The SMART survey is an ambitious effort to conduct sensitive searches for pulsars and fast transients at 140-170 MHz. The novelty of voltage recording, long dwell times and the high-time and -frequency resolutions exchange a large survey speed for high computational cost. The survey covers the entire sky south of +30 degree in declination through a series of dedicated campaigns, accumulating 4 PB of data. The large volumes of data necessitate processing to be approached in multiple phases, and the initial searches focused on a shallow survey of parts of the skies, as reported in earlier papers. These data are also processed for re-detections of hundreds of known pulsars in the southern sky, many of which are also the first detections below 400 MHz. This paper is motivated by the need to address the inherent difficulties in handling large amounts of voltage data and software/processing challenges for routine pulsar detections, and also by the fast-evolving landscape of the SKA Observatory (SKAO). With the construction ramping up towards the full-scale SKA-Low, a low-frequency catalogue of detectable pulsars in the southern sky will prove to be a valuable reference for science verification. A growing sample of low-frequency detections and measurements will also prove invaluable in a variety of science applications including population studies, survey simulations and emission beam models, refining interstellar medium models for electron densities and the spatial distribution of turbulence, and also for forecasting the detection prospects and survey yield from pulsar surveys planned with SKA-Low. We present various data products, including pulse profiles, time series and multi-channel folded archives, along with the measurements of dispersion and rotation measures, and mean flux densities, and this will be periodically updated as more detections flow on from the ongoing data processing.
