Depot Manager, Evidence Manager, and multiple devices are connected over a network. At the time of deployment, your network administrator should have configured a network for Depot Manager, Evidence Manager, and the devices to communicate on. By default, Evidence Manager uses the Multicast messaging protocol with 18.104.22.168 as the IP address.
If need be, you can choose another messaging protocol:
- Unicast: Typically used when multiple networks are used with a router between the devices and the server. A unicast system involves one sender and one receiver, each with its own IP/network address. It is a one-to-one transmission from one point in the network to another point.
- Multicast: Can only be used on flat networks where the server and devices share the same subnet, with no routers in between. Multicast is group communication where data transmission is simultaneously addressed to a group of destination computers. Multicast can be one-to-many or many-to-many distribution.
- Broadcast: Broadcasting is the simultaneous transmission of a data packet to multiple network devices. Each network device receives all the signals sent by the transmitters. Security issues may arise during broadcasting and lead to data loss if a network is attacked by intruders. Used for smaller networks that do not support multicast or unicast.
For example, if you select the Multicast protocol:
- Multiple instances of Evidence Manager appear under Workstations.
- Multiple devices that are discoverable appear under Unknown Devices.
