Not able to power on OAK D pro PoE

ShivamSharma

I'm using this PoE injector to power an OAK-D Pro PoE camera. I've installed the DepthAI V3 SDK from this link. The camera is connected via Ethernet through a Netgear Wi-Fi router to a Windows 11 PC. The injector shows a green power indicator, but there are no lights on the camera.

The data cable is connected to the injector's Data port, and the power+data cable is connected correctly to the appropriate PoE port. The camera connection appears secure. DHCP is enabled on Ethernet, so both the PC and the camera should be on the same subnet.

Could someone from DepthAI assist in getting the camera powered on and recognized by the system?

E.g. when I run a code example:

(venv) PS C:\Users\ssharm21\depthai-core\examples\python> python Camera\camera_all.py
Traceback (most recent call last):
  File "C:\Users\ssharm21\depthai-core\examples\python\Camera\camera_all.py", line 7, in <module>
    device = dai.Device()
RuntimeError: No available devices

Does your PC also have a WIFI card? Can you try disabling it for a moment and retrying the connection? Perhaps the WIFI interface has priority over the ETH.

Do you seen any communication/transmission lights on the injector/router signaling that the device is communicating with the network?

Thanks

jakaskerl I tried that by disabling the wifi and camera still did not work. I believe green light on the injector means everything is good. When I had connections wrong on the injector the light was orange. BTW I am not using the wifi from this netgear router, this wifi router is a different one.

Yes that would be a great recipe for the issue I mentioned above. But if you turned off the WIFI and it still doesn't work, the problem must be elsewhere.
Can you map the subnet of your switch to get the ip of the device? nmap -sn ip/mask should work

Thanks,

jakaskerl Okay, I removed the middle man. Now the injector is directly connected to the laptop and the wifi is off. The output of the command is:

PS C:\WINDOWS\system32> nmap -sn 192.168.1.0/24
Starting Nmap 7.97 ( https://nmap.org ) at 2025-06-26 10:16 -0700
Nmap scan report for 192.168.1.11
Host is up.
Nmap done: 256 IP addresses (1 host up) scanned in 45.33 seconds
PS C:\WINDOWS\system32>

I think the green wire that came with the camera is faulty, because I don't see a light on the camera and networking should not prevent the camera from powering on.

If you connect to the device directly - the IP of the device will fall to 169.254.1.222. You will have to manually set the IP of PC's ETH interface to that same range (mask is 16).

jakaskerl Okay, I was able to connect. Also, if I want to use a router in future, how do I connect to this camera assuming I am connected to another Wi-Fi network?

Does the camera not have a light to indicate whether it is powered on?

When connecting, specify the device IP. dai.Device(deviceInfo=dai.DeviceInfo("IP"))
