Im looking for a boat monitoring system. I want to monitor, high bilge water, battery voltage and some pressure mats / door switches for intruder protection. The boat is slipped at the customers house which is 1200ft away from the lake. There is no shore power available so Im looking for something that is run off of 12 volts and comes with a cell phone dialer or transmitter / receiver. The only thing I have been able to find is from voicealarm.com. Has anybody used this system or does anybody know of any other products on the market? Thanks for your help! Muc
