    Dahua VTO2000a with wrong MCU firmware

    VDD was 3.3V in this case.

    TFTP Rescue with signed firmware

    I'd use FW 4.3 since 3.120 was not even signed. All parts need to fit together - very important is off course the bootloader.

    FreePBX with Dahua VTO + 2x VTH

    I've no idea as group_call on vto's works with sip_number+hashtag+device_number only, as far as I understand. So this question doesn't fit here but in a 3cx forum.

    FreePBX with Dahua VTO + 2x VTH

    Just read my posts above in this thread. Setup VTO+VTH with vto sip server like it's described in manuals/video of dauha. Add an extra extension for your pbx on VTO's sip server and activate group_call. Then let your freepbx,etc. register on this server (add a sip trunk from pbx to vto, just...

    FreePBX with Dahua VTO + 2x VTH

    Regarding video from VTO on 3rd pty devices: Have a look at this thread, here we discussed this issue too. I get VTO video on my devices via rtsp (my sip phone is able to connect to a rtsp source) so I don't need sip video for now. Anyway, if you spend some time on that, you might be lucky to...

    FreePBX with Dahua VTO + 2x VTH

    I configured my asterisk (chan_sip) this way: sip.conf: register => 9901#2:password@vto.ip/SIP_VTO extensions.conf: exten => 8001,1,Set(CALLERID(all)="Asterik2VTO" <9901#2>); VTO productive same => n,Dial(SIP/SIP_VTO/${EXTEN}) exten => 9900,1,Set(CALLERID(all)="Asterik2VTH" <9901#2>); VTH...

    FreePBX with Dahua VTO + 2x VTH

    You sould get a INVITE to 9901#2 from VTO - what you do with this in your PBX is up to u. If you route calls to the VTH via your SIP trunk (9901#2), then you should be able to address every single one.

    FreePBX with Dahua VTO + 2x VTH

    Simply setup VTO+VTH according to manual/videos and enable group_call. Add a extra number (e.gh.9901#2) and let Asterisk/FreePBX register a trunk on that number. Then you'll get all (group-)calls on the PBX side as well and can forward, etc. it. Video for clients on the PBX side works either...

    FreePBX with Dahua VTO + 2x VTH

    Set it up with the vto Internal sip server and let freepbx register on that sip server too.

    "Environment Error" on DAHUA VTH2421FB-P during config with VTO2111D-WP

    VDPconfig was included in ConfigTool in dahua toolbox. This works for most devices unless the firmware is not too old (<V4).

    VTO2000A new V4 firmware

    If you run a very old firmware on your VTO2000A-2, you should try to use an older VDPconfig tool to upgrade to V4.3.

    VTH 5221D

    Read out the chip, place correct bootloader at the start-address of the current bootloader and flash it. Then you should be good to start over again.

    VTH 5221D

    No, you are pretty f*****. The only way to recover is to program the flash ic with a external programmer. Did this once, but it is hard for unexperienced users. I suggest to sell the device.

    UART VTH5221D Take an old fw like this one: General_VTH52X1D_Eng_P_V1.000.0000.0.R.20170410 and don't touch the bootloader!!!

    There is a nice thread for this: Dahua easy unbricking Read the 1st post carefully (twice). Then you should be able to get your VTH up again.

    VTH1550CH connects VTO but not cameras (SIP firmware)

    Ok, as mentioned: "hacking" VTO's config might be a workarround for this bug.

    VTH1550CH connects VTO but not cameras (SIP firmware)

    You are absolutely right, bashis! But VTH1550 gen1 is outdated and there is no more support from dahua's side for it.:( All you could try is to upgrade it to the latest firmware I found: General_VTH1550CHW-2_Eng_SIP_V4.300.0000002.0.R.20210720 Maybe you're lucky and the fault has been fixed in...

    VTH1550CH connects VTO but not cameras (SIP firmware)

    Well... Then I'd say, this could be a incompatible setup (at least a bit) :banghead: Maybe there is a chance to hack the VTO's config - can you post VTO's output of "config all"? I'll compare it with my VTO2000A's config, maybe there is chance to convice your VTO to allow some IPC's as well.

    VTH1550CH connects VTO but not cameras (SIP firmware)

    Just gave it a shot with my VTH1660 (same fw binary like your VTH1510) and VTO2000A (latest fw from july '21). No problem. Did you try to add the camera's config again with DahuaConsole or another hack? If they are visible in the config just like they were before, can the camera's be viewed?

    VTH1550CH connects VTO but not cameras (SIP firmware)

    I mean, did you try to add a ip camera again on the VTH AFTER you connected the VTH to the VTO's SIP server?

    VTH1550CH connects VTO but not cameras (SIP firmware)

    @bashis The firmware link you posted is for VTH1550-S2 (2nd. gen of VTH1550 which has complete different hw). Do not try to flash this on a gen1 VTH1550, it will brick it! In fact dahua did not yet release a new fw with a fix for 'Dahua Authentication bypass (CVE-2021-33044, CVE-2021-33045)'...

    VTH1550CH connects VTO but not cameras (SIP firmware)

    That sounds interresting :wtf: Did you try to add the camera's again after you hooked it up the SIP server? Did you also try latest FW for VTO? This seems to be the latest firmware for VTO3211D devices: DH_VTO3211D_MultiLang_PN_SIP_V4.400.0000001.0.R.20210722
