From SYAC, the latest development for DigiEye is two-way audio. Seamlessly integrated in the user-friendly DigiEye software interface, the audio option allows the recording of one audio channel simultaneous to 15 video channels or the transmitting of audio (full duplex) and video over IP networks. When ordered with the system, the audio option is built into the DigiEye case for maximum ease of installation. Also, the audio option is available in an external version and can retrofit.
