What to know before buying

The claimed half-mile wireless transmission range is conditional on terrain and ideal conditions. The listing gives no guarantee of that distance at a particular site.
Customer feedback is mixed on operation over time, detection, transmission range, false alarms and alarm audibility. Consider these reports when deciding whether the system suits your coverage and alert needs.

Listing details to confirm

The listing describes sensor operation from -30 to 150 degrees Fahrenheit in its feature text, but a separate technical field states only 150 Degrees Fahrenheit. Confirm the applicable temperature range for your installation. It also describes the 35- and 50-foot figures as both a motion-detection range and selectable sensitivity settings, so treat them as listed modes rather than a guaranteed detection distance.

Who is it for?

A good fit for

People seeking a wireless motion alert for a driveway, gate, shed, garage or similar area.
Buyers who want two sensors and the option to expand the system with additional sensors.

Less suited to

People who need a verified half-mile range at their specific site or a dependable, documented detection result.
Buyers who need a mains-powered sensor or a package that includes sensor batteries.

Customer feedback praises ease of setup and installation, while reports on functionality, detection, range and false alarms are mixed. Some customers say the system works well, while others report it stopped working after a short period. Alarm audibility is also a concern for some, despite appreciation for having different tones. For a buyer relying on the claimed long wireless range or audible alerts in a larger property, these mixed reports make site-specific performance and volume important considerations.

Negative themes

Some customers report that the system stopped working after a couple of weeks.
Some customers say the alarm sound is too quiet.

Mixed feedback

Customer feedback is mixed on functionality, detection performance, transmission range and false alarms.

Frequently asked questions

What is included in this configuration?

The listing's feature text says it includes one plug-in receiver and two motion sensors. The sensor batteries are explicitly not included.

How far can the sensors detect motion?

The listing gives two settings, 35 feet on low and 50 feet on high. These are manufacturer claims, not verified detection distances for every placement.

Does the half-mile range mean the sensors detect motion that far away?

No. The half-mile figure refers to wireless transmission between sensor and receiver, and the listing says actual range varies with local terrain. Motion detection is separately listed at 35 or 50 feet.

Can more sensors be added?

The listing says the receiver can support up to 32 sensors. Check compatibility with the specific sensor model before expanding.
