Background:
When a NetGuard or NetGuard-EVSconnects to a surveillance
system, an amount of initial data communication, including the
exchange of contact IP addresses goes on in the background,
completely automatically and transparent to users.
However, when a NetGuardorNetGuard-EVSon a local network
connects to a surveillance system which is also on the local network,
the Image Server may, if different subnets are involved, not
recognize the NetGuard's or NetGuard-EVS's IP address as being
local.
When this is the case, the Image Server may not return a suitable IP
address to the NetGuard or NetGuard-EVS for further
communication between the two.
Therefore, you are able to define a list of IP ranges which the Image
Server should recognize as coming from a local network, in which
case it will respond with a suitable IP address and seamless
communication will be possible.
Max.
number of
clients
You are able to limit the number of access clients allowed to connect
at the same time. Depending on your NetDVMS configuration and
the performance of the hardware and network used, limiting the
number of simultaneously connected clients may help reduce server
load.
If more than the allowed number of simultaneously connected
access clients attempt to log in, only the allowed number of access
clients will be allowed access. Any access clients in excess of the
allowed number will receive an error message when attempting to
log in. By default, a maximum of ten simultaneously connected
access clients are allowed.
To specify a different maximum number of access clients allowed to
connect at the same time, overwrite the value in the Max. number of
clients field with the required value.
Tip: To allow an unlimited number of simultaneously connected
access clients, type 0 (zero) in the Max. number of clients field.
Note: A four-minute session timeout period applies for access client
sessions on the Image Server. In many cases, access client users
may not notice this at all. However, the session timeout period will
be very evident in some cases, for example if you set the Max.
number of clients value to 1: When this is the case, and the single
allowed access client user logs out, four minutes must pass before it
will be possible to log in again.
