  • FAQs about Door & Window Alarms

    Are window alarm sensors worth it?

    Yes, home window alarm sensors are worth it for enhancing home security. They provide an extra layer of protection by alerting you to unauthorized entry through windows—one of the most common break-in points. Affordable, easy to install, and often compatible with smart home systems, eufy window alarm sensors offer valuable peace of mind at a relatively low cost

    What are the different types of window alarm sensors?

    Window security sensors come in mainly three types, including:
    Contact Sensors: They detect when a window is opened or closed.
    Glass Break Sensors: They trigger an alarm when detecting the sound of breaking glass.
    Motion Sensors: These sensors detect movement near windows.

    Where do you put a window alarm sensor?

    A window alarm sensor should be placed on or near the window frame where the sash meets the sill or frame when closed. Typically, the sensor has two parts: one on the window and one on the frame. They must align closely so the system can detect when the window is opened or tampered with.

    How much do window sensors cost?

    Window sensors typically cost between $10 and $40 each, depending on the brand, features, and whether they’re part of a larger security system. For example, eufy offers many smart window sensors under $30, ensuring cost-effective and reliable protection for your home.

    Do window alarms deter burglars?

    Yes. Window alarms are highly effective deterrents against burglars by emitting a loud siren, sometimes reaching up to 100 dB, which startles intruders and draws attention. The sudden noise and alert can discourage further criminal activity, ensuring a rapid response from homeowners or security services and ultimately contributing to a safer home environment.
