FAQ
1. Why is 384×288 referred to as the "golden specification" instead of a higher resolution like 640×512?
The core answer is quite simple: a balance must be struck between performance and cost. Although the mini 640 uncooled lwir thermal camera module has a higher resolution, its cost is more than 2-3 times that of 384×288. This would significantly increase the production cost of the product and thereby reduce its market competitiveness. In most civilian and industrial scenarios we encounter in daily life, such as security monitoring in residential areas, industrial maintenance in factories, and daily patrol by drones, 384×288 resolution is perfectly sufficient. It can capture clear thermal images and accurately distinguish the key details of the target. It won't waste performance due to a too high resolution and can keep the cost within a reasonable range. That's why it has always been called the "golden specification" in the industry.
2. How do the compact size and low power consumption of the 384×288 module specifically contribute to product development?
When we develop products such as portable thermal imaging devices and smart wearable equipment, the small size of the 384×288 module is truly crucial. It enables the products to be designed more compactly and lightweight, making them more user-friendly and significantly enhancing the user experience. Especially for devices like drones and portable detectors that rely on battery power, its low power consumption advantage is particularly prominent. It can extend the battery life by 30% to 50% compared to using high-power modules, eliminating the need for frequent charging and making the product more convenient to use and more practical. In addition, the small size and low power consumption can also reduce the heat generated by the module itself, which is very helpful for the stable operation of the entire device. It also reduces the difficulty of thermal design during the development process and saves a lot of effort.
3. Will thermal imaging lose its effectiveness in strong light?
Many people have this question: In fact, thermal imaging relies on detecting the thermal radiation of the object itself, so it will not be directly interfered with by visible light or strong light. However, it should be noted that strong light will cause the temperature of the surrounding environment to rise. As a result, the temperature difference between the target and the background becomes smaller, making identification less clear. Additionally, if the sunlight directly hits the lens, it may damage the detector, resulting in bad pixels appearing in the image. This point must be noted.
4. Why can't we see people behind the glass in thermal imaging?
This is actually related to the properties of glass. Ordinary glass blocks the transmission of thermal infrared rays. The infrared rays emitted by the human body cannot pass through the glass. Thermal imaging devices can only capture the temperature of the glass surface and cannot see the people behind the glass. They can only see the thermal image of the glass itself, so it is impossible to identify the people inside through the glass.
5. What are the key differences between the MD series with a resolution of 384×288 and the Mini 384 module with the same resolution? How should one make a selection?
The core detection performance and resolution of these two modules are the same. The key difference lies in the applicable scenarios and design priorities. The lens options for the Mini 384 module are more diverse, suitable for scenarios such as drones and handheld observation that require customized telephoto or wide-angle lenses, and can meet various customized needs. While the MD series focuses on extreme compactness, low power consumption, and standardized integration, making it more suitable for embedded machine vision, small intelligent terminals, and large-scale batch production equipment. It has better compatibility and mass production capabilities. To sum up simply: If you need customization and have multiple lens requirements, choose Mini 384; if you value standardized integration, low power consumption, and small size, choose the MD series.
