Broadlink Door Sensor SR4D
Smart Entry Detection for a Safer- Smarter Home
The Broadlink SR4D Door Sensor is a compact- intelligent device designed to notify you whenever a door or window is opened or closed. As part of the Broadlink smart home ecosystem- it enables real-time monitoring and automated security responses to protect your property- enhance convenience- and support energy efficiency.
Whether used on your front door- balcony- window- or office cabinet- the SR4D is your silent guardian — always watching- always alert.
Real-Time Open/Close Status Alerts
Once installed- the SR4D continuously monitors the status of any door or window. When triggered- it sends immediate notifications to your smartphone via the Broadlink app- so you’re always aware of activity at home — even while you’re away.
It enhances home security by helping detect unauthorized entry or forgetfulness (like an open fridge door).
Seamless Smart Home Automation
Paired with other Broadlink smart devices- the SR4D can trigger automation rules — such as turning on lights when a door is opened- or turning off the air conditioner if a window is left open. This automation saves energy- enhances comfort- and makes your environment smarter.
It’s also compatible with voice assistants like Alexa and Google Assistant through the Broadlink ecosystem.
Compact- Wireless Design
The SR4D sensor features a slim- wireless design that fits discreetly on most doors and window frames. It’s battery-powered- eliminating messy wires- and installs easily with adhesive backing — no drilling required.
An LED indicator shows the sensor’s status for easy setup and diagnostics.
Long Battery Life & Low Power Alert
Designed for longevity- the sensor uses low-energy wireless transmission and has a long-lasting battery. The Broadlink app will alert you when the battery is low- so you’re never left unprotected.
