I’ve been working on integration with my Synology Diskstation specifically the Surveillance Station cameras. The Diskstation is a network storage (NAS) and media server solution. It also has a full camera surveillance solution.
The integration I have implemented uses local network access to connect to the Diskstation and allows creation of camera devices. The camera devices support taking of pictures, triggering recording on the NAS, and motion detection. Camera movement, presets, patrols, and zoom are also supported. Synology has their own separate DSCam app where you can view live streams and recordings. Synology supports a huge number of cameras which is great (https://www.synology.com/en-us/support/camera). However, the camera system is limited to two cameras without additional license purchase.
You can download the SmartApp and device type here with instructions:
I’ve tested it quite a bit but there still may be some bugs. I don’t have a zoom camera to test that feature, but support should still work.
