My first encounter with professional-grade thermal imaging equipment was in 2015 when I commercially operated unmanned aerial vehicles (UAV) for agricultural surveys. At that time I had acquired a 30Hz 640×512 pixel sensor specifically designed for UAV applications. I had also used this sensor for other tests and analyses, including electronic design, residential development, and home improvement applications. Using it outside of a UAV was, however, quite painful, as it just wasn’t designed to be used in a handheld environment. After testing out other lower-cost models designed for smartphones, I was quite disappointed by the image quality, handling, and integration. Neither one of the available thermal cameras satisfied my needs and expectations. I had then discovered PerfectPrime’s product lineup and liked the IR0019 with its technical specifications. Despite the resolution not being on par with my first thermal imaging camera, it is more than sufficient for my purpose. Therefore I made the decision and ordered the IR0019.What you getI purchased the camera directly from PerfectPrimeEU through Amazon Marketplace. It arrived in a padded envelope via FedEx, shipped from HongKong by PerfectPrime. For this reason, I had to go through the customs import process in Germany, supply proof of payment and had to pay an additional charge for import taxes and duties. In my case, however, these charges weren’t that much. This does have to be factored into the final price you pay, in addition to the price listed on Amazon, though. I would recommend PerfectPrimeEU to either use Fulfillment by Amazon in Europe or ship from a European warehouse to avoid this risk and additional effort for other customers.When you open the envelope, you have an anti-static bag with all the goods on it. These include the transport case with a shrink-wrapped camera inside, a Micro-USB cable, a USB charger, a neck strap for the transport case, a small documentation leaflet, and a thank you note for the purchase. In addition to the product, PerfectPrime offers an elite full technical support and a 30 day full-refund warranty, if you are unsatisfied with your purchase.Technical DetailsThe PerfectPrime IR0019 is a handheld thermal imaging device with an integrated 3.2″ full angle color display, an integrated rechargeable 18650-type lithium-ion battery, a 9Hz 320x240px thermal imaging sensor (microbolometer), and a 30Hz 640x480px visible light camera sensor. All is packed in an ergonomically designed case for handheld operations. The thermal imaging camera can be protected with a pivotable lid on the front, making it quite a rugged device by design. Its thermal specifications include a 0.07°C thermal sensitivity, a 27° x 35° field of view (FoV), a fixed 0.5m focus distance, a temperature range of -20°C to 300°C (-4°F to 572°F) and an integrated 3GB memory. The emissivity of the surfaces captured can be adjusted from 0.1 to 1.0 to allow for correct and calibrated temperature readings. The camera’s memory cannot be upgraded or swapped, but is accessible through a Micro-USB cable. Images are stored as 8-bit JPG files with a final resolution of 240x320px. One of the great features of the IR0019 is the adjustable visible image overlay, which is available in 5 steps of 25%, from 0% to 100%.User ExperienceThe thermal imaging camera has a simple, yet clear user interface. The front of the camera has one trigger button to capture an image. The rear of the camera features a set of eight buttons below the screen consisting of four arrow keys and four function keys. The first one is the power button, which has to be pressed long to either power the device up or shut it down. The second key is a menu key, opening and closing the software menu. The select key is used as the confirmation key for most of the functions, whereas the enter key can be used to close the current sub-menu. The first set of sub-menus must, however, be opened with the arrow-right key. The menu is okay but may feel slightly less-intuitive at times. It’s easy to get used to it though. The arrow-up key shows and hides an additional information layer on the bottom of the screen. The arrow-left and arrow-right keys are used to adjust the level of the RGB image overlay. Additionally, the RGB camera’s overlay positioning can be adjusted in the menu via image registration in order to compensate for a potential parallax offset, making it an excellent feature for semi-translucent recordings. A selection of five different color palettes is provided, including spectra, iron, cool, white and black. These can only be changed during a live inspection in the menu and cannot be altered after an image was taken.PerformanceThe performance of the sensor and the thermal imaging camera itself is quite astonishing, especially considering how much value the customer is given for the price. The images from the microbolometer are clear and have a smooth transition in colors and brightness. They are captured quickly without noticeable delays. The battery has barely lost any charge for the time I have been using the IR0019 so far. Overall, this device should prove very useful in a professional environment. The user interface is responsive, but not quite as instant as a modern smartphone, but that’s a whole different category of device. I have not experienced any glitches so far, which is an important aspect of any software-based device.SummaryA thermal imaging camera can be a very versatile device and used in many different ways including home improvement, residential development, energy-efficient design, hardware engineering, search and rescue operations as well as educational projects. With the PerfectPrime IR0019 handheld thermal imaging camera’s high quality, excellent reliability and astonishing price-performance-ratio, the user is encouraged to apply this technology on a regular basis.

Bought this camera to use in a business environment for office visits. First impressions of the packaging and the way the unit feels are good. Provided with a nice case. Comes with manual, USB charging cable 16gb memory card and manual. I previously had devices from PerfectPrime and was satisfied with them. I especially liked their CO2 meters as I found them most accurate among other I have tried.So before purchasing, I read reviews on their other thermal cameras and noted flaws people were talking about. However, this camera seems to be addressing issues with other cameras they have. So my experience here is as follows:1. Upon powering up, it took a bit of time until it booted into the android OS. I went to the menu, and did a factory reset. This seems to trigger some sort of an update, after which the camera boots much faster now. Now note that it only takes about 10-15 seconds to boot for the first time. When it’s in stand by mode, the power on is instant, which is nice. No delay whatsoever. The camera is very easy to use. I didn't even read the manual as it's all self explanatory.2. The screen’s initial brightness setting is at 50%, and it’s bright enough to use even outside with moderate lighting. However, if you set it 100% it’s very bright, so there are no issues using it outside. This I read was previously an issue with their older cameras3. I first switched the camera to non-human mode to check how it measures the temps in general. Found it quite accurate at close and far distances. I’d say a few degrees of variation for distant items is normal. But it’s very convenient to use in camera more without IR filter to quickly measure any object temperatures.4. Now, to it’s main feature – the human body temps detection. It’s actually quite impressive! The temps measure speed is virtually instant. So measuring it in an office environment gave me an idea instantly about the visitors temps. As soon as they walked in an office, the camera provided instant temperature measurement on a moving subject. That’s something I did not even expect. And the accuracy is very reliable in my experience up to 3-4 meters. It probably works further than that, but that’s how the camera was positioned. I mounted on a small tripod and placed it on a reception desk. We had no incidents with high fevers that day, but one child had 37.8 at the forehead region and the camera detected that immediately and sounded an alarm.I tried different adjustments, and found that the way it’s configured from the factory is virtually optimal, although I liked the wide-gaussian filter to be the most accurate for measuring the body temps.I like the fact that lens are not just a close up lens. It’s probably close to a 50mm camera lens, where you don’t have to be too far away from the subject to get a good body area, which is usually a problem with other thermal cameras.I also had a chance to compare it with FLIR camera, and found that this camera outperforms FLIR as a human temperature detector because of its accuracy, much faster SPEED, convenience and overall design to be a specialized human body temp camera. It also has automatic image capture for people who have fevers, which is great. When I looked that the memory card contents, I found that is captures CSV files with all temps readings and meta files of all measurements.I’ve owned other similar devices in past but find this to be the best of them and can actually replace all of my home thermometers as well. :) Good tool for family use as well.Other things I liked is having an option to replace the battery when needed, touch screen and ability to store images on an external memory card.As for the improvements, personally I’d want to be able to tweak and adjust the IR sensor temps and to calibrate it to my needs. Sometimes, depending on the environment you’re in, the human skin can reflect different temps in cold environments, so a compensatory adjustment is a must in my opinion. I find that the IR sensor resolution quite sufficient for body temperature measurements, I don’t think you need a higher resolution for this purpose alone.By the way, in order to turn the fever alarms on and off, you have to press and hold the main trigger button on the handle for a second or two. But once the mode is on, you can adjust the trigger temps with left and right buttons.Overall, in my opinion, if you need to quickly and reliably measure passing visitors for temperatures, this camera seems to be a great solution.

This is the first thermal camera I've ever owned. I chose it because of the low price point and decently high resolution specs compared to similarly priced named brands such as FLIR. However, after trying it out over the last few days, I've come to the conclusion that the resolution specs are unrealistically high in relation to what useful images can be obtained on it.One major problem with this camera is the high noise level of the tiny sensor (as another reviewer here pointed out). A good analogy is to compare it to the hobbyist toy telescopes sold at department stores for around $100. Those toy telescopes invariably have unrealistically high magnification claims such as “300x magnification power.” In actuality, no useful image can ever be produced at 300x by those small toy telescopes because their primary lenses are too small to gather enough light to produce a useful image at such high magnification. 80x magnification is about as high as one can realistically get on those tiny scopes while getting acceptably clear images. 80x (realistic) vs. 300x (advertising claim) is a big difference. The same principle of overly optimistic specification applies to these relatively inexpensive Chinese-made thermal cameras. If the tiny sensors were designed for a smaller resolution such as 80x60 instead of 220x160, the noise level might have been acceptable.The noisy images I get from this IR camera appear as though they are viewed through a very dirty screen door. Can I still use the images? Perhaps yes. The answer really depends on what the application is. My primary interests are detecting home energy loss and active water leak around my home and at my two rental properties. For such uses, rough, noisy images maybe totally sufficient. But, that doesn't mean the highly noisy images don't bother me.Besides the high noise level, there are a few design flaws and nags with this IR camera:1. It should have come with a built-in laser to match an area of the thermal image to the actual physical location (for example, a cold spot on a large blank wall). The camera comes with a visible image feature, but that doesn’t help much when viewing large featureless areas such as blank walls and large ceilings. Without a laser point as reference, it’s very difficult to associate the thermal images to the actual physical locations. Laser pointers are dirt cheap and it should have come with one built-in that can be easily turned on and off with a switch.2. I can’t make any sense out of the rainbow temperature scale because it’s a fixed scale and the upper and lower ends are not labelled. The rainbow slide doesn’t dynamically change based on the max and min observed temperatures within the screen. Because of these two flaws, it’s not possible to look at a color on an image and compare it to the scale in order to estimate the temperature for that particular color on the image.3. The screen is in portrait mode. I personally find landscape mode more useful for my applications.4. It has no lanyard and no way to attach one. I always worry about dropping the camera when using it.5. The instructions are abysmally terse and incomplete, which is typical of most inexpensive imported Chinese products. Eventually I was able to figure everything out by trial and error over the course of a few days.These are just my initial impressions. I’m still trying it out. I’m still undecided as to whether to keep it or return it and bite the bullet by spending over a thousand dollars to get a much nicer an entry-level pro-grade camera. As the saying goes, you can buy a properly built expensive tool once or you can buy a cheaply made inexpensive tool three times. I have a feeling if I keep this relatively cheap Chinese-made IR camera, I may well end up having to buy these IR cameras three times.

いまどき32×32と聞くと非常に少なく感じますが1000箇所の温度が一気に測れると考えると十分に感じます。しかも1000度まで測れるものとなると高価な高温対応のプロ機に限られるのでなおさらです。　撮影モードはIR、オーバーレイ(IR50％可視50％)、可視の3モード、オーバーレイでは可視とIRの位置調整は出来ますが合成比率の調整は出来ません。撮影するとモードに関係なく撮影画像と温度分布(CSV)とmetaファイルの3つが作成されます。CSVデータは表計算ソフトで開いてカラースケールを適用すればIR画像が出来上がるので撮影を可視で行い後処理を頑張ればお好みのオーバーレイを作ることも可能です。　試しに無調整のオーバーレイでストーブを撮るとこんな感じ、寄りと引きで温度が違うのは解像度不足による分解能の影響と思われます。寄った方が分解能があがり正確な温度が撮りやすくなりますが、寄りすぎると熱さで壊れるので悩ましい。放射温度計AD-5616で測ると上部640度、側面330度くらい。開放環境でこのくらいの温度になると微妙な測定位置の違いで10度くらいはすぐ変わりますし、放射温度計の分解能(測定範囲)の問題もあるのでこのくらいはセンサー精度というよりは測り方による違いです。　難点は、高温測定用の機種なせいか最高と最低で10度くらいの温度差がないと綺麗に写りません。
