The legacy device pack can only be installed if the system has a regular device pack installed. The drivers from
the legacy device pack are automatically installed if a previous version is already installed on your system. It is
available for manual download and installation on the software download page
(https://www.milestonesys.com/downloads/).
Stop the Recording Server service before you install, otherwise you need to restart the computer.
To ensure best performance, always use the latest version of device drivers.
Requirements for offline installation
If you install the system on a server that is offline, you need the following:
l
The Milestone XProtect VMS Products 2023 R1 System Installer.exe file
l
The software license file (SLC) for your XProtect system
l
OS installation media including the required .NET version

Secure communication (explained)
Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP) for
secure communication over a computer network. In HTTPS, the communication protocol is encrypted using
Transport Layer Security (TLS), or its predecessor, Secure Sockets Layer (SSL).
In XProtect VMS, secure communication is obtained by using TLS/SSL with asymmetric encryption (RSA).
TLS/SSL uses a pair of keys—one private, one public—to authenticate, secure, and manage secure connections.
A certificate authority (CA) is anyone who can issue root certificates. This can be an internet service that issues
root certificates, or anyone who manually generates and distributes a certificate. A CA can issue certificates to
web services, that is to any software using https communication. This certificate contains two keys, a private
key and a public key. The public key is installed on the clients of a web service (service clients) by installing a
public certificate. The private key is used for signing server certificates that must be installed on the server.
Whenever a service client calls the web service, the web service sends the server certificate, including the
public key, to the client. The service client can validate the server certificate using the already installed public
CA certificate. The client and the server can now use the public and private server certificates to exchange a
secret key and thereby establish a secure TLS/SSL connection.
For manually distributed certificates, certificates must be installed before the client can make such a
verification.
See Transport Layer Security for more information about TLS.
