GOST NT-Evolution Hard-Wired Marine Security and Tracking Package

The NT-Evolution package is GOST's hard-wired flagship marine security and tracking solution, sized for owners who want the system installed permanently in the boat rather than running over a 4G or Wi-Fi link that can drop out. The IDP 100x satellite backbone keeps the system online globally as long as the boat has a view of the sky, which is what separates a true marine security system from a residential alarm panel adapted to a yacht. If somebody steals your boat or it breaks free on a mooring in a storm, you get a real-time GPS position and an alert on your phone within seconds, anywhere on Earth.

The package is designed as a complete kit. The 110 AC Power Out module (GNT IP68 110AC POWEROUT HW) is the IP68 waterproof shore-power monitor that watches whether dock power is connected and active. Lose shore power and the system knows, which is the early warning for a refrigerator failure or a frozen condenser before the food spoils or the AC trips on the inverter. The GDC EXT WGHD door and hatch contact is the water-resistant magnetic contact for securing companionway hatches, cabin doors, and engine room access points. The GNT IBS 1 beam sensor is the IR emitter-and-receiver pair that protects the perimeter of the boat: if anyone walks through the beam between the emitter and the receiver, the siren triggers. The GMM HWS high water sensor is the bilge float switch that mounts slightly below the factory-installed bilge high-water alarm, giving you a second warning level before the bilge actually fills.

Output devices are sized for a marine install. The GA STROBE WHITE strobe is the visual alarm: ultra-small, surface or internal mount, semi-hemispheric white LED with 25 flash patterns plus a synchronize feature for running multiple strobes in alternating or matched flash. Put one at the helm, one at the stern, and one in the engine room and you've got visual confirmation of an intrusion from anywhere on the boat. The GA-MINI-SIREN is the audible alarm: 125 dB at 20 watts, multi-tone, water-resistant. That's loud enough to be heard from the next slip over and persistent enough to draw attention rather than just annoy a thief into cutting the wires faster.

The user interface is the GMM KF2 keyfob: water-resistant, compact, backlit buttons with auditory feedback for arming and disarming. The fob handles up to six actions per remote with a range of about 150 feet, which is enough to cover the dock-to-boat walk plus the parking lot at a marina. Arming and disarming the boat without pulling out a phone is the workflow most owners want, especially when you're stepping off the boat with hands full of gear. The hard-wired zones (Hatch Z2 Normally Closed, Beam Z3 NC, 110 AC Z4 NC, High Water Z5 Normally Open) map cleanly to the GOST panel logic, and the ComBUS four-wire connection is what links the sensors to the panel through clean low-voltage runs rather than individual home runs to each device.

One thing to know about this system. Installation is meant to be done by a marine electronics installer rather than as a DIY weekend project. The wired runs through the boat, the antenna placement for the IDP 100x satellite link, the strobe and siren mounting locations, and the panel power feed all need to be done right to avoid false alarms and missed alerts. GOST sells the package and supports it, but the install is a contractor job. We can recommend an installer in your area, and we'd suggest scheduling the install when the boat is hauled or at minimum when you have a long weekend to dedicate to it. Note from the manufacturer: this product cannot be returned to the original point of purchase, and warranty service goes through GOST directly. We'll help you coordinate the install scheduling and answer compatibility questions on the front end before you commit to the kit.
