The present invention relates to an underwater photographic lighting device which comprises: a flashlight body fully sealed by a seal, the interior of the flashlight body is provided with waterproof through holes, the flashlight body is respectively connected to a lamp head and a flashlight via conductive connecting cables, the lamp head is sealed by a seal, and connecting parts can be respectively dismounted from the flashlight body; and a power supply component sealed by a seal and connected to the flashlight body. Every part of the underwater photographic lighting device of the present invention is sealed, so the waterproof function is better; and each part is independent, and therefore can be optionally replaced and maintained. The battery module can be replaced and upgraded according to future need, and can be independently charged, so that the life cycle of the whole device is extended. When a beam head is used for photographing, a reflection cup and a condensing lens that are added on the beam head can increase light efficiency, so that a better photographing and recording effect can be achieved. In addition, since the device can be connected to a camera or a camcorder without a grip, a clamp or other parts, the device is convenient, light in weight and practical.

A wastewater monitoring system uses a camera in a fixed location in a wastewater pipe. The camera is coupled to a sensor that measures some characteristic of material in the wastewater pipe. The sensor is programmed with one or more alarms that, when triggered, cause the sensor to wake up the camera and command the camera to take one or more photos. Sensor data, such as current time/date, location, and the characteristics of material in the wastewater pipe, is sent by the sensor to the camera, which overlays one or more photos with visible text information corresponding to the received sensor data. The sensor can wake up the camera and command the camera to turn on the camera's Wi-Fi interface, which allows a wastewater control system in a remote location to communicate directly with the camera.
