MERCUSY camera is showing offline after changing or resetting the router.

*Note: All MERCUSYS cameras require and only work with the MERCUSYS App.

If you can't get smart cameras online to the network after changed the ISP / router, or the router is reset, you may try the following guides:

Currently, there is no setting on MERCUSYS APP allowing us to switch to a different wireless network directly, but you can achieve this goal using the following two methods instead:

Method 1. Apply the same wireless settings (including the wireless network name, wireless encryption, and password) on your new router as on the old one. Then the camera should be able to connect to the new router automatically.

Method 2. If you can’t change the wireless settings, you can also reset and reconfigure the smart camera again with the new Wi-Fi.

Please refer to the QIG to reset your smart camera. (Both soft reset and hard reset are OK.)

For reconfiguration, here are some articles for your reference.
