进口的控制器在产品的稳定性和成熟性都是很好的。不过价格昂贵，而且由于地域的差距，服务的及时性会不好，而且服务成本偏高。同时，由于文化背景的差异，国外用户对出入管理控制的需求和要求和中国的国情是有区别的，很多功能根本不适合中国国情和中国用户的需求。
The imported controllers have good stability and maturity. However, the price is expensive, and due to geographical disparities, the timeliness of service will be poor, and the cost of service is high. At the same time, due to the difference of cultural background, the demand and requirement of foreign users for access control are different from China's national conditions. Many functions are not suitable for China's national conditions and the needs of Chinese users.
当然，中国很多门禁控制器厂家生产规模小，设计能力弱，成功应用案例少，工程商也宜慎重选择。中国很多门禁控制器厂家，为了推销河北立体车库 消防报警器塑料配件 电缆接地箱 电缆保护接地箱 塑料土工格栅 消弧线圈装置 自己的产品，打着台湾、美国、加拿大等国家和地区制造的幌子进行欺骗性销售，其实产品品质有着很大问题，这个现象工程商也应该谨慎对待。
Of course, many entrance guard controller manufacturers in China have small production scale, weak design ability and few successful application cases, so engineers should choose carefully. Many entrance control manufacturers in China sell their products deceptively under the guise of manufacturing in Taiwan, the United States, Canada and other countries and regions in order to promote their products. In fact, the quality of products has a lot of problems. This phenomenon should also be treated with caution by engineers
