A remotely monitored boat alarm or marine security system is essential for unattended yachts, cruisers and commercial boats to reduce unexpected maintenance costs, risks to the environment and other vessels, and losses due to theft. 


Remotely monitored boat alarms automatically send alerts to you when problems on board are detected. So you can fix them before they become serious and expensive. Advanced boat alarms offer remote cameras so you can see whats happening on your boat. This can be a tremendous aid when deciding on a course of action to remedy a problem.
