Question:
Can GV-Eye use two-way audio to communicate with NVR/VMS/Recording Server side?
Answer:
No, GV-Eye v2.4.2 cannot use two-way audio to communicate with the software host, even you connect microphone and speaker to the PC.
GV-Eye v2.4.2 two-way audio only works in two situations.
1. Communicate with camera that connect to GV-Eye v2.4.2 directly.
2. Communicate with camera that connect to GV-Eye v2.4.2 through Recording Server.
NOTE:
When the cameras are connected to GV-Eye v2.4.2 through DVR/NVR/VMS, it only supports one-way audio, which means user can only hear the voice on camera side through GV-Eye, but cannot talk back.
