D3D builds the wireless home security hardware behind every alarm system, sensor, and siren sold on BigPassport, all designed to work together as one expandable system rather than as disconnected gadgets. The ZX-G12 alarm hub is the center of the range, pairing wirelessly over 433MHz with door and window sensors, motion detectors, and a strobe siren. Every sensor mounts with adhesive or light screws rather than requiring drilling or wiring, making the whole range as suitable for rental apartments as owned homes. This page covers the complete D3D lineup, with our dedicated home security guide walking through how to actually build a system from these pieces.
