During the National Congress of the 2018, the "channel" in the Great Hall of the People attracted the attention of all walks of life.
On the basis of the traditional “Ministerial Channelâ€, this year’s “representative channel†and “committee channel†have been added. Here is a window for debut and display. On this year's "representative channel" and "members' passage", these representatives and members also brought these objects while answering reporters' questions.
Qiu Hushan, member of the Chinese People's Political Consultative Conference and the chief physician of the Fuwai Hospital, and the secretary-general of the Chinese Society of Cardiothoracic Anesthesia, said that he had participated in the rescue of a acquaintance and saw that life was passing in front of his own eyes. He said that one person in China has a heart problem every minute, but only 1% of people in China have cardiopulmonary resuscitation, and 60% in the United States. To this end, he called on the state to pay attention to this skill development.
Yan Hushan patted his own defibrillator and said, "In particular, you must learn the defibrillator, this is a life-saving artifact." It can significantly improve the rate of life treatment. Regrettably, the current defibrillators are not common in China's Beijing, Shanghai, Guangzhou and other major cities. I hope the media will strengthen the propaganda of defibrillators.

Does the solar PTZ Camera System Kits work well
In fact, there are no network and no electricity cameras, but they have certain limitations. The working time of a camera with batteries or external solar panels is limited.Monitoring without network means that mobile phones and cameras can only be seen within a certain range of 5~10 meters.
Therefore, no network and no power is just a gimmick. We must pay attention to distinguish when buying.
Is the Solar Camera easy to use
Jiajie intelligent surveillance camera is very good
Advantages and disadvantages of solar monitoring
Probably.
Generally, offline display has the following two conditions.
One is that the installed 4G card has no traffic and cannot provide network connection for monitoring;
The other is that there is a problem with the signal receiving device, which makes it unable to connect to the network. Therefore, the user can access the APP connected to the monitor to check whether there is still traffic on the 4G card. If there is still traffic, there is a problem with the monitoring; If there is no traffic, the renewal fee can continue to be used.
Which is the best solar Outdoor Camera
It may be that the poor contact of the power plug causes power on, heating and power failure, or it may be that the camera's internal control motherboard fails, causing power on for several minutes and automatic power off protection.
The camera works continuously, and the internal chip may overheat, which also exists in many SLR cameras. Some cameras impose time limits on continuous shooting. Centralized power supply with high-power switching power supply
Disadvantages of camera solar power supply
The main advantages of solar photovoltaic power generation are:
(1) Simple structure, small and light volume;
(2) Easy to install, easy to transport, short construction period, and short time to obtain energy;
(3) It is easy to use and maintain, and can work normally in the temperature range of - 50 ℃~- 65 ℃;
(4) Safe, reliable, noiseless, pollution-free, and absolutely clean (pollution-free);
(5) The advantages of building roofs can be used without the restriction of resource distribution regions; For example, areas without electricity and areas with complex terrain;
(6) The rate of price reduction is fast, and the time for energy repayment may be shortened;
(7) It can be matched with the battery to form an independent power supply, or it can be connected to the grid for power generation.
(8) Local power generation and supply without fuel consumption and transmission lines
The main disadvantages of solar photovoltaic power generation are:
(1) Low solar energy density and large coverage area;
(2) Photovoltaic power generation is intermittent and random;
(3) Solar energy resources in various regions are not available, so photovoltaic power generation is highly regional.
