As far as the use a traditional CCTV is considered, it is not the right solution for you. As you want to receive the videos through your computer at home 3G surveillance can work. Or the car dash camera can work in this situation. However, as it is required to have a good internet connection to the camera, I suppose a 3g connection to a DVR camera can do the trick. I have heard of something similar named cudaeye. Or you can consider contacting a security expert nearby for consultation or installation.
