How It Works
Works like a smart home system. On your boat.
Vanemar brings together updates from your boat’s wireless sensors and connected systems, from bilge water and smoke to batteries, cabin climate, and engine data. Wireless sensors mean no cable runs, no drilling, and no waiting for an installer.
Vanemar Gateway
The Gateway is the heart of the system. It collects sensor data and sends it to the Vanemar app, so you can monitor your boat remotely. It also tracks location and measures the voltage of the battery it is connected to.
Vanemar Kamera
Check in on your boat anytime. When it detects movement while you’re away, it records the activity and sends a notification to your phone.
Smoke Detector
Alerts you when it detects smoke.
Bilge Water Sensor
Alerts you when the water level in the bilge rises.
Carbon Monoxide Detector
Alerts you when it detects carbon monoxide.
Battery Monitor
Monitors the battery and alerts you when its voltage moves outside the range you set.
Motion Sensor
Alerts you when it detects movement on board.
Entry Sensor
Alerts you when a door or hatch is opened.
Smart Plug
Turn your fridge, battery charger, and other plugged-in devices on or off remotely. Check whether shore power is available.
Temperature & Humidity Sensor
Alerts you when temperature or humidity moves outside the range you set.
NMEA 2000 Adapter
Brings compatible engine, fuel and tank data into the Vanemar app.
Bilge level normal. No smoke detected. Battery charged.
See how your boat is doing at a glance. If something needs attention, Vanemar lets you know.
Your boat from every angle
From location and bilge water to batteries, security and NMEA 2000 systems, Vanemar brings your boat’s critical information into one app.
Details
When Vanemar Camera detects movement while you’re away, it records a clip, creates an event and sends a notification to your phone. You can review every recording in the Vanemar app with its date and time.

This is the forth boat
This is the forth boat monitoring I installed and it was the easiest to install and setup. Pairing of wireless sensors was very efficient and error-free. The process offered detailed in-app instructions. Everything is working as expected and in the case of the NMEA 2000 gateway, what I see exceeds expectations.

COMMON QUESTIONS
Frequently Asked Questions
Straight answers to the questions boat owners ask most.
What are the benefits of a boat security system?
Vanemar’s smart sensors detect unusual events such as unauthorised entry, movement or changes in onboard conditions. If something needs your attention, an instant phone notification gives you the chance to respond quickly.
Is Vanemar suitable for every type of boat?
Yes. Vanemar is a flexible, adaptable system for boats of different sizes and types, including sailing boats, motor yachts, fishing boats and commercial vessels. Its monitoring and control features can be configured around the needs of each boat.
Can I customise the alarm system to suit my needs?
Yes. You can choose and configure different sensors, set the conditions that trigger an alert, and decide how and when notifications should reach you. This makes it easy to tailor the system to your boat and the way you use it.
Can I add more sensors or accessories to the system?
Yes. You can add more sensors and accessories from the Vanemar ecosystem whenever you need them. The system is designed to be flexible, so it can grow with your boat and your monitoring needs.
How does the boat alarm system work?
Vanemar uses sensors placed around the boat to detect events such as unauthorised entry, high bilge water, smoke and carbon monoxide. When it detects a risk, it sends an alert straight to your phone so you can act quickly.
Do I need a professional installer?
Usually not. Vanemar Gateway and the wireless sensors are plug and play. Place the sensors, connect the Gateway to the battery and you’re ready to go. Installation takes about 30 minutes. If you’re not comfortable working with a battery connection, we recommend asking a qualified professional for help.
What is the minimum hardware I need to get started?
You can start with Vanemar Gateway on its own. It monitors the battery it is connected to, provides location data and lets you create a geofence. You can then add extra sensors whenever you need them.
Do I need to be near my boat to monitor it?
No. Vanemar connects to supported mobile networks through its built-in Global Data connection. As long as the boat is within coverage and has an active Vanemar Connect subscription, you can monitor it remotely.
