Dahua Alarm out connection question

[Myllerman]

I am about to connect a strobe to Dahua camera. I wanted to double check so i dont fry anything becouse when google:ing i saw some different alternetives that made me abit confused
Do i connect the Dahua alarm out -> strobe ground -> strobe posetive (120ma) -> 12v ?
Is this correct ?

Hmm yeah i did not think of that hehe. Feels kind of obvius now that you meantioned it
You mean mesure what happens when i flip the relay if i get a 12v potential between alarm out and 12v source.
Was so long ago i did anything electrical i forgot so much. Thanks.

red one to a 12v source, black one to the alarm output... trigger the alarm, should read 12v, turn the alarm off.. should read 0v

Late reply from me. Yep, works as you said.

Just in case, be aware:
A Strobe placed in the FOV, or that illuminates the FOV, willwreak havoc on the camera's MD feature, esp at night.
Another reason that MD is only useful in special situations.

Hehe yeah i can imagine that could happen. I use PIR on this camera so its ok.
