IMOU IPC-S6DP-5M0WEB-E27 Wireless Bulb Cam 5MP (Dahua based)

[RepoLeved]

Hi everyone, I'm opening this thread to talk about this Imou IP camera, model IPC-S6DP-5M0WEB. It's a small light bulb-shaped camera with decent video resolution, night vision isn't bad either. It has a built-in microphone, speaker and car/ human detection.

Unfortunately, however, I didn't particularly prefer the fact that it sends the stream to the cloud and therefore necessarily has to go to the internet to use it, furthermore I noticed a frightening amount of requests in the LAN network so I decided to analyze it and try to enter the internal system (maybe I can modify it and use it freely as I like). For this purpose I disassembled the model and here is the information i found:










The processor seems to be an MSTAR SSC337 (Infinity 6c?) I found some info on this page linux-chenxing && infinity 6. the next step is to connect to the UART on the board and further analyze the software part. Anyone who can help please write

After updating the firmware, there are more false positives.
I want to return to the default firmware at the time of sale.
What is the default firmware version?
After the update, it is [2.800.000000.21.R.240330].

Analyzing the traffic without updating i found this version, I don't know if it can be useful to you.

Thanks for the very interesting info.
