If you still have access to your camera via your web browser, you can use the Web interface to reset your camera.
The camera will not be able to dial into your Wi-Fi network anymore as it lacks the WiFi key. Also, you will probably no longer have the old IP address, but automatically obtain a new one from your router as soon as you connect the camera via LAN cable. After that a new first installation is necessary. Details can be found here: Installation Wizard.
To perform the reset, please hold the reset for at least 15 seconds (rather too long than too short) while the camera is being powered by the AC adapter and the LAN cable has been removed. If the reset is incomplete, it may be that the camera is subsequently no longer accessible. In this case, perform the reset again, and then disconnect the power of the camera overnight. If the reset is successful, the camera will reboot (PTZ cameras will recognize it as performing a calibration run) and will return to factory default.
If you no longer have access to the web interface and the reset button is damaged, you still have the reset on the SD card of your camera. Create a file for that and give it the name reset (very important without file extension!) - on Windows this is not that easy, so we have the necessary file here for download. The file is packed and must first be freed from the zip container before we can use it.
reset : Remove the SD card from your camera and connect the card to your computer via a card reader. Then place the file in the root directory (ie directly on the card, not in a subfolder) of the memory card and then eject the SD card. To get the camera back to factory settings, please insert the SD card back into the card slot of the camera and then restart the camera.
wps : To reconnect the camera to your Wi-Fi network after rebooting, you can create a file called wps (very important without file extension!) - it's not that easy on Windows, so we have the necessary file here for download provided. The file is packed and must first be freed from the zip container before we can use it. Place this file in the root directory (ie directly on the card, not in a subfolder) of the memory card and then insert it back into the card slot of your camera. Then start the WPS mode of your WLAN router and restart the camera. After restarting, the camera will be in WPS mode and will try to connect to your router.
