Which CCTV systems will interchange with a Dahua system?

[QuattroZ]

If I removed my Dahua NVR and cameras could I fit a Hikvision system without changing the cabling?Which other system would plug straight in?
I currently have a DH-NVR4208-8P-I with 5 DH-IPC-HD3849H-AS-PV cameras, one of which no longer sounds or flashes at night, although the white light comes on. The search mode shows a virtually blacked out image after I enter the intrusion zone. I can just about make out my image. When leaving the intrusion zone, I get a brief colour glimpse of my exit. Another camera won't trigger in the dark
This happens in both armed and disarmed periods.
The system works during daylight, and the buzzers in the nvr sound when each intrusion zone is entered.
This system was installed less than 2 months ago.

The cabling would be the same.

But the issue is your setup and changing an NVR to a different brand will not help.

It is best to match camera and NVR brand for full functionality.

For example, you have TIOC cameras, so almost every setting associated with that will not be available in a different brand NVR.

ONVIF allows for the camera feed to work with a different NVR that is ONVIF compliant, but outside of the video no guarantee anything else will work properly.

It sounds like your camera setup is wrong and either shutter too fast or it is not set for lights to come on.

Further, it is well documented in this forum how bad that camera is.

This thread has links to few of those threads:

Well that explains that then, that would make sense I suppose, light stays off when dark, not even IR, then when movement or an image is needed it turns on the led and stays on until it's light enough around it and turns off.

Well that's just great! Thought the 8mp would be an upgrade to my 5 mp cams, in the day yes, night not so sure. It's off or it on!
Really appreciate your time mate

Sadly, you have fallen for the chasing MP trap. Are you able to return them?

You want cameras with MP/sensors in GREEN.

5 DH-IPC-HD3849H-AS-PV cameras, one of which no longer sounds or flashes at night, although the white light comes on.

If 4 work OK consider performing a hard reset and re-setup of the non-working camera.

This system was installed less than 2 months ago.

And the company or person that performed the install and setup offers no performance warranty?

You dont have the knowledge you need to operate your system. You need to educate yourself, asking here is a great first step, congrats.

But throwing away a system because of that isnt going to help.

All IP camera systems operate on the same Ethernet cables

You didn't wrote what versions of cams You have (-S4, -S5).
But this should work. If not, something is wrong configured.

If this system was installed by some CCTV installer - then You should simply call him and report that something is not work.
If You can't do that, then it's time to learn how to configure this system.

Thanks Wittaj. I am trying to get my money back so I can buy HiKVision kit..

Hi Steve. I have the data sheets for the camera, and there is no indication as to whether it's -S4 or -S5. It is called Wiz Sense DH-IPC-HDW3849H-AS-PV 8MP Full color Active Deterrence Fixed-focal Eyeball WizSense Network Camera. As I said to Wittaj, I am in the process of trying to return it and get a refund. The installer got very upset when I went into the Admin and had a look at the settings - he said his company doesn't usually allow customers full permission to access the buzzers and bells sections I contacted the Dahua Support people in Maidenhead ( I live in the UK ) and eventually they stopped answering my emails. Some support!! I did find a manual from 2021 which contained data for the NVR, but other than that the nearest model I can find is DH-NVR4208-8P-EI.

 

[wittaj]

I don't mean to be mean, but as others have mentioned, you seem to not have the knowledge of how to use the system and and you made changes to things you didn't know what they did and now you have a problem.

Switching to Hikvision will result in more of the same, if not worse, as many feel their userface is horrible and not as easy as Dahua.

Many people have bought a "Hikvision" or "Dahua" and call or email Hikvision or Dahua for support and they basically tell them to go pound salt - we have dozens of threads were people come here after trying that route. We simply are not their intended market to sell to and they will not take your call for support...Lot's of threads here confirming this, including one from a few months ago where someone tried to call for support and they told them sorry talk to your installer. Which is exactly what they are telling you.

Hikvision will be the same way.

Your best bet would be to learn about the system or have the installer fix it for you. Simply changing out to Hikvision will not solve your problem.

We can help you learn the system. Post screenshots of the settings of the cameras and we can tell you what is wrong.

 

[QuattroZ]

You are right - I don't know the whole system, but the only thing I changed recently was the admin password. I'd had a couple of illegal logins, and the advice from the manual is to regularly change password and username. I am basically the administrator so I left that unchanged .I don't know how to take screenshots from a Dahua monitor.Trial photo of : Camera list ;

 

[QuattroZ]

The cameras appear to Delta-opti: This is the instruction manual Delta-Opti Instruction-IPC-HDW3849H-AS-PV-0280B-S4-BLACK.
Which area of the Camera data is of interest to you? As far as I can see apart from the port settings for Cams 2 and 4 they all appear to have identical settings.
Have you a facility for reading the config file? In text format it is gibberish.

 

[wittaj]

Based on what you said, it sounds like you changed the profile and shutter speed and the lighting settings, along with possibly some schedules.

And if you made the changes from the NVR connected to a monitor instead of the NVR GUI, that compounds the problem.

Best practice is and continues to be accessing the camera GUI via a web browser.

To get into the camera GUI from the NVR, you need to first access the NVR GUI by going to a computer and opening up a browser (preferably Internet Explorer (yeah we know) but Pale Moon will work as well) and type in the IP address of the NVR and login that way. Next go into the camera settings page on the NVR and look for the Microsoft e Web Browser and select it and it will go to the camera GUI (photo credit bigredfish from his PSA thread). Your screen may look a little different to get into the camera gui and see if doing it this way gets you access to some other features the NVR is blocking - do not worry about the Port number and circle as that was from another issue someone posted.

Much simpler than disconnecting the camera from the back of the NVR and hooking it to a POE switch and using IPConfigTool to temporarily change the IP address to your subnet to log into the camera GUI and then reverse it to plug it back in to the NVR.

The user/pw should be the same as the NVR unless YOU changed the camera user/pw.


How to enable native Internet Explorer in Windows 10 and 11:

• Open Notepad:
  • Copy then paste the single line of code below into Notepad:
  • CreateObject("InternetExplorer.Application").Visible=true
  • Save as OpenIE.vbs
• Make sure the the file name ends in .vbs not .txt, If it ends in .txt you must rename to .vbs
• Create a shortcut to the above file and double-click it anytime you want native Internet Explorer.

"Based on what you said, it sounds like you changed the profile and shutter speed and the lighting settings, along with possibly some schedules".

This is interesting. The camera which blacks out is mounted under the eaves of my garage, about 11feet from the ground and points down the garden. Long before the system was fitted, I burned my garden rubbish about 14 feet from the wall of the garage. This puts the camera lens about 17 feet from the fire.
I continued having fires . After dark, the embers still glow, and looking at that camera's image, I did notice a couple of white spots where the fire was - this was via the IR. I spoke to a guy who sells Hikvision , and asked him whether the heat would affect the IR sensor, and he mentioned that the camera may have reset itself .
This camera is on 37777 as the other camera on the garage, which is about 40feet from the house. The link to the nvr is via a dedicated wireless transmitter and receiver.
The other problem is that the nvr tees into the network cable between my computer and the router, and I can no longer see the router on my computer. This was done by the installer.
The router is connected to my wifes computer in another room, so I was on her network.
I cannot see the nvr on my computer.
I have not changed any camera passwords.I know my limitations.
You can see from the photo in my last but one post that my current Camera screen is different from the one in your latest post.
Incidentally I have just received notification of a system update which was bug fix. It didn't change anything in the setup. I have looked on my wife's computer network and there's nothing which tells me an nvr is connected.
In the attachment is part of the list of illegal logins I get.
I have had alook at the details of the DH-NVR4208-8P-EI which appears to be identical to the DH-NVR4208-8P-I. What's changed I ask myself.

 

[wittaj]

Heat wouldn't have reset the camera. If it did, it would revert back to auto/default settings which would give you a bright static image at the cost of blur with motion....Hikvision guy is giving you a line of bull....

So the picture you posted is from the NVR connected to the a monitor and not via a computer and the NVR GUI via Internet Explorer - that is why the screens look different. You have access to way more stuff logging into the NVR via a web browser than you do connected to a monitor.

Depending on how you changed the NVR password, that may or may not have been passed on to the cameras, so the cameras now may have the old NVR password, the new password you gave it, or maybe the installer used a completely different password since you are not using the POE ports for every camera. Who knows at this point.

Now we find out you have networking issues that the installer did by making changes and you say you can't see the NVR on the network.

You have issues that simply replacing the system with Hikvision won't help at all and would probably be even worse at this point. You need to learn some basic networking or bring someone in to straighten up your system.

At this point, most of us would say to factory reset everything and start over from scratch. But if you don't have a handle on your network or the basics of the NVR, that could be problematic as well.

As you are finding out, these better systems are not plug-n-play. If you want simplicity, but at the cost of not as good performance with things like motion blur at night, then it is best to go with a consumer based system like Ring, Arlo, Nest, Blink, Wyze that are simply hang them up and scan a QR code and be done. But like I said, the cameras are not as good, so night time performance usually struggles.

Thanks Wittaj - you are a star.I spoke to the installer ages ago re the network, and he did nothing about it, even though he spoke tohis advice line who advised that the nvr should be directly connected to the router, as did Dahua support before they stopped talking/emailing me.
It's reassuring to know that I haven't wrecked that camera.
As for the PoE ports, the three cameras on the house are connected directly to the PoE sockets. The two in the garage come via a single cable from the wireless receiver, into a device plugged into the main electricity supply, and a lead comes out of that into another PoE port on the nvr.
The installer eventually replied by email saying he would send one of his men to sort it out next week.
Meanwhile I am taking advice from the local consumer advice bureau.
I did have a look at the section dealing with camera passwords, and they all seem to have the same number of dots where the password lives as the main password I put in. From past experience with this sort of thing I wouldn.t know if this is significant. Either way, I have not interfered!!
Thanks for all your time and trouble. I'll wait and see what happens when or if this guy comes to "sort" it out.
Regards

QuattroZ, you are on your way.

Get your existing system working, then come back and read posts here for a few months. Then when you think you know a bit, buy a good camera, a computer to run blue iris, and a poe network switch, and start experimenting while you keep your existing system. Eventually you’ll get to the point where you can swap out the kit with the one you built and understand inside and out.
