If you want to display all three channels in Surveillance Station, you will need three licenses.
For example, you can add as many as three lenses to Axis Q3709-PVE, which allows you to stream up to three channels. For fixed lens cameras with independent IP addresses or removable lens cameras, you will need one license per channel. Most fixed lens cameras providing more than one stream at a time require only one license per camera. There are two types of multi-lens cameras: fixed lens and removable lens. Each regular and panoramic camera requires one license only. Certain panoramic cameras (e.g., Axis M3007) supporting on-camera dewarping may provide more than one stream (e.g., Quad View, Double Panorama, and Original View) at a time.
In the table above, you can see a detailed example of four different camera types.
