TEAC VP-101N is the only voice-logging solution in its class that features Ethernet/LAN Access for expandability/scalability. The system could be expanded easily and quickly if needed with centralized control. It is Disaster Recovery Ready. Centralized control reduces cost of operation and maintenance and increases efficiency of the recordings and monitoring. Up to 24 units can be managed from one PC alone. Competitor units operate through USB connection that is not expandable at all. VP-101N features endless hours of recording by storing data on its internal and server storage both. No other product offers this feature as they store the recorded data on their internal storage alone (SD, HDD) which is limited and risky! VP-101N can store the data on the server which then can be searched and monitored from centralized location.
