Milestone just released XProtect version 2019 R3 with some great new features:
- Metadata Search in SmartClient
- Driver Framework
- Adaptive Streaming
- and more…
However, there are three Milestone KBs that you should consider before jumping in.
Smart Clients older than 2019R3 are not compatible
KB 19309 discusses the details of the upgraded security protocols used in XProtect 2019 R3 and that this new version of XProtect will not be backwards compatible with older version of Smart Client.
With the release of XProtect 2019 R3, stronger security features were implemented, which means the Service Channel feature has been removed. As this feature was used in the earlier versions of XProtect, the older versions of the Smart Client will no longer be able to connect to an XProtect 2019 R3 server.
The solution: Upgrade all your Smart Client users to 2019 R3. The smart client itself IS backwards compatible with older versions of Milestone XProtect.
There are specific NVIDIA driver requirements
KB 17957 outlines performance issues and security flaws in the previous version of NVIDIA drivers when using hardware acceleration. It also states that the minimum driver version of 418.96 onwards is required for XProtect 2019 R3.
When using Nvidia hardware acceleration for the XProtect Recording Server, Mobile Server and Smart Client, you may experience issues like (but not limited to) image quality degradation, lower performance than expected, memory leaks or even crashes in some cases.
The solution: Upgrade NVIDIA drivers to v. 418.96 onwards.
Installing mobile server might lock your user account
KB19308 discusses how the new version of mobile server may lock your user account due to how it passes the credentials to the data collector service.
If you install the XProtect® Mobile Server 2019 R3 under a domain\Windows account, the account may be locked (if there is a policy for locking the account after several unsuccessful attempts).
The solution: Install the recording server initially as a network service account and then change the service to run as the windows service account.
Recording Server crashing, Intel GPU 3rd/4th generation & Windows 10
KB19488 outlines the issue found with hardware accelerated video motion detection when upgrading a recording server to 2019 R3 .
After upgrading one of the XProtect VMS products (Corporate, Expert, Professional+, Express+, Essential+) to version 2019 R3, the Recording Server fails when software motion detection is enabled and it is utilizing the Intel GPU on Intel 3rd and 4th generation chipsets running on Windows 10.
The solution: Make sure that the machine that is in use also has an Nvidia GPU available, or you may need to install an additional Nvidia video card. Once this is done, disable the integrated Intel GPU so that only the Nvidia one is in use.
Inputs do not work in XProtect VMS 2019 R3
KB19672 outlines default security settings in Milestone 2019 R3 VMS that will cause some inputs, typically using the legacy driver, not to function as expected.
With the design and security changes introduced in XProtect® VMS products 2019 R3 (Corporate, Expert, Professional+, Express+, and Essential+), the inputs may not work by default on some devices. Not all devices are affected by this issue and most of the affected devices are working through Legacy Device Pack drivers.
The solution: Enable the alert server. See KB for full instructions.
