We report the technical realization and performance of thirty temporary seismic broadband deployments for the AlpArray project in eastern Austria and western Slovakia. Reftek 151 60s sensors and Reftek 130/130S digitizers form the core instrumentation of our seismic stations; these are mostly installed inside abandoned or occasionally used basements or cellars in small buildings or huts. We describe our type of installation and briefly introduce the site conditions for each of the thirty installations. We present a probabilistic power spectral density analysis to assess the noise conditions at all sites and potential relations to the installation design.
