The “No more IP camera allowed” error shows up when you try to connect an IP camera via a PoE switch to a Hikvivion PoE NVR (with a built-in PoE switch).
If you connect the IP camera straight to the built-in PoE switch at the back of the Hikvision NVR, the NVR detects the camera and populates the IP address on the system. The camera shows up fine on the screen.
However, in some cases, if you connect the same IP camera to an external PoE switch and then you try to add the camera on the Hikvision NVR via the local interface, you may get the error message “no more IP camera allowed”. There are a few reasons why this issue happens. Read this guide to fix the error quickly.
How to fix the “No more IP camera allowed” on a Hikvision NVR
The issue is related to the Plug and Play function of the Hikvision NVR, when you connect the IP camera straight to the PoE NVR the plug and play function works and is able to properly add the camera on the NVR.
But this feature is not supported if you try to add the same camera connected to an external PoE switch. The plug and play function doesn’t add the camera automatically.
You need to change the channel from Plug and Play (auto) to Manual and after that add the camera’s IP address manually.
First of all, run the SADP tool on your laptop and find out the IP address of the camera, assign a static IP address to the camera matching your local network (where the external PoE switch is located). Make sure to set the right gateway and subnet mask.
Then you have to go to the Camera Management section and click Custom Adding. There you can manually type the static IP address of the camera, the username, and the password of the camera. Click Add and the camera will show up, no longer saying “no more IP cameras allowed”.
A few other things to keep in mind that sometimes are related to this issue:
Make sure the NVR is updated to the latest firmware. Ensure that the IP camera is compatible with NVR. The resolution has to be supported by the machine.
Also this “no camera allowed” Hikvision error message may show up if the total bitrate of the IP cameras exceeds the limit designed by the manufacturer.
For example, if you have a 16 channel Hikvision NVR and you’ve added 10 cameras with 10 Mbps bitrate for each camera and when you add the 11th camera the NVR won’t add it, because the NVR is struggling to handle the current bitrate.
Go to Configuration > Video & Audio and make sure the max Bitrate is set up properly. The total bitrate of all the IP cameras has to be less than the incoming bandwidth specified by the manufacturer.
Note: if you get an error that says “No IP camera for deletion”, check out these instructions.
