    (2) NVR’s different networks recording the same camera

    You could do that but you will have to add the cams separately on the second NVR and turn off the switch addressing. or the cams will get confused as to which NVR is master. This used to work, I'm not sure if it still does tho, if port isolation has been turned on it wont. You'd have to...

    (2) NVR’s different networks recording the same camera

    A few ways to do it 1) VPN(or router open ports) between the two business routers over the internet. Add the 2 cams as streams from NVR 1 to NVR 2 - same as you would add an IPC. Limited control over the IPC settings from NV2, potentially a good thing. 2) Put the two cams on their own PoE and...

    Dahua PTZ vs motor lifespan

    Ah yes, found a thread from 2021 with Speed666 resetting it. Well if it happens to my not really a PTZ SD2 model then I'll take a look. But so far the stats are pretty minimal but interestingly most of them were hidden on the page by Javascript.

    Dahua PTZ vs motor lifespan

    I was aware of a message pop up to say something like "movement overtime" or other Chinglish, but you're saying that it actually stops the PTZ function from working at all ? Do you have any which are doing this ?

    Add remote cam to NVR with SN instead of IP address

    Longer answer yes. But you have to ask Dahua for custom firmware to add in the auto register SERVER function into the NVR. If your project if big enough they will consider it.

    Dahua SD1A404XB-GNR questions/setup

    Not sure if you see this smear in both day and night modes. If it's night time and you pan the camera around and the smear is still there it rules out the hemisphere. If you switch to BW during day time and the smear appears then it's potentially a mark on the sensor or lens as the LED's...

    What camera for monitoring front of server racks

    It's arguable that it was by design as APC was also in the business of selling very over priced battery packs. The good old days of IT being as many free UPS as I could carry, only that they all needed new batteries and some needed full disassembly to remove them! I personally never saw one on...

    Dahua Cameras with a Hikvision NVR

    I knew there would be a good reason for the pain :) Thing about the app is no benefits to any manufacture to not promote lock in and any 3rd party writing one would have no revenue stream. it's only getting more complex with analytics etc and needing to speak to the API's so yep, unlikely.

    Dahua Cameras with a Hikvision NVR

    I'm sure you've got a good reason to go through all this pain when a new basic dahua recorder is around £100 ?

    How to fix Ethernet Cable on Dahua Cam [IPC HFW-5442E-ZE]?

    When I'm terminating RJ45's I always backfill the connector with quick drying silicone. It helps to waterproof but also helps on strain relief and wire pull out.

    Send http request if alarm [Dahua IPC-HFW5442E-ZE]

    Oh I like that, you aren't even bothering to read the email just the act of sending it. Hmm. You could possibly be even more efficient by just looking for the connection attempt from the IPC and dropping it than going through SMTP motions.

    Dahua SD1A404XB-GNR questions/setup

    The haze could be IR reflection. Point it in another direction for a test. If you want to do a day/night comparison to find any hardware issues, dont move the camear between shots !!

    How to fix Ethernet Cable on Dahua Cam [IPC HFW-5442E-ZE]?

    Is for putting over the cable before terminating it so it doesn't work well with pre-terminated cables. Also you are missing the rubber O ring from the camera side cable which sits on the lip below the "thread" section. Self amalgamating tape does well in these cases. For the junction box, if...

    I cannot connect to a new Dahua camera

    Some browser sometimes have a nasty habit of remembering some session variables when you reboot a NVR or IPC. The best thing to do is close the browser and open it up again just to refresh those things. Some times a new tab will work, sometimes not.

    How to view Dahua cameras without browser plugins

    Just a "you really dont know how bad it could be" post. I've got an old lantronics serial to ethernet covertor I'm trying to setup for a project. It uses java for the web interface. Have you tried to use java recently??? I've had to install a windowsXP VM and use oldversion.com to get an old...

    (2) NVR’s different networks recording the same camera

    You've said little about the LAN side of things so it's not easy to figure out what's going on and make a recommendation. If both recorders LAN ports (assume they are twin NIC NVR's, not one NIC with built in switch?) are part of the same network and the cams are also on it, then no problem...

    2022 New M20 Thermal Protable Camera

    Dahua never owned FLIR. Dahua bought parts of FLIR which FLIR had bought themselves eg: Lorex. FLIR did some OEM and arguably lessened the brand name - probably up til the point that someone in govt mentioned playing with chinese "toys" might affect military contracts. <Cough> NDAA. No doubt...

    Send http request if alarm [Dahua IPC-HFW5442E-ZE]

    Not a web request per say you are going to have to play with python to get functionality out of it, but alarm center function will send out a message and you can turn it on/off in most if not all events. Lack of documentation means your first python program is just going to listen on a port to...

    What camera for monitoring front of server racks

    This is likely overkill and expensive but it is intended for scenarios such as yours: https://www.dahuasecurity.com/products/All-Products/Thermal-Cameras/Thermography-Series/Thermography/TPC-KF2241-T At least it would help you monitor the temperatures / overheating / fire as backup.

    2022 Latest New Dual-Channel Camera

    It will read a plate as part of metadata like other #7 cams do, but like them doesn't provide the data in the same way as an ITC model to the backend NVR/VMS. It looks like the idea is to have a zoomed in view to make a better go of analytics whilst having an overview stream as well, without...

    Dahua IPC-HDBW4120E IP cam refuses connection on all normal ports (23, 80, 443, 37777, 37778)

    Monitor it's mac with wireshark and power it on/off you should see several broadcasts for various things. If you dont, then it's sometimes an indication of it being stuck in bootloader. ie: broken (with some hope of resurrecting it if the flash isn't fubar) FYI: Many cams come with a fly lead...

    Any documentation on ITCPUSH used by DAHUA ALPR camera

    It's possibly for custom applications, noting that the char set is GB2312 or UTF8. You could try writing some python to accept the connection and debug it that way.

    Protocol DH-SD Pelco-P/D (auto recognition)

    Someone jump in and correct me, but this is a left over from some of the models which have a 485 interface as they will let you control them via 485 telem, be it dahua protocol or Pelco. The wires for 485 might not be fitted to this model, but there is a good chance it's still exposed on the...

    Dahua nvr5216-16p-4ks2e defaults random camera names after reboot

    I have this problem too on a unit but some cams are Dahua, some are an OEM and some are in ONVIF mode. The ones which never fail are Dahua. The always fail on reboot are ONVIF and the sometimes fail every 3-4reboots are an OEM. So what cams are connected ? Genuine Dahua not grey market?

    Amazon UK Customers are going to be pissed

    It's VISA's stated aim to replace physical cash, and everything they do is geared towards that goal. Not just a case of "hey we'd like you to use plastic" but actively disrupting and lobbying against cash. Cannot support that in any possible way.

    External, independent control of Dahua IR LEDs and Alarm output via API

    With the older style IR LEDS which were a ring of what I'll call standard looking ones, just opening the cam and bending each one towards the outside of the circle would fix the spot light issue somewhat. With SMD ones, a little solder heat and bending does the same thing depending on the...
