I would like to set up an engine room camera (or two!) in my trawler for monitoring both while under way and, if I can figure out how, monitor while I am at home. *I am curious what inexpensive set up others are using? *When I am @ the boat I could just use a wireless webcam to run it to my laptop (which also works as my chartplotter) but that doesn't do much when I am not on the boat. *I've heard many say they bought their set up at costco or best buy. *Specific models and info on how you set it up/monitor it would be great!
