Home alarm systems — Wi-Fi and GSM kits with hub, sensors, siren and app control.
A home alarm system protects homes, flats, shops and offices with a loud siren and instant alerts when a door opens or motion is detected. Wi-Fi alarm kits send notifications to a phone app, while GSM alarms use a SIM card to send text messages and calls, which keeps working if the internet goes down. A typical kit includes a control hub, door and window sensors, PIR motion detectors, remote key fobs and a siren, and more sensors can be added later. Check the communication method, number of supported sensors, battery backup and app compatibility before ordering. Pet-immune motion sensors reduce false alarms from dogs and cats. Wireless sensors make installation quick without drilling for cables.
Sensors: door/window alarms.
