That's right. There's a slightly newer version for yours (4.61.030), but it may not receive further updates. It seems a strange decision not to update the I series top have that feature, as the cheaper original K series does have it. Here's the link to 4.61.030:
That's correct. Even the very latest version for your NVR does not support the Areas feature. As that NVR is 'End of life' Hikvision may never add any new features to it; they'll possibly only provide updates to deal with any security vulnerabilities that are discovered. If that particular feature is a 'must have' for you you'd need to replace the NVR with a current model that already has the feature.
