Per Arecont's documentation, for some of their cameras to operate in ONVIF mode, they are required to sync to an external NTP time server, due to a hardware limitation of having no onboard clock chip.

Go to and verify the model you have supports ONVIF. If it does not, it will not be compatible with Arcules.

  • Note: Not all firmware revisions support ONVIF (Profile S).

  1. Use this HTTP command to confirm if it is enabled

  2. Download and install Onvif Device Manager.
