N-8540DS IP Door Station
N-8540DS
The N-8540DS is an IP door station employing packet audio technology. Connecting the N-8540DS to an IP network (LAN or WAN) permits hands-free conversation of high sound quality to be made between the N-8540DS and the intercom station connected to the IP Intercom Exchange, or between the N-8540DS and an IP multifunctional master station. Besides, the N-8540DS can be used in conjunction with the Multi Interface units through a network. It is in full conformity with IP54 water-proof and dust-proof standards. The operating temperature range is -10 to 50 ℃. As provided with guard nets inside to cover over the openings of microphone and speaker, the N-8540DS can be installed free from care in public space.
