To one space you can add:
up to 200 standalone cameras, including third-party and Ajax cameras;
or up to 14 Ajax NVRs with a total of 224 channels. Both 8- and 16-channel NVR versions can be used.
Each camera or NVR can be added to only one space.
Third-party cameras require an Ajax hub for connection and can transmit only an RTSP stream without access to the archive.
