General Discussion / how to connect a dvr to an wifi ipcamera
« Last post by corvairbob on January 13, 2019, 04:18:01 pm »
does anyone here know how to connect a wifi ip cmarea that has a cat5 connection on it to a dvr?

i have a dvr that only has on it for a model h.264 not other information is on it anywhere on the box or on the unit or in the software.

i have my ip camera connected to my network now with the cat5 cable i want to add it to the dvr i have 3 other cameras on the dvr showing on the monitor now.

the back of the dvr has 16 channels they are baulinbcn connections. i have a cat5 coupler and a section of car5 cable with bare wire ends now and i connected them to that adapter and then to channel 2 on the dvr.

the camera is powered up with it's own power supply.

i used the orange/white and orange wires for video fees as a youtube said those wires were what the cameras use for video.

i also tried the other 3 pairs and i tried them both ways. and i still do not get a video picture on my dvr monitor.

so are the wifi ip cameras that have ptz on them able to be seen on a dvr security system?

thanks for any help

Regarde avec un ohmmètre si les connecteurs TP6 et TP4 seraient reliés à J6 DUBUG sur les deux pistes du milieu. Puis test les deux autres pistes pour trouver la terre.

General Discussion / Re: FI9831W - Linux-compatible WebUI?

Hi mbirth,
I'm a newbie of ip cam world, after 2 year and some months my FI9831W as stopped working.

After some search, I've found serial port and I've tried a firmware recovery with u-boot, but with a very bad result.
Now my camera is not booting.
Seems I've overwritten u-boot partition.

Using flashrom sw and Raspberry Pi I can read/write the eeprom but I dont have the image.
Reading your edit I hope You have a backup of image of your camera. :)

I've searched the files section but without success, can you give me eeprom image or a suggestion?

Help / IP Cam Identification Assistance
« Last post by bofh5 on November 27, 2018, 07:30:26 am »
Hello All
I have bought an IP cam but didn't realise it was locked down to an app that uses chinese servers to access it.
It is this one here
I don't think it's a floureon though as it got a firmware update from Yitechnology when i first set it up.
I can access telnet on it using root and no password on port 23
It shows Lobster at the top which i assume is the linux os.
There is no rtsp wo they have crippled it :(
I'm trying to figure out how i can identify if it's a clone of a Yi or something else.
The app it uses is YI IOT
I've tried every bit of software i can find to try and id it but they can't as it's locked down.
Wireshark hasn't been able to help either.
Does anyone know if there is a config file or something that might have more info about the hardware ?
It wasn't expensive so if i brick it i'm not bothered but would like to either flash a replacement firmware or enable rtsp somehow.
Thanks all

I think full crossplatform functionality as a feature is relativly important. Fancy ajax stuff would make it nice and modern since there isn't much space on a 2MB flash unit for fancy graphics though.

What success did you achieve with this camera? I have two myself and hate the firmware on them.
Hacking & Modding / Bricked hi3516c - tried everything
« Last post by russellhq on August 11, 2018, 04:18:27 am »
I bought a hi3516cv300 ip camera from aliexpress, this one:

Plan was to modify it for astronomy use and it was going well until I bricked it  :-[

I first tried to save a copy of the existing firmware using one of those black edition CH341a programmers (again from aliexpress) but I could not get this to work. I tried the CH341a Programmer tool, it would connect to the black edition but would not read the chip (it just returned 16MB of FF ). I tried AsProgrammer and it has similar issues. I also tried flashrom and it wouldn't even connect to the black edition. I carried out the 3.3v mod on the black edition but this didn't work either. So i gave up with this tool.

I next soldered pins to the TX, RX & GND on the camera and was able to get a serial connection running and get into u-boot (the camera did not present a console when boot was complete).

Once in u-boot, I made a copy of the firmware and copied it out with tftp. I did a number of tests to verify the copy worked e.g. using binwalk and also copying the romfs partition and mounting it on my linux machine (all worked ok).

So next was to flash the kernel and rootfs from the SDK, this seemed to go OK, i could still get into u-boot. I changed the boot arguments and was able to load the kernel, but this would crash out at loading the rootfs and I got a kernel panic message. I then decided to go all the way and also load the u-boot image from the sdk as well. This also worked and I got into the sdk u-boot and could load the kernel. This time I got a root access and a terminal connection but rootfs still wasn't loading.

So it was at this point where the brick happened. I had rebooted the device and loaded the kernel and was on the console screen when for some reason I pulled the plug on the camera instead of using the reboot command. The serial screen reset and stayed blank  :-[

I tired unplugging it and leaving it for a while. I checked the power supply. I even tried flashing the firmware backup I made. Nothing seemed to work. The serial connection still just gave a blank screen. There was  some data commming through on power up but that was on about 20 characters of blank text (shown by the cursor moving).

My next move is to desolder the flash chip and see if it can be programmed that way but i'm waiting on some tools arriving.

Is there anything I should try in the meantime to get this camera back up and running?
