Follow these steps to remove a device from your Hik-Connect account:
Launch the Hik-Connect app on your mobile device.
Make sure you’re logged in with the same account that added the device.
From the Home screen, you’ll see all DVRs, NVRs, or cameras currently linked to your account.
Swipe left on the device you want to delete.
You’ll see a gear icon ⚙️ appear on the right.
Tap the gear icon to open the device settings.
Scroll all the way down in the settings menu.
Tap Delete Device.
A message will pop up asking if you’re sure you want to delete the device.
Tap Yes (or Confirm) to complete the process.
The DVR/NVR will now be removed from your Hik-Connect account.
If you need to re-add it later, simply scan the QR code on the recorder again.
If you’re sharing the device with others, deleting it will also stop their access.
If the device is bound to your account, it must be unbound before someone else can add it on their account.
For some older DVRs/NVRs, you may need to log in using a browser or iVMS-4200 to unbind the device if it doesn’t release from the app.
