Security
IP intercom, perimeter audio deterrents, VMS-triggered announcements, and access control audio integration for security-critical environments.
Security applications need immediate, reliable audio response to events — whether automated deterrent messages triggered by CCTV analytics, intercom at access points, or emergency broadcast from a security control center.
Deployment Scenarios
Real-world challenges solved with Barix and BNA products in Security.
Perimeter Intrusion Deterrent Broadcast
Challenge
A secure facility CCTV detects unauthorized access to a restricted area at night. The security team needs an automatic deterrent announcement the moment intrusion is detected — before a guard can respond.
Solution
Barionet 1000 monitors the VMS API and triggers the BNA IP-B501 when intrusion is detected. IP-B501 plays the pre-recorded deterrent message through IP-PA-AZU-300W zone amplifiers to speakers in the affected zone. The Annuncicom PS16 at the security desk receives simultaneous alert for operator follow-up.
Access Control Intercom at Gate
Challenge
A facility needs IP intercom at the main gate for visitors to call the security office, with relay output to unlock the gate upon authorization — all over the existing IP network.
Solution
Annuncicom 200 at the gate (PoE, 8W, relay output) handles visitor calls and gate release. Annuncicom PS1 at the security office receives all gate calls with gooseneck mic. Barionet 50 provides additional relay I/O for barrier and CCTV camera control.
Security Command Center Multi-Zone Control
Challenge
A government security center needs a master intercom and paging station that can reach any of 40 zones across a large complex, with supervised contact closure monitoring of all security relay points.
Solution
Annuncicom PS16 with expandable key field gives the security operator one key per zone. Annuncicom 1000 provides supervised contact closure monitoring of all 40 security relay points — detecting wiring faults in real time. Any fault alerts the operator before a security-critical failure occurs.
License Plate Recognition Audio Response
Challenge
A corporate campus ANPR system identifies vehicles at the main gate. VIP vehicles should hear a welcome message; unauthorized vehicles should hear an access denial.
Solution
Barionet 1000 (Linux/OpenWRT) runs the integration script that reads ANPR triggers and instructs BNA IP9000 controller to play the appropriate pre-recorded message through IP-PA-AZU-300W speakers at the gate zone.
