The Datavideo VP-633 3G/HD/SD-SDI Repeater with DC Power Input extends an SDI video signal along with embedded audio 328 ft, reclocking to maintain the quality of the signal. The unit supports resolutions up to 1080i60 NTSC, or 1080i50 PAL, automatically detecting whether the input is NTSC or PAL.

If you want to extend the signal even further, instead of adding another VP-633 at the end of the first 328 ft, you can connect a slightly less expensive VP-634. The VP-634 does not have a power input like the VP-633 model. The VP-633 is the device closest to your switcher, with up to three VP-634 devices extending the chain. The VP-634 features reclocking, and supports embedded audio.
