A surveillance system for residential buildings that monitors the status of occupants for their location, position, and movement. The system employs a sensor that is mounted near the ceiling or on the floor in each room of the residence. Each sensor continuously scans the X, Y and Z axes for the location and position of objects each room. The sensors are coupled to a digital image processor that uses software to evaluate the stream of location and position data to determine whether occupants are moving, and whether their activity indicates an or normal or emergency condition. The surveillance system can be adapted for any building or room configuration because upon setup it generates and stores a database of map information about the building it is installed within and that map data is thereafter used to evaluate the stream of location and position data. When abnormal location, position or movement of a monitored object, typically a senior citizen, is detected by the system an alarm state is automatically triggered and an emergency notification signal is transmitted to emergency response personnel.

A device (10) for detecting the presence of light averse insects, such as termites, is in the form of a peg (11) having a cavity (14) into which termites may enter when the peg is installed in the ground or other area where the presence of termites is to be detected. The cavity may include a termite bait. A light sensor (25) is located in the cavity, and has an output which is responsive to the detection of light. The light sensor operatively receives light from a light emitting device (LED) (23) only through a narrow passage extending through the peg from the LED (23) to the cavity (14). The passage is adapted to be at least partially blocked by the light averse insects to shield the cavity, and hence the light sensor means, from light from the passage. When the light sensor means (25) does not detect sufficient light, an electrical circuit (22) connected to the output of the light sensor means triggers an alarm light (26) to signal an alarm or alert condition.
