    Dahua NVR and camera IP addresses

    An update.... the firmware redo did not improve the CAM Offline issue. I did reduce the channel width from 40Mhz down to 20Mhz but it is unclear if that helped. For the first time in two months only one camera went offline today. It has always been both cameras. The last time the two cameras...

    Dahua NVR and camera IP addresses

    Yes I wondered if that was the case but that is for all cameras. Since only the two 4MP 5442 cams were going through the router to the NVR I guessed the router was only processing (2x4)/((2x4)+(8x6)+8)MP = 12.5% x 68Mbps = 8.5Mbps. The 8.5Mbps seems minimal to me but I'm far from an expert. Are...

    Dahua NVR and camera IP addresses

    Update.... the increased dBm power of the two Ubiquiti antennas did not fix the "CAM Offline Alarm" issue. Tomorrow I'll redo the firmware upgrade on the two 5442 cameras. The NVR/monitor GUI Camera List page shows the "Remaining Bandwidth / Total Bandwidth" as 100Mbps/168Mbps. The two 4MP...

    Dahua NVR and camera IP addresses

    Thanks wittaj, I think that's a great idea. I'll call the switch 100m away with two cameras switch A and the new switch you are suggesting as switch B. The NVR has several cameras connected directly into its PoE ports. Switch A and the NVR are connected to switch B and switch B connects to the...

    Dahua NVR and camera IP addresses

    The modem is a TP-Link Archer AC1200 MR600. I don't see a "switch rating" on the datasheet but the ports are labelled "Gigabit LANs" and the datasheet says "Ports: 1 10/100/1000 Mbps LAN/WAN + 3 10/100/1000 LANs". The "CAM Offline Alarm" alert has only started since I did a firmware upgrade on...

    Dahua NVR and camera IP addresses

    I keep my NVR and cameras on a stand alone network. My Dahua 4216 16 PoE port NVR NIC is 192.168.2.108 with gateway 192.168.2.1. The NVR is connected to a 4G wireless modem/router. Several Dahua cameras are connected directly into the PoE ports and the NVR automatically assigned them IPs in the...

    How to replace the Dahua NVR buzzer with different sound

    Yes, it's on the max. Yes, they are only on the NVR. I think my current issue is that I can't even "play" the sound file via the Audio screen when ticking the "play" button. Edit: I'm wrong. I can just hear the sound file when I hit "play". The speaker has so much interference, however, that...

    How to replace the Dahua NVR buzzer with different sound

    That didn't work and I tried each of the RCA sockets on the NVR with the single RCA plug on the speaker. Interestingly, when I click "Play" on a ticked .mp3 file in in the /Audio/File Management/ screen on the attached monitor, nothing happens either. The file is only 50KB so is within the...

    How to replace the Dahua NVR buzzer with different sound

    Yes, sorry, I didn't mean to physically replace it - just replace its sound with another. Ahhh, I had wondered if that was the case. I'll buy a speaker and try it out. Thanks for the reply.

    How to replace the Dahua NVR buzzer with different sound

    The buzzer on my Dahua NVR4216-16P-4KS2 sounds exactly like a local bird so I never know whether its an alarm event on the NVR that has just sounded or if it is a bird. How can I replace the default buzzer (which is more like a "beep, beep") with something more distinct. I can turn the alarm...

    Slow, unuseable OpenVPN connection to Dahua NVR

    Network layout about as simple as it can get.... It's a NVR4216-16P, TP Link MR600 4G modem, one of two laptops (either Lenovo Intel Core i5 8th gen or Leader Core i7 10th gen). NVR: network port cat5e cabled direct to LAN1 port of modem. modem: LAN/WAN port cat5 (or cat6a) cabled to ethernet...

    Slow, unuseable OpenVPN connection to Dahua NVR

    I've also bypassed the WIFI connection (and not used OpenVPN) and connected to the modem by ethernet cable. This still results in a playback which starts but is either extremely slow or hangs a couple of seconds into the playback. I'm using an ethernet/USB convertor since my laptop does not have...

    Slow, unuseable OpenVPN connection to Dahua NVR

    Yes, it is set up to stream sub streams (704x576). By the way, I'm using SmartPSS on my laptop to access the NVR. I've tried accessing the NVR through the WIFI modem attached to it (WIFI on the laptop and without using OpenVPN on the laptop) but even a one camera live view results in the...

    Slow, unuseable OpenVPN connection to Dahua NVR

    At home I have a Dahua 4216-16P NVR, cabled to a TP Link 4G mobile broadband modem, a static/fixed IP address for the modem and running OpenVPN on the modem. Only the NVR is on this mini network. I have OpenVPN installed on my laptop and I can connect to my home NVR with my laptop from outside...

    Advice on Dahua Cameras

    The viewing angles are usually on the datasheet for the camera. I get the datasheets from www.dahuasecurity.com and then also search Youtube for some reviews and examples. I installed all my Cat5e cabling on the outside wall of my house since I also don't like WIFI cameras. I recommend you find...

    Dahua 4216-16P NVR questions on new setup

    Okay, three more questions: Yes I've done both of those and hence my preference for the NVR/monitor/mouse option. SmartPSS has a slow response time on my laptop, I find the font size is far too small and the playback is inefficient compared to the NVR/monitor/mouse option. As for playback...

    Which camera to "Observe" someone 40m away?

    I have eight HDW3641 2.8mm cameras surrounding my house which seem to do a good job of detecting people (I use IVS "intrusion" settings) any closer than 20m to the house. Now I'd like to install a camera on my house which can observe a person snooping around my shed which is 40m away from the...

    Dahua 4216-16P NVR questions on new setup

    Another question... I've added several cameras to the NVR by simply plugging in to the NVR and waiting. I've also setup Intrusion zones on all cameras via the NVR's web GUI via Internet Explorer on my laptop. Thanks go to bigredfish for his handy tips in the thread "***PSA for those with a New...

    Dahua 4216-16P NVR questions on new setup

    The NVR manual and other internet search results only use the enabling of P2P on the NVR to set up remote NVR access via the gDMSS app. The "Add Mode" field on my gDMSS app's "Add Device" page also only has the "P2P" option. I see, however, the recommendation from knowledgeable people on this...

    Dahua 4216-16P NVR questions on new setup

    A couple of queries from a newbie: (1) after I've finished experimenting with camera setups, recording, etc I'd like to delete all the test video clips prior to going "live" so to speak. How can I do this in SmartPSS or the NVR interface? (2) I can locate the camera "overlay" options in the NVR...

    Can a Dahua NVR be mounted vertically?

    Couldn't find anything in the 4216-16P NVR manual I downloaded from Dahua. I'm wondering if in my case it would be easier to mount the NVR vertically against a wall. Air circulation would probably be better but the HDD may not like being vertical. I could also more securely bolt the NVR to the...

    ***PSA for those with a New DAHUA NVR with Built-in PoE switch

    Yes I did that, as advised. Twice, with slightly different IP addresses. Didn't work for me but I'm no expert either so I could have made a mistake somewhere.

    ***PSA for those with a New DAHUA NVR with Built-in PoE switch

    Update.... I took an old modem (no SIM card inserted so no internet access), connected the NVR to one of its LAN ports, connected the laptop to another of its LAN ports, disconnected my laptop's WIFI connection to my home modem, started Internet Explorer, entered the NVR's IP address in the URL...

    ***PSA for those with a New DAHUA NVR with Built-in PoE switch

    MS Windows 10, latest update on a laptop with core i7 10th gen CPU. I also did a network reset via Settings/Network/Status but all that did was screw up my WIFI link between my laptop and the mobile broadband modem. (Although I don't need/want the modem in order to use the NVR I'm now busy...

    ***PSA for those with a New DAHUA NVR with Built-in PoE switch

    Yes, just tried it but no success. I did not have a choice to leave the default gateway blank. I had to enter something before I could save the changes. I just entered the same details I see on the NVR interface plus a "subnet prefix length" of 24.

    ***PSA for those with a New DAHUA NVR with Built-in PoE switch

    Thanks for the prompt replies. The NVR is not connected to anything - except my laptop via the ethernet cable. I intend to keep the NVR separate from my home WIFI network by using another 4G wireless broadband modem. That is: two modems. One modem for "home" use for family laptops, etc and...

    ***PSA for those with a New DAHUA NVR with Built-in PoE switch

    I followed the guide (way back on the first page, step 1) to set up my 4216-16P NVR and all is well. I kept the default IP addresses, changed nothing, etc and logged out of the NVR interface. I've already downloaded SmartPSS on my laptop and planned to use that the continue exploring the NVR...
