If a SharpV unit is configured in DHCP mode but no DHCP server is accessible on the network, the unit switches to a fixed static IP address known as the fallback IP. If the network does not have DHCP, for example, if you are connecting a SharpV camera directly to a laptop for testing or configuration purposes, you can connect to the camera by using the fallback IP address.
What you should know
IMPORTANT: You should not use the fallback IP for an installation in the field.
You might need to use the fallback IP if you are connecting a SharpV camera directly to a laptop for testing or
configuration purposes.
- This situation should be prevented because devices require an accessible DHCP server to communicate properly when configured in DHCP mode.
- If this happens, the device will not be accessible using the last known, or last leased IP addresses.
- If two devices on the same network use the fallback IP, it cause traffic collisions, leading to communication issues.
- When the DHCP server is accessible, rebooting the device by physically pulling the power cable will force it to contact the DHCP server to get a new IP lease.
Procedure
- If there is more than one Sharp camera on the network, isolate the camera by connecting it directly to a computer with the use of a PoE++ injector.
-
Connect to the camera using the fallback IP address
(
192.168.10.100). - Reconfigure the camera as required and reconnect to the network.
