Title: High "False Signals"
Review: The unit did nothing but give false alarms every 10 seconds.Troubleshooting with the manual suggest applying tape to narrow the beam.The receiver also may experience false signals due to "wireless routers"...etc.The sending unit may give false signals in direct sunlight.I ended up taking the unit apart (since it was money lost anyway) to see the inside.No way to adjust the sensitivity of the unit was noted.Save your money and avoid this product unless you want to install it for the blinking red L.E.D. for people to see.
