TOA Electronics, Inc. introduces the new VS-900 Security Intercom System. This product has been designed and engineered to integrate seamlessly with access control and video surveillance equipment. With the industry-standard RS-232 interface, the compact and rugged VS-900 allows users the ability to program and monitor software and maintain multiple exchanges offsite from one PC. The VS-900 allows users the ability to create a security system specific to their application with support for single-line telephone equipment with caller ID. It also lets users forward calls manually or automatically throughout the system to outside telephones, cellular telephones and pagers. The VS-900 also comes with scan monitoring, which automatically scrolls through sub-stations for real-time audio monitoring.
