unplugged until other cables are firmly connected. In the environment without Ethernet,
administrators can use the included null modem cable to connect to Network Camera
directly and access point-to-point. After necessary information is entered and saved,
turn off Network Camera and remove the null modem cable. Follow the installation of
modem mode in next paragraph to connect to Internet. Note Network Camera will not
really reset system where it is used to in null modem mode.
Modem mode
If users have setup a remote dialup server or subscribed to an ISP service, Network
Camera can be configured to dial to the server upon user-defined events. Otherwise it
will wait permanently for the user’s call to establish a network connection to provide
services. Before installation, make sure the necessary dialing information is correctly
setup via Ethernet or null modem connection.
Power on
Make sure all cables are correctly and firmly connected. Turn on cameras, sensors, alarm
devices, and then finally attach power adaptor of Network Camera to the electric power
outlet*. Since most automatic detections of hardware perform when the system starts,
Network Camera should be turned on after all peripherals are turned on and ready.
Connect the power jack of the power adapter to Network Camera prior to plugging the
utility end into a utility power outlet. It will reduce accidental electric surge shock.
