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.
Es esta una buena pregunta?
That explains why the wall adapter is so big. I plan to have 6 cameras, so 6 wall adapter all in the same metal junction box. I hope they don't interfere/overwhelm my router.

Usually you should make ~12-25cm gaps between plugs, due interference. And make sure your wifi adapter is capable to handle that amount of devices. Dont forget that each phone , pc and etc in household is using same router

Did you end up solving this? I tried using this adapter and it didn't work for me: https://www.amazon.com/gp/product/B01FCW...
I'm not sure if it's because of something proprietary in the Nest power adapter, or if it's just a standard voltage negotiation issue. I've managed to get the camera running with a 3rd party USB C cable (after sanding down the sides of the connector so it would fit), but I haven't been able to get a third party power supply to work yet.

Has any one cut the 25 foot outdoor power cable to the new IQ outdoor ? I am ready to install and I do not need all the cable and it would be cleaner if i could splice it. Anyone have feedback?

I’ve cut the cable to extend it with a piece of cabling soldered in between.
But you can aswell cut the cable, and shorten it, I don’t see any problem there .
Just be very carefull when cutting and stripping the IQ cable. In between the thick black and red wire cores of the flat cable hides a very small yellow communication or video signal cable.
