Guardline Review Update, Troubleshooting Problems With The Alarm, Driveway Alarm Not Working

After four months of use, the Guardline driveway alarm we have been testing has stopped detecting reliably; it will only sound the alarm about a third of the time.

I check the battery's, Turn up the sensitivity, and even fend off some attackers before fixing the problem. Who is the culprit? It appears to have been the backup battery's in the base unit - strange. Turns out the sensor was working great the entire time. This problem defiantly puts a tarnish on the Guardline alarms reputation.
