		If you receive: Reply from <IP address>: bytes = 32; time = 10 ms..... - this means that
		the IP address may already be in use by another device on your network. You must obtain
		a new IP address and reinstall the unit.
		If you see: Request timed out - this means that the IP address is available for use with
		your camera. In this case, check all cabling and reinstall the unit.

		commands.
		2) Access the unit and disable DHCP in the TCP/IP settings. Return the unit to the main
		network. The unit now has a fixed IP address that will not change.
		3) As an alternative to 2), if dynamic IP address via DHCP or BOOTP is required, select the

		but will notify you if the address changes.
	Proxy server.	If using a proxy server, try disabling the proxy setting in your browser.
	Other networking problems.	Test the network cable and connectors by connecting it to another network device, then
		Ping that device from your workstation. See the instructions above.
	Incorrect protocol.	When HTTPS is enabled, ensure that the correct protocol (HTTP or HTTPS) is used when
		attempting to log in. You may need to manually type in http or https in the browser's
		address bar.
	Host name.	Check that the host name and DNS server settings are correct. See the basic and
		advanced TCP/IP settings.

		of a firewall/proxy server.
Your camera is accessible locally, but not externally
	Firewall protection.	Check the Internet firewall with your system administrator.
	Default routers required.	Check if you need to configure the default router settings.
Poor or intermittent network connection.
	Network switch.	If using a network switch, check that the port on that device uses the same setting for
		the network connection type (speed/duplex) as set in the advanced TCP/IP settings.
		The Auto-Negotiate setting is recommended.
MPEG-4 multicast is not displayed on the client
	Multicast not enabled.	Check the network RTP settings, see Network - RTP (multicast), on page 34.
	Connection method not enabled.	Check that the relevant MPEG-4 connection methods are enabled in the AMC control
		panel applet (network tab).
