Id like to have some bit of noise whenever something triggers my cameras 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 Ive never heard, I guess they dont 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 dont 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.

Ive 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.

Pretty much anything where connecting 2 wires together causes it to make sound.

I couldnt find my exact model on a more recent pdf manual I had but the pdf you linked had it.

Kind of, the video goes a bit too fast but for my set up based on my pic of my back panel, if I get everything from the video 12v adapter power jack connector alarm I dont really need that lego adapter thingy So I would have a alarm wire going into one of the ports(green arrow) while the ac wire going into the ground(blue arrow) View attachment 68827.
