The DTL-4800P digitally records CCTV images onto S-VHS tape at more than 520 TV horizontal resolution lines and as such produces very high quality recordings that cannot be matched by analog VCRs. The DTL-4800P has a recording capability of 37GB (when used with Sanyo SE-ST-180XZES S-VHS tapes) making it possible to record 4 times as many fields on a tape compared to VHS recording.
