IP camera

With this function block images from an IP camera can be transferred to the visualization.

The communication with the camera takes place only within the internal network; no port forwarding is required, since the camera is read out by the controller and forwarded to the app over a secure connection.

The communication with the camera takes place exclusively via http or https requests. The camera must also support this. If the web interface of the camera has a snapshot function, this can generally be read out as well. Cameras that can only be displayed via a manufacturer's app cannot be connected. Live stream and audio are likewise not possible.

Inputs
FG	Enable	Optional enable; if the input is not connected, the block is always enabled.
ST	Snapshot trigger	This input takes a snapshot and optionally sends an email as well.
SD	Snapshot reset	Resets the output Number of snapshots. Is controlled by the control element.
Outputs
ST	Status	0 if the request was successful, otherwise an error code (for support only): positive values are the HTTP error code returned by the camera (e.g. 401 = login rejected, 404 = link not found), negative values indicate connection errors (camera not reachable, timeout or invalid link).
SA	Snapshot count	Number of snapshots
Parameters
	URL Http	URL of the snapshot function of the camera. When this URL is called, a still image must be returned.
	User	User name
	Password	Password
	Timeout	Maximum wait time for the request in seconds.
	Verify certificate	Verification of the server certificate for https connections. Disabled by default, since cameras mostly use self-signed certificates.
	HTTP header	Optional additional HTTP headers for the request in the format "Name: Value;Name2: Value2".
	User agent	Optional user agent for the request, in case the camera requires a specific identifier.
Snapshot
	Trigger	Trigger for taking a snapshot, for example a motion detector. A still image is stored and can be displayed via the control element.
	Ring buffer	Number of how many images are stored before the oldest is deleted.
	Delay	Delay between trigger and capture.
Mail sending
	Active	Enable mail sending. With each snapshot trigger an email with the stored image is sent.
	Address	Email address
	Subject	Subject
	Text	Text
	File extension	Extension of the image file, normally png or jpg. The controller itself cannot determine the image type, therefore the extension must be specified manually.
