Review of the FLIR C2 Thermal Imaging Camera
FLIR Systems Inc. is the leading manufacturer of thermal imaging equipment. In business since 1978, they?ve honed their products and support to a level of near perfection. The latest offering from the company, the FLIR C2, is the industry?s first entry-level thermal imaging camera that allows you to grab and go.
Like a Digital Camera for Heat
The C2 features a design not seen in other thermal imaging cameras. Instead of the traditional gun format, the C2 looks and feels like a standard digital camera or smart phone. The company calls it pocket-sized and They are dead-on ? this infrared camera easily fits in your pocket for fast access on any job site.
In addition to its size, the C2?s point-and-shoot nature is invaluable on a job site. For example, if you suspect heat loss from a window, you can double check your hunch by getting a reading from the camera. If you think your client?s windows aren?t living up to their claims of warding off the sun?s rays, just point the infrared camera at it and check the readings.
If you're not familiar with thermal imaging products, the C2 is a good starter model, as the interface is user-friendly. Advanced users can calibrate the settings to meet their needs, but if you're not tech-savvy, you can use it'straight out of the box without having to worry about making any complicated adjustments.
The C2 is lightweight and compact, making it easy to slip into a tool belt pocket, but it's not so lightweight that you'll have to worry about breaking it the first time you drop it or if it accidentally bumps into your other gear. Contractors looking to purchase their first infrared camera would do well to look into the FLIR C2.
C2 Hardware
The basic hardware is simple, featuring a capacitive touch screen for viewing images and accessing the menu. The touch screen is responsive, but not so sensitive that it will accidentally bring up the menu while you're working. A large shutter button makes it easy to take a shot of your target and there's a smaller (but still easy to find) power button nearby. Both buttons are rubber, meaning that if you've got grease on your hands you can still depress them easily.
The front of the camera features three separate points: a lamp for additional light in dim environments, the infrared lens and a separate digital camera lens. The lenses sit in a depression surrounded by the same rubber coating that protects the rest of the camera, but there's no extra shelter from additional shutters or caps ? meaning contractors need to take care when placing the product in their pockets or tool bags.
The C2?s memory is internal and features 165 megabytes of space. it's not expandable or replaceable, but with the high compression rate of the C2, it isn?t an issue. When tested on 100 images, they only occupied 4 MB of memory space. A general contractor could easily use this thermal imaging camera on three or four whole-house jobs in one day without having to unload the memory.
Likewise, the battery is internal and rechargeable. The camera comes with an easy USB-to-mini-USB cable and a variety of charger plugs capable of fitting a variety of outlets, including American, Canadian and European. When the battery life was tested, it lasted for more than three continuous hours without showing any signs of stopping. You won't have to stop work to recharge the battery, which means less strain on your time between clients.
Easy to Use
It can?t be stressed enough how easy it is to use the C2. The camera allows users to switch between digital, MSX and straight thermal. While the straight digital and straight thermal reads are nice to have, it's the MSX that wins the prize. Overlaying the thermal image with the digital image, you can show your clients exactly where hot spots and heat leaks exist. And the image detail is greatly superior to anything offered by other thermal imaging cameras We've seen.
The C2 thermal camera offers different color scales, from full rainbow, to an orange-to-purple gradient (termed ?iron?) and grayscale, making it possible for you to choose the best setting to illustrate your point to clients. When tested, the rainbow was the easiest for a layperson to understand: the coolest spots showed as blue, while hotter areas are red.
The easy MSX readout is possible for clients to understand at a glance, but it also gives professional contractors a simple way to judge just how much heat loss or gain an area is giving off. You can use the camera?s ?lock? feature to focus on an object and take multiple images over a period of seconds or minutes and be able to tell if it's a constant heat loss ? as from a leaky window frame ? or a variable one, as could be the case with an appliance that?s on the fritz. Having the thermal overlay on the digital image also makes it possible for contractors to discern whether anomalous readings are from their area of focus (like bad insulation) or if something else in the room is throwing off the camera?s ability to pick up on things without blurriness, guessing or other problems.
it's easy to switch between Imperial and metric measurements ? and temperatures are displayed right on the screen. When targeting a specific area, the camera displays the temperature of the target, but also gives you a handy range on the side of the screen featuring the hottest and lowest temperatures in the camera?s field of vision, making it possible to judge ambient temperature.
The Downside
Not every camera is perfect, not even the FLIR C2. The accuracy and resolution of the infrared technology is not great for close-up images of under three feet. But if you need to show your clients a general image of how much their wall insulation has settled or how much heat is escaping from around their window frames, this camera will do the job very nicely.
The other downside to the C2 is that you need to connect the camera to a computer via USB cable to retrieve the images. there's no SD or microSD card to fiddle with, which is good, but carrying around cables can be cumbersome, especially if they get lost. The C2 has no Bluetooth capabilities, meaning you can?t easily transfer images to a smartphone or tablet, either.
The Test
When tested on a 100-year-old farmhouse, the C2 provided quite an eye-opener for the homeowners. They knew their insulation was bad and they knew their wiring was faulty, but a walk-through with the FLIR C2 revealed the extent of the problems.
Using the C2, the homeowners could see that the hot water tank in the basement was leaking into the ground below it. Their exterior basement doors, which were original to the house and had been unearthed just a year earlier, were letting in massive amounts of cold air. The basement itself stayed chilly ? the ambient temperature was about 68 degrees on a 90-degree day.
When surveying the walls, the homeowners were in for a further surprise. The original plaster and horsehair walls were sandwiched between the drywall interior and the siding. This kept the home insulated, but several key areas had started to crumble.
Wiring was another nightmare for the homeowners. They knew the whole house needed re-wiring, but the C2 unearthed several spots on the living room circuit that were dangerously close to catching fire.
The windows, some of which were original to the house, retained the heat of the day, but the frames were leaking copious amounts of air. The stained glass window that the homeowners were debating keeping needs a fix ? the C2 detected that the amount of heat coming through was the biggest obstacle in keeping their upstairs foyer temperate. A contractor could easily sandwich the window between two fixed storm windows, or apply a film to it to keep the sun?s rays at bay. Now that they know the source of the problem, they have options.
The FLIR C2 efficiently detected all of these problems, providing the homeowners with concrete evidence to present to their contractors; this invaluable knowledge will cut down on the time and money spent trying to fix their dream home.
Who Needs an FLIR C2?
If you need to pinpoint small areas or get detailed imaging, the FLIR C2 isn?t necessarily your best option and if you?d prefer transmitting your findings to your client digitally via phone or tablet, look elsewhere. it's also not the right equipment for on-the-spot, easily shared printouts.
However, for most general contracting work, it's a good, entry-level camera that won't break the bank and is backed up by decades of solid workmanship and stellar customer service. it's a sturdy device with few bells and whistles, but that?s exactly what the market needs.
If you're thinking of investing in an infrared thermal camera for your business, you?d do well to consider the FLIR C2. it's easy to use straight out of the box and advanced technical support and training are available.
The user materials are thorough and comprehensive and it easily handles multiple jobs per day, memory-wise and battery-wise.
