"Wearable devices" are now the most popular fried chicken in the investment community. The industry generally believes that wearable devices will become the "fourth screen" after TV, PC, and mobile phones. According to market research firm Canalys, in 2014, 8 million smart bracelets will be sold globally, and by 2015, sales figures will increase to 23 million. By 2017, sales volume is likely to exceed 45 million, when the global market will be Sales will reach $15.5 billion. iResearch expects that China's wearable device market will reach 40 million units in 2015, and the market size will reach 11.49 billion yuan.
Although "wearable devices" suddenly entered the public eye, it is actually nothing new. Many products in the medical world are the most mature branches of wearable devices, and can be traced to heart pacemakers and heart stents. With the concept of "wearable devices" being popular, traditional medical devices such as Bao Laite, David Medical , and Jiu'an Medical are actively testing wearable devices in the sense of the Internet of Things. Evidence-based medicine technology company also has a very mature health watch development technology. The evidence-based watch has independent call function, activity location record, connection sphygmomanometer, blood glucose meter, global precision WI-FI indoor positioning connection weight body Meter, ECG.
In fact, the Internet of Things industry generally believes that the medical and health field will become the first big opportunity for wearable devices, and wearable devices will also reshape the industrial structure in the medical device field. Wearable devices are posing a major challenge to the medical industry . In the future, diagnostics, monitoring, treatment, and drug delivery will all be fully intelligent. Summarizing the investment dynamics in 2014, investments in wearable devices are increasingly concentrated in the health care sector. In March of this year, the mobile health startup "37 Health" received 10 million yuan in the angel round financing, and its product is the blood pressure butler APP. 37 Health is working with several sphygmomanometer manufacturers in China to try to establish a “soft + hard†business model.
Why do all companies that make wearable devices choose health as an entry point? On the one hand, medical health problems have always been a pain point for Chinese people. The aging is increasing, the number of sub-healthy people is increasing, and the mobility of the population is rising. All of them make healthy wearable devices a must for many Chinese. They need to know the family's body in real time. On the other hand, traditional medical care has many shortcomings and limitations. Healthy wearable devices present very obvious market opportunities and business models, which will make health demand the number one in wearable devices for the foreseeable future. Hot areas.
Compared with smart watches, smart bracelets, etc., everyone can have, but everyone does not have to have products, the main health wearable devices are undoubtedly more clearly positioned, more touching the user's pain points. Especially when people are sick or physically uncomfortable, users' attention to health is unprecedented, and wearable devices with health needs are more likely to impress users. For a long time to come, wearables will still be an accessory to mobile phones.
In the final analysis, healthy wearable devices must go out of the elite circle. In addition to further optimizing the user experience and improving data quality, the most important thing is to truly solve the user's health needs. Users insist on using healthy wearable devices because they have specific health needs, rather than being touched by the notion of “sports socialâ€, “cloud healthâ€, “soft and hard†and other small circles. Of course, even Fitbit and Jawbone have not really proved their success in the commercial sense. Health wearable devices are still at a very early stage in China, and there is still a long way to go in the future.
The Digital Video Recorder, also called the DVR/ DVR Security System/ DVR monitor/Digital Video Recorder H.264/ DVR CCTV, is the video storage device of the AHD Four in One Camera(the video capture device). The Digital Video Recorder records the video with the hard disk that we put in it, and it is a computer system for image storage and processing, which has the functions of long-term image recording, voice recording, remote monitoring and control of images/voices.
The Digital Video Recorder is far superior to the analog monitoring equipment in terms of the image processing, image storage, retrieval, backup, network transmission, and remote control because of the adoption of the digital recording technology.
By the way, there are many BNC video interfaces on the back of the Digital Video Recorder, each interface can be connected to an analog suveillance camera. Just plug the interface, then it works, very convenient!
Generally speaking, the Digital Video Recorder can be divided into the hard disk video recorder, the PC type hard disk video recorder and the embedded hard disk video recorder, etc. Among them, the embedded hard disk video recorder does well in the stablity, the reliability, and the easy use, and the embedded hard disk video recorder will gradually invade the market of the PC type hard disk video recorder.
Besides, The main functions of the Digital Video Recorder include: monitoring function, recording function, playback function, alarm function, control function, network function, password authorization function and work schedule function.
Monitoring function: The monitoring function is one of the most important functions of the Digital Video Recorder. Whether it can monitor the on-site camera video clearly is a core issue of the surveillance system. Most Digital Video Recorders can achieve clear on-site surveillance.
Recording function: The video resolution is the core of the digital host because the video effect is more important to the Forensics than the on-site video effect. Most Digital Video Recorder can achieve on-site recording at 25 frames per second.
Alarm function: The alarm function mainly includes the input alarm of the detector and the alarm of the image and video detection. Once received the alarm signal, the system will automatically start recording, and turn on the corresponding spotlight, siren and network output signal via the alarm output function. The image motion detection is the main alarm function of the Digital Video Recorder.
Control function: The control function refers to the omnidirectional control of the PTZ and lens via the host, which is generally finished by the dedicated decoder and the keyboard.
Network function: The user can do various operations to the host such as the monitoring, recording and control after the simple identification on the LAN or WAN, which is similar to the local opertaion.
Password authorization function: in order to reduce the failure rate of the system and illegal entry, a password need to be set for procedures such as stopping video recording, arming and disarming the system and entering programming, so that unauthorized people cannot operate these procedures. The Password authorization is usually set as the multi-level password authorizations.
Work Schedule function: The user can program the working time for one certain period of time of one certain camera, which is also the unique function of the host of the Digital Video Recorder. The user can pre-schedule all the changes of holidays and working schedules into the program, which can realize the unattended in some extence.
All in all, the Digital Video Recorder represents the developing direction of CCTV monitoring system and it has been the first choice on the CCTV monitoring system market.
