A security system (10) includes an alternating electric current powered motion sensor assembly (30), and a direct electric powered security module (31) incorporating a storage device (63). A digital camera includes a digital camera mechanism (50) associated with the security module (31), and a digital camera lens (51) associated with the motion sensor assembly (30). Wiring (20) coupled between the motion sensor assembly (30) and the security module (31) provides alternating current to the motion sensor assembly (30) and the security module (31). A transformer (61) converts the alternating current from the wiring (20) to direct current electric and supplies the direct current to the security module (31). The digital camera mechanism (50) is responsive to activation of the motion sensor assembly (30) detecting motion in a vicinity (12) of the motion sensor assembly (30) activating the camera lens (51) to make digital imagery of an area in the vicinity (12), receiving the digital imagery made by the camera lens (51) over the wiring (20), and storing the digital imagery in the storage device (63).
