Great tip - rtsp sessions possibly aren't being terminated by the ffmpeg command. That got me investigating other means of recording the rtsp stream that observe session tear downs at the end. I'm currently testing openRTSP. openRTSP -D 1 -c -B 10000000 -b 10000000 -4 -Q -F cam_one -d 1800 -P...

I have a similar problem with the iVMS4500 app giving the error "No more user can be logged in". The camera is a HikVision DS-2CD3132 with V5.4.41 firmware. I have a server continuously recording the main stream for 5 minutes (300 sec) using the following cmd: $ ffmpeg -i...

I have had tftp problems with directly connecting a camera to an Ethernet port on a computer. This was related to power up timing and Ethernet port activation by the OS. The problem is the Ethernet port is dead until there is a device on the other end. It takes the OS a while to recognize and...

Batch Configurator does indeed allow setting ssh access on. But it seems that they have removed the normal bash shell and replaced it with custom commands that are NOT much help. Is there a guide for the new shell commands in the 5.4.x firmware? $ help is not very informative.

Thanks to Alastair, I've been able to recover a bunch of r0 cameras and get them upgraded to 5.4.41 firmware! (Got hacked by backdoor) However, after the upgrade to 5.4.41, ssh access no longer seems available. I can't find where to enable it on the web interface. Any clues? Thanks! Doug

Sounds like the 12VDC connector floats to the camera power supply voltage, but can't supply any current because it would have to go in reverse through a diode. It would be interesting to watch the output voltage as the load increased. But if someone has already tried this, it's not worth the...

Does anyone know if the 12VDC camera connector can be used as an accessory power source from a Hikvision camera when it is receiving power from POE? It does put out 12VDC, center pin positive when POE powered. How much current can be safely drawn from the 12V camera connector? It would be...

try this form page 2 of this discussion. Was posted by whoslooking originally. This worked for me.. Ok this is covered in this post on how to recover your bricked camera this covers all firmwares upto 5.2.8 See this post.http://www.ipcamtalk.com/showthread....brick+recovery.

Excellent point. The brand is being hurt by the current situation. Distribution and branding are a problem when the uninitiated see no difference between a cheap Amazon CH camera that is locked and a "legitimate" supported camera that costs 50-75% more. One way to salvage it would be to...

Yes, I have down graded a camera to 5-2-5-English. I'm just objecting to the fact that CH cameras are banished to single point only solutions and can't join the current software release chain. I guess this is the new normal where companies try to build a moat around their forts.

Thanks!! Now if we can just figure out how to move v5.3.0 CH cameras to US region so that we can get security and capability updates.

Great work and good information! Unfortunate hardware problem. Maybe HIKVision grades cameras on the factory floor and sends non-fatally defective ones to a secondary market at lower cost rather than rework them. It may also be possible that there was a hardware change to improve security...

RS232 access to the DS-2CD2032-I is easy to obtain. See earlier posting in this thread. That gives you console access to the bootloader (Das U-Boot) as well as the root console once Linux boots. From U-Boot, (interrupted by Ctrl+U) one has complete control of the machine. You can tftp load...

For the record, I used hiktools.exe to change the Chinese v5.25 digicap.exe file into English version after updating my mtd5 and 6 to region 1 along with offsetting date string changes. This was done via this command: $ hiktools lang digicap.dav 1. The only changes made to the .dav file were...

Ok, I have the camera recovered back to v5.2.5 with all menus in English. I'm planning to disconnect the rs232 from the camera and put it all back together. My objectives in recovering the camera have been met. Hopefully I've produced some info that will be of use to others to regain control of...

Not sure what is going on. Obviously the error for the pri and sec_part was created before the reboot. Then at reboot, the kernel can't read /dev/ubi1_0. Did they switch to a secure file system?

I managed to "brick" the camera again. I downloaded the Chinese version of 5.3 from the HIKvsions chinese website and upgraded through the maintenance page. Here's the console output. There are probably a lot of clues in there on what is going wrong with the upgrade. Notice that it accepts the...

I actually changed the vendor number from 503 to 504. So the date string went from 2015020503xxxxxx to 2015020504xxxxxx.

Thanks. It was a standing start for the HIKVision, but I've been doing embedded Linux ever since NSLU2 in 2004. I'm actually running Debian 7 now on my 135 MHz NSLU2. I also use Debian exclusively at home.

So I tried upgrading my DS-2032 camera from v5.2.5 to v5.3 via the maintenance page. I checked the digicap-v5.3.dav file with the hiktools.exe utility and it reports region 1. The camera also was region 1 per above mtd5,6 changes. The upgrade to v5.3 failed by refusal. At least the camera was...

I should have been more explicit in the earlier post. The DS-2032 camera is fully working on v5.2.5 in English. I modified mtd5 and 6 to change to Region 1 (English) from region 2. I changed the serial number (date area) to maintain checksum-16. For some strange reason, I wanted to keep the...

OK, I finally got around to editing mtd5 and mtd6 to change the language to English per whoslooking's post. Thanks very much to whoslooking as well as alastairstevenson. The complete camera console log to steady state is attached. Not sure why I'm getting this in the log. start...

Here are disassembly photos and pinout info for the rs232 port of the DS-2032. http://www.cctvforum.com/viewtopic.php?f=19&t=37006&sid=2d97de12796dda691fc4c4e1e803abe2&start=15 See previous page for photos.

I'm still evaluating the situation with my DS-2032. I have rs232 connected, and can also telnet in at times and start ftpd - only if it is booted into the minisystem. I have also been able to run busybox-armv6l (obtained from http://www.busybox.net/downloads/binaries/latest/). The Ambarella A5S...

Yes, u-boot does seem to boot Linux. And it defnitely takes care of the tftp download itself, or it works in conjunction with uITRON before Linux is ever started. Here's a console log when the DS-2032 camera is powered up with the HIKvision tftp server at 192.0.0.128. tftp is taken care of...

See https://gist.github.com/cr3ative/8340001. The Drift HD Ghost "camera also runs on the Ambarella A5S chipset, which appears to run PrKERNEL (implementing uItron): http://www.esol.com/embedded/prkernelv4.html, then boots Linux as a process inside the uItron OS". So if U-Boot is the startup...

It seems that uITRON PrKernel is running underneath everything on the camera. I'll bet uITRON is the system responsible for TFTP boot process that we all use. The PrKernal seems to be in mtdblock2. Does anyone have more information on how all this works? I've heard that Linux runs as a...

If you ping dev.ys7.com it redirects to www.shipin7.com, which seems to be registered to hikvision in china. A browser pointed at dev.ys7.com eventually redirects to http://www.ys7.com, which is hikvision's chinese site.

My working camera (and bricked one as well) has a white label that says it's version v5.2.8_141231. However, the web interface system page reports only 5.2.0. Firmware Version V5.2.0 build 140721 Encoding Version V5.0 build 140714

My working camera (v5.2.8_141231) has the following functions in /bin. tftp does not seem to be available. IPZOOMDebug -> /bin/da_info [ -> busybox [[ -> busybox agingTest -> /bin/da_info ambarella_eth_debug.ko ash -> busybox awk -> busybox bash -> busybox busybox...
