Which camera trap type and how many do I need? A review of camera features and study designs

Rovero, Zimmermann, Berzi, and Meek provided a practical review answering the questions newcomers most often ask: what kind of camera to buy and how many to deploy. They compared camera features such as trigger speed, detection zone, flash type, and battery life, and linked these specifications to the requirements of different study goals, from species inventories to density estimation and behavioral studies. The review also discussed how survey objectives dictate the number of stations and deployment duration. By translating technical specifications and design principles into actionable guidance, it became a go-to orientation for planning camera-trap projects. It is widely cited as an accessible primer that helps researchers match equipment and design to their ecological questions.
