Method of monitoring water conservation in an apartment complex by
positioning infrared cameras with motion sensors in the clean outs of the
waste water discharge lines leading to public sewer systems wherein each
camera image is displayed on a computer screen and the motion sensors,
which start and stop the digital video recorders (DVR), are adjusted by
circumscribing the area of the camera image and the pixel sensitivity
setting for motion sensors activation, which triggers the DVR recordings.
In this arrangement the intermittent or constant flow of waste water is
detected in real time indicating normal or abnormal flow of waste water,
respectively. Further, an infrared camera may be positioned on the
apartment complex side of the water meter to determine in real time if
water is being supplied to the complex and the waste water flow out is
little or none then loss of water outside the plumbing system from
overflowing commodes, tubs, lavatories or broken pipe is indicated.
