Abstract: A wastewater monitoring system uses a digital camera in a fixed location in a wastewater pipe. The digital camera is coupled to a binary sensor that provides a binary trip signal that indicates when the sensor detects wastewater in the pipe exceeding a defined threshold. When the digital camera detects a trip signal from the binary sensor, operating logic in the digital camera changes frequency for taking pictures. The digital camera preferably adds visible data to a stored digital photograph file that may include any or all of the following: camera serial number, state of sensor(s), temperature, battery level in the digital camera, and battery level in the sensor(s). The visible data is stored in the digital photograph file such that the visible information is overlaid on the digital photograph so it is visible to the eye of the person viewing the digital photograph.
