Product Overview

The Hikvision AX PRO DS-PS403I-WB Wireless Indoor Intercom Sounder Plus is an advanced indoor alarm sounder designed for compatible Hikvision AX PRO wireless intrusion alarm systems. It combines a 105dB adjustable alarm sounder with full duplex intercom capability, LED indications and wireless system integration, helping users receive loud indoor alarm alerts while also supporting two-way audio communication where configured. This makes it suitable for homes, apartments, offices, retail stores, clinics, garages and small commercial sites where internal alarm notification and intercom-style response are both useful.
