Smart Home Security Alarm Hub Kit — Doorbell Mode, Sound Function, Remote Control, Easy Setup

Use the hub as a doorbell to consolidate controls and cut down on multiple apps — Doorbell Mode turns the system into a single, convenient entry alert. Volume is fully adjustable across levels 0-15 so you can set the alarm sound to suit your environment. Schedule automatic arming and disarming with a timetable feature to avoid repeating daily actions or forgetting to secure the system. The hub supports intelligent linkage for varied scenarios and automation. It can learn up to 4 remote controls and connect with as many as 50 wireless detectors, giving flexible expansion and simple remote operation.
