get https://{BaseUrl}/api/v3.0/multiCameras//channels
This endpoint allows you to retrieve the channel info of a multi camera. This information can be used to add a camera connected to the channel to the account using the /cameras endpoint. The channel details are read-only. To manipulate a new camera use the /cameras endpoint. If the cameraId is not empty then it means that the camera is already added to the account. It is important to note that after using the pageSize parameter, the "totalSize" in the response represents the total number of available channels, not the number of channels resulting from the query string.
