With the increasing maturity of digital video compression encoding technology and the popularization of microcomputers, conditions have been created for PC based multimedia monitoring. The multimedia monitoring system based on PC has strong functions, but mainly solves the problem of small-scale monitoring. When the transmission distance is long or internet access is required, PC based multimedia monitoring has poor stability, high power consumption, the need for someone to be on duty, and poor software openness. This provides a stage for network video surveillance based on network and embedded technology.

Explosion proof cameras cannot be considered a new variety. They are just an upgraded version of ordinary cameras used in special engineering applications to achieve more reasonable performance in camera materials. They can also be called high security cameras, impact resistant cameras, impact resistant cameras, or non-destructive cameras. Replacing traditional cameras is inevitable and has become the mainstream of cameras. Camera manufacturers have advantages in image quality and color reproduction, and can use some of their past camera technologies. However, they are at a disadvantage in video compression, monitoring software, and backend supporting equipment and technology, making it difficult for them to become the main players in the future market.

The explosion-proof camera integrates a regular camera and a network converter to convert images into data packets based on TCP/IP network standards, allowing the images captured by the camera to be directly transmitted to the network through an RJ-45 Ethernet interface. Remote monitoring of the screen can be achieved through the network.

Riot cameras are cameras that can still ensure the normal operation of components under external violent attacks, and their characteristic is that their shells have strong impact resistance. And this kind of situation is more common in places where violent emergencies occur, unmanned environments, complex personnel, and high pedestrian flow occur. Of course, it also includes places where natural phenomena such as typhoons and hail often cause damage to cameras due to the presence of hard objects.

The application of riot cameras is not limited to ATM machines and surveillance cameras, such as public security bureaus, courts, stations, subways, 24-hour convenience stores, etc., which are all likely to become malicious targets of criminals. In fact, riot cameras should be used in all areas.
