I have a Gold Fortified built home design to withstand a Category 3 hurricane with an 18-foot wide garage door weighing 476 pounds. When a bad hurricane comes my way I have a 1" rigid pipe that I can install in under 5 minutes that will give added wind protection to the center of the door...

On one computer I still use Acronis (single license) but on my other computers, I use AOMEI and it has never failed me yet.

That setup will protect your NVR at the expense of a blown camera and switch. The surge suppressor is great for induced voltage spikes from lightning, but cannot withstand a direct lightning strike. As for the wire connection, I would use a copper split bolt for the connection of the grounds...

Microsoft did away with Internet Explorer. But if you still want to use it, you can download and install "OpenInternetExplorer" from GitHub. Explorer was never erased from your system so "OpenInternetExplorer" permits Internet Explorer to continue to be used. Works for both Windows 10 & 11...

Just be aware that some of the powerline ethernet adapters can trip a Combination arc fault circuit interrupters (CAFCI). I had to get rid of my TP-Link because it would sporadically trip my Siemen's CAFCI 30 amp breaker. So I decided to go with an old router running DD-WRT setup as a wireless...

I would think that since the NVR is running a Linux variant and therefore is formatted with one of the Linux formats. If you are running Windows Subsystem for Linux then you should be able to see the format, or you can boot up with a live distro of Linux to check the drive.

Great job, this should help a lot of newbies. Thank you!

The reason I am asking is that version V4.001.0000006.0 (2021-02-8) on the NVR still requires the Internet Explorer NACL plugin. With IE going on the wayside after June 15, 2022, I, therefore, need to upgrade so that Firefox or Edge fully supports accessing the NVR over the ethernet.

I have a NVR5208-8P-4KS2 (V2) running V4.001.0000006.0 (2021-02-8) and when I click "Manual Check" for new updates it tells me, "You are using the latest version". Okay I know there are later versions available, so why doesn't the NVR say otherwise?

You probably have Windows 11 Home version, other versions will encrypt the drive by default. Windows 11 Home version doesn't include BitLocker https://pureinfotech.com/enable-bitlocker-device-encryption-windows-11-home/

Win 11 requires TPM (Trusted Platform Module) and will automatically encrypt your drive! Having retired from a huge enterprise network system I can tell you the horrors of drive encryption. First off, it will slow down your computer. Second, if your drive were to crash chances are extremely...

I have one of these and it works great for 95% of my troubleshooting. It isn't a "professional" tool, but I used it in troubleshooting large networks, and it is INEXPENSIVE! https://www.ebay.com/itm/294054116773 Here is a youtube showing its use.

Guys, thanks for the great information. BTW, the reason I am asking is that the location is at a remote entrance to a subdivision. I personally have an NVR and 8 IPC-WDW2231R-ZS varifocal cameras around the perimeter of my house, and I favor this setup. I spec'd out a similar setup with 4 new...

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...

Great video!

We required cybersecurity training for all faculty, staff, and students at a large medical school. Training includes an emphasis on phishing techniques used to gain access to our network. Monthly an in-house phishing email is randomly sent out to network users. And without a doubt, there are...

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.

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...

Which version did you previously had on the NVR?

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.

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.

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/

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...

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?

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.

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...

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...

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...

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...

Thank you! That is what I suspected.
