Wireless Motion Sensor Alarm System, 500-Foot Range

A missed visitor or unexpected movement in a back room is easy to overlook when you are away from the entrance. This wireless motion sensor system sends an alert to a receiver, so you can hear a chime or alarm from another spot in your home or business.

The receiver plugs into an outlet, while the sensor uses two included AAA batteries. It offers 58 ringtones and five volume levels, giving you room to choose a sound that suits the space. The receiver’s LED also flashes when it receives a signal.

Technical details

The stated wireless operating range between the sensor and receiver is up to 500 feet. The infrared sensor detects movement from about 13 to 16.5 feet away, with a 110-degree detection angle. The alarm is listed at 110 dB, and the receiver can be paired with up to 20 motion sensors. Those figures help set expectations, but placement and the layout between the units matter: a sensor’s detection area is not the same as the receiver’s wireless range.

There are two alert styles to consider within the system: use a ringtone for a less intrusive arrival notice, or choose the alarm when a louder warning is more useful. It makes sense if you want an audible alert without setting up a more involved monitoring system. The trade-off is that this is a motion alert, not a way to see what triggered it.

Getting the most from it

No specific phone, smart-home, or other device compatibility is listed. The system is described as a transmitter-and-receiver setup, with receivers able to work with as many as 20 motion sensors. You can choose the number of transmitters and receivers for your needs, but the information does not specify how many are included in a package. Check the package contents before planning coverage for multiple entrances or rooms.

For a practical setup, place the sensor where someone crossing an entryway will pass through its detection area, then plug the receiver into a spot where you can hear it. A sensor at a stockroom entrance, for example, could alert someone working nearby when movement is detected. Keep the sensor’s shorter detection distance in mind when deciding where to mount it, the 500-foot figure applies to communication with the receiver, not how far away motion can be detected.

Usage tips

The sensor mounts and runs on two AAA batteries, while the receiver needs a standard outlet. Choose a ringtone and volume that suit the room, then test the alert by moving a hand in front of the sensor. To change the ringtone, use the receiver’s volume or down button to select a sound, hold the volume button for five seconds, or briefly press both buttons, until the receiver chimes and its LED flashes. Wave a hand in front of the sensor to set the new ringtone.

Avoid placing the sensor based only on the receiver’s range. The stated detection area is relatively local, and the product information does not specify weather resistance or outdoor use, so it is safest to plan for an indoor location unless the seller confirms otherwise. You may want to skip it if you need video, remote phone notifications, or motion coverage beyond the stated sensor range.

Questions before you buy

Does the receiver need batteries?

No battery requirement is listed for it, the receiver plugs into a standard outlet. The sensor uses two AAA batteries, which are included.

Can one receiver work with more than one sensor?

Yes. Each receiver can work with up to 20 motion sensors, according to the product details.

Can I choose a quieter alert?

The receiver has five volume levels and 58 ringtone options, so you can select a sound and setting for the space.

Is it worth it?

This system is worth considering when the main goal is a straightforward audible notice at an entry, office, or work area, and the outlet-powered receiver fits your setup. The adjustable chimes and volume give it more flexibility than a basic single-tone alert, while the option to pair multiple sensors may suit people monitoring several spots. Its limits are just as important: motion detection is listed at about 13 to 16.5 feet, and there is no stated video or phone-alert feature. Choose it for a local sound-based warning, look for a different approach if you need to identify visitors or monitor a wider area remotely.
