Modem Power Control
The Modem Power Control setting controls the yellow Power I/O
signal line of the CCFC camera.
The yellow wire, or switch output, is intended to manage the
power to a communication device such as a cell modem. This is
useful in a solar powered site when there is a need to limit power
consumption of communication devices.
This option enables the CCFC to supply up to a maximum of 750
mA of current. The voltage level will be the same as the camera’s
input power (i.e. 12 Vdc).
Some modems require a warm up time or a period of time to
register on a network. The
Early Power On option is there for this
purpose. Enter a value in seconds; the maximum value that can be
entered is 300. The default is 120 seconds.
Figure 12-43 Modem Power Control
In order to communicate via cell modem, set the CCFC’s wired
Ethernet settings to the appropriate values as per the cell
modem’s manual. The required values are IP Address, Netmask,
Default Gateway and Primary Nameserver. If the cell modem has
a firewall enabled, set up port forwarding to the camera. For
accessing the camera’s webpage, forward the HTTP port (default
80). To access the camera’s FTP server through the cell modem,
forward the camera’s FTP server port (21) and the port range
1024-1043.
