Please check which technology does your DVR support and the resolution as well. Make sure to match the same setting and technology on the camera so that they can be compatible. Make sure to remove the power of the camera and plug it back in so it can apply the settings. Note: Our XVR series of H DVRs are 5-in-one technology, so they can read HD CVI, TVI, AHD, Analog and IP cameras. If the camera is varifocal check zoom/focus.

Tip: Depending on the email provider, it might be necessary to enable the account to allow third party applications to use the email services, here we show you how to do it on Google accounts:

  • Go to your Google Account settings.
  • By default, this option is OFF, so you have to turn it on for email notifications to work.
  • Make sure to set up the DNS servers on the DVR since they will need to resolve the SMTP server that you use on the email notification settings. You can set this in: Main Menu>Network>TCP/IP.
