Video device drivers
About video device drivers
Your system uses video device drivers to control and communicate with the camera devices
connected to a recording server. You must install video device drivers on each recording server on
your system.
When you install your system, video device drivers are part of the initial installation process. Milestone
releases new versions of video device drivers, known as XProtect Device Pack, from time to time and
make them available for free on the Milestone website. When you update video device drivers, you
can install the latest version on top of any version you may have installed. Stop the Recording Server
before you install, otherwise you need to restart the computer.
To ensure best performance, always use the latest version of video device drivers.
About removing video device drivers
If you no longer require video device drivers on your computer, you can delete the device packs from
your system. To do so, follow the standard Windows procedure for removing programs.
If you remove video device drivers, the recording server and the camera devices cannot communicate
any longer. Do not remove device packs when you upgrade because you can install a new version on
top of an old one. Only if you uninstall the entire system, you may remove the device pack.
Services
About the Management Server service and Recording Server
service
You can check the state of the Management Server service or the Recording Server service by looking
at the icon in the notification area of the computer running the management server or recording server.
In the notification area, you can start and stop the Management Server service/Recording Server
service, view status messages, check version information and more. To do this, right-click the server
service icon. Depending on server type, select the needed icon. If you use multiple instances of the
Recording Server service, you select a particular instance or all instances from a sub-menu.
If you stop the recording server service at some point, your system cannot interact with devices
connected to the recording server. This means you cannot view live video or record video. If you stop
the management server service, you cannot use the Management Client at all.
Important: When the Recording Server service is running, it is very important that Windows Explorer
or other programs do not access Media Database files or folders associated with your system setup. If
they do, the recording server might not be able to rename or move relevant media files, which might
bring the recording server to a halt. If this situation has already occurred, stop the Recording Server
service, close the program accessing the relevant media file(s) or folder(s)n, and restart the Recording
Server service.
