Seagrid är ett båtlarm som varnar redan vid försök till stöld i motsats till störsändare som endast hjälper till att återfinna stulet gods. En sensorn monteras på de befintliga bultar som håller fast båtmotorn i akterspegeln. Den fästs enkelt på bulten med en medföljande mutter. En basstation installeras på klubben och står i ständig kontakt med sensorerna. Med hjälp av appen kan du enkelt larma på och av samt se händelser och annan information om systemet i realtid. Funktioner: •⁠ ⁠Hantera och agera på larm i appen •⁠ ⁠Aktivera och deaktivera larm i appen •⁠ ⁠Få larm via sms, e-post och pushnotiser i telefonen •⁠ ⁠Alla händelser loggas centralt •⁠ ⁠Möjlighet till koppling mot larmcentral •⁠ ⁠Dokumentera viktiga uppgifter om dina ägodelar om det värsta inträffar och du behöver kontakta polis och försäkringsbolag
