A sensor assembly adapted for remotely monitoring spaces such as residences or businesses, with enhanced privacy. In one exemplary embodiment, the sensor assembly is configured to look like a convention passive infrared device (PIR), and includes a CMOS camera and associated data processing. The data processing selectively alters the image data obtained by the camera so as to allow a remote operator to view only certain features of the data, thereby maintaining privacy while still allowing for visual monitoring (such as during alarm conditions to verify "false alarm" status). Alternate system configurations with local and/or remote data processing and hardwired or wireless interfaces are also disclosed.
