How preventive and corrective maintenance differ in cost, downtime and risk. A camera that stopped recording last month will not tell you. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Preventive: planned, cheaper per issue, less downtime. - Corrective: unplanned, urgent, often more expensive. - Security systems fail when you need them most. Quick answer Preventive maintenance is scheduled work to stop failures: cleaning, testing, replacing batteries before they die. Corrective maintenance fixes things after they fail. Relying only on corrective maintenance feels cheaper until a failure happens at the worst moment, which for security systems is exactly when they're needed.
