Since people are already accustomed to delicacies made from ordinary ingredients, there is no novelty. What they want to try more is the game that is not common on the table. Due to the serious shortage of supply, the price of game has been rising again and again. The price of an ordinary domestic pig is only about 2,000 yuan, but the price of a wild boar has skyrocketed, at least over 10,000 yuan, and the price has increased by less than ten times. Precisely because of this huge market, hunting is loved by more and more people. The more prey you catch and the rarer it is, the more you can bring in very considerable income. In another sense, this is also equivalent to an outdoor sport. While bringing income, it can also strengthen the body and enhance physical fitness. Hunting is generally carried out at night. Many animals become lazy and motionless at night, making it easier to catch them. If you don’t have a good device, the difficulty of hunting can be imagined. If you are too close to the target, it is easy to be discovered, disturbing the animal, and it is likely to run away directly. Choosing a good device is of great significance. The night vision equipment that can be used at night mainly includes infrared thermal imagers and night vision devices. The working principles of these two devices are different, and each has its own advantages and disadvantages.

Infrared thermal imagers use infrared detectors and optical imaging lenses to receive the infrared thermal radiation energy of the target to be measured, and the distribution pattern is reflected on the photosensitive element of the infrared detector to obtain infrared thermal images. This infrared thermal image corresponds to the thermal distribution field on the surface of the object. In layman's terms: infrared thermal imagers convert invisible infrared energy emitted by objects into visible thermal images. Different colors on the thermal image represent different temperatures of the object to be measured.

Night vision devices are night vision devices with image intensifier tubes as core components. When working, they do not use infrared searchlights to illuminate the target. It uses the light reflected by the target under weak light, and enhances it on the fluorescent screen through the image intensifier to observe the target.

By comparison, it can be found that the difference between infrared thermal imagers and night vision devices is still very obvious. In general, infrared thermal imagers are easier to find targets; night vision devices are easier to identify targets and see the facial features clearly. Therefore, if used for hunting, infrared thermal imagers are more suitable, and you only need to find the exact location of the animal.

There are many brands and models of infrared thermal imagers for hunting, and the prices range from thousands to hundreds of thousands. It is difficult for novices to choose, and they don't know where to start. So, how can you buy the most suitable infrared thermal imager? Here are some tips for buying infrared thermal imagers:

1. Look at the detector pixels

Infrared detectors are divided into cooled and uncooled types. Cooled infrared detectors are mainly used in high-end military equipment and are expensive. Uncooled infrared detectors can work at room temperature, and the volume and power consumption are greatly reduced. Most civilian fields use uncooled infrared detectors.

Before purchasing an infrared thermal imager, you must know that the detector pixel is the most important parameter for choosing an infrared thermal imager, which will directly affect the final imaging effect. The higher the detector pixel, the clearer the image and the better the experience. Common detector pixels are: 160*120, 384*288, etc., and there are also lower pixels, such as: 60*60, 80*60, 100*100, etc.

2. Display screen resolution

Before purchasing an observation infrared thermal imager, another important parameter to understand is the resolution of the display screen. When the number of infrared detector pixels is certain, the resolution of the display screen will directly affect the image clarity. The higher the resolution of the display screen, the clearer the image and the better the experience. Common display screen resolutions are: 1280*720, 960*540, 800*600, 640*480.

3. Whether it has the function of taking photos and recording videos

Whether it has the function of taking photos and recording videos is also the most important parameter of the infrared thermal imager for hunting. Hunting is prohibited by law for the first and second level protected animals in the country. But if you happen to encounter it, you can take a picture of this precious scene as a souvenir, or you can hand over this precious image data to the relevant nature conservation unit, which may serve as a very important basis for the decision-making of the nature conservation unit, which is beneficial to the country and the people. This type of infrared thermal imager is very convenient to operate. Just press the photo or video button to take a photo or record a video immediately, with basically no delay. This is crucial for capturing precious image data because opportunities are fleeting. Ordinary infrared thermal imagers without photo or video functions are difficult to do this. They are very troublesome to operate and need to be connected to an external display screen. It is difficult for one person to operate. At least two people or more are required. The disadvantages are very obvious.

4. Field of view and spatial resolution

The field of view of an infrared thermal imager is the maximum spatial range that the thermal imager can detect. The larger the field of view, the larger the range that the infrared thermal imager can detect, but it cannot be said that the larger the field of view, the better, because when the infrared thermal imager pixels remain unchanged, the larger the field of view, the rougher the infrared thermal imager picture.

The spatial resolution of an infrared thermal imager refers to the minimum area that the infrared thermal imager can identify. The smaller the spatial resolution, the more accurate the detected temperature, the richer the information contained in the infrared thermal image, and the clearer the image.

5. Look at the brand

As a high-tech product, many people have a hard time choosing infrared thermal imagers. In the case of not understanding the technology or the product, there is another more intuitive way to choose, that is to look at the brand. Generally, the quality of products from big brands is relatively guaranteed. They have been accumulated over decades or even hundreds of years, have a good reputation among users, and can withstand the test of the market. Therefore, if novices do not understand the product or the technology, it is recommended to choose big brands with good reputations.

So, which brands of products are more popular with users?

In May 2017, Oonica Optics (Wuhan) Co., Ltd., through market research, questionnaires, user visits and other methods, counted the most influential brands in the global hunting infrared thermal imager industry in 2017.
