Title: DS-7716NI-SP Cannot Add New DS-2CD1043G2-LIU Cameras – "IP Camera Does Not Exist" / "Unknown Error" – Possible Compatibility or NVR Issue?

[dennis_mutuku]

Hello everyone,


I'm looking for some advice regarding a Hikvision system that I'm currently troubleshooting. I've spent a considerable amount of time investigating the issue and would appreciate any insights from those familiar with older Hikvision NVRs and newer IP cameras.

System Overview​

NVR​

• Model: DS-7716NI-SP
• Firmware: V3.4.5 build 171229

PoE Switch​

• Model: DS-3E1510P-EI/M
• Firmware: V3.0.13 build 241120

New Cameras​

• 2 × DS-2CD1043G2-LIU
• Firmware: V5.8.10 build 250714

---

Existing Installation​

The NVR has been in service for several years and currently manages multiple Hikvision IP cameras.


Several cameras are online and working correctly through the NVR, including cameras with addresses such as:

• 192.168.254.18
• 192.168.254.28
• 192.168.254.6
• 192.168.254.8
• 192.168.254.23

These cameras display live video normally.

Problem Description​

We recently purchased two new Hikvision DS-2CD1043G2-LIU cameras.


The cameras were:

• Successfully activated using SADP
• Assigned unique IP addresses
• Connected through the Hikvision DS-3E1510P-EI/M PoE switch

Assigned addresses:


Camera 1

• IP: 192.168.254.30
• MAC: 04-EE-CD-4A-8D-34

Camera 2

• IP: 192.168.254.31
• MAC: 04-EE-CD-4A-8D-A1

Subnet Mask:

• 255.255.255.0

Gateway:

• 192.168.254.1

---

What I've Verified​

SADP Detection​

Both cameras are visible in SADP and show as:

• Activated
• Correct model numbers
• Correct firmware versions
• Unique IP addresses

ARP Verification​

From my laptop, I can see both cameras in the ARP table:



192.168.254.30 -> 04-ee-cd-4a-8d-34
192.168.254.31 -> 04-ee-cd-4a-8d-a1


This suggests:

• The cameras are powered
• The switch is forwarding traffic
• The cameras are physically connected
• There are no duplicate IP addresses

Switch Status​

The DS-3E1510P-EI/M correctly detects the connected devices and shows active links on the relevant ports.

---

NVR Behaviour​

When attempting to add the new cameras to the NVR:

• Protocol: HIKVISION
• Management Port: 8000
• Username: admin
• Correct camera password entered

The NVR reports one of the following:




Offline (IP camera does not exist)


or




Unknown Error


The cameras never come online.

---

Additional Observation​

While troubleshooting, I discovered that this issue may not be limited to the new cameras.


Several existing channels are also showing:




Offline (IP camera does not exist)


Examples include:

• D06
• D09
• D11
• D13
• D15

These cameras were reportedly connected and operational at some point in the past, although I cannot verify exactly when they stopped working.


At the same time, several other cameras remain online and fully functional.


This has made me wonder whether the problem is broader than just the newly purchased cameras.

---

Camera Management Example​

Current status resembles:




D03 Online
D04 Online
D05 Online
D07 Online
D08 Online
D10 Online
D12 Online
D14 Online
D16 Online

D06 Offline (IP camera does not exist)
D09 Offline (IP camera does not exist)
D11 Offline (IP camera does not exist)
D13 Offline (IP camera does not exist)
D15 Offline (IP camera does not exist)


The new cameras were added to available channels but remain offline with either:




IP camera does not exist


or




Unknown Error

---

Firmware Concern​

One thing that stands out is the age difference between the NVR and the new cameras.

NVR​

DS-7716NI-SP
Firmware V3.4.5 build 171229

New Cameras​

DS-2CD1043G2-LIU
Firmware V5.8.10 build 250714


There is roughly an 8-year gap between the firmware generations.


I am wondering whether the NVR firmware may be too old to properly support these newer G2 cameras.

---

Network Configuration​

NVR LAN1​

IP Address: 172.23.5.234
Subnet Mask: 255.255.254.0
Gateway: 172.23.4.10

Camera Network​

192.168.254.x


The NVR already communicates successfully with several cameras on the same 192.168.254.x range.

---

Questions​

1. Is the DS-7716NI-SP officially compatible with DS-2CD1043G2-LIU cameras?
2. Has anyone successfully connected G2-LIU series cameras to this older NVR model?
3. Is there a recommended firmware upgrade path for the DS-7716NI-SP?
4. Could the issue be related to camera authentication, security settings, or protocol compatibility?
5. Given that several older channels are also showing "IP camera does not exist", could this indicate a broader NVR camera-management or internal network issue rather than a problem with the new cameras themselves?
6. Are there any known limitations on the DS-7716NI-SP regarding newer Hikvision firmware generations?

Any advice or suggestions would be greatly appreciated. I've verified cabling, activation, IP addressing, switch operation, and camera visibility in SADP, but I'm now unsure whether I'm dealing with a compatibility issue, an NVR firmware limitation, or a wider NVR configuration problem.


Thank you in advance for your help.

Batch configuration tool, add cameras there, System Config->Password protect -> Close

You need to lower new security on cameras so your old NVR can actually authenticate on cam.

Cheers,

Windows PC or Laptop:

Download this software:

https://www.hikvision.com/europe/support/tools/hitools/cl9283ea91cbe218de/

After installation run it, you will see device on network.
Select cameras and add them by providing admin password
Once you add select camera and press System Config -> Password protect -> Close

After that try to add camera to your NVR again.

On adding i get this error message: failed to connect to the device, please note that the cameras are connected to a switch which is now connected to the nvr

 

[trempa92]

Since you stated that NVR already communicates with other cammeras succesfully on 254.X it means those cameras are most likely connected to NIC2 on NVR which has its own defined subnet.

Make sure the cameras that dont work are not networked in NIC1, which is totally different subnet. Should remain on NIC2.

 

[dennis_mutuku]

Wow it has finally worked but am wondering whether since the NVR Has 16 channel can oi connect more than 16 cameras or ill be resricted to 16 cameras only

 

[trempa92]

Thats it, you've hit the ceiling

 

[dennis_mutuku]

You have been very helpfull in this, I was almost advising and advocating for purchase of a new Modern Nvr

 

[trempa92]

If only Live and Playback(motion) was requirement, there was no need for a new NVR.
