Meet Your Local Bay Alarm Representatives
Tim Carney
Ontario Branch Manager
“I have lived in Inland Empire all of my life and for the past 12 years I've had the privilege of working for Bay Alarm helping to provide the best security systems and services in the industry. As part of my ongoing commitment to the Inland Empire and its security, I'm also a volunteer with the Upland Community Emergency Response Team as an Amateur Radio Operator with the title of Specialist Responder. This opportunity has given me a chance to give back to the community in times of emergencies or natural disasters. It has also given me the opportunity to meet many wonderful volunteers giving back to the community as well.”
