This is an unknown IP camera. Most likely a Wanscam clone, PCB has www.wanscam.com silkscreened but board design doesn't match any known boards in the google database.
Board ID#: AJ118-7A
CPU: Nuvoton W90N745CDG
RAM: Winbond W9812G6JH-6
Flash: Spansion S29GL032N90TF104
So this camera worked fine until I installed it on the house. Its non-POE, so I ran two cables (ethernet and power) power was terminated on each end with barrel Jack's, positive to center electrode. 200% sure it was wired correctly. Unit was powered with the same 12v 1.5A brick that it was supplied with, and what I used for bench testing/initial setup.
The only LEDs on this unit are a red and amber on the ethernet jack on the end of the cable.
Once installed, unit would show the Green LED, but no amber. My POE switch showed 100M HALF DUPLEX. Ethernet cable tested good, I was also able to plug my laptop into the same run and establish a connection.
I then powered the unit locally with a mains extension cord. This time the green and amber LEDs lit, but did not request an IP from the router. A packet dump of the interface shows ZERO packets being sent from the Camera.
Removed camera from its installation, tried again on the bench. Both LEDs light, again no ethernet packets sent.
This unit has an unpopulated serial header. Verified the TX and RX pins on the header are connected to the UART0 pins on the SoC. Connected my TTL<->USB converter to the serial header on the board. Powered unit on. No serial output AT ALL (Tried at 115200 and 9600).
At this point I'm out of ideas.
