After conducting my own research into the effectiveness of the performance and reliability of these apps, I concluded that Guard911’s alert system is superior to anything else out there. This is the ONLY system that has an established network of police, to instantly alert on and off-duty officers of an armed intruder emergency. Guard911 is the only early panic alert company I put my name behind.
