Abstract: Methods and modules for protecting pumps are provided, the modules having a sensor for detecting leaks of the pump seal, a sensor for detecting rain and/or a sensor for detecting that the pump is running dry and thus is overheated. Each sensor communicates with a circuitry configured to shut down the pump until the problem is resolved and to send a notice or alarm to a person or a system. A reset button may be provided to override the shutdown of the pump by the circuitry. Methods of using the modules are also provided.

Abstract: An underwater light and camera system having a video camera with a camera lens, a pool light with a light source and a pool light lens, and an anti-reflective shield surrounding a clear portion of the pool light lens. The pool light lens has the clear portion and a plurality of ribs disposed on an outer surface of the pool light lens, other than on the clear portion of the pool light lens. The anti-reflective shield is darkened to prevent light from the light source and light reflecting off a portion of the pool light lens disposed outside the anti-reflective shield to directly reach the camera lens.
