Hey all, I'm looking to add an alarm to my Dahua brand NVR but I have no experience with alarms or the whole wiring thing. I'd like to have some bit of noise whenever something triggers my camera's IVS rules so I set my NVR to buzzer whenever something is triggered and I was pretty disappointment at how bad it was. It just gives the most pathetic 2 silent little beebs I've never heard, I guess they don't want you to disturb the people breaking into your home.
So I want to add an alarm output, I guess, to my NVR but I don't know where or what to look for in an alarm. Like, I can use just any alarm? My Dahua NVR model is a 4208-8P-4KS2 if that helps. I've read the Dahua wiki and the wiring seems simple enough, a ground wire would go into the ground port and the other wire goes into the numbered ports? Also one last dumb question, what are Input alarms? I saw input and output alarms in the pdf manual and got mixed up a bit.
