Marine Guardian®

This Security Device is the solution for: boats, yachts, and similar marine applications. Products are customizable.

Boat/Marine Security System

Contractor Guardian Guarantee Anything can happen at anytime to your boat or other marine application: theft, vandalism, fires, power loss, and more. Unfortunately, you will not always be there to stop the daily threats your boat faces before severe damage or loss occurs. The wireless boat security alarm system, Marine Guardian®, will protect and provide notification against the most prevalent threats to your boat. At the same time, it gives vessel owners the ability to remotely activate and deactivate electronic devices on board. The Marine Guardian® will help secure your marine application, preventing loss or damage by monitoring your marine application wirelessly.

How It Works

Marine Guardian® Marine Guardian® builds a virtual fence around a docked boat, using wireless sensors to detect unauthorized entry, smoke, fire, high water levels, irregular bilge pump cycles, loss of shore power and low battery voltage. If a sensor is triggered, Marine Guardian® will call up to three phone numbers three times with an event specific message. You can then take the proper action. Marine Guardian® takes some of the worry out of boat ownership. See our demo for details.

Secure Online Account, At Your Service

All security systems are integrated with our server. Each Guardian Systems security system owner has a secure online account where a history of events is logged for viewing. By logging on to the web site at anytime, you can view the status and condition of your property.

In charter applications, a user may want to monitor engine speeds or temperatures. Commercial users may want to track fish hold temperatures. If you purchase a different boat, your Marine Guardian® security system can go with you. As your needs change Marine Guardian® can be customized, updated and upgraded to accommodate at any time. The simple removal and installation of the wireless sensors makes the transfer easy.
