The message “Network Abnormal” shows up when you’re trying to access your Hikvision NVR (or DVR or even a single camera) from your web browser or on the iVMS-4500 app. There are various reasons why this message pops up on your device.
In this article, we will provide a few how-to-fix tips that can help you resolve this problem and bring your security system back online.
How to fix Hikvision Network Abnormal issue?
Make sure the IP address (or DDNS) you’re typing is the right one and hasn’t changed. If the IP address of your NVR/DVR/IP camera has changed but you’re still hitting the old one, you’re still gonna see the web interface on your browser and that happens because the web browser is using cookies and has cached your previous IP address (which used to work).
In this case, you need to make sure that the IP address is correct. You can also delete the cache from your web browser and try it again.
If you don’t know how to clean the cache, just google your browser followed by “clear cache. For example “Mozilla Firefox clear cache”.
Restart the browser
Restart your web browser or your app. Sometimes the apps or browsers use the old settings and you need to restart them. Additionally, you may restart the phone and the computer as well.
Turn off and on your WiFi (or internet connection) from your device (computer or phone). Ensure that your internet connection indeed works. Open up some random websites to check if they open up.
Make sure you haven’t turned on the IP address restriction in the camera settings (or NVR/DVR settings). You should be able to find this option under the Network Settings of your device.
If that’s the case, you can get the web interface from another machine but would get an error message of “Network Abnormal” every time you try to log in.
A problem with the plug-in may also cause the Hikvision “Network Abnormal” message. This happens quite often especially when you try to access the device via the web browser.

In rare cases, you may have a problem with the network cable. Make sure it’s plugged properly and it’s crimped correctly.
If the cabling is exposed to the elements, check out if the line is okay. Sometimes even the rodents can chew the wires.
Make sure the ports are open and the port forwarding is done correctly. The ports need to open up on the router, you can access the router to check the settings. If using the P2P platform for remote viewing, make sure it’s enabled on the settings.
Update the firmware
Lastly, you may need to update the firmware of your IP camera, DVR, and NVR. Always keep your devices updated to the latest version. Contact the seller or manufacturer to get the latest release.
Be careful not to flash the wrong one. Additionally, you may contact the seller/dealer or installer for technical support.
