Post 5 messages, and the restriction is lifted,  its a spammer block, unfortunately if you don't make it difficult then the boards get inundated with spam.

I have removed some of the non relevant questions (the ones related to the older forum template).

Firmware / VACRON firmware format
« Last post by temp0727 on Today at 05:12:16 am »
Hi,

I have this IP camera from VACRON.com, I checked their firmware and couldn't find anything about it. I mean it either encypted or compressed.

Suppose it's possible to unpack/decrypt firmware. Would it be possible to modify the linux inside it and upload it back?

Hi,
Sorry I didn't get a notice of this reply until I happened back here to research!   That is a lot of info to process!  It certainly looks like there's a lot to learn!  Isn't there an option to use "pelco" protocol which addresses this directly (without having to "hack" anything?).  Also, I picked this camera board specifically due to it's diminutive size on a single board (32mm x 32mm).  If there are any more appropriate camera boards which are of this size or smaller I would be very interested in buying one of those instead!
Thanks!

ps.  It seems to be drastically difficult to post responses here as I have first a captcha, and then three additional questions, at least one of which is very difficult/ambiguous to answer.  For example:  "What number comes before Yan An Zhong lu in the address? (use numbers):"   What- the URL address?  The mailing address?   Nothing is listed here on this page or the home page of the site.  I have to repost this until I get a manageable question and this seems to happen each time even though I'm logged in!

Site Announcements / Forum, software updates
« Last post by admin on July 14, 2017, 03:20:24 am »
Updated forum software to 2.0.14, changed default template to the traditional default, as I need to work on the old template to make it compatible.

Added some boards for the XiaoMi camera range, as I have some, and will probably fiddle with them!

Xiaoyi Camera (小蚁) / Region lock fix
« Last post by admin on July 14, 2017, 03:08:48 am »
From my page here - http://www.computersolutions.cn/blog/2016/09/xiaomi-camera-bs-region-locking-fix/

Essentially -

Enable telnet.
Login.
Kill the watchdog, and kill the camera app.
rename the api call to check the country.

-----
Create a folder named test on an SD card.
Create a plain text file called equip_test.sh in that folder, and add the following bash script:

Code: [Select]
#!/bin/sh
# Telnet
if [ ! -f "/etc/init.d/S88telnet" ]; then
echo "#!/bin/sh" > /etc/init.d/S88telnet
echo "telnetd &" >> /etc/init.d/S88telnet
chmod 755 /etc/init.d/S88telnet
fi
dr=`dirname $0`
# fix bootcycle
mv $dr/equip_test.sh $dr/equip_test.sh.moved
reboot

The script will enable telnet on the camera, and then rename the script so it doesn’t run again on the next boot.

Stick the prepared card into the camera, power on, and it should reboot (twice).
If you check the open ports on the camera ip you should now see port 23 (telnet) is open.

Login with the default user/pass (as below) via telnet

User: root
Password: 1234qwer

Once telnet’d in, enter the following, line by line –

Find and kill the watchdog process

killall watch_process

Find and kill /home/cloud process so we can edit it without the watchdog watch_process restarting it

killall cloud

Change the check within /home/cloud executable to query a fake domain so it never returns a failure, then reboot.


Code: [Select]
sed -i 's|api.xiaoyi.com/v4/ipc/check_did|api.xiaoyi.foo/v4/ipc/check_did|g' /home/cloud
reboot

Really depends on the board you have, and what gpio's are available to use, and how much flash / ram (for user space software etc).

Do you have the Hi3518e SoC SDK?

You'll need the SDK to get started, and compile a rom with kernel, userfs etc
Maybe the supplier will give you a ready to use kernel/rom/userfs that you can start from.

You'll need to have a  uBoot on the board.  Hopefully will have one already, otherwise you'll also need an SPI flash programmer to program the uBoot.
You'll need to be able to setup a crosscompiler environment (suggest use Docker or similar virtualized system to setup, then you can migrate easily).
You'll need to unpack the SDK, then be able to compile kernel.
You'll need to learn how to setup rom in flash.

Suggest read the uCLinux posts from 2011 where I talk about similar things.  Its relevant, although not 100% relevant to your particular board.


Also suggest reading other peoples posts, e.g. https://felipe.astroza.cl/hacking-hi3518-based-ip-camera/

Good luck.

Might want to think about using something like an ESP8266 for your gimbal to control sensors, as that has wifi, and they're dirt cheap.
