CAMS (Circadian Activity Monitoring System) is a simple and efficient data recording system for monitoring activity in large numbers of animals. Developed by chronobiologists, the system is made to meet the needs of scientists for behavioral studies and control of experiments. CAMS has been used to record activity in rodents (mouse, rat, hamster, gerbil), birds, and primates.

Made from solid state, low power components the system is highly reliable, robust and simple to install and use.
