Vivotek IP3111/IP3121 user manual Restore button, Power adapter, Auto Iris Lens Connector

Restore button

There is a button hidden in the box for restoring the system factory default settings. When the system fails to install or operates abnormally, use the included assistant stick in the package and follow the following procedures to reset the system back to its original status.

Poke the assistant stick into the hole to press down on the restore button. Restart the system by unplugging and re-plugging the power jack. While keeping the button pressed, the system will perform POST twice rather than the usual once, which can be observed from the flashing LEDs. After the system flashes the LEDs for the second time, withdraw the stick to release the button. The system will have restored factory default settings at that moment.

Power adapter

Connect the power jack of the included power adapter. Connecting the power adapter should be the last operation while physically installing NetworKam.

Auto Iris Lens Connector
