Intercom PCB

The NS-K31T Intercom PCB is a lightweight SIP audio core module developed for IP communication devices such as door phones and entry intercom systems. As a reliable pcb intercom solution, it is built on standard SIP architecture, allowing smooth interoperability with VoIP platforms and enabling stable, real-time voice communication. It is commonly used in sip intercom and compact access control devices where space-saving design and consistent audio performance are required. With PoE power support, installation becomes simpler and more efficient, reducing the need for additional power wiring in poe intercom deployments.

The NS-K31T Intercom PCB integrates essential audio and control functions into a compact form factor. It supports GPIO alarm inputs, LED indicators, and HTTP-based commands for external system triggering and automation. Functions such as scheduled announcements and pre-recorded message playback help enhance operational flexibility in security and public communication scenarios. Equipped with MIC and speaker interfaces, this Intercom PCB is ready for direct integration into end devices. Its stable performance across wide temperature conditions and easy browser-based configuration make it suitable for scalable SIP communication product development.
