If no joy, I'd consider resetting the cam to factory defaults and try setup again.
From Page 54 of the Axis p3364 User Manual:
"How to reset to factory default settings
Important: Reset to factory default should be used with caution. A reset to factory default resets all settings, including the IP address, to the factory default values.
To reset the product to the factory default settings:
1. Disconnect power from the product.
2. Press and hold the control button and reconnect power.
3. Keep the control button pressed for 15–30 seconds until the status LED indicator flashes amber.
4. Release the control button. The process is complete when the status LED indicator turns green. The product has been reset to the factory default settings. If no DHCP server is available on the network, the default IP address is 192.168.0.90
