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.

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.

Solution retenue

red and black cables is power supply, yellow should be video cable, and ac adapter is actually your communicator between your camera and wifi point .

so for each camera you have to use separate ac adapter .

So we have the exact same situation with an old hard wired Everfocus DVR system and Hard wired cameras. Is there any solution to reuse the power cables run to the camera locations with new wireless cameras? This old system was designed in 2009 and does not have wireless capabilities.

Michelle please open new topic with more detailed info what you want to do with cameras

par

that is the most stupid thing i have ever heard. Yellow cable is video??? is this an analog composite video camera? Forget everything this guys said. AC adapter is NOT the Wifi commuticator, however you cannot use another power adapter as the camera needs to "see"that specific power supply via the yellow cable. You can power up the camera with any USBC cable, or splice it no problems.

par

If I had to guess i would guess that yellow wire is a voltage sense wire, used to detect the voltage droop along the long cable. If this is correct, this could be used by the power supply to adjust the output so the correct voltage is sensed at the camera. But this is just a guess.

I’ve experienced the same issue when I needed to extend the Nest Outdoor IQ power cable, and run it through electrical piping.

The Nest Outdoor IQ works with a 3 wire core cable plus original Nest Outdoor IQ power supply only.

You need to use a cable with 3 wire cores, 2 for power +/- and 1 for communication with the original adaptor.

Cut the original Nest power cable in half , and solder a 3 wire core cable in between, connect to the original Nest Outdoor IQ power supply, and it will work. Tip: use extension cable with 2.5mm2 thick core wires.

Does anyone know how far I can extend the cable without interference, quality loss, or failure. The longest position is 200 -220 feet

par

300 meters should be the amount you can extend

Can I just crimp the wires together with ends? Why is it necessary to solder?

I would just be twisting and crimping two different "nest usb-c" wires together...

Yes, we just crimpped the wires together using small wire connectors like in this post: https://www.onehoursmarthome.com/blog/ne...

par

You can crimp the wires and use a B-Connector
