Here's the bottom line: most teams don't need the expensive FLIR.
I've spent six years as the procurement guy at a 40-person electrical contracting company, auditing every dollar we spend on test equipment. Roughly $180,000 in cumulative purchases later, the pattern is clear. The $699 FLIR C5 handles about 80% of what people think they need a $3,000+ FLIR A35 for. That's not a criticism of the A35. It's a fit problem. Honestly, the more I audit our spending, the more I see money wasted not on bad tools, but on the wrong tier of the right tool.
And yes, this is a FLIR C5 thermal imaging camera review of sorts. But it's not one of those reviews that obsesses over thermal sensitivity specs and MSX algorithms. I'm not an engineer — I'm the guy who signs the purchase orders. What I can tell you is what these cameras really cost to own, and where the value is for a typical inspection crew.
Why Listen to Me
Quick background so you know where this perspective comes from. I manage procurement for a company that does commercial and light industrial electrical work — panel upgrades, motor control centers, periodic infrared scans of switchgear. Our test-and-measurement budget runs about $30,000 a year, and I've been tracking it invoice by invoice since 2019.
In that time, I've compared quotes from 15+ vendors, built a TCO spreadsheet that factors in calibration costs, warranty turnaround, and even the time crews spend learning a new interface. I've also made my share of mistakes. The worst: in 2022, I bought a cheaper thermal camera from a brand I won't name. Saved $400 upfront. The resolution was too low to catch a failing busbar connection, and we had to redo the entire survey. That $400 "savings" cost about $1,200 in rebilled crew time and a seriously annoyed client.
It took me about 40 purchase orders and two bad bets to understand something that sounds obvious in hindsight:
The cheapest tool is the one you have to use twice.
Price per use matters more than sticker price.
The FLIR C5: What It Is and What It Isn't
So, the FLIR C5. It's a handheld camera that looks like a chunky pocket camera, which is basically what it is. It gives you a 160×120 thermal sensor, FLIR's MSX image enhancement (which overlays the visible-light photo onto the thermal image — genuinely useful for making sense of what you're looking at), and Wi-Fi upload to FLIR Ignite cloud storage. The price has been steady around $699 (as of January 2025 — verify current pricing before you buy).
Here's the thing: for electrical inspections, that spec sheet is enough. The C5 will spot a loose connection in a breaker panel. It'll catch a failing motor bearing before it locks up. It'll show you the exact spot on a three-phase board where L2 is running hot. A maintenance tech with a C5 found a failing splice in five minutes last year — a job that would have taken an hour with a clamp meter and a thermal paint test.
What most FLIR C5 thermal imaging camera reviews don't tell you: the limiting factor is rarely the sensor. It's whether the person holding it understands thermal contrast and emissivity. I've watched engineers with $10,000 cameras produce useless thermal images, and I've watched a tech with a C5 find the problem in minutes. The camera is a tool. The judgment is the real asset.
One thing to budget beyond the camera itself: a basic protective case and maybe a small tripod. The C5 has a rubberized grip and an IP54 rating, so it survives job sites, but the screen will scratch if you're careless. A $30 tripod massively improves the quality of time-sequenced images for follow-up comparisons. Little stuff — but it shows up in the TCO.
The FLIR A35: Frequently Overbought
Now the FLIR A35 thermal camera — the one that gets people into trouble. The A35 is a fixed-mount camera. No battery, no screen, no carrying handle. It's designed to be bolted onto a production line or substation, wired with Power over Ethernet, and left running 24/7, streaming thermal data to monitoring software. It's a continuous-monitoring device, not an inspection tool.
Watching a procurement manager buy an A35 for periodic walkthrough inspections is like watching someone buy a fleet truck to commute to the office. It works, but the economics are wrong. The A35's price typically lands in the $2,500–$4,000 range depending on optics and configuration (based on quotes I've collected from FLIR distributors, early 2025). And that's just the camera. The total installed cost is often 30–50% higher once you account for mounting hardware, network infrastructure, and a license for FLIR's thermal monitoring software.
I'm not saying the A35 is overrated. I'm saying it's overbought. Our company has exactly one A35 — on a plastics plant's granulator system, where a bearing failure stops a $40,000-per-hour line. That's where it earns its keep. For everything else, we use handhelds.
So the question I ask every internal stakeholder who requests an A35 is simple: "Do you need to monitor continuously, or inspect periodically?" If the answer is "periodically," you don't need the A35.
The 568 IR Thermometer: The Workhorse Nobody Reviews
And here's where I'll go against the grain. A lot of the FLIR camera reviews list accessories and software add-ons. I want to make a case for an old-school tool that costs a fraction of what any thermal camera costs: the 568 IR thermometer.
We carry one on every truck. Why? Because it's fast. If a crew is doing a breaker scan, they don't need to power up a thermal camera, wait for it to boot, take an image, and later analyze it. They need a number. The 568 gives a non-contact temperature reading with dual laser sighting in seconds. It won't show you a thermal image, and it won't catch a temperature gradient across a panel. But for daily pass/fail checks, it's the tool that actually gets used.
It took me a while to appreciate the 568's role in the ecosystem. I used to think it was a toy compared to our FLIR units. Then a senior tech told me, plainly, that he used the 568 ten times a day and the thermal camera twice a week. That was a reality check. Buy the right tool for the frequency of the task.
This whole cost-versus-frequency calculation got me thinking about how far back it goes. I stumbled on a historical footnote the other day: an 1880s Gold Coast mining company's procurement records showed a microscope purchased for ore analysis was one of their largest equipment line items that year. A single microscope. For a mining operation. I laughed, because some things never change. The technology moves from brass and glass to uncooled microbolometers, but the question is always the same: will this tool pay for itself in better decisions?
Where to Buy IFM Inductive Sensors Online
One more procurement note, because people ask me this directly: where to buy IFM inductive sensors online. I've bought a lot of these for automated equipment we maintain. IFM makes solid, reliable inductive sensors for position detection — my default is their M12 connector series because replacement takes minutes, not hours. I order them from authorized distributors like RS Components or Mouser, and I steer clear of marketplace listings with suspicious discounts. Counterfeit sensors are a real problem, and a fake sensor fails at the worst possible moment. Stick with authorized channels, even if it costs slightly more. (Note to self: I still owe that team a comparison table of the IFM vs. competing sensor pricing — the numbers are gathered, the spreadsheet is not.)
When to Ignore Everything I Just Said
Now the honest part: when is the C5 not enough? If your work involves small components — populated circuit boards, tiny SMD joints, or anything where you need to resolve a target under about 5 mm — the C5's 160×120 sensor is going to leave you guessing. For that kind of work, step up to something like the FLIR E5-series or higher with more resolution and better thermal sensitivity, and budget accordingly.
And the A35 is genuinely the right call if a failure on your watch carries a five-figure-per-hour price tag. At that point, the monitoring capability isn't a luxury. It's insurance, and the A35 is a cheap premium for coverage. Just don't buy it because it's "the industrial model."
On the small-order front: don't let anyone make you feel like your purchase is too small for good service. I've had distributors essentially ghost a $700 C5 inquiry. Their loss. The dealer who took that $700 order seriously is the same dealer I handed a $25,000 A35 project to three years later. Small doesn't mean unimportant — it means potential.
Prices mentioned here are as of early 2025, based on quotes from FLIR's authorized online channel and distributor sites. They will change. Verify current pricing before you commit.
Bottom line: match the tool to your actual inspection frequency, calculate total cost of ownership before you sign anything, and don't let anyone sell you a fixed-mount thermal camera for a job a handheld can do. That's the whole ballgame.
