ALARM.COM INC.

小企业主和房主并非为硬件付费，而是为一个及时到达的信号付费——信号经设备、云端、经销商、监控中心到手机，足够快到改变结果。Alarm.com 的价值在于其重复性软件收益依赖于这条链条的可信度。

A small business owner does not pay each month for a motion sensor in the abstract, and a homeowner does not pay because a doorbell camera exists. The paid unit is a signal that moves from device to cloud, dealer support, monitoring workflow and phone screen quickly enough to change the outcome. Alarm.com matters because its recurring software margin depends on that fragile chain staying trusted while dealers, wireless carriers, camera hardware, cloud operations, apps, monitoring stations, DIY rivals and big smart-home ecosystems all compete for the same monthly account.
