Update System Software or Firmware
Modern security systems use software to manage alerts and monitoring features. Updates may improve system performance and security.

An annual security system inspection helps confirm the alarm system communicates properly with the monitoring service.
Inspect Wiring and Power Connections
Wired alarm systems rely on cables and power connections. Over time, loose wires or damaged connections can affect performance.
