As cameras join the network, they should appear in the list of DHCP clients on Monitor >
DHCP Status > DHCP.

Setting the system time
For many features to work, including camera synchronization, scheduling, logging, and
SSL/TLS-dependent features, the FortiRecorder system time must be accurate.
You can either manually set the FortiRecorder system time or configure the FortiRecorder
appliance to automatically keep its system time correct by synchronizing with a Network Time
Protocol (NTP) server.
Later, when cameras are added to your surveillance system, your FortiRecorder NVR will
synchronize the camera clocks with its own to keep them in agreement.
To configure the system time
1. Go to System > Configuration > Time.
2. Either manually set the date and time or select to synchronize with NTP server.
3. Click Apply.
If you manually configured the time, or if you enabled NTP and the NTP query for the current
time succeeds, the new clock time should appear in System time. (If the query reply is slow,
DHCP Excluded
Range
To configure IPs that should be omitted from the DHCP pool and
never given to DHCP clients (such if there are printers with manually
assigned static IP addresses in the middle of your DHCP range),
click New.
Reserved IP
Address
To bind specific MAC addresses to a specific DHCP lease,
guaranteeing that the DHCP server will never assign it to another
DHCP client, click New.
Caution: Reserved leases cannot prevent misconfigured computers
from taking the IP address, causing an IP address conflict, and
breaking the FortiRecorder NVR’s connection with the camera. See
“Resolving IP address conflicts”.
Tip: To mimic a static IP address for your cameras, yet still provide
the benefit that IP addresses are still centrally managed and
configured on your DHCP server, configure reserved IP addresses.
Setting name Description
NTP is recommended to achieve better time accuracy. NTP requires that your FortiRecorder be
able to connect to the Internet on UDP port 123. Adjust your firewall, if any, to allow these
connections.
