Cable connection
Shut down the peripheral devices prior to connection. Connect the supplied cables from Network Camera
to the related devices according to following steps. Note that power adaptor must be kept unplugged until
other cables are firmly connected. For the first access to Network Camera without Ethernet,
administrators may use the included null modem cable to connect to COM for direct connection. It is also
convenient for administrators to access Network Camera through the null modem cable directly without
modem or Ethernet card. After necessary information is entered, a modem can be used to dial into the
Internet.
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.
