Crittercam is an animal-borne imaging and environmental data-logging instrument used to study large vertebrates in aquatic habitats. This paper describes an advanced Crittercam system that records video, audio and environmental data to solid-state digital media. This fifth generation
(“GenV”) system is smaller, much more rugged and user-friendly, and incorporates significantly greater data-logging capacity than previous animal-borne video imaging devices. The GenV Crittercam also includes three-dimensional dive path logging capabilities by capturing magnetometry,
accelerometry, water velocity and depth. A graphic user interface enables simplified programming of GenV Crittercam units for diverse data and video gathering needs. These improvements offer opportunities to employ Crittercam in studies of smaller species and in more rugged environments, greatly
expanding utility of this direct observation tool in ethological research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
