Product works well enough though can be triggered by leaves blown around in high winds and large wild critters crossing your driveway in the middle of the night. Had one slight adjustment to avoid picking up passerbys on frontage road.

This sound is unlike the sound from the normal sound of a vehicle tripping the alarm. The volume is easy to adjust. I wish the receiver had a rechargeable battery built in like the motion sensor &amp.

The solar panel is slightly shaded. Has port for usb charging.

Solar powered alarm won't recharge. It's solar rechargeable but you can't point it to sun to charge according to the directions.

It beeps at only invisible things. It pairs randomly due to the mhz on the sensors and base. Fedex vans, ups trucks, my own vehicles fail to trigger the sensor.

The distance from sensor to receiver is about 250ft. A very slight breeze barely moving a shrub that is 80 feet away sets it off.

It goes off sooooo many times. It is useless when everything sets it off. Started going off repeatedly in succession during the day as well.
