To increase the utility of the portable Beta models companion tuner/timers are available that will turn them into a full fledged home recorders. These allow off-the-air broadcasts or other sources (even a camera) to be recorded. When you done simply unplug VCR and take it with you. The tuner/timer stays at home connected to the TV. This makes the portable even more versatile. These units are styled to match their companion VCR and are made to disconnect easily with little fuss. In most cases an IR remote control operates the VCR when it is connected to the TT unit. When the portable is on it own there is an abbreviated remote available or pause is operated by the camera.
