Model Info

The RII allows a variety of intercom speaker stations to communicate with DVTel’s line of audio enabled encoders and decoders with the Latitude NVMS audio option. All audio enabled 7500, 7600, 8500 and 8600 series of encoders and the 7500 series of decoders including the 9440, 9540 and 9840 series of IP cameras.

 The NetTalk RII with its unique Automatic Level Control (ALC) circuitry, balances inbound and outbound audio levels for a full compatibility with the DVTel audio encoders, decoders, IP Cameras and the Latitude NVMS software.  When receiving the audio signal, it converts to 0dB level from the station. When transmitting the audio signal, it converts the low microphone level (-40dB typical) from the speaker/mic to a 0dB level at 600 ohms for transmission of the network. 

The audio support of the Latitude NVMS provides the ability to monitor, record and communicate with audio call boxes attached to video encoders or decoders.  The Latitude NVMS combined with the NetTalk Remote Intercom Interface (RII) becomes an Intercom Master Station.  A variety of commercially available call stations can be interfaces with NetTalk for maximum system flexibility.  Latitude provides full control of the audio system including push to talk and listen functions and can provide a full system response to a remote call button action.  In addition to the Latitude’s full audio controls, push-to-talk and listen can be accessed from the Latitude CCTV Keyboard.
