Web Cam used as security device (Score 1)

The Creative WebCam has a feature where it will only trigger if it senses change (with variable sensitivity). Then you have the option of either storing a single image (or a videa - time lapse specified by yourself) to the local hard disk. In addition it can publish image changes (one per event) to a web site. Your could setup the upload to the web site (it uses FTP) to be done via cell-phone/modem. You will be able to monitor the website for changes (displays from 1 to 10 images). Alternatively setup the cell phone (on the boat) to call your personal cell phone - it will not succeed with the ftp upload, but at least you will know that there has been a change in view at your remote site....
