I was given an old Asus tablet and would like to use it to view video from CCD cameras I have (composite output cables), using them mounted on a pvc pole to check out the gutters, roof, etc for any problems. I’ve used the cameras in the past with an old portable TV and RF modulator but that is bulky. Can I use the cams with my tablet if I have the right adapter? I do see that endoscope cameras are being offered these days for Android smart phones and even tablets. Some offer wifi, some just look like they connect to the usb port. I do NOT want any apps, will not download such or use them. What equipment would I need to get the tablet to work with these old cameras or the newer endoscope cams? Anyone know of web sites that can help me set up such a system?
