About Vessel Monitoring

Boat Monitoring Systems

Boat security and vessel monitoring are the same. Keep her floating and safe in her slip ? that's the goal. Vessel monitoring systems warn owners in times of high water, pressures, temperatures, and more. Underway Defender's selection of boat monitoring systems offers course alerts and engine fluid pressure alerts.

Boat security - what does it mean to you?

If you don't nap when the autopilot is on course alerts may not be in your wheelhouse. To you, high water, high pressure, and smoke or fire alarms could be the highest form of boat security monitoring. Boat security means something a little different to everyone, thankfully display interfaces allow owners to monitor what lets them sleep at night and that is what boat security is all about.

Modern monitoring

Displays with full interface allow boat owners to monitor just about any system they would like. At the same time, today's boat security systems offer audible as well as visual alarms, raising the warning alarms with light and sound. And for a really good night's sleep boat security monitoring systems are also available with remote access, and some can be monitored very simply with any smartphone.

Not your momma's video doorbell

Modern boat security systems and vessel monitoring systems offer so much more than just a visual diary of a boat at the dock. Today pressurized systems, tank levels, and the temperatures of engine and transmission systems join the monitoring of electrical flow, fire, smoke, and fluids. Technology is great when it comes to options for boat security systems!
