Unable to send email from the DX4700/DX4800 Hybrid Video Recorder using email notification.


Notification events trigger but no email is sent to the email address entered into the DX4700/DX4800 HVR. The SMTP Server Test also fails with a “Invalid Username” message.

The DX4700/DX4800 HVR requires SMTP authentication using a username and password, if the SMTP server does not authenticate using user credentials the result will be a relay failure.


Will need to use a SMTP mail server provider which uses username and password authentication.
Example: Gmail.com uses username and password authentication.

When setting a GMail account, please use the following parameters:
SMTP Server – smtp.gmail.com
SMTP **Port – 25
User Name – xxxx
Password - xxx

The SMTP Server Test button should respond with a "Test email sent successfully".

**Note: Depending on your area, ports 465 or 587 can also be used if port 25 fails.
