Video surveillance system plays an important role in modern society. In order to ensure its normal operation and data security, the video monitoring host should be stored in the cabinet. Video surveillance host is the core component of the whole system, which is responsible for receiving, processing and storing surveillance video signals.
The cabinet can provide good protection and fixation. Cabinets are usually made of solid metal materials, which have protective functions and can resist external physical injuries to a certain extent. In addition, there are fixing brackets and fixing devices inside the cabinet, which can fix and protect the video surveillance host to prevent it from accidental collision or toppling.
The cabinet can provide good ventilation and heat dissipation. Video surveillance host will generate a lot of heat in the process of long-term work. If the heat can not be dissipated in time, it will lead to overheating of the equipment, further affecting its operational stability and life. Ventilation holes and fans are designed inside the cabinet, which can effectively discharge heat and keep the ambient temperature around the equipment suitable.
The role of video surveillance
1, providing higher security.
Shops, schools, bus stops and other places where video surveillance systems are installed can effectively reduce criminal activities and illegal acts. The existence of surveillance cameras can deter potential criminals and reduce the crime rate. It also helps to quickly detect and respond to emergencies, such as fire and theft. Through real-time observation of the monitoring screen, people can take timely measures to protect the safety of themselves and others.
2, can provide evidence to solve the dispute.
Monitoring video can record the real incident process, which is helpful to the investigation and analysis of accidents, disputes or criminal cases. As effective evidence, surveillance video can be provided to courts, police and insurance companies to help them make correct judgments and treatments. They can provide factual basis and prevent injustice and misunderstanding.
3. It is helpful for supervision and management.
The monitoring system can observe many places in real time in the remote monitoring room and supervise the behaviors of employees, students and visitors. It can help managers discover misconduct, employee absenteeism and monitor work progress in time. In addition, surveillance video can also be used to evaluate employees' performance and improve workflow and training plan. This management method can improve work efficiency and optimize resource allocation.
