LYNC ROOM SYSTEM (LRS)


• Familiar • Native Lync • Windows Embedded

7 Standard


• Joining the LRS to a domain is optional• Requires manual import of certificates (for example, trusted root).

• Joining to a domain has benefits• Easy certificate import.• Easy management by assigning Active Directory groups and

domain users administrative rights.

• When joining LRS to a domain, pay attention to• GPOs (Group Policy objects) assigned to the OU (organizational unit) - create a separate

OU if possible.• Block Inheritance and No Override can cause unwanted effects - check!• Also settings for auto lockout, power management, additional authentication, access to

local drives, auto start of applications, and so on.


LRS and bandwidth• Fullscreen video, 1080p

• 1920x1080 (16:9)• Typical 3200 kbps

• Bigger multiview• Conferencing is the norm
