This entry alert system is designed to provide a straightforward and reliable notification when a door is opened. The package includes two magnetic sensors and one receiver, allowing coverage of two separate entry points such as a front door, back door, or bedroom entrance. The wireless transmission range extends up to 500 feet in open areas, ensuring the receiver picks up the signal even when placed across a typical home or small office. The receiver features a selection of 58 different chime melodies and five adjustable volume levels, including a silent flashing indicator mode, so users can choose an alert that suits their environment without being disruptive. The construction of the sensors and receiver uses durable ABS plastic, which offers a decent level of impact resistance for everyday use. The magnetic contacts are housed in compact units that adhere to door frames and doors via double-sided tape or screws, depending on the surface material. The receiver plugs into a standard wall outlet, providing constant power without the need for frequent battery changes. The sensors themselves are powered by standard alkaline batteries (included), offering straightforward maintenance and long standby life. The overall build quality meets typical expectations for an affordable electronic accessory, with consistent molding and clean contact points.

Functionally, the system operates on a 433MHz radio frequency, which is common for such devices and provides stable signal transmission through walls and floors within the stated range. The sensors trigger the chime immediately upon the magnetic contact being separated, with a response delay that is barely noticeable. Users can set the receiver to a specific chime for each sensor, making it easy to distinguish which door is being opened. The volume range goes from a soft chime for quiet environments to a loud alert that can be heard across a larger space, suitable for homes with elderly individuals or for monitoring children or toddlers moving around. This product is intended for home use, small business offices, bedrooms, or any area where knowing when someone enters is helpful. It can assist in monitoring the movement of a family member with dementia or a curious toddler, providing an audible cue without requiring constant supervision. The affordable price point makes it an accessible option for those seeking a basic entry alert without unnecessary complexity. The two-sensor configuration offers flexibility for covering two different doors, while the receiver can be placed conveniently near a central area.

This entry alarm set delivers reliable performance for its category, focusing on essential functionality and ease of setup. The system maintains consistent operation under normal indoor conditions, and the magnetic sensors are rated for a gap of up to 1.5 inches between the two halves, allowing for some misalignment during installation. The receiver’s memory retains the selected chime and volume settings even after a power interruption, adding to the convenience. For users who prefer a more discreet alert, the LED flash mode provides a visual signal without sound, suitable for times when silence is required. The compact design of both sensors and receiver does not clutter the doorway or wall, blending into the surroundings modestly.
