What’s the difference between the DSC EV DW4975 and the DSC WS4945?


The first and more obvious difference is the visual and aesthetic differences. The EV DW4975 has a slimmer profile and is generally more visually appealing to people. The other major difference is that the WS4945, in addition to the built-in reed switch, has an auxiliary hardwired input. This allows you to take a hardwired device and transmit its openings and closings wirelessly.
