This system monitors and alarms the next events
     • Entrance door.
     • Water level 1, inside the boat (lower level).
     • Water level 2 (higher level. 35mm above first).
     • Minimal and maximal voltage separately for battery1 (house) and for battery2 (start).
     • GPS location and Geo-Fence area control from 10 to 225 meters.
     • Minimal and maximal temperature and humidity levels inside the boat.
     • Shore power connection. Alarm activated in 15 minutes after disconnect.
     • Emergency alarm button. Activates alarm message with GPS location to all phones.
The owner can setup and change sensor parameters and all actions for any event that is described above by special mobile phone application. The application for Android Smartphone is available for download.
Every event can be controlled and associated with proper actions.

The following actions are available
     • Call (short call, miss call, no voice message)
     • SMS message with alarm, report or confirmation text
     • Starts up to two external loads (bilge pump, siren or another device)
     • Stops external load. (Powered from house battery)
     • Powering ON/OFF extra Outlet with timer by SMS request.
     • Local sound alarm (buzzer) for critical event.     

GPS options can be checked or activated by requests in a proper SMS messages. “Boat Keeper" security system has a separate time settings for reporting and repeat alarm notifications. The time settings can be set with intervals from 1 second to 45 days.
To reduce power consumption, user can select five power modes of functionality. The device has a default factory setting and is ready to use after powering. All of these settings are changeable. Only the reset option can change the owner's phone number and returns device to the default factory settings. (Reset connector is on the board)
“Boat Keeper" security system accepts the change settings from owner's number only. Other extra two phone numbers can be used for communication and manage the device except change the settings. All other calls and messages from unknown numbers will be ignored and deleted. The new device or after factory reset the “Boat Keeper" waits for first call to remember this number as the Owner’s phone number. Only a full size SIM card require for internal mobile module. The SIM card can be on a prepay plan or as a part of owner’s mobile phone plan.



Installation of "Boat Keeper" security and control system

Wiring diagram for 3G mobile boat security and control systemBefore the installation you need to find an optimal location for the main box, door sensor and water sensor. The main box has a built in antennas and should be located in any area with good reception, not covered by metal screens or walls and held above the outside water level.
Non-metal constructions are not a real obstacle for airwaves and do not reduce reception for GPS and GSM networks. The suitable location could be found by using an ordinary mobile phone and viewing the level of reception on the mobile phone screen and GPS functionality. External GSM and GPS antennas can be connected to SMA socket on the main board, instead of internal antennas. The main box can be mounted by four screws on a wall or by any other safety methods (glue, cable tie) in a reachable place for visual control and manageability. The water level sensor can be fixed in an expected water level area. The area should be protected from mechanical damage. Usually, these sensors mounted under the boat’s floor in the lowest section. The magnetic door sensor consists of two parts. First part is the wired switch which can be fixed on a wing of a door or on any other places that is located near a sliding or an opening door. The second part of the door sensor has a magnet inside and does not require any connection. This part should be mounted on a sliding or an opening door. For stable control of a shut door, the distance between two parts of the door sensor should be close as possible and not more than 14 mm.
More attention is needed to provide for cabling between the sensors and main control box. All wires need to be protected from mechanical damages and salt water.
* We recommend an installation service provided by a certified boat electrician.
