    NVR or not NVR, that is the question?

    A friend in the planning stage asked me this question. What is the benefit of going with 4-2MP cameras (IPC-T2231T-ZS-S2) attached to an NVR system that is connected to a cable modem/router? Instead of going with 4-4MP Cameras (Amcrest IP8M-T2499EW-28MM) connected straight to a cable...

    IMPORTANT - Conversion Software for MJP Files

    If you can play the original video, then there is another option that I have used in the past to capture a video stream that I can't or unable to convert. A simple HDMI capture box can capture the video and save it in a common format.

    NVR5216-16P-4KS2E Latest new firmwre NVR5XXX-4KS2_MultiLang_V4.001.0000006.0.R.210208

    I find it amazing that Dahua pushes out firmware that is causing so many problems. I have upgraded firmware on many computers, servers, switches, routers, hard drives, etc., without any problems. Yet something as simple as an NVR running Linux is bricked by an upgrade. Something is terribly...

    Dahua IPC Camera Losing Connection / Re-Connecting

    I have the same problem, but the connection is lost for only a minute or so. It is IPC-HDW2231R-ZS camera. I have checked on connections and have dielectric grease on the connector. The NVR shows a blank space on the recording when this happens.

    DD-WRT anyone?

    I have DD-WRT running on an old Linksys WRT54G router. Since it was impossible to physically run a cable to my NVR, I set it up as a wireless bridge from my NVR to my modem/router.

    Dahua NVR RS232?

    Was the firmware recently updated? The only thing I can find on the forum is these two links. https://ipcamtalk.com/threads/dahua-nvr-update-failed-should-i-be-worried-about-this-error-message.54794/ https://ipcamtalk.com/threads/dhi-nvr5432-16p-4ks2-wont-boot-up-after-upgrade.43490/

    Dahua NVR RS232?

    Does the RS232 port on the back of the Dahua NVRs require a null modem cable or a straight thru RS232 cable? The reason I am asking is I am planning to upgrade the firmware on my NVR5208-8P-4KS2 which is still running version V3.216.0000004.0, Build Date: 2018-12-29. I plan on upgrading using...

    DHI-NVR5432-16P-4KS2 won't boot up after upgrade

    Not sure if I need a null modem or straight thru RS232 cable to connect my laptop to the RS232 port on the back of the NVR? In the picture you show, is it a null modem or straight thru RS232 USB to serial cable?

    Dahua NVR issue

    When you go to playback, do you see that the camera had a recording gap during the same time as your issue? Here is an example of when I temporarily disconnected one of my cameras at 14:14 and 14:58.

    Natural Gas Generators

    I have a 22KW Generac with an automatic transfer switch. It is 2 years old and has been used several times for 4 or 5 days each. Living along the gulf coast (Alabama) a whole house generator is a necessity if you want AC during the summer hurricane. It worked great! It takes about 10 seconds...

    Latest new NVR4XXX-4KS2_MultiLang_ V4.001.0000005.1.R.201126

    seanw7, Thanks for the information. I have a fairly similar setup a 5208-8p-4ks2 with 8 IPC-HDW2231R-ZS cameras. I have been paranoid about updating the system hearing about all of the people bricking their NVR or having functional problems once updated. How do you like the new software...

    NVR Wireless bridge to MoCA

    My Dahua NVR is located in a location which is impossible to run Ethernet cable to my router. So for the past 2 years I have been using an old Linksys WRT54G router with DD-WRT firmware configured as a wireless bridge to my router. This has been working great with more bandwidth and speed than...

    Wireless bridge

    It was impossible to run an ethernet cable to a closet at the far end of the house where my NVR is located. So I had an old Cisco (Linksys) WRT54G (running DD-WRT) setup as a wireless bridge to my main router. It has been flawless for the past year. You can pick these routers up really cheap...

    IPC-HDW2231R-ZS Starlight cameras IR wavelength???

    I couldn't find any information on the IR wavelength for the IPC-HDW2231R-ZS Starlight cameras. Not sure if it is 850nm and 940nm. I am thinking it is 850nm since I can see the red glow of the IR LED when it is on. Any information is greatly appreciated. Nick

    Combination Arc Fault Circuit Breaker tripping

    I wish the manufacturers do a better job in reducing nuisance tripping. I have had 2 circuits that experience this, one of which I was able to solve by installing a RF/EMI filter inline. The other was the powerline adapter that I swapped out for a router. When I was researching my problem I...

    Combination Arc Fault Circuit Breaker tripping

    I kept the CAFCI installed as per recommendation of an electrician. Instead I got rid of the Powerline adapter and now using a old WiFi router configured as a client bridge (DD-WRT firmware). Works great now!!!!

    Dahua added second drive but didn't increase storage or playback capacity

    Well, using the web interface and SmartPSS both showed 0 bytes written to the second drive. I just rebooted the NVR and now the second drive shows that the NVR has been writing data to the drive. Case closed!!!!

    Dahua added second drive but didn't increase storage or playback capacity

    Attached is the Record page. I am running V3.216.0000004.0, Build Date: 2018-12-29. As a retired IT Analyst, I believe in "if it ain't broken, don't try to fix it". I always wait before leaping into new firmware unless there is a real security reason to do so.

    Dahua added second drive but didn't increase storage or playback capacity

    I thought since I allocated four of the eight cameras to second hard disk (group 2) as in the first attachment above, they would start writing to the second drive.

    Dahua added second drive but didn't increase storage or playback capacity

    I added another 4TB drive to my Dahua NVR5208-8P-4KS2 and everything is functioning. But I noticed several days later that the recording on the second drive is still 0/4TB and the playback capacity is still about 12 or 13 days ( 8 2MP IPC-HDW2231R-ZS cameras h.256). Attached are the screen...
