Messenger Systems

The NHDS Messenger System was designed specifically as a low cost method of monitoring remote sites or processing plant outside normal working hours.

Made up of any number of Messenger units (monitoring inputs from your production processes, plant or simple status inputs) communicating over air  using mobile phone technology to a central PC which is used to display incoming alarms and status changes as well as for archiving and exporting data.

For smaller schemes where only a small number of Messengers are required, the units can be configured to report alarms directly to mobile phones as text messages. In this case there is no need for the Host PC.

The system can interface with existing Network Management Systems and other corporate PC users over a LAN (Local Area Network) or WAN (Wide Area Network).
