Remote infrared acoustically triggered video monitoring unit Free

A remotely operable, infrared system for recording digital video and audio information immediately before, during, and after an acoustical event was developed. The primary application of this system to date has been the recording and documentation of effects of noise on wildlife, including Peregrine falcons (Falco peregrinus), Mexican spotted owls (Strix occidentalis lucida), and brown pelicans (Pelecanus occidentalis). The system triggers, records, and stores digital video and audio data on an IBM compatible computer running win9x. Serial communication with a Larson Davis sound‐level meter allows a field video camera to store video and audible sound data on the computer. The need for field crew collection of bioacoustical effects data at sites with video acquisition systems is minimized. The video information reduces observation or interpretation bias in the data collection procedures. The systems can be maintained from remote locations using cellular modem technology and can be operated without being visited for extended periods. It is low powered and can be operated by a system of batteries and solar panels for indefinite field deployment. With the correct lens the system is capable of seeing in complete darkness up to 25 ft or as far away as 200 ft in the daytime.
