configuring the cameras with a static IP address, yet will provide the advantage that IP
addresses remain centrally managed.
•
Switch the camera to a static IP
— Use the FortiRecorder NVR to configure the camera
with a static IP address. This removes the requirement of your cameras to remain within
reach of the DHCP server, which provides 2 advantages:
• You can disable DHCP if not otherwise required (recommended for better security).
• You can move the cameras to a remote location on your network that would not ordinarily
be reachable by your DHCP server.
Connecting FortiRecorder to the cameras
After you configure the DHCP server (you do not have to if you already have one), you can
connect and configure the cameras.
Once you connect the cameras to the NVR, the NVR can automatically discover the cameras.
Then you can configure the discovered cameras.
Requirements
• On your computer, the Apple QuickTime 7.1 or greater plug-in installed for your web
browsers
• At the camera’s location on the network, power over Ethernet (PoE)
This could be provided by a FortiSwitch-80-PoE or perhaps your ISP’s cable modem.
If you continue to let your cameras use DHCP, you
should
configure
on a third-party DHCP server, the equivalent setting). Failure to do this may appear to work
initially, but eventually could periodically, temporarily interrupt connectivity with the NVR,
resulting in lost video.
This can happen if either the DHCP pool is too small for the number of cameras, or if a
misconfigured computer accidentally takes a camera’s DHCP lease: the DHCP server will
ultimately be forced to assign the camera’s IP address to a different client. If this happens,
when the camera next requests a lease, it will receive a new, different IP address, and the NVR
will
not
be notified.
Connectivity interruptions are usually self-correcting: within a few minutes, the
FortiRecorder NVR should detect the camera’s IP address change. To restore connectivity
manually, either manually update the camera’s definition on the NVR to reflect the new IP, or
discover the camera again.
