A rookie who just graduated now works in a property company and needs patrol products for security. I don't know them very well. Look for it on the internet.

Well, that's all right. There are still quite a few styles of cloud products launched now. Cloud patrol is a new generation of ready-to-use electronic patrol, which uses both WiFi and GPRS communication networks. It has the characteristics of no traditional server, no computer, no software installation, real-time data uploading and viewing anytime and anywhere, which makes administrators and users more worry-free. I hope it helps you.
