    Set low resolution video stream to


    Set high resolution video stream to


    Set Snapshot HTTP path to


    Enable SIP.

    After this manually add HTTP switch and in service settings set following parameters:

    Set OnHttpPath to /fcgi/do?action=OpenDoor&UserName=admin&Password=xxxx&DoorNum=1 - please note that there is necessary to use correct password as you set it before in device.
