Hti-Xintai Higher Resolution 320 x 240 IR Infrared Thermal Imaging Camera. Model HTI-19 with Improved 300,000 Pixels, Sharp 3.2in Color Display Screen, Battery Included. Lightweight Comfortable Grip.

Update 2/7/23-the HTI continues to function without issues. I continue to find new and different ways to utilize the thermal imaging feature. Battery life has been excellent, no degradation that I can tell just yet. It does take several seconds to power up so you just have to get used to it. The camera's thermal and visual overlay does need to be adjusted if you are doing close up work vs. longer distances.Truly impressed! Right out of the box I realized there was significant potential with this HTI-19 thermal imaging camera. My first thoughts were to look at my own home. Even without any background in thermal cameras I was able to immediately utilize the high resolution of the camera and interpret areas that showed obvious signs of energy inefficiency. Areas missing insulation, joints to the exterior where caulking had cracked or split allowing air infiltration and gaps in door seals. With heating prices skyrocketing, improving each of these areas will likely have tangible results helping justify the use of the HTI-19. I fully expect that these same improvements would benefit summer cooling.As for the camera itself, it does not appear to be cheaply made and feels robust during use. I had no issues with fatigue and the rubberized like grip provides a secure hold.At the start I am leaving the basic thermal imaging settings at default till I am more proficient. These settings such as the Spectrum color palette and 0.95 emissivity seem to work reasonably well. I have noticed that as I move the camera(pan it) there is sometimes a very slight display hesitation as the image updates.Standout specs:-320x240 IR resolution(rare at this price point) and a relatively large display. -One button image or video capture with 3Gb onboard storage. -Simple USB charging and laptop or desktop connection capabilities. -Accurate real-time temperature measurements-Included carrying case and carrying strapImages and associated quantitative data will be .jpg captured at 320x240 resolution and can be modified with included/available software. This could be handy if you are presenting your findings to others. I recommend searching for then visiting the HTI-instrument website for the latest image editing software. The camera does contain the imaging software within its built-in storage but the website has newer revisions. If needed the onboard software can be moved and installed to your computer when you connect via the USB micro port. This HTI-19 has far more potential than just home energy efficiency. It does require some deeper understanding for more complex situations or environments. But the capability is there. It can be learned and applied to many other areas. With proper understanding, one area that I believe would stand out would be the ability to help diagnose water leaks/water intrusion. Even with only a few hours under my belt I feel I could potentially spot some of these water leak areas already.For me I see this tool as something to help my own home initially then maybe to help family and friend's homes. Beyond that, there are many possibilities. Yes you can spend hundreds if not thousands more on other IR cameras but at this price point with included features the dive into thermal imaging with this HTI-19 is worth thinking about.

Note: I've had this camera for close to 3 years now. The firmware version is 2.1.8 and I have not found a way to update it. But it's possible that cameras with newer firmware are out there and this newer firmware causes some of the problems people talk about in the reviews here.I use this primarily for hobby electronics, and the high thermal imaging resolution is a very big quality of life improvement compared to the cheaper Seek Thermal and FLIR One Pro I've used before. I also like the wide field of view, and relatively smooth frame delivery with much less stuttering than I am used to on the mobile cameras.Pros:- High thermal image resolution- 1/6 the price of the cheapest FLIR with the same thermal image resolution (E8, not sure why that one review is claiming the E5 has the same resolution)- Performs at the advertised refresh rate relatively consistently, I only notice stuttering when panning to areas that require a major recalibration of the color palette.- Good screen size- Good battery life, even after 3 yearsCons:- Hybrid view just blends the thermal image and the color image, it would be a lot better if it just highlighted the edges of objects based on the color images like in the FLIR cameras.- Color and thermal cameras are physically positioned around 1.5" apart so there is a lot of drift between the color and thermal images when switching from looking at something up close to looking at something far away or vise versa, and recalibrating every time is pretty annoying. Because of this and the previous con I usually just use the 100% thermal image mode, and the resolution is generally good enough for me to be able to easily tell what I'm looking at.- Thermal image is very noisy compared to FLIR, this is a shame particularly since some pretty basic noise and hot pixel removal techniques fix this issue almost entirely, and could have probably been implemented at little or no cost.- Camera startup is a little slow (12-15 seconds)- I don't use it to take photos/videos, but if you do you will likely be annoyed at the confirmation dialog for every photo/video you take.Other:- Use the USB cable it comes with, most of the microUSB cabled I have lying around did not work for data transfer- The battery is replaceable, although I haven't researched where I could buy one with the required connector

For the price, it's excellent. I use it for home inspections. 320x240 is the minimum thermal resolution I'd recommend using for that purpose. I'm able to find active wet spots with no problem with this camera. For this price point you wont get any cool features like wifi sharing. But if you're on a budget and just need a thermal camera that has good imaging, this is a great bang for your buck. Only issue I have with it is the micro-usb location. The cord it comes with is fine, others may not fit in the small recessed access slot. Other usb cords seem to charge the camera, but dont work for data tranfer when hooked up to my laptop. May not be making a full connection due to the recessed location?

I use this for Home Inspections. I've been waiting for prices to come down and quality to come up. This was an offer I couldn't refuse. I paid less than 4.5% of the price of what I was looking at a few years ago and this is better technology. It was marked down plus they gave me another 20% "15 minute only" deal on top of that. I guess that falls into impulse purchase territory. The one I was considering several years back was over 8.5 G's! Time will tell how long it lasts, but so far, I am impressed. The functions work great. Build quality seems top notch. I don't plan on using the video features, but it takes them, unlike one review I read. The photos look great and are easy to download using the cable and put in my inspection reports. Photos have three temperature measurements that you can list at the bottom. Center of photo, High and Low temperatures, all also marked at the locations on the photo. The blend between the photo and Thermal Image is easy to use and works great. Like I said, for the price, I am well pleased.
