Whats added? App limitations
The DS220j model supports Plex and offers better H.265 support, making it suitable for media streaming. However, it lacks features such as Hybrid Share, Replication Service, Snapshot Replication, BTRFS, Active Backup for Business, Docker/Container Manager, Hyper Backup Vault, Presto File Server, Synology High Availability, Synology Mail Server, and Virtual Machine Manager.
On the other hand, the DS223j model addresses some of these limitations by providing Hybrid Share, Replication Service, Snapshot Replication, and BTRFS support. It also supports Plex but lacks information regarding better H.265 support. Additionally, both the DS220j and DS223j models feature built-in NPU for lightweight AI applications.
In contrast, the Plus Series NAS models offer a more comprehensive set of features. They support Plex, have better H.265 support, and provide functionalities like Hybrid Share, Replication Service, Snapshot Replication, BTRFS, Active Backup for Business, Docker/Container Manager, Hyper Backup Vault, Presto File Server, Synology High Availability, Synology Mail Server, and Virtual Machine Manager. These models offer a wider range of applications and capabilities compared to the DS220j and DS223j models.
It’s important to consider these limitations when choosing a NAS device based on your specific requirements and the applications you intend to use.

Eddie ..Thankyou for relying. I`m assuming from the information that probably all Synology NAS DS units are capable of supporting RTSP using Serveillance Station. I appreciate your input. Thanks.
