Making reservations on your DHCP server
If your cameras get their network settings from a third-party DHCP server, then reserve the range of IP addresses that the cameras will use so that other devices cannot take them. Bind each IP address to a specific camera's MAC address. For details, see the documentation for your DHCP server.
DHCP IP address reservations have important benefits:
- Avoiding IP address changes, which disrupts live video streams, recordings, and FortiRecorder connections with the camera until you update Address to match the new IP address
- Preventing that IP address from being re-assigned to another device when the current DHCP lease expires
- Mimic a static IP address, yet still provide the benefit that IP addresses are still centrally managed on your DHCP server
FortiRecorder attempts to keep track of any DHCP-related IP address changes automatically by periodically sending DNS probes. However this requires that the camera is on the same subnet as FortiRecorder. If cameras are on remote networks, then this does not work; DHCP reservations are required.

Reserved leases cannot prevent misconfigured computers from using the same IP address, causing an IP address conflict, and breaking the connection of FortiRecorder with the camera. See Resolving IP address conflicts. |
