Enable ARP/Ping setting of IP address - The IP address can be set using the ARP/Ping method, which associates the unit's MAC address with an IP address. Uncheck this option to disable the service in order to prevent unintentional resetting of the IP address. For more information see Other methods of setting the IP address in the AXIS 223M Installation Guide.
Notes: | • | The ARP/Ping service is automatically disabled two minutes after the unit is started, or |
| as soon as an IP address is set. | |
| • | Pinging the unit will still be possible when this service is disabled. |

IP address assignment via DHCP may lead to the situation where the IP address changes and you lose contact with the camera. Configure the options for notification of IP address change (under Services) to receive notification from the camera when the IP address changes.
