At the end of 2019, a pneumonia caused by a novel coronavirus (2019-nCoV) emerged in Wuhan. In the early days of 2020, it spread across China, carried by the Spring Festival travel rush, through human-to-human transmission. Currently, the number of confirmed cases of novel coronavirus pneumonia has exceeded tens of thousands, and the World Health Organization has declared the novel coronavirus outbreak a public health emergency of international concern. The battle against the novel coronavirus has entered a critical period!

       The pandemic has made the panic and fear felt by people increasingly evident. Staying at home has become the key word for this year's Spring Festival. However, while in a state of panic, we can clearly see that security technologies, including security emergency deployment and control, are helping China gradually overcome the "battle against the epidemic" of COVID-19.

       Controlling the epidemic through prevention and isolation, and implementing isolation and monitoring for key areas, are the key measures currently used to control the spread of the epidemic. Installing surveillance cameras in key areas of communities and rural areas is an effective measure for grassroots epidemic prevention. At present, many enterprises are providing monitoring technical services to the government, further reducing the government's costs and expanding the monitoring scope, demonstrating their responsibility and commitment in epidemic prevention and control.

       In rural areas, cameras with high-definition, all-round monitoring and video replay functions can assist village and branch committees in effectively carrying out tasks such as managing visits from strangers, monitoring villagers' movements when they are away, allowing outsiders to enter the village, and rechecking personnel flows. This has improved the efficiency of epidemic prevention and control. By extending security prevention measures to the villagers' vicinity, a "combination of human defense, material defense, and technological defense" security prevention system has been formed.

       In response to the rapidly developing epidemic situation, it is of great significance to be able to respond promptly and implement strict control measures quickly. Some of the blocked intersections are temporarily controlled. To reduce on-site personnel duty and quickly set up a video monitoring system plays an important role. Our company's 4G intelligent multi-functional emergency control ball TQ-7730MM has several advantages such as convenient installation, quick use, and no need for wiring. By using the monitoring situation on site, it can be controlled using a tripod, or it can be hoisted using platforms, lamp posts, etc. The bottom of the control ball also has magnets that can adhere to metal objects. It has a built-in battery and can be used immediately upon startup. This brings great convenience to epidemic monitoring.
