Alarm Notification Email Clips

DW Spectrum® IPVMS can be configured to have the DW Spectrum® Server send an email notification to specific Users and/or Roles whenever an assigned Event Alarm is triggered (i.e. motion detection, detection zone, etc.).

One of the optional features that can be included with an email notification is a short pre-alarm video clip from the camera that the Event Alarm is assigned to. However, if a clip is sent over SMTP (Simple Mail Transfer protocol) and the video clip does not display properly or shows a distorted image, it is likely that the Server is not using plain-text in the emails.

This article will outline how to enable the Send plain-text emails setting for a DW Spectrum® Server.

Supported/Affected Devices:

  • DW Blackjack® Server Series
