Maintaining a garage security system involves several key steps to ensure its optimal performance. Regularly test the system's sensors, cameras, and alarms to confirm they are working correctly. Replace batteries in wireless components as needed, typically every six months. Clean cameras and sensors to remove dust and debris that could obstruct their function. Update the system's software or firmware to the latest version to maintain security and functionality. Additionally, periodically check for and secure any loose wires or connections. Schedule professional inspections annually to identify and address any potential issues.
