The default password of camera is admin.
If you forgot the new password created by yourself or default password admin can't work, please reset camera so that password comes back to default one admin.
Please use a small pin to press and hold the small button (reset button) at the bottom of camera for about 30 seconds until you hear a click sound when camera is plugged into power source. Then wait for 20 seconds until camera rotates, it indicates camera resets successfully and password comes back to default one admin. (Model I21E/PD1 won't spin even if reset succeeds)
