门禁系统安全性
Security of access control system
门禁及安防系统是用来保护人员和财产安全的，因此系统自身必须安全。这里所说的高安全性，一方面是指产品或系统的自然属性或准自然属性，应该保证设备、系统运行的安全和操作者的安全，例如：设备和系统本身要能防高温、低温、温热、烟雾、霉菌、雨淋，并能防辐射、防电磁干扰（电磁兼容性）、防冲击、防碰撞、防跌落等，设备和系统的运行安全还包括防火、防雷击、防爆、防触电等；另一方面，门禁及安防系统还应具有防人为破坏的功能，如：具有防破坏的保护壳体，以及具有防拆报警、防短路和开路等。
Access control and security system is used to protect personnel and property safety, so the system itself must be safe. The high safety mentioned here, on the one hand, refers to the natural or quasi natural attributes of the product or system, which should ensure the safety of equipment and system operation and the safety of operators. For example, the equipment and system itself should be able to prevent high temperature, low temperature, warm heat, smoke, mold, rain, radiation, electromagnetic interference (electromagnetic compatibility), impact, collision, fall, etc The operation safety of the equipment and system also includes fire prevention, lightning protection, explosion-proof, electric shock prevention, etc.; on the other hand, the access control and security system should also have the function of preventing man-made damage, such as the protection shell against damage, the anti disassembly alarm, anti short circuit and open circuit, etc.
