Door & Window Alarm Sensor

Yes, the door security alarm sensors typically have batteries that power their functionality and ensure continuous operation even in case of power outages. For example, eufy's front door entry sensors provide monitoring for 730 days with the included battery.

A door and window alarm sensor works by using magnetic or motion-sensing technology to detect when a door/window is opened or closed. When the door/window is opened, the sensor's components trigger a signal that communicates with the alarm system, causing it to activate an alert, such as a sound or notification, to indicate the breach of the door and window security.

An alarm sensor on a door is typically placed near the door frame, with one part attached to the door itself and the other part attached to the door frame. These two components should align closely when the door is closed, allowing the sensor to detect the door's movement, whether it's opening or closing, and trigger an alarm if the door is breached.

A motion sensor and a door sensor serve different security purposes. A motion sensor alarm detects movement within a space by sensing heat or infrared radiation changes, making it ideal for monitoring wide areas such as living rooms or hallways. If unexpected motion is detected, it triggers an alert. On the other hand, a door or window alarm sensor is designed to track the open/closed status of specific entry points. It immediately notifies you if a door or window is opened unexpectedly, ensuring key access points remain secure.

This depends on the number of entry points you want to secure. It's recommended to place a door security alarm sensor on each external door, including front, back, and side doors. For added protection, install window alarm sensors on ground-level or easily accessible windows. If you also use motion sensor cameras with continuous recording, you may reduce the number of sensors needed while still covering larger spaces.

Yes, eufy's door and window alarm sensors are designed for simple DIY installation. Most models come with adhesive pads or screws, allowing you to attach the sensors to doors or windows without professional help. The setup process is straightforward, and the sensors pair quickly with eufy Security app for monitoring and notifications.

The detection range depends. Most eufy wireless door sensors reliably communicate within 30 metres of the base station or hub indoors. Walls, metal surfaces, and other obstacles may slightly reduce the effective range, so positioning the smart home hub centrally can improve connectivity.

Yes, our window alarm sensors are designed to send push notifications to your mobile device almost instantly whenever a window is opened. This allows you to monitor your home security system in real time, providing peace of mind even when you’re away. Notifications are fast and reliable, especially when the sensor is paired with a strong Wi-Fi connection.
