Since it is asked over and over again, an update on the dual monitor issue:
From the client:
Running the Luxriot Client on a Dell PC with dual monitors. The desktop is extended across both monitors. When you drag the client application from monitor 1 to monitor 2 the camera images (16) disapear and every screen displays “Unspecified error”. The error flickers between a screen with an image of a camera and the error message at the bottom, and a black screen with diagonal white stripes and the error message in the middle.
This is a known issue caused by inability of DirectX subsystem to use secondary monitor properly. The workaround options are:
Make sure you are using latest drivers for video board
For the best performance we recommend you to switch on background services optimization in Windows performance options (see the attached screenshots) and to run LuxRiot DVR in service mode. This will give you upto 8% CPU performance increase.

Tests performed on Intel Pentium D 3.0 GHz Dual Core computer with Microsoft Windows XP Professional + SP2 and Microsoft Windows 2003 Server + SP1, no local client, 10 network cameras recording. LuxRiot Enterprise Edition 1.2.22 has been used for testing.
Under certain circumstances Arecont Vision network cameras may produce low frame rate (FPS).
Resolution
Typical low frame rate issues and workarounds for Arecont Vision network cameras are:
Arecont Vision network cameras are not designed for concurrent access. So frame rate will slow down dramatically if two or more users are watching video from the same camera at the same time. Beside this Arecont Vision Network Camera Search Wizard in LuxRiot DVR will not find the camera if this camera already transmits video to some user.
Arecont Vision megapixel camera consumes large traffic while operating, e.g. AV 3130 camera in max quality mode consumes approx. 20Mbps. Certain network equipment have been noticed to create image transmission problems or slow down frame rate. For example, 3Com routers are not recommended. To bypass network transmission problem try to disable “use double packets” (Advanced tab). This feature specifies whether to use data packets with 2KB instead of the regular 1KB for image transmission (by default, 2KB). This allows increasing image transmission bandwidth, but may lead to a less stable performance on overloaded networks.
This wizard will guide you through the process of archive integrity check and repair. It is strongly recommended to back up all archive data before running this wizard. Also it is suggested to run Scandisk first to insure drives and file system integrity.
Archive Backup Wizard will guide you through the process of creating archive backup on hard/network drives or CD/DVD discs. Standalone Archive Viewer will be written on removable disc to allow viewing archives without LuxRiot DVR being installed.
