1. On your computer, open the IP Search Tool. Checked if the tool can still find the device.

If the tool can still find the IP address of the device, proceed with updating the firmware.

2.  If the IP Search Tool cannot find the IP address of the device, but you still remember the IP address of the device, try to ping the specific IP address. If IP address can still be pinged, proceed with updating the firmware.

3. If the device cannot be detected by the IP Search Tool and you don’t remember the IP address of the device, please try to ping the temporary IP address as listed below. 

   · IP Camera – 192.168.0.120

   · NVR – 192.168.0.121

4. If the IP address can still be pinged, proceed with updating the firmware.

Notes:

1. Please ensure that the computer has the same IP range as the IP addresses listed above. For example, before you ping 192.168.0.120, set the computer’s IP address to 192.168.0.x. 

2. It is highly recommended to connect the device directly to the computer to avoid any IP conflict.

3. After pinging timeout and the device can be pinged again, immediately click ‘Add’ and then ‘Update’ on the Update Tool. Please ensure to uncheck ‘add online device’.
