over again.

In order to produce accurate and repeatable results, there needs to beinputs in your camera or both emissivity and refected temperature,

as indicated with the red arrows in the picture below.

I you are concerned that you dont know what emissivity or refected

temperature mean, well thats ok. This is industry jargon and i you were

to buy an inrared camera, you would amiliarize yoursel with these terms.

Theres more on training later on, so dont worry about this right now.

3


6/23

Just know that, again like in our example, you wouldnt buy a calculator

that is missing the plus (+) sign button even i had an attractive selling price.

I a manuacturer is trying to sell you an inrared camera that doesnt havea place onscreen or you to input both emissivity and refected tempera-

ture values then youre buying a calculator thats missing a button!

Point #2: Buy an inrared camera with highdetector resolution/image quality.

Just like buying a digital camera, the more pixels, the better the

resolution, and the sharper the thermal image.

But to create another example rom our everyday lives, lets say you just

bought a High Denition TV. Now, lets say that in your local area, the local

cable company doesnt broadcast an HD signal yet.

Now lets say you approach your local cable TV salesperson and say well,

I just bought an HD TV and I just want to hook it up to my regular

(i.e. non-HD) cable jack in my living room. Will that still give me a High

Denition picture on my new TV?

O course the answer is No, it wont work.

It wont work because the regular cable jack isnt broadcasting the

exceedingly high pixel count o High Denition. So, even i he has a TV

capable o displaying High Denition, i theres no High Denition eed, so

to speak, then it just wont work no matter how good the display is.

Maybe the person who sold our riend here the High Denition TV

ocused too heavily on the capabilities o the display itsel the TV. But

maybe he also ignored the act that our riend wouldnt be able to buyany high denition access.

4


7/23

Its the same with inrared cameras.

In our example, lets assume that the eed or the HD cable access is really

the IR detector pixel resolution and the TV itsel is the LCD display.

Again, buyer beware: i a salesperson says, we oer 640 x 480 or 307,200

pixel resolution, the next question rom you should be: Is that Detector

resolution or LCD resolution?

The LCD display resolution may in act be 640 x 480 (read 640 by 480)

or capable o displaying 307,200 pixels (640 multiplied by 480) o image

content. But, i the IR detector pixel resolution the eed as it were isonly 160 x 120 or 19,200 pixels, then it just doesnt matter what the

display resolution is capable o.

Said dierently, you cant get a lower detector resolution to broadcast in

higher denition even i the LCD display has the capability to show more

pixels. Or: you cant make your HD TV work with a regular cable jack!

You should always ask what is the detector resolution, and what is the

detector pixel count? This is really the true resolution o the camera you

are about to buy. I you look at this, then yes, the more [detector] pixels,

the sharper the thermal image.

Point #3: Buy an inrared camera where you canchange the battery yoursel.

This is one o the most important aspects o usability ater you buy your

new inrared camera. Its also one o those items that is hard to process

until ater youve been working with your camera or awhile and you real-

ize what a limitation it is i you cant change your own battery.

Lets think about using a cordless drill in your home. Like many home-

owners, this author will rom time to time remodel a room. In act Ive just

5


8/23

gutted my kitchen. Now, as I think about the job, I say to mysel things

like tomorrow Im going to hang the blue board. Then I think, do I have

enough drywall screws, Ive got my drill, Ive got the material.

My point here is that when you think about your job, you assume certain

things. In this case, I know I wont have a problem doing the job because I

have a good, high quality drill and you know what? Once I get started, my

battery will die and I will pop it out, take another one rom the charging

station and pop it into my drill and, importantly: keep on working.

I think its sae to say or most anyone that nothing is more rustrating to

start working on something and then have to completely stop becausesomething simple just wont work right! I my battery died and I couldnt

change it right then and there I my battery died and I had to plug a

cord into my drill and wait 2 hours or it to recharge, well, then Id go buy a

dierent drill.

The same is true i not more true or inrared cameras. How can it be

more true? Well, i youre using your camera to inspect electrical prob-lems, or to inspect important assets like motors and pumps and produc-

tion lines in a manuacturing acility, and your IR camera loses power, you

could expose yoursel and others to saety concerns particularly in an

electrical substation that hasnt been inspected in awhile. At a minimum,

youre on the clock, so it is most likely costing you or your company

money. Not to mention, youll denitely look like you bought the wrong

IR camera, or worse: that you dont know what youre doing.

Heres the scoop on power management systems or IR cameras:

10/23

Point #4: Buy an inrared camera that outputsstandard JPEG ormat.

This point is short on text to explain, but long on being a clear benetto end-users. Would you buy a computer that wasnt Microsot Word

compatible? O course not. You shouldnt buy an inrared camera that

requires additional sotware in order to convert their proprietary thermal

image ormats into a standard jpeg.

You should demand a demo rom any inrared camera manuacturer so

they can show you both (1) how many keystrokes or clicks it takes to

output an image and (2) outputting a standard JPEG right rom the

camera. Standard JPEG makes it easy to email your images or place

within Microsot Word documents without trouble or rustration!

In the United States, FLIR holds the patent on what is called a ully

radiometric JPEG, which means that all your temperature data stored in

the thermal image on your inrared camera is automatically transerred

to the industry standard JPEG ormat. Said dierently, you get to keep allyour temperature data stored in the JPEG even when you email it to a

colleague, supervisor, customer, etc.

The analogy here is, what i you bought a new phone with an embedded

camera in it, and that camera took great color pictures, but when you

went to email them they only transmitted black and white versions o

your pictures! In eect, it would strip away the color, strip away much othe value o your phones camera. The same is true with inrared cameras.

You buy an inrared camera or the sharp thermal imaging and or the

temperature measurement data in those images. Ater all, thats why they

call it a thermal imager. I you took thermal images but then, when you

send them over email, it strips out all the temperature data, its like our

camera phone that only transmits in black and white!

Again, ask or a demo to see what the level o diculty is to download aJPEG. Be sure to inquire i those JPEGs are standard or rst have to run

8


11/23

through the manuacturers proprietary or conversion sotware. Finally,

you should really decide whether or not you want the ability to send ully

radiometric JPEGs over email.

Point #5: Buy a lightweight, ergonomicinrared camera.

Material sciences, manuacturing robotics, and other key engineering

actors will literally weigh on your decision o what inrared camera to

purchase.

Weight, pure and simple, is a concern. A camera that weighs even just a

pound or two more than another will start to cause back and arm strain

within 20 minutes. One need look no urther than all sorts o products we

use everyday, rom vacuum cleaners to that really neat new lawn trimmer

we see on the TV inomercials. Lightweight is key, especially i you will use

the camera requently or or extended periods.

Also, the small, lighter and more ergonomic the inrared camera, the more

likely you will be able to hang it o your work belt in a holster to give you

hands-ree control whenever you need it. Be careul here, however,

because a manuacturer can make a holster any size. Most toolbox

inrared cameras today should weigh in at under 2 lbs and eel veryeasy-to-grasp in your hand.

9


12/23

The inrared cameras physical interace its buttons are critical to its

ease-o-use. While it may seem counter-intuitive, it is oten the case that

an extra button or keypad will actually make it easier to use your inrared

camera, as opposed to trying to do the same unctions with less buttons.Some inrared cameras even have integrated onscreen (even touch-

screen) keypads or sketch-with-a-stylus unctionality. These may cost a

bit more, but the added unctionality is signicant and should be seri-

ously considered.

The on-camera buttons should also be very comortable to use, but more

importantly, intuitive to understanding what unction each button deliv-

ers. In some instances, manuacturers can also make inrared cameras orthe military, where the buttons must be literally certied or battleeld

conditions. FLIR has done a good job transerring the ease-o-use and

durability it puts into its military-grade inrared cameras into its

commercial inrared cameras. In addition to improving ease-o-use, it

can also be more relevant in harsh manuacturing or extreme heat/cold

weather environments.

Its critical that you get a demo and walk through the various day-to-day

activities you will perorm: saving an image, downloading to your PC,

creating a simple report. Why? Because until you see rsthand how many

clicks and steps it will take you with any given inrared camera/sotware

package, you will never know i the system will work well or you. Some

inrared cameras require multiple steps to do a simple task, and some

simple operations can be buried deep within some dicult-to-use menus.

Get a demo on the basic unctions or you could be signicantlyincreasing the day to day diculty not to mention rustration you will

run into ater youve bought your inrared camera.

Point #6: Buy an inrared camera that incorporates

a mega pixel visual camera with a built-in illumi-nator lamp to help clearly document your work.

10


13/23

Inrared cameras see in total darkness but visual cameras, as we all know,

require well lighted conditions and high resolution to generate clear,sharp pictures.

Would you buy a digital camera to take amily pictures without a fash?

O course not! Why? Because you know youre going to run into

situations where night is approaching, or the room just isnt well lit.

I youre in a commercial environment, youre going to run into these

situations more, not less.

These pictures say a thousand words. Its the same target.

The image on the right is taken with an inrared camera with, essentially,

some headlights mounted on it the target illuminator, as many

thermographers would call it.

14/23

Point #7: Buy an inrared camera with a built-inlaser pointer.

Saety, convenience and ease-o-use are all good reasons to buy an inraredcamera with a built-in laser pointer. These tend to be available on all

cameras, except or the most basic, entry level models.

Saety is always the best reason to spend a little more on the right tool.

I you shouldnt be touching the target youre looking at with an inrared

camera say or example, an electrical box, motor, pump or something

when viewed rom a ladder then the laser pointer helps you in two

important ways.

The laser pointer keeps your hand ree and clear rom danger while

allowing you to point to the area o concern to a co-worker (or supervisor

or customer) standing nearby. It allows more than one person the ability

to xate on the problem in ront o them.

Secondly, the laser pointer helps you orient yoursel in relation to thetarget. This is particularly true i you are standing more than 10 away

rom the target. It answers your internal question: now, what is the camera

looking at specically? The laser pointer allows you to see precisely

where the inrared cameras lens is ocused. Its also ideal in gaining more

orientation in dark environments, even i youre standing closer to the target.

There are many analogies here, but to go back to the consumer worldits like having a dishwasher or microwave. Can you imagine not having

these tools in your kitchen. I you speak with thermographers who have

built-in laser pointers on their inrared cameras, they will tell you they

couldnt imagine working without it. Enough said.

12


15/23

Point #8: Buy an inrared camera with sotwareupgrade potential.

Today, most inrared cameras come with ree sotware to help you analyzeyour images and create reports. By all accounts, they are a helpul tool

made all the more necessary by both the corporate need to document

ndings, but also increasingly to use thermal images and reports to

substantiate or trigger insurance claims, while the reports themselves are

oten sold to commercial and consumer customers or a wide range o

inspections: energy audits, electrical inspections, gas detection surveys,

building envelope analyses and predictive maintenance surveys.

While these entry-level reeware programs are helpul and useul, many

individuals quickly nd that they need more sotware unctions. Whats

important to note here is you dont want to buy a camera and then, ater

a ew months o using it, decide that youre now ready to do more but

only then be limited because there is no upgrade path.

Buy your second boat rst!

Why do I say that? Well, to anyone who has ever bought a boat this is a

common theme. The reason is simple. To someone new to boating, it is

easy to think Ill buy a small boat without all those built-in electronics.

I just want to get started. Its going to take some time or me to get

accustomed to all this anyways.

Our riend here, lets call him Joe, has a good point. The problem is Joe

is going to get his boat and ater a ew weeks, hes going to be pretty

comortable with using it. A ew more weeks ater that, Joes going to

have it down pat. A ew weeks ater that Joes going to be bored with his

purchase and rustrated because he cant really upgrade his boat without

spending a lot o money; enough money that makes him think he made

the wrong purchase decision and now he has to try to sell his now-used

boat i he wants to go out and buy a new boat with the eatures andunctionality he now wants.

13


16/23

Joes not alone. Weve all been there.

There are a couple o points here that you really should think about.

First, you should at least get a demo or the inrared camera thats onelevel above what youre currently thinking about buying. O course it

will cost more money, but dont just skip over the thought process based

solely on price. Know what eatures and unctions youre giving up i

you buy the less costly model. Even i you end up buying that less costly,

lower-end model you will know what youre missing and this, in and o

itsel, is an education in inrared. So yes, you should consider buying your

second inrared camera rst.

But, more to our original point, i you buy the less expensive model and

you know that, like a boat, you cant upgrade the hull or the chassis.

But, unlike a boat, an inrared cameras hull or chassis is really related to

the undamental quality o engineering design and manuacture, which

means you can upgrade its unctionality quite a bit with the purchase o

some new add-on sotware.

We dont have time and space here to go through all the things you can

do with this new sotware, and this table below doesnt do justice to all

the great things youd be able to do, but here it is or reerence. When

you get a demo, you can always ask to see the sotware upgrade and its

eatures and unctionality. Ok, heres the chart:

ITEM DESCRIPTION FREE SOFTWARE UPGRADED SOFTWARE

Word Document Yes Yes

Image manipulation in word No Yes

Instant report generation No Yes

Movable PIP/Fusion No Yes

Report Customization No Yes

Trending No Yes

Archiving No Yes

Formulas No Yes

Arrow Tool No Yes

Digital Zoom No Yes

17/23

Point #9: Buy an inrared camera with enhancedimage usion capabilities.

Theres been a lot o buzz about usion capabilities with inrared cameras.Our thinking on usion is i it doesnt oer you more than just putting a

xed Picture-in-Picture (PiP) thermal overlay box over your visible image,

then it may be more useul not to have it at all.

Instead, be sure that that you can do basic image manipulation, such as

being able to move the thermal box around, or even make it bigger or

smaller. More advanced usion capabilities allow you to stretch and resize

the thermal Pip using a stylus pen right onscreen, allowing you to

customize your usion to the exact target your looking at. This can be

ideal or analyzing the problem, and it also just makes your inrared pop!

For those who need to present documentation to supervisors or customers,

this enhanced usion capability will really make a avorable impact.

At its most advanced level, some inrared cameras allow you to dial-in

a combination o visible and thermal imaging into one composite image.This can produce exceptional results and exceeding smart reports.

Rule o thumb: i youre looking at an inrared camera with built-in usion

capabilities, be sure you can move and resize the thermal box in the

middle o the LCD display.

Its like a pair o biocal eyeglasses. The top hal lets you see clearly araway, while the bottom hal is useul or close-up reading. You resize by

looking up or looking down and they work great. But imagine i they put

the close-up lens right in the middle o a normal pair o eyeglasses! And

everywhere you look, theres this box in the middle and it gets in the way

o everything you view. It wouldnt be useul. It would likely become

annoying and you would want to turn it o.

15


18/23

Thats why we say i the inrared camera youre looking at has a xed box

showing you a thermal overlay to your visual image and you cant move

or resize that box, then dont buy it. You can easily do better.

FLIR has created a great video, and it really shows clearly what this is all

about. You can view it at www.goinrared.com/usion.

Point #10: Buy an inrared camera with a widetemperature range.

Heres an easy one. When you buy an inrared camera, be sure that the

temperature range it operates in is sucient with the temperatures o the

targets you will be viewing.

You dont want an inrared camera that cant measure the temperatures

you want!

Point #11: Buy an inrared camera with upgradepotential.

This is a no-brainer or any product you buy. This author is always trying

to be sure that what I buy has an upgrade path or some type o ormaltrade-in/trade-up program.

However, in the world o inrared cameras, it is not always possible. The

engineering and sophistication o the inrared detector, robotic

manuacturing techniques or specialty optics mean that some cameras

can be easily upgrade whereas other can not.

Except or the least expensive cameras, however, many inrared cameras

will allow you to upgrade the rmware to increase pixel counts and thermal

16


19/23

resolution, not to mention letting you upgrade all sorts o in-camera

eatures and unctionality. Wherever you can buy an inrared camera that

allows you to upgrade in this ashion, thats a key value to you.

Why? Well, its like youre buying your second boat rst without buying

your second boat rst! Its like having your cake and eating it too and

lets ace it, you dont get to do this too oten!

I there isnt an upgrade path in this ashion, you should ask i the

manuacturer routinely buys back used cameras in exchange or credit

toward a new inrared camera purchase. Youre not going to get top

dollar or your used camera, but you will get a air price.

This becomes more important when you see a eature that would

substantially increase your productivity or saety or, even help you

lock-in a competitive advantage. These might be eatures such as buying

a high denition inrared camera, or one with an embedded global

positioning system (GPS), or one with a wireless remote.

There are also new inrared cameras capable o detecting gas leaks, such

as volatile organic compounds (VOCs), methane, carbon monoxide and

dozens o other types o gases that need to be monitored. And there

are xed-mount, auto-alarm activated cameras that are ideal or seeing

through smoke, og or complete darkness typical conditions in many

manuacturing environments. Today, xed-mount inrared cameras are

ideal or re-saety applications in warehouses, coal piles or even waste

sites, anywhere spontaneous combustion is a potential problem.

The bottom line is i youre buying rom a manuacturer that has oered

ormal trade-in/trade-up programs, and makes all types o inrared cameras,

then youre buying rom a company that is in the position to continue

to service all your inrared camera needs. You need a company you can

grow with or at least an inrared expert watching your back!

17


20/23

Point #12: Buy an inrared camera rom amanuacturer with strong post-sale technicalsupport and certifed training.

I you are new to the eld o inrared cameras, you will obviously want to

think about customer service and technical support ater youve purchased.

In addition to FLIR being the worlds oldest and largest manuacturer

o inrared cameras or commercial applications, they also own and run

the worlds largest student training organization the Inrared Training

Center or ITC.

The ITC provides training regardless o what type o inrared camera you

own. They train students in all types o industries with a wide variation in

applications, regardless o the make or model inrared camera you own.

I you are really unsure as to whether or not to buy an inrared camera,

many have decided to enroll in training rst, beore they buy. Its always

better to have a camera and bring it to class, but i you are really unsure,this is a great option.

The ITC prepared this Top Ten List o why the ITC should be your inrared

SUMMARY

On behal o this author and the entire FLIR organization, we hope this

booklet has been inormative, i even a bit entertaining.

We have tried our best to give you our best knowledge and helpul hints

as you seek to purchase an inrared camera.

While we o course hope you will choose to buy a FLIR inrared camera,

we also know that as more and more manuacturers enter the market, the

choice o what to buy can become harder, i not more conusing, to make.

Like most things in lie, the best decision is made when youve done your

homework. This booklet gives you some straightorward ways to think

about the eld o inrared, how it relates to our everyday lives and what

we do but more to the point, please always ask or a demo. Get a demo

in the type o application environment in which you work not just in a

conerence room. Why? Because sometimes its easy to udge a demo in

a non-real conerence room-like environment. Lots o inrared camerasdo accurate measurements in an air conditioned conerence room, but

will they maintain their accuracy when they are exposed to hotter or

colder temperature dierences in actual working conditions?

I you ask or a demo, and see rsthand how an inrared camera operates,

you will have done your homework and youll make the right buying decision.

We have a ready sta o internal experts, sotware and technical support

technicians, direct sales engineers and application specialists, and a

growing base o excellent distribution partners. We all stand by ready to

answer any question you might have. So, please take advantage o what

we have to oer. Its a ree call and we are happy to talk to you.
