Could you provide us MIP SDK for XProtect Enterprise 8.1a ?

I don’t know whether MIP SDK for XProtect Enterprise 8.1a exists or not.

If it exists, please kindly provide us it.

Thank you and best regards,

Lee

The best MIP SDK for XProtect Enterprise 8.1a is the newest.

See - https://developer.milestonesys.com/s/article/about-MIP-SDK-compatibility-with-XProtect-product-versions

Note that Milestone does not maintain a list of old MIP SDKs, you would be doing yourself a disservice if using an old MIP SDK.
