LNVR Not responding to PTZ Presets triggered by Global I/O or Scheduler


When setting up a global I/O to set a PTZ Preset, the PTZ Preset does not work. However, using the preset manually works as expected.


When LNVR security is on (access is restricted to Windows accounts that are members of the LNVUsers group), there are two ways to confirm that the correct Windows account is used when OnGuard communicates with LNVR:

  1. Specify a Windows account that is part of LNVUsers group on the recorder’s tab in System Administration. When this is done, all OnGuard applications and services will use this account regardless of what account is in use.
  2. Make sure that the account under which OnGuard applications and services are running is part of the LNVUsers group.

For option 2, if the LNVUser Group is required (rather than Anonymous DCOM), then the Linkage Server must also run on the OnGuard server using a user from that LNVUser Group.

To verify this, go into Windows Services:

  1. Right-click LS Linkage Server.
  2. Select Properties.
  3. Select the Logon tab.
  4. Confirm that the user is a high-level (admin) user in the LNVUSer group.

If it is not, make this change and then restart the Linkage Server.
