Camera Archive

The »Camera Archive« logic element retrieves a current snapshot image from a network camera and stores it in the configured camera archive.

This camera archive is no replacement for a security system. It is also not intended for constant, unrestricted recording in very short intervals. Use the archive in conjunction with event-based triggers such as motion detectors.
Please note that you should not record more than one image every ten seconds. Please also note that having a very large number of archived images will increase image load time in the visualization elements.

Configuration

Target Camera Archive

Choose a camera archive where camera images retrieved by this Logic Element will be stored. Camera archives can be configured in LOGIKEDITOR at System > Settings > Camera Archives.

Protocol

Choose a protocol (HTTP or HTTPS) to be used to connect to the camera. Only select HTTPS if your camera supports it. For HTTPS, you can also set at Certificate Check whether or not only cameras with signed and valid certificates are accepted.

Image URL

Insert the image URL of your network camera. The entire URL can be copied into this field. The protocol will then be identified and automatically stripped.

Image Format

Set the format (.jpg, .png oder .gif) of the images provided by your camera. Retrieved images cannot be saved if the format set here differs from the format of those images.

Authentication

If either Basic or Digest authentication is needed to access images from your network camera, it can be configured here. Authentication credentials can then be provided at User and Password.
