Popular A9 mini Wi-Fi camera & the HA challenge

I am trying to hook the popular A9 mini Wi-Fi camera to HA. The problem I find is that this camera does not offer direct customized configuration. The configuration of the camera is limited to be done via a mobile phone using freeware app (no manufacture specific). Out of the box It offers two Wi-Fi connection modes known as hot-spot (direct link between camera and phone) and via Wi-Fi network, e.g. home Wi-Fi network. When using the Wi-Fi network mode I find that the stream is set between the phone and an Internet cloud service, e.g. AWS when using iPhone app Little Stars. Coming to this point I don’t like the idea of having my video stream getting out of my LAN domain.
This is what I have found so far:
-. It makes use of a Beken BK7252 chip
-. The board features JTAG track points
-. It makes use of UDP and interesting enough QUIC too.
-. Sending UDP datagram with payload “Bv” to port 8080 or “0f” to port 8070 triggers the video stream when using the camera in hot-spot mode.
Any one that has reached the goal I’m pursuing or can shed some light on how to move forward?

Googling tells me this camera is crap. Good luck.

I have not been able to prove this sending any data out of LAN on UDP or TCP either. In fact, it looks like it’s clearly p2p traffic.
My take was to pair this up with a phone (unfortunately I managed to do this with Android only as their iOS app ended up being too difficult to work) and see what’s happening.

So here’s what I’ve got going (long, sorry), which I believe is the app init, auth and load up the first few frames:

Now that looks like a traditional http get call, but I wasn’t able to capture any traffic with Charles that’d prove that correct.

Maybe someone looking at more logcats can help making one more step :smiley:

After some further examination, this device is indeed sending some data out to a “cloud”.
It looks like there’s an UDP tunnel created, and communicates with HTTP calls inside that.

While it’s not sending the stream out as is, but it clearly has the capability to do so.

Short traffic dump:

The app connects p2p indeed, and runs this sequence:

  • Am I a valid user?
  • Are you alive camera?
  • Give me stream.

Also, ran into this research: https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html#cloud - while not a full match (given like 4 years passed since), what I’m seeing is very similar.

What a bounty! My intention has been to figure out how to trigger the streaming towards a specific LAN host. This information you have provided is very useful. In my case, I will obviously block the camera for reaching out the public Internet (firewall).

We share the goal of getting this disconnected.
I haven’t tried blocking the connection - does it still work on your phone regardless?

I’m pursuing two options:
a) connect to the stream directly
The option to use anything standard seems to be lost, the longer route is still open however: building a custom client based on the decompiled APK Classes DEX. The resulting code is massive and difficult for me to interpret at the moment.
b) spoof online services - this however may not work as the data going out is not the stream from what it looks like.

When the camera is set in AP mode the stream is sent directly to the phone as both, the phone and camera, are on same Wi-Fi network that is, no stream goes out to the public Internet however, when the camera is hooked to another LAN, then the camera tries to reach out an Amazon service and then the stream gets mirrored down to the phone; the phone will not get the stream if the traffic does not leave the LAN (firewall). It is a shame I did not share all those captures and published them as you did. I’ll try to get something done/sniffed this weekend. I have also tried the jtag option but that area turned out to be extremely experimental to me, no straight reverse engineering method I found.

Oh cool - I haven’t considered the AP mode a viable option on my end as I can hardly see that scale. My idea is to hook this up in front of electricity and gas meters so I can automate a daily reading & actions to nudge the family to be more cautious and think about the environment (lol).

From what I understand there’s auth and device info sent out - that I may be able to spoof around to make the cam believe it’s getting a legit “yeah right” response, but that still leaves grabbing the stream itself hanging.

I’ll be sniffing some more and post details as they come around - while this definitely comes with a terrible ROI for one, the motivation is that should we be able to solve this puzzle, people can save cash as this looks like a great cheap general purpose device.

Looks like this is an A9 v2 board - is this by any chance what you’re looking at on your end?
The chip matches to the description in your initial post - not sure how far we can go with an MCU like this though.

Yours is V2 whilst mine is V1. Layout is similar although no 100% identical. The Belken chip is the same although it seems yours is a newer batch than mine.

I looked into these in January, the only discussion I found of them was on a forum for another home automation product, so I put my findings there: https://www.domoticz.com/forum/viewtopic.php?p=264890#p264890 as well as some code on gitlab: https://gitlab.com/bettse/fake_hopeway

Hi Eric! Welcome to the Home Assistant community.

Do you find opened ports when running nmap? I don’t on mine.

I have found a couple of interesting things:

  1. It seems the camera makes an OTA upgrade. When it boots it requests a rtthread.rbl from http://112.74.76.191/update_jxl_gc0309/rtthread.rbl More info on OTA Downloader: https://github.com/RT-Thread-packages/ota_downloader.
  2. The solution (cam + mobile app) makes use of an external service on the public Internet to bridge the two. Once they get bridged the communication becomes p2p between the two devices. If both are on the same LAN, the camera can be blocked on the firewall and the solution still works.
  3. The camera keeps a heartbeat signal with an external service. If the heartbeat is lost (e.g. camera blocked in the firewall) the camera automatically restarts every third minute. The solution still works.
  4. It seems the purpose of the external service is to configure the application on the phone.
  5. Access to the external service is not necessary once the solution gets bridged. This happens even if the phone and camera have no Internet access (both blocked on the firewall)
  6. If both devices are on the same LAN they communicate using local IP.
  7. All communication between app and cam is UDP.
    8) The cam starts with an ARP request searching for the peer.
    9) Although the app shows Connecting when initiated, it is actually waiting for a sort of “hello” package from the cam sent to port 26807.
  8. The phone starts with a UDP initiation package sent to the camera.

So it seems the key here is to find a way to inform the cam about the IP address to peer with.

The frustration so far:

  1. I do not know the streaming protocol.
  2. The payload is encrypted so I do not know how to simulate the communication with the external service to configure an alternative local IP and to simulate a heartbeat so the camera does not restart.

Hey all! Sorry to wake up such an old post, but I came across this thread while doing some related searches, and I can provide some light in the darkness here:

These cameras use the “PPPP” protocol. You can find a pretty thorough description [here]. Incidentally, that code will also let you examine the packets in human-readable format in wireshark.
Newer cameras use a form of encryption on top of this, using a relatively simple encryption scheme. While I do have full details on how this works, I promised the owner of that git repo (a security researcher) not to disclose that info until he publishes about it first. Older cameras should be using the protocol in plaintext.
If you want to learn more about the protocol (and its security problems), I can recommend [this site + talk]. It also contains some advice on how to use these (and similar) cameras without exposing it to the internet entirely.

I’m writing an extension to some open source software I work on, which will add support for both the encrypted and non-encrypted cameras, both over local network mode and “global P2P” modes, pretty soon! I already have auth, discovery, basic stream settings and retrieving an MJPEG stream completely operational, and am hoping to also get H264 mode working before I release this.

In short: stay tuned, using these without the annoying semi-chinese phone app will be a lot simpler soon. :slightly_smiling_face:

Still not much use for an open source community.

I don’t see how giving the complete documentation of the protocol as well as saying an open source implementation will be landing soon is “not much use”. Perhaps you’re using some obscure definition of “use” that I am not familiar with…?

HI all,
I recently acquired the camera and started to explore the possibilities to add it to HA.
I used Wireshark to check the traffic. Unfortunately, it does not catch it all the time, it depends on the network config. So once Wireshark detected DTLS traffic from the cam. The camera communicates to 4 addresses on the internet, one is NTP server, two are ad advertisements, and don’t know what is the fourth Alibaba IP. Anyway, the fw will prevent that traffic, so I am not worried a lot.
Anyway, I am stuck and I am sharing the Wireshark files in the hope it will help.
Succeeding in connecting this cam to HA will mean a lot to the community.
You can get the Wireshark files in here on Google Drive. If you need more info or help pls contact me

hi guys, some info that I was able to extract from these A9 cameras: if it can help someone smarter than me ....

so to start I have two different cameras, but almost identical with the BK7252 chip which use the "little stars" and "xiaodou" apk.
the printed circuits are slightly different and one of them has RX TX inscriptions. the other D0, CEN, VIO etc ...
I connected a USB-UART converter to RX / TX and launched a terminal (putty or others): I have lots of things displayed!
the system is RT-Thread and I managed to do some cool experiments.
the command "Help" gives all the commands available:

using "setenv" i put my SSID and password, and the camera connected to my network!
 (after a "saveenv" and a reboot.)
  
 On the other hand, still impossible to interact with the camera. an analysis of the TCP / UDP ports does not return anything and Wireshark does not see any frame.
 
 I then created an AP with an ESP8266, to which I added a DNS server which responds to all requests by the IP of my PC.
 I then put the SSID of the AP in the camera + reboot but again I was disappointed because even if the camera considers my PC as its gateway, I do not see any frame with wireshark.
 
 in short, I haven't made much progress and I publish these discoveries for those who, unlike me, know what to do and how to do !!!
 
 sorry for the google translation but i'm french and as you know french only can speak french ...

I’m just here to say thank you to you wonderful smart people for doing this! Bravo! :relaxed:

I’m not technically proficient at all but I so much appreciate and would so much like to have a third party safe app to see this camera from my PC or phone. I want to use it to monitor stuff like faucets or wind drafts etc!) but I don’t like the very weird apps “Little Stars” that makes it operate! Who knows where its sending the feed to! :stuck_out_tongue_closed_eyes:

I got an A9 camera. It has following written on the circuit board (yes I did open and looked so my expertise ends there :grin:)

Thank you again and I look forward to your continued efforts!

I mean I get the technical challenge of reverse engineering stuff, but why do you guys waste your time on garbage like that ?

If you need a small camera that works with RTSP out of the box without RE anything, take a look at these Revotech ones. They look pretty nice, RTSP, ONVIF, PoE, decent lenses, 3MP. Haven’t tried them yet, but thinking of getting the pinhole one as a hidden doorcam.
