Product details
Product Introduction

Product Introduction



By adopting digital and amplification fidelity technology, clear communication can be achieved in an environment of 120 decibels, and the functions of ordinary network phones can be achieved

Equipped with group setting function, with call methods such as point call, group call, and full call (depending on the functionality of the network server)

The system is based on VoIP, supports SIP 2.0 protocol, digital integrated circuit, stable, reliable, low power consumption, and can also be connected to Ethernet, cross network segment, and cross routing



Application Scenario:


The HWB series IP (network) explosion-proof telephone amplification communication system is suitable for amplifying call communication in hazardous areas containing flammable and explosive gases and strong noise environments such as petroleum, chemical, oil and gas, drilling platforms, oil depots (ships), ports, docks, military, pharmaceutical, mining, etc.
