The BSIDE HX3 is the only camera in this group that works without a phone. Its 240 x 240 sensor, 2.4 inch 320 x 240 screen and 25 Hz refresh rate make it a practical tool for quick inspections where you want to look at a screen, not a handset. The phone-attached cameras, the Thermal Master P3, the AMPBANK M192 and the VEVOR Thermal Imaging, are smaller and can produce higher-resolution images, but they depend on your phone, its battery and its connector. If you need a self-contained device for HVAC, electrical or home inspection work, the HX3 is the straightforward choice. If you already carry a phone and want the highest resolution per unit of size, one of the phone models will serve you better.
A self-contained imager in a group of phone attachments
The other thermal cameras on this site, the Thermal Master P3, the AMPBANK M192 and the VEVOR Thermal Imaging, are all phone attachments. They have no screen and no battery of their own; they draw power from the phone and display the image on its screen. The BSIDE HX3 is different. It is a complete handheld instrument with its own 2.4 inch TFT display, its own controls and its own memory card slot. That single difference decides most of the comparison.
A phone-attached camera is convenient because you already carry the phone. But it also means the camera is only as good as the phone: the connector must match, the phone must have enough charge, and the screen you are looking at is the one you also use for calls. The HX3 removes those dependencies. You pick it up, point it, and read the temperature from its own screen. For a technician moving between jobs, or a homeowner who does not want to install an app, that is a real advantage.
The trade-off is size. The HX3 is a handheld device, not a pocket accessory. The listing does not publish its dimensions or weight, so I cannot tell you how it compares in the hand. But the presence of a 2.4 inch screen and a memory card slot tells you it is a larger object than a phone dongle.
What the 240 x 240 sensor and 25 Hz refresh rate mean on site
The sensor resolution is 240 x 240 pixels. That is 57,600 individual temperature measurements per frame. In practical terms, it is enough to see the shape of a warm pipe behind a wall, a hot circuit breaker, or a cold patch of ceiling, but not enough to resolve fine detail like the individual components on a circuit board. The listing states this resolution and says it helps you detect problems early. It does not publish the thermal sensitivity (the smallest temperature difference the camera can show), so you cannot judge from the listing how well it will pick up a faint leak or a small overload.
The refresh rate is 25 Hz. That means the image updates 25 times per second, which is smooth enough that you can sweep the camera across a wall or a panel without the image lagging behind your hand. A slow refresh rate makes it hard to spot a moving target, but 25 Hz is a reasonable rate for handheld inspection work.
The temperature range is -20 to 550 degrees C (-4 to 1022 degrees F). The high end covers electrical panels, hot water pipes and many HVAC components. The low end covers most building inspection needs. The listing does not state the accuracy of the measurement, which is a significant gap. Without an accuracy figure, you cannot know how close the displayed temperature is to the true temperature, so treat the numbers as indicative rather than as a calibrated measurement.
The screen, the palettes and the file you take away
The built-in display is a 2.4 inch TFT LCD with 320 x 240 pixels. That is a higher pixel count than the sensor itself, so the screen is not the limiting factor in what you see. The listing calls it a full-viewing screen, which suggests a wide viewing angle, but it does not publish a viewing-angle figure. What matters is that you can see the thermal image without holding a phone at arm’s length.
Fifteen thermal palettes are available, from white hot and black hot to rainbow, iron red and several fusion modes. A palette changes how temperature differences are mapped to colours. White hot and black hot are the most literal: hotter objects are white or black respectively. Rainbow and iron red exaggerate contrast, which can help you see a small temperature difference, but they can also make it harder to judge absolute temperature by eye. The listing does not explain when to use each palette, so you will need to experiment.
Images are stored on a memory card. The listing says the card can hold more than 30,000 images. It does not state the card capacity, the file format, or whether the stored file includes radiometric data (the temperature of every pixel) or only a visual image. That matters: if you want to analyse the image later on a computer, you need the radiometric data. The listing says the camera can be connected to a computer via USB for further analysis, but it does not say what software is required or whether the analysis includes temperature measurement. Treat the USB connection as a way to get files off the camera, not as a guarantee of full radiometric analysis.
Where the HX3 fits against the phone cameras on this site
The phone-attached cameras on this site have their own strengths. The Thermal Master P3 is designed for iPhone and Android and includes a manual macro lens, which suggests close-up work. The AMPBANK M192 works with any USB-C iPhone or Android. The VEVOR Thermal Imaging claims 512 x 384 super resolution and includes a macro lens. Those higher pixel counts may give you more detail in the image, but they rely on your phone’s screen and battery.
The HX3 does not compete on sensor resolution. Its 240 x 240 sensor is lower than the VEVOR’s claimed 512 x 384. But resolution is not the only measure of usefulness. A self-contained camera is faster to deploy and does not drain your phone. For a home inspector who takes a dozen thermal images per property and then writes a report, the HX3’s built-in storage and screen may save time. For an electrician who wants to compare a hot breaker with a reference, a phone camera with a higher-resolution sensor might show more detail.
If you are choosing between these cameras, the decision is less about specifications and more about workflow. Do you want to carry a separate device, or do you want to use the phone you already have? The HX3 answers yes to the first question. The others answer yes to the second.
The gaps in the listing that a buyer should note
Several specifications that matter for thermal inspection are not published in the listing. The accuracy of the temperature measurement is not stated. The thermal sensitivity (often called NETD) is not stated. The field of view is not stated. The battery type and battery life are not stated. The weight and dimensions are not stated. The file format and whether images are radiometric are not stated.
These gaps do not mean the camera is bad. They mean you cannot judge those aspects from the listing alone. If you need a camera for work where accuracy is critical, such as verifying a electrical connection is within specification, you should look for a camera with a published accuracy figure. For general inspection work where you are looking for anomalies rather than measuring exact temperatures, the HX3’s stated range and resolution may be sufficient.
One more point: the listing says the camera is for home inspection, HVAC, heat pump and circuit break work. It does not claim to be a safety device. A thermal camera is not a gas detector or a circuit tester. It shows you temperature differences; it does not tell you whether a circuit is live or whether a gas is present. Use it as a diagnostic aid, not as a substitute for proper test equipment.
The standalone choice for quick thermal checks
The BSIDE HX3 is the camera to choose if you want a thermal imager that works on its own. Its 240 x 240 sensor and 2.4 inch screen are adequate for finding hot and cold spots in buildings, HVAC systems and electrical panels. The 25 Hz refresh rate keeps the image smooth as you scan. The 15 palettes give you options for different contrast needs. But the listing leaves out accuracy, thermal sensitivity and field of view, so it is not the camera for work that demands a calibrated measurement. If you need higher resolution or a more compact tool, the phone-attached cameras the Thermal Master P3, the AMPBANK M192 and the VEVOR Thermal Imaging are worth considering. For a self-contained device at a likely lower cost than a high-resolution phone camera, the HX3 is a sensible starting point.

Frequently Asked Questions
Can the BSIDE HX3 measure temperature accurately?
The listing does not publish an accuracy figure. It states a temperature range of -20 to 550 degrees C and a resolution of 240 x 240, but without an accuracy specification you should treat the displayed temperature as an indicator, not a calibrated measurement. For work where accuracy matters, look for a camera with a published accuracy, such as plus or minus 2 degrees C or 2 percent.
Does the HX3 work with a phone?
No. The HX3 is a standalone camera with its own screen and controls. It does not connect to a phone for display. It can connect to a computer via USB for file transfer, according to the listing, but the listing does not describe phone connectivity or an app.
What is the resolution of the thermal sensor?
The sensor resolution is 240 x 240 pixels. That is 57,600 temperature measurements per frame. The screen resolution is 320 x 240, which is higher than the sensor, so the screen is not limiting what you see.
Can I analyse the images on a computer?
The listing says the camera can be connected to a computer via USB for further analysis, but it does not state the file format or whether the images are radiometric (containing temperature data for every pixel). If you need to measure temperatures from stored images, confirm with the manufacturer that the files are radiometric and that software is available.
Is the HX3 suitable for electrical inspections?
The temperature range up to 550 degrees C covers most electrical panel work, and the 240 x 240 sensor can show hot breakers and connections. However, the listing does not publish accuracy, so you cannot rely on the absolute temperature reading for critical decisions. Use it to find anomalies, then confirm with a contact thermometer or a clamp meter. Also note that a thermal camera does not replace a voltage tester or a lockout procedure.
How does the HX3 compare with the phone cameras on this site?
The HX3 is the only standalone camera here. The Thermal Master P3, the AMPBANK M192 and the VEVOR Thermal Imaging are phone attachments that use your phone's screen and power. The HX3 has a lower sensor resolution than the VEVOR Thermal Imaging's claimed 512 x 384, but it does not depend on a phone. Choose the HX3 if you want a self-contained device; choose a phone camera if you want the smallest possible tool and already carry a compatible phone.
