Nest Cam IQ - Using low voltage wiring instead of included wall plug
Hi There! Im new to the forums but looking for help with my security cameras. I have old security cameras on my house hard wired via low volatage (network cabling it looks like) to a central multi-channel power supply in my bedroom closet. I want to replace the cameras with Nest Cam IQ Outdoor cameras, so I purchased one to see what I could do. My hope was I could splice the included USB-C cable to my existing low voltage wires, supply the correct voltage at the multi-channel power supply box and be on my way.
No such luck. I'm afraid that Nest has done something special with it's wall adapter, requiring the third, yellow wire, to be attached - possibly to tell the wall adapter how much voltage is needed?
To test this theory, I took both parts of my my newly cut USB-C cable, and connected only the red and black wires to each other. The camera had a red light ring, indicating "Your camera is plugged in but there’s not enough power for it to work correctly. The small status light will be off. Make sure that you plug the camera into a standard household socket." When I connected the yellow wire back up, the camera functioned properly.
Here's a picture of the wall adapter, note that it's output is 5V-2A OR 9V - 3A OR 15V -1.87A.
I'd rather not have to run the included cables/wall adapter through my walls, any help/ideas would be appreciated.
Esta é uma boa pergunta?
