Chapter 7: Services Tab
The Services tab covers the configuration of system
management services including Ping Watchdog, SNMP
Agent, Web Server, SSH Server, Telnet Server, NTP Client,
Dynamic DNS, and System Log.
Ping Watchdog
Ping Watchdog sets the airCam Dome to continuously
ping a user defined IP address (it can be the Internet
gateway for example). If it is unable to ping under the user
defined constraints, the airCam Dome will automatically
reboot. This option creates a kind of “fail-proof”
mechanism.
Ping Watchdog is dedicated for continuous monitoring
of the particular connection to remote host using the
Ping tool. The Ping works by sending ICMP “echo request”
packets to the target host and listening for ICMP “echo
response” replies. If the defined number of replies is not
received, the tool reboots the airCam Dome.
Enable Ping Watchdog Enables the Ping Watchdog tool.
• IP Address To Ping Specify the IP address of the target
host which to be monitored by the Ping Watchdog tool.
• Ping Interval Specify time interval (in seconds)
between the ICMP “echo requests” are sent by the Ping
Watchdog Tool. The default value is 300 seconds.
• Startup Delay Specify initial time delay (in seconds)
until the first ICMP echo requests are sent by the Ping
Watchdog tool. The default value is 300 seconds.
The value of Startup Delay should be at least 60 seconds
as the network interface and wireless connection
initialization takes a considerable amount of time if the
airCam Dome is rebooted.
• Failure Count to Reboot Specify the number of ICMP
echo response replies. If the specified number of ICMP
echo response packets is not received continuously, the
Ping Watchdog tool will reboot the airCam Dome. The
default value is 3.
