I am having problems sourcing a speaker & microphone to attach to my NVR for sound monitoring and 2-way communication. My NVR (Hikvision DS-2CD2387G2P-LSU/SL) has 2 RCA ports on the back: Audio In and Audio Out, but I am unable to find any recommendation or source for a simple speaker and microphone I can connect to these to monitor sounds and have 2-way communication through IP Cameras, particularly Hikvision DS-2CD2387G2P-LSU/SL, which I have installed at our entrance and by an outdoor laundry area.
2-way communication and listening works fine using Hik-Connect on a mobile phone, but I want to be able to do the same at the NVR.
