Continuous monitoring of environmental data in remote areas has always presented a unique set of challenges. Typical solutions involve complex installations, frequent visits to remote locations to keep the system fully operational and require expert level attention to retrieve and share data amongst customers, consultants and project leads.

Additional economic challenges can also present themselves on projects that are shorter in duration (e.g.construction sites, wind farm commissioning, concert venues, etc.). In these instances, customers often incur the expense of a permanent installation when a simple, easily deployed, "temporary" solution is all that is required.

The Larson Davis NoiseTutor is an integrated solution, ideally suited to address the challenges of remote noise monitoring in an efficient and cost effective package. Designed for rapid deployment in a network environment, NoiseTutor provides Internet based remote control, a high speed network connection for the rapid transfer of large files, event alerts and real-time reports published directly to the end user’s website.

NoiseTutor allows for easy management of any configuration from a single system to a network of systems, each of which can be individually controlled. A sophisticated power optimization scheme provides individual system power management during low power battery operation, to avoid the loss of critical data in the event of AC power interruption.
