Works as expected, well worth the price if you need a simple thermal imager. Perfect for finding cold spots where insulation could be improved or hot spots on an engine or circuit board. The image helps you find problem areas, use the temperature reading for the center cursor to measure specific points. Construction is just 4 circuit boards bolted together, keeping costs low. Use the supplied USB-A to USB-C cable and any 5 volt USB wallwart, red LED is on when charging, a laptop USB-C charger will not work and instead actually discharges the battery. Charge time of about 3 hours taking maybe half an Amp from the charger, can then run the camera continuously for about 6 hours. State of charge is shown by the rectangle in the upper right of the display, all black is fully charged. Display freezes for 20 seconds when capturing an image. If you want a "Night Vision Game Camera" then search for that, those use a cheap cell phone camera element with the optical filter removed to allow through any near infrared light. This thermal imager is sensitive to the far infrared and has much lower resolution. The reference color bar is at the top of the display, the lowest currently displayed temperature is blue with a little bit of red added, the highest currently displayed temperature is bright red. The three cursors are at the center, at the coldest point, and at the hottest point (the cursor for the hottest point can be difficult to see against the red background). Text is displayed giving the temperature in degrees Celsius for each of the three cursors, plus the average temperature. The saved image file is exactly the same as what was on the display, and has a name between 00.BMP and 99.BMP. Technical Info: Frame rate is 2 frames per second and is updated as 2 interlaced fields in a checkerboard pattern, so half the image is updated at 4 fields per second. The thermal sensor provides the device with a 32x24 array of temperature readings, this is then interpolated into a 320x240 pixel image for the QVGA display. The cursors, annotation, and a reference colorbar are added on top of the image. Image from the display is saved as per Example-1 of the Wikipedia page for "BMP_file_format", except that the "Compression Method" is BI_BITFIELDS (not BI_RGB), and so there are three 16 bit bitmasks just before the start of the 320x240x2 bytes of pixel data at the end of the file (bottom raster first). Each 16 bit pixel data word has 5 bits of red in the MSB's, 6 bits of green, and 5 bits of blue. The emissivity of the object being measured is assumed to be 0.95, as shown by the constant "e=0.95" in the lower left of the screen. (Google "emissivity".) Given the extra information laid on top of the thermal image, it will be impossible to accurately recover the 32x24 temperature data from the sensor. The Adafruit MLX90640 breakout board would be a better choice for those interested in the raw 32x24 temperature data from the sensor, unless some future version of this device could save the 32x24 sensor data to a separate file. Manual should be revised to include the following: Red LED turns on while charging, off when fully charged. Use only a USB-A to USB-C cable such as supplied with the camera, do not use a USB-C to USB-C cable for charging or a USB-C laptop charger. State of charge is shown by the rectangle in the upper right of the display, all black is fully charged.

When you receive this take care to plug it into a wall and not a USB to charge it. Leave it for at least 4 hours so it can get a proper charge on it. This thermal imager will not give you very clear images, but it will show you temperature differentials which is super important when you are trying to weatherproof your house. That is what we are using it for. It shows you the coldest area within the screen and the warmest area within the screen. Once you get used to it, even though you cannot see the images you know what you are looking at based on temperature differentials. If you are looking to get this to see where hot or cold are leaking, this is the perfect thermal imager. I highly recommend this for this use. The battery life is very good and the temperatures are very accurate. I tested it against my laser thermometer and it was very accurate. I would say the value for the money is excellent. It is super easy to use. All you have to do is turn it on on the upper right hand side and point it at where you want to see the temperature differences. It also has other features on it where you can save pictures of the thermal images to your laptop. I don't know anything about that because that's not something I'm interested in using it for.

Finicky & fragile, but lots of fun. Performance is very good for the price. Perfect for experimenting. If you need something rugged for daily work you’l need spend a lot more $ to get a similar result.

Electronic components and sensors are fairly cheap nowadays, so there is no reasons why an infrared thermal camera should cost hundreds of dollars. This camera is not worth buying, considering that there are much better alternatives for a slightly higher price (like $99). It has a very low resolution at 24x32 (768 pixels) with relatively large lcd screen, thus magnifying the poor resolution conundrum. Also, it has issues with auto-scaling along with color palette issues (detecting min. and max. temp in a current frame when the temps differ significantly). Not worth buying, it is mostly a toy; look for better alternatives.

Temperature are not correct and image very poor.

Thought it would be bigger than it was and the charging ports hard to push in and pull it out when trying not to be hard on the product. Wish it had some kind of cloth case it came with but was just the cardboard box so risking scratching up the lens.

It's good for the price but honestly I don't know if it's worth it. There's such low resolution it can only give you results on like a 6x6 ft piece of wall. Although you could use on an entire side of a house for a VERY general sense of where heat is escaping.

This device works as designed. The resolution is very pixelated, Lets face it, you cant expect a high resolution thermal camera for sub $100.00 price. The picture is very usable, and the camera works as designed. depending on the industry or location you should be able to make it work. You can access/download all the pictures via the USB cable to your laptop or PC. If you require high resolution images, you may want to spend a bit more $$$ for the resolution you require. when you're looking for a thermal anomaly, this device should be able to help you. everything works out of the box and the manual is easy to understand. If I find anything further during my testing, I'll update this review.
