The M-Series Door Station Camera models(a 14mm pinhole camera installed) include DP38-NBMV, DP38-NBKMV, DP38-NBZMV, and DP38-NSMV. These units provide standard door-to-phone communication when used with the DP28-C*. A new design not only brings great new looks, but great new additions as well. An optional weather-proof back box provides quality protection and durability for your unit. All MSeries Door Stations mount into any standard Music and Sound’s box as a flush mount. Optional back boxes (DP38-BXMF and DP38-BXMS) are available as both flush and surface mounts. Colors are available in 4 anodized finishes: brass, black, bronze, and aluminum. These Door Stations are also available in kits with the DP28-C as the DP38-BM, DP38-BKM, DP38-BZM, and DP38-SM.
