1. Introduction – What is Hanwha IP Audio System (IPAS)?

Hanwha’s IP Audio System (IPAS) is a network-based audio platform designed to deliver live and pre-recorded messages over IP speakers and audio modules.

Instead of wiring passive speakers directly to cameras or NVRs, IPAS moves audio to the network layer, enabling centralized management, zoning, automation, and seamless integration with Wisenet cameras, VMS platforms and external systems such as access control, BMS (relay or HTTP triggers), and SIP PBX systems for live paging.

Typical applications include:

  • Security and deterrence (audio warnings on intrusion / loitering).
  • Safety and evacuation messaging.
  • Operational paging in warehouses, factories, retail and transport.
  • BGM (background music) and scheduled announcements.
