The cover and defense device are the two core components in the safety protection system, each responsible for important protective duties. As a passive protective device, the main function of a cover is to cover or wrap key components, effectively isolating harmful factors such as dust, moisture, and chemicals in the external environment, and preventing damage to internal systems. It is usually made of high-strength and corrosion-resistant materials, with a focus on practicality and durability in design. Some covers also have quick disassembly and assembly functions, making it easy for daily maintenance and repair. Defenders, on the other hand, are more proactive security protection devices that use various technological means such as physical barriers, electronic monitoring, and intelligent recognition to monitor and resist potential threats in real time, ensuring the safety of personnel, property, or systems is not violated. The defender can automatically identify abnormal intruders, trigger alarms or take corresponding defense measures, improving the intelligence level and response speed of security protection.
