With the emergence of Google Glass, wearable devices are one of the most popular smart products in the technology circle. When mobile medical met with wearable devices, a wave of subversion of the original health management model was on the rise. Although the current medical wearable devices on the market are only relatively simple devices such as smart bracelets and heart rate monitoring, medical wearable devices are considered to be beneficial because they can help people complete monitoring, medical treatment and cost savings without leaving home. Unlimited potential. Medical wearable devices are striking At present, the more common medical wearable devices have portable dynamic electrocardiograms for patients with heart disease, which can continuously record the whole process of 24-hour electrocardiogram activity. It can find arrhythmia and myocardial ischemia that are not easily found in conventional electrocardiogram, and increase the data. The timeliness of analysis and the long-lasting effect of the test, and the ability to complete the danger warning function; and the implantable blood glucose monitor for diabetic patients, it can not only monitor the blood glucose value in real time, but also implant the micro pump to release the drug. Another example is an electronic sphygmomanometer for hypertensive patients. To be more eye-catching, you have to mention that Google is developing a contact lens that measures blood sugar level sensors in tears; Apple is also trying to apply non-perceived blood detection technology to wearable smart devices. And the traditional minimally invasive implant sensor company Cardio-MEMS is developing a wireless device that can be implanted into the human body to control severe chronic cardiovascular diseases such as heart failure, aneurysm, and hypertension. The reason why wearable devices are in the medical field, Li Wei, a researcher at the Shenzhen Institute of Advanced Technology and the director of the Biomedical Information Technology Research Center of the Chinese Academy of Sciences, believes that this is because we have ushered in the era of sensing the external world and the environment. The age of self-awareness, especially the physical health of the self. Wearable devices such as Google Glass bring people an optional consumption that enhances the quality of life. In comparison, medical wearable devices meet the rigid needs of many people to some extent. As we all know, China has entered the high incidence of chronic diseases, with a large number of patients, high medical costs, long illness time and large service demand are the prominent features of this period. Reasonable management of chronic diseases can avoid emergency and hospitalization and reduce the number of medical treatments, which can greatly save costs and labor costs. In the "Dressable Health Medical In-depth Report" released earlier this year, GF Securities pointed out that in 2012 about 30 million wireless wearable health sensors were used in the medical electronics field, which is a 37% increase over 2011. According to ABI It is predicted that applications for remote patient monitoring and online professional medical care will account for 20% of the overall wearable wireless device market in 2017. According to BCC Research, the mobile medical market will grow from $9.8 billion in 2010 to 2015. The annual growth rate of $23 billion was 18.6%. Mobile medical support system However, medical wearable devices are not only dependent on reliable technology. In Li Wei's view, medical wearable devices or mobile medical implementations need to be supported by several aspects. The first is chip acquisition. The chip is regarded as the basis of the wearable device. Since it is necessary to wear it at all times, it is necessary to focus on the convenience, comfort and energy consumption of the user. Therefore, the chip mainly solves the technical problem of miniaturization and portability. Secondly, it is a cloud computing platform that supports heterogeneous medical information and a parallel analysis processing mode for massive health information. Technically speaking, the cloud computing platform mainly plays the role of collecting and sorting data. Li Wei said that the current cloud computing platform is still more used, such as Google's solution, the feasibility is not a problem. “The key is whether domestic companies can propose a disruptive cloud platform solution based on the characteristics of medical data.â€
In conclusion, we should correctly know about the 4K and the resolution, and choose the most suitable resolution when we buy a electric device, the DVR, the security monitoring device or something.

So what does 4K resolution mean?
In the digital technology field, people usually use the binary operations and the pixels to describe the size of the digital image. Due to the huge number of pixels that make up a digital image, the digital image size is usually represented by K. The 10th power of 2 is 1024, so: 1K=2^10=1024, 2K=2^11=2048, 4K=2^12=4096. How many 1024 pixels there are in the horizontal direction means how many K a video includes. Specifically speaking, for example, the resolution 2048×1080, 2048 represents the number of pixels in the horizontal direction and 1080 represents the number of pixels in the vertical direction; similarly, when the resolution is 4096×2160, 4096 represents the number of pixels in the horizontal direction, and 2160 represents the number of pixels in the vertical direction. In the actual production of alphanumeric version and digital projection, the number of pixels in the horizontal or vertical direction of the image needs to be adjusted according to different aspect ratios. Therefore, the resolution of 8847360 pixels close to the 4K image can also be called the 4K such as the resolution 3840*2160 which is common on the market. And strictly speaking, the standard 4K resolution is exactly 4 times the number of pixels of the 2K resolution 2048×1080, and 16 times the number of pixels of the 1K resolution 1024×540.
4K resolution belongs to the Ultra HD resolution, which means that the audience will be able to see every detail and close-up in the photos/videos at this 4K resolution. If 4K resolution is applied to the cinema, the audiencescan cearly see every detail and close-up of the film whichever cornor of the cinema they are at.
4K resolution refers to that the pixel value per line in the horizontal direction reaches or approaches 4096, regardless of the aspect ratio. 4K resolution also has a variety of derivative resolutions, such as the Full Aperture 4K(4096*3112), the Academy 4K(3656*2664), and the UHDTV 4K(3840*2160), etc.,. And in the security and protection field, when we mention the 4K resolution, it refers to 3860*2160, 800W pixels.
4K resolution fits the resolution standard of the new generation of the Hollywood blockbusters. Different from both the so-called high-definition TV (1920×1080 resolution)that we watch at home and the large 2K resolution screen (2048×1080 resolution) of the traditional digital cinema, the 4K resolution means the ultra-high resolution video of the 4096×2160 resolution. The traditional high-definition TV shows the video of 2.07 million pixels, the traditional digital cinema shows the video of 2.21 million pixels, while the 4096×2160 resolution theater can show the high-definition video of 8.85 million pixels.
The potential of medical wearable devices is not just technology
The DVR 4K,also called the Digital Video Recorder 4K/ Digital 4 Video Camera Recorder/ 4K DVR Security System/ 4K DVR CCTV/ 4K DVR Amazon, means that this DVR has the resolution of 4K.
