Waterproof, anti-drop, dustproof, rugged phones have been a long time, but now the large screen touch phone is prevalent, tough phones gradually fall into a niche, but it still has its own value of existence. For specific groups of people, rugged phone is still essential. Delivery boys, engineers, field workers and even explorers, their living environment is always difficult to avoid high temperature, high humidity, high altitude, cold, wind, sand and mud, vibration and even rain soaked and other harsh conditions. This time ordinary cell phones may not be able to withstand, a rugged phone that can accompany them, is undoubtedly the best choice. The new AGM Glory Pro, the first thing worth mentioning is that AGM is widely known for its waterproof, dustproof and dropproof skills, weighing 370g, it definitely stands up to the test in terms of protective materials. What's more, this generation of AGM Glory Pro does not stop there, it also challenges the natural enemy of electronic products - the cold. Every winter, the ordinary phone is basically unable to be used outdoors. This is not only because of freezing hands, but also because the performance loss of lithium batteries in low temperatures will be greatly increased, so the phone will trigger protection in low temperatures, power down fast or directly black screen shutdown, can not be used. To solve this problem, the AGM Glory Pro starts with both the battery itself and thermal protection. The battery itself also uses a more cold-resistant electrolyte and porous cathode material, solving the problem of lithium battery performance dropping dramatically at low temperatures; in addition, the phone enhances water insulation and designs the copper tube from SOC to battery internally, using the SOC as a heat source to provide thermal protection and reduce the impact of temperature on its performance.  Even in the bitter cold of -30°C, it is able to provide a long working time of 5.3 hours, while other phones will just quickly black out and shut down, leaving you paralyzed. Although we cannot test the performance at -30°C, we can see the performance of AGM G1 Pro at 0°C with the help of refrigerator. Even when placed in water and frozen into ice, the AGM Glory Pro still works properly. This proves its excellent water barrier capability on the one hand, and its low-temperature resistant design is really effective. Remove the phone to see the temperature of the core components. Although the surface is immersed in ice and water mixture for a long time, the temperature reaches 0℃ or even lower, and it is a bit cold in the hand. But the battery still keeps working at 5°C, and the core temperature is kept at about 15°C, providing constant thermal protection for the battery. The real technology can withstand the torture of the cold.

When we see some technical terms of cell phones or cameras, such as MP, IR Lens, etc., we may be confused as to what the meaning behind them is and how to define the good or bad of the products. Next in this article, I will explain in detail the meaning of these terms to help you understand and better select products. 1, What is MP? MP stands for mega pixel. mega means one million and mega pixel means one million pixels. A "pixel" is the smallest unit of light sensitivity on a camera's light-sensitive device. Like the silver grains of photographic film in an optical camera, the light-sensitive spots on the "film" (memory card) of a digital camera are pixels. To get a high resolution (i.e., fine photos), you must have a certain number of pixels. Of course, it is not the case that the larger the number of pixels, the clearer the photo will be, but the clarity of the photo is determined by the "dot image", not the number of pixels. The number of pixels is the sum of effective pixels, and the dot pixels are how many pixels per dot (inch, etc.). 2, what is IR? IR lens is infrared lenses, mainly used for night vision, surveillance cameras. It uses a special optical glass material and the latest optical design methods to eliminate the visible and infrared light focal plane shift, so the light from the visible to infrared light area can be imaged in the same focal plane, so that the image can be clear. In addition, IR infrared lens also uses a special multi-layer coating technology to increase the transmission rate of infrared light, so the camera with IR lens is far more effective than the camera with an ordinary lens to monitor the distance at night. Ordinary lens at night with infrared light, the focus position will change. IR lens focus in infrared light and visible light are consistent. It is also called the flush lens. Because of the night use, the aperture should be larger than the ordinary lens. Aperture is called the relative aperture, expressed in F, indicating the effective diameter of the lens and the relationship between the focal length. The smaller the value, the better the effect.  3, what is Macro Camera? Macro lens is a special lens used for macro photography, mainly for shooting very fine objects, such as flowers and insects, etc. Modern macro lenses are also good with new optical technology to compensate for a variety of aberrations from macro to infinity range of focal lengths, not only for shooting flowers and still life, and portraits, landscapes, etc., is a highly versatile lens. Macro photography allows for close-up images of tiny or detailed objects, such as insects. Photographers use macro lenses when shooting close-ups because of their ability to focus at very short distances. Macro lenses are designed to allow for life-size images or better Macro photography has been used to capture certain details on objects and also to capture details that would not normally be seen without a magnifying lens.

Here, we need to understand a basic concept: decibel - the unit of sound pressure level (symbol: dB), for every doubling of sound pressure, the sound pressure level increases by 6 dB.  1 dB is the sound that the human ear can just hear; generally speaking, 15 dB or less we can consider it to belong to the " silent "; and 20 dB or less we consider it to be quiet.  20-40 dB is about the murmur of a couple's ear. Normal environmental noise intensity in 30-40dB, relatively quiet and comfortable; 40-60 dB belongs to our normal conversation sound, when more than 50dB (45dB at night) may affect sleep and rest, so that the normal physiological function is affected to a certain extent.  Above 60 dB is a noisy range, 70 dB we can consider it very noisy, interfering with normal conversation and communication, making people feel distracted and unfocused.  Above 90 dB (the upper limit of the national noise tolerance) will cause hearing damage and lead to other diseases, and stay in the space of 100-120 dB, if there is no accident, one minute humans will have to be temporarily deaf (deafening).  But there are cases where a high volume speaker is very necessary.  Do not forget that the above data is for normal people, for hearing problems in the population, such as the elderly, they have different needs. It is possible that what we generally consider as noisy sound is just right for them, so a smartphone with a good quality loud speaker can help them hear better.  For some people who work in a very noisy environment for a long time, such as construction workers, the surrounding environment may be more than 70 decibels, then if your phone volume does not reach this decibel or more, it is likely to cause you to not hear or hear clearly, so that you miss some important information or calls. Next, let's look at the results of a test done by GSMArena. Obviously, ordinary smartphones are not able to meet the needs of this group of people for the volume.  In addition, loudest speaker can have a broader use, for example, in the morning you have difficulty getting up, but you have to go to work, you have to go hunting, you have an appointment with friends to go out, especially in winter, wrapped in the blanket feeling really too cozy, ordinary alarm clock and can not wake you up, you begin to hesitate in the wake and continue to lie in bed, you begin to think about whether to change the plan, this time, At this time, if the ordinary alarm clock is replaced by a loud speaker, you will not hesitate to get up, as long as the sound is sounded, you are stimulated, you will quickly jump up from the bed to turn off the sound, this time your sleepiness is completely gone, maybe with the loud speaker, it will not become so difficult to get up. In some extreme cases, smartphone with loudest speaker can even save your life, for example, you are trapped in a place, you need to shout for help, but your voice is too small, and only a few shouts, your throat is dumb, this time, with the power of the loud speaker, may be able to increase your chances of being rescued.  The smartphone with loud speaker is really practical, try to use the loud speaker phone to bring more surprises to your life.

Because of its function and appearance, people have always associated smartphones with young people and rugged phones with old people, but now more and more young people are choosing to use rugged phones.Why is that?I think the most important point is that we are dominated by all kinds of apps, smartphone can install all kinds of apps, but rugged phone only has the most basic functions such as making phone calls and sending text messages due to the limitation of technical conditions. This limits people's access to a wider online world to the greatest extent.I'm a 27 year old, I'm currently using an iphone 8, but I really want to change my phone, I want to try rugged phone, the next is my personal experience, maybe not universal, but somewhat representative.It's really rare for me to be able to spend a continuous hour doing something without being disturbed by other messages. When I'm working, I get messages from people on social media, and work groups often have message alerts, and even though they may not have anything to do with me at all, I still need to take the time to read them. Outside of work hours, my time is more fragmented. One minute I browse through the answers on Quora, one minute I chat with my friends on WhatsApp, one minute I browse on Facebook, one minute I browse shopping sites to see if there is anything I can buy, then I play games, then I browse Tinder to see if there are someone who has hooked up with me, and so on. I seem to be really busy, I have multiple apps to browse, but when I'm done, it's like I'm not browsing anything, but my time is passing while I'm switching between apps. The problem is, I don't get any information that helps me, I don't remember anything, and sometimes I even get some spam and I want to say what the fuck, I've been receiving information passively and I never have a choice about what I want to receive. Wait, I get it, all these seem to be social media apps.But I have to admit that there are some tool apps that are essential, personally, like Google Map, like Uber, like Airbnb, that really have made my travels easier.So to be precise, my life has become more convenient because of tool apps, but also more fragmented and meaningless because of various social media apps.So, at the moment I have two options, first, buy a smartphone, but only download some necessary tools, but as a human, I want to socialize, can I resist not downloading any social media apps? Instantly, I know that once I download this type of app, my time will definitely be divided. The other option is to buy a rugged phone, whether it's a social app or a tool app, I can't download it. I seem to be relearning how to live without my smartphone.

Infrared thermal imaging technology is a passive, non-contact detection and identification technology, can use the target and the background or between the target parts of the temperature difference or radiation differences in the formation of infrared radiation characteristics of the image to find and identify the target, its two basic functions are temperature measurement and night vision.Thermal imaging camera works on the principle of thermal infrared imaging technology. Modern thermal imaging devices work in the mid-infrared region (wavelength 3 ~ 5um) or far-infrared region (wavelength 8 ~ 12um). By detecting the infrared radiation emitted by an object, the thermal imager produces a real-time image, thus providing a kind of thermal image of the scene. Its core is a thermal imaging camera, which is a sensor capable of detecting very small temperature differences, the temperature difference into a real-time video image display. But only see the thermal corridor of people and objects, can not see the real face of the object. Advantages 1, day and night can be used normally 2, extreme weather can be used 3, can see through the fog, rain, smoke and other obstacles 4, all heat-generating objects are nowhere to hide in nature as long as the object above absolute zero (-273 ℃), will be constantly outward radiation of infrared. Thermal imaging that is through the optical system, infrared detector chip and electronic processing system, the object surface infrared radiation into a visible image. Simply put, the principle of thermal imaging is to use temperature imaging to transform the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.Thermal imaging is not affected by visible light, can be 24 hours clear imaging, non-contact temperature measurement, through the smoke and fog and other advantages, can be applied to human temperature measurement, industrial temperature measurement, automatic driving, security fire, outdoor observation, etc.. Commonly speaking, thermal imaging camera is the invisible infrared energy emitted by the object into a visible thermal image. The different colors on the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heat generation of the target can be studied to provide a basis for work and research. For example, the infrared thermal imaging camera can check the floor heating leakage, can accurately detect the indoor pipe network, such as the distribution and direction of the location of the floor heating pipes, water pipes, hot water pipes, and can accurately locate the location of pipe leakage. Underfloor heating leaks often exist in two phenomena.1. fuzzy diffusion of pipes at the leaky location, the storage of non-linear, presenting a cloud of heat in the infrared picture.2, the leak location temperature is high, in the infrared picture presents a white bright color.The main performance indicators of thermal imaging night vision device classification. 1. resolution: resolution is the assortment of thermal imaging night vision device is an important indicator, night vision device affects the cost of thermal imaging night vision device one of the keys. General thermal imaging night vision camera resolution of 160x120, 336x256 and 640x480 three. The selling price from tens of thousands to hundreds of thousands of dollars.2. the resolution of the built-in screen: we observe the target through the thermal imaging night vision device, in essence, is to observe its internal LCD screen. The top thermal imaging night vision device, its built-in screen resolution and clarity are very high, so that it is clearer observation effect and better vision.3. magnification: due to the technical bottleneck, the physical magnification of the thermal imaging night vision device, at present, the largest magnification can be produced for 5 times. 4. double tube or single tube: double tube in the use of comfort and observation effect are obviously far better than single tube, of course, the price of double tube thermal imaging night vision device will be much higher than the single tube thermal imaging night vision device, double tube thermal imaging night vision device in the production technology will be much higher than the single tube.

Recently, a friend came to me complaining that his recently purchased cell phone screen was broken, coincidentally, he did not buy a broken screen insurance, and eventually spent a lot of money to replace the screen. I was thinking that if my friend had bought a Rugged Smartphone, there would not be such a problem, but why has the Rugged Smartphone, which is waterproof, dustproof and shockproof, not been popular? Why is it only a niche category in smartphones? Why only a specific group of people will use this type of phone, such as construction workers, hunters, outdoor enthusiasts, etc.?First of all, people's impression of Rugged Phone is still stuck in a very long time ago, when talking about Rugged Phone, the first image that comes to many people's mind is Nokia 3310, which is indeed a kind of Rugged Phone, more precisely it is a feature phone, don't forget, there is also Rugged Smartphone. You can understand the Rugged Smartphone in this way, it combines the indestructibility of a feature phone with the intelligence of a smartphone.The second is that it is not as good-looking and light as ordinary smartphones. The fact that the Rugged Smartphone does not look good is not entirely the fault of the designer, but a major reason is the limitation of engineering materials. Today, the phone to do waterproof and dustproof is not a difficult task. To achieve this goal, there are usually two options. One is by reducing the splicing of the body, and then use the waterproof tape and seal to block the body gaps, making the body waterproof, dustproof ability greatly increased. This is the idea of structural dust and water resistance. This sealing method also has many drawbacks, such as headphone holes, charging holes on the rubber plug deformation, it will destroy the phone's sealing, resulting in a decline in the ability to waterproof and dustproof. This will require the use of nano-waterproof technology. Simply put, the device surface is coated with a layer of nano-polymer, liquid and coating contact will condense into water droplets rolled off, so if there is liquid into the device, you can quickly discharge. For rugged smartphone, these two options will basically be used at the same time. In the body of the charging hole, headphone hole parts of the rubber plug, although waterproof, mud-proof, but pulled down the body of the sense of sophistication. Another reason to reduce the beauty of Rugged Smartphone is the thick bezel. In order to prevent falls, rugged smartphone mostly use armor-type protective structure, the bezel is made thick and large, and the material mostly uses soft rubber to improve the toughness. Finally, the rugged smartphone currently have some features that may not be particularly practical for many people, for example, thermal imaging camera, loud speaker, accurate coordinate positioning in the absence of card and no signal, these technologies may only used by a specific group of people.I think these are the main reasons for the Rugged phone is not so mainstream, what do you think?

First, we need to know what extreme cold is. According to the Department of Emergency Management and Safety Services, extreme cold can be considered any temperature below the freezing point (32 degrees Fahrenheit).When the temperature drops low enough, you'll notice all sorts of problems with your phone: Sluggish response! Crazy battery drops! Dead phone! It simply shuts down! At this point you think it's the quality of the phone that's at fault, but in reality you don't know it's the low temperature that's to blame.Smartphones are generally installed with lithium batteries, which work on the principle that the internal electrolyte through a chemical reaction, the formation of potential differences, thereby generating current. In low temperature environment, the chemical reaction of lithium battery slows down, so the discharge current becomes smaller and the power drops. And when the phone turns on the battery low temperature protection, there may be automatic shutdown phenomenon. The iPhone has a clear statement on the official website that the normal operating temperature is 0~35℃; the best use temperature is 22℃; and the limit temperature is -20~45℃. Of course, we know that iPhone work less than normal when they are close to about 0℃! So, what about Android phones? In fact, it is similar. So in winter time, or colder areas, the use of cell phones can easily cause problems, and in some more extreme cases, your life will be threatened. For example, snow climbing, you encounter some special situation, you have to seek help, if you bring a normal phone, it is likely to automatically shut down long ago, so in similar situations, we need an unusual phone, this phone needs to be able to maintain normal operation even in extreme cold conditions. This unusual phone is the AGM Glory Pro, I am proud to say that with AGM Cold Resistant Battery, the phone can be used continuously for 22 hours at -27°C, 10 hours at -30°C and one hour at -40°C.Why is AGM Cold Resistant Battery unusual?1, Heat Protection SystemWith the redesigned structure, Glory will prevent heat evacuation under cold environments. All generated heat will be delivered across the components, boosting the cold resistance of the inner structure. 2, AGM Battery ActivationThe vitality of any lithium battery will decay under extreme coldness, with the AGM Battery Activation Solution, Glory's lithium battery will remain vital under -27°C. Proven by the Thermal Shock Test, AGM Glory is also adaptive to 60°C and other tough situations.

I have done a user research before, mentioning "what do you think of when you hear rugged phone", I was surprised that many people mentioned Nokia 3310, the research address is as follows, https://bit.ly/3A5OV8S, This is indeed a model of rugged phone, we can devide rugged phone into 2 categories, feature phone and rugged smartphone. The rugged smartphone has been developed over a long period of time, and now its functions are more powerful than those of ordinary smartphones. I can say this, as far as the function is concerned, rugged smartphone can completely replace the ordinary smartphone, but the ordinary smartphone can never replace the rugged smartphone.AGM is a professional manufacturer of rugged smartphones, I'll take AGM Glory Pro as an example. The following features are not available on ordinary smartphones. Glory Pro is IP68/IP69k/MIL-STD-810H certifiedThe IP Code denotes the degree of protection provided by your device's internal casings and enclosures against dust, intrusion, and most importantly water. IP68-rated machine can go up to 1.5m for the same amount of time, IP69k means that the phone would be able to withstand high-pressure, high-temperature jet sprays, steam-cleaning, or washdowns. Arctic Battery/ Cold Resistent BatteryThe Glory Pro can be used continuously for 22 hours at -27 degrees Fahrenheit, which is a very powerful feature. In more extreme conditions, many phones will fail, but not the Glory Pro.Thermal Imaging TechnologyAGM Glory Pro phone thermal imaging technology is the industry's top, with twice the resolution and 1/2of the reaction time than the best phone thermal imaging in the market.Measures all objects within 5 meters.Industrial Mode Accuracy: ± 2.0°C, ranging from rather -20°C ~ 150°C, or 100°C ~ 550°C.I just gave a few examples, there are many other features that are not available in a normal smartphone. If you want to know more, you can come to our website and have a look.

This is a screenshot I took from our website.There are a lot of words on it that people who are not in the professional field may not necessarily understand, so that they don't know how to pick the right phone for them. Next, AGM Mobile will explain these similar proper nouns from a professional perspective so that you can pick the right phone for you.1, What is Qualcomm Snapdragon?Qualcomm Snapdragon is a processor, and many people know that the processor is the core of the phone. Now the high-end processors are Snapdragon 865, Apple A13, Kirin 990, etc., while the mid-range processors are Snapdragon 7 series, Kirin 820 and other processors. The better the processor of the phone, in general, the more smooth the phone. But the better the processor, the greater the corresponding power consumption, the phone is easy to heat up.2, IP68/IP69K/ What does it mean?Here IP is the abbreviation of Ingress Protection, the IP Code denotes the degree of protection provided by your device's internal casings and enclosures The IP Code denotes the degree of protection provided by your device's internal casings and enclosures against dust, intrusion, and most importantly water.As per IEC standard 60529, IP is always succeeded by two digits. If we take IP68 as an example, the first digit (tens), 6, denotes protection against dust, If we take IP68 as an example, the first digit (tens), 6, denotes protection against dust, while the second digit (units) signifies protection against prolonged immersion in water.For a detailed guide, have a look at this picture:So IP68-rated machine can go up to 1.5m for the same amount of time, IP69k means that the phone would be able to withstand high-pressure, high-temperature jet sprays, steam-cleaning, or washdowns.
