I’m not very good with electronics but I have a cellular Wi-Fi camera that has a small speaker that you can talk on. I’m trying to figure out how I can use that signal to trigger a 12v relay. When I tested the speaker wire with my meter I had the meter set on 2 ac and it would only register .05 is there any way to make that trigger a 12v relay? The camera is a riolink go cellular camera. I’m trying to use the camera speaker to trigger a relay to drop a gate on a hog trap. Where I could release the gate from the camera app by talking. If I can make this work I wouldn’t have to have a second device that requires another SIM card to control the gate. Any help would be greatly appreciated
