I agree with your sentiments.

You need these to use my method:
1) WiFi access where your boat is.
2) Wifi (IP) webcam with external alarm input.
3) 12v to 5v converter (they are cheap) for webcam
4) 12v relay
5) wire going to bilge pump switch
6) wires and crimp connectors to connect everything
7) a circuit breaker switch that you leave on, or an in-line fuse
8) email address to receive alarms
9) electrical tape to eliminate webcam's pan and tilt
10) optional - long range wifi
11) you need to setup the webcam, including setting it up with your email address. This took me significant time to figure out. (It still takes me too long to re-do.) But there are resources to help. It needs to be done with a laptop.

Except the optional long range WiFi, all of the parts are under $100. I just saw some really cheap webcams on eBay that have the external alarm input. You get motion detection for free, by the way, with emails sent to you, showing the inside of your boat when something is detected.


Great minds discuss ideas;
Average minds discuss events;
Small minds discuss people.
The best minds discuss sailing (and a little bit of politics). I don't know why. It's a mystery!
