Hello, I'm blocked trying to configure my NVR & 4G router to allow remote access from gdmss app. I discovered that my provider blocks inbound traffic (port forwarding does not work: I tried to configure port forwarding + ddns on my Huawei B315 but unable to see open ports from a remote...

The good news are that my cams came back to life! The first one was not recognized anymore by the NVR but by connecting my PC directly on the NVR (and changing IP config to belong to the same subnet), I reached the camera then reinstalled the firmware (took the excellent kit provided by...

Hum strange, hope we've not been hacked. Mine is connected on a dahua NVR. I never updated the firmware (advice of the seller). I also used configtool to try detecting them. Sometimes, the cams appear in the list and sometimes not. Unable to connect through configtool. I tried to unmount but...

Hello, I experience an issue with my 2 4431C-A (connected to a NVR4208-8P-4K) 4. They are working since last year without any trouble. And one day, the cam is no longer detected by the NVR, and impossible to connect on it directly. The infrared DEL is on but the system has crashed. I never...

Thanks a lot for this link. Do you know how the sellers translate those firmwares to English ? Can we do the same with the last firmwares ?

Where can we find firmwares for our Chinese 4431C-A?

Hi, Following recommendations of this thread, I configured both day and night profiles of my 4431C-A cam. Nevertheless, I'm wondering how to switch automatically from one to the other profile. In the menu, there are 3 options: Normal, full time, schedule. Apart schedule, it seems there's no way...

I played with image settings directly on the cam and finally went to the conclusion that config1 on NVR corresponds to day, config2 to night and config3 to normal !

Ok found my error. Thr first time you enable Telnet through web browser, a pop up window requests login and password. This first login is admin and the normal admin password. Then when using telnet, have to use 7ujMko0<Password>. Works great now! Thank you Nayr.

Strange, 4421d still available on international web site. Maybe sellers push to sell Chinese stuff!

I tried to do so directly to my 4208-4K NVR ... But I'm maybe wrong ... Work only for cams? PS/ Nayr I see that you own both HFW4421D-AS 4MP and HFW4431M-AS-I2 4MP. I just created a thread to help me choosing between the two, if you have time to help...

Hi, Do you know what's the difference between these 2 models ? I cannot find HFW4431M-AS-I2 on international website, only the 4421D.

Tried to do so and get an error: "Error ErrorID=0, Detail=Invalid Authority!"

I don't understand me too, attached a screenshot:

I wake up this thread, I installed my Dahua NVR and some ethernet cables on the roof of my house. Considering my request and your comments, I'd probably go to a cam without PTZ ... (because of the money and reliability uncertainty of the cheapest models I considered such as Huisun, Sunba ...)...

Hi everyone, is one of you using this model with a NVR ?

Thank you for your answers. As nayr said, the NVR has its own POE switch with IP addressing different from my LAN. I folllowed nayr recommendations: connected my laptop to a POE port of the NVR, configured the IP address of the laptop within the POE switch range and then accessed the cam through...

Just received HDW4431C-A and NVR 4208-8P-4K and work well!

Hello, First of all thanks for this useful information! I'm playing with a 4431C-A and try to apply these settings. My cam is connected to a Dahua 4208-8P-4K NVR and I was wondering how you can change automatically the night / day profile according to time or day light ... I don't see such...

Hi, I just received my 4208-8p-4K NVR and IPC-HDW4431C-A, so everything from Dahua. Everything works great and I'm now playing with fine tuning. Regarding the settings of the image quality, do I need to remotely connect to the IP cam or everything is available through the NVR HMI ? If yes, how...

I answer myself ... in fact I needed to go in Storage > Snapshot and change from Continuous to Motion No I get one snapshot attached to my emails. Wonderful NVR ! I also changed smtp to port 465 (but not sure it changes anything).

Hi, I just received my Dahua NVR DH-NVR4208-8P-4K and I'm playing with motion detection, alerts ... I activated emails (smtp.gmail.com on port 587, encryption TLS, activated attachment check box) but I don't receive snapshots attached with the emails. I receive emails but without attachements...

Thanks a lot for all your messages. To be more precise, I envisage to install a door station at the gate (dahua has one with a 1.3MP cam) but I'm pretty sure it won't be able to record the whole zone (and not sure the cam able to record if door station not activated). Regarding installing a...

Thank you, I didn't know this serie. Nothing better than 2MP? I already had a look on Huisun, but I don't know if this model is compatible with Dahua NVRs. And the reliability is a problem, you're right.

Thx Del Boy, appreciated! Which affordable model do you advise?

~58m (190ft) from the gate to the base of the red point. I don't need to go through the gate, but for example people looking at my house at the gate level or people entering on the way if the gate is open.

Hello, I'm building an IP cams surv system and I need your help to choose the right cam to keep a look on the path going to my house. The cam will be fixed at the corner of my house (see the red point on the picture below). The path length is around 58 m (190ft). I think I don't need a PTZ...

Thx for your feedback. I was also considering a hik one but this one seems to be cheaper (and dahua cams too) Envoyé de mon A0001 en utilisant Tapatalk

Hello, I'm considering to buy this NVR on Ali. A pure Newbie question ... Do I need to connect it to a TV through HDMI ? All my network cables arrive in my garage, so the NVR will be there. Any feedback on this NVR ? I was initially considering to use my server instead of NVR but I'd prefer to...
