@joseph_1979 Thanks for your replay, Joseph. You have said that the connection diagram above is correct, however you tell me to check out the article that have the same diagram connection plus the alarm device in. So I trying to activate the output relay without the alarm device in, just with the motion detection camara feature. Is it possible?

I have connected a siren to output 1+ 1- as indicated in the following diagram.
But when my Reolink ‎RLC-520A camera detects the intrusion alarm in our RLN36, the siren that we have connected to output 1+ 1- does not activate. As I must configure the software, so that when the camera detects the alarm (intrusion, movement, etc...), the siren that I have connected is activated.
