Hi Kan,
Please try the tool attached to push the IP address of the camera. Please follow the instructions below.
Please rename the file to .exe extension and run the program.
1. Set laptop or PC to a static IP that will match with camera IP class and range that you are going to use.
2. Please make sure you have direct connection to the camera. You can connect the camera either thru POE injector or to the same POE switch.
3. Enter the MAC of that camera, hit enter.
4. Enter an unused IP to that camera, hit enter. Please make sure the new IP is in the same class and range as your PC or laptop.
5. Screen will now disappear.
6. Run AV100 and scan the camera again.
Please let me know if this still does not work.
