The price is preferential, the customer service is average, after all, the factory store, their normal commuting is different from the general customer service, but they will reply. There is not much difference from the description, it is said that it has an anti-interference effect, and I don't know if it will work if it is installed... Hey, the psychological comfort effect may be greater! I will buy it again! The price is half cheaper than Taobao, and the freight is included in it, a conscientious manufacturer! The delivery speed is very fast, the wire core is very thick, all copper wire, although it is a loose wire, it has been tested before leaving the factory, that is, the manual sent by the factory cannot be understood, I still asked the professionals to know how to do it! A must-have for installing a camera at home after the year!!
