Ideal for access control and emergencies, the VI Series enables clear two-way voice communication. With a single button press, visitors reach operators, who can grant access remotely. Built-in Acoustic Echo Cancellation, Adaptive Noise Reduction, and Automatic Gain Control algorithms ensure clear, reliable audio under various conditions.

Designed for harsh environments, the VI Series features a vandal-resistant front panel that resists impacts and tampering, ensuring long-term durability and operational security in public and high-risk locations.

The VI Series intercom is equipped with a built-in tamper detection feature that identifies unauthorized removal or forceful disassembly. When tampering is detected, the device instantly triggers an audible alert or notifies the security room to enable timely intervention, enhancing site safety and device integrity.

Users can predefine up to 5 call destinations. When the line is busy, not answered, or the device is offline, calls can be automatically forwarded to the next destination, ensuring calls are not missed during emergencies and always reach someone in time.

Authorized personnel can remotely control door strike using DTMF signaling during a call session. This enables security teams to verify identities and grant access in real time—for example, allowing entry to visitors, staff, or delivery personnel at facility entrances without on-site interaction.
