Camera monitoring

Underwater video cameras provide an effective method for monitoring fish behaviour in conditions of low turbidity and reasonable water clarity. Footage is stored on a hard drive and analysed manually by visual inspection or through image analysis software that records fish passage events. Total fish counts and even species identification can be recorded with high levels of accuracy.       

Typical locations for a camera monitoring system include fish passes and hydro turbine installations.

The size of the installation determines the number of cameras required. A large Larinier fish pass may need 6 cameras, while 2 would be sufficient for an Alaskan A. Infra red lighting panels improve image quality and the efficiency of fish detection.  For remote sites without electricity, there are a number of options for powering the system including Hydrogen fuel cells, solar panels or micro water turbines.  Equipment is housed in weather proof stainless steel boxes.
