Network: Advanced

Advanced Configuration

DDNS: The place to configure the DVR to automatically update a dynamic DNS service. If you want to remotely access the DVR via the Internet, you’ll probably need to configure a DDNS account. See “Network: Advanced: DDNS” on page 39 for details on setting up and configuring the DDNS.

NTP: Network Time Protocol. If you’ve got the DVR connected to the Internet, you can have it automatically sync time with an online server.

Email Settings: Where you can configure the DVR to work with an email account of your choice. This must be correctly configured for the DVR’s auto-email feature to work.

IP Filter: An advanced feature which allows you to exercise precise control over what devices/IP address(es) are allowed to communicate with the DVR and which are not. Recommended for advanced users only.

Server Port: This is the port that the DVR will use to send information through. The most important things are:

•You’ll need to enable UPnP on your router so your router can selectively open these ports, allowing the DVR to communicate via the Internet. If your router doesn’t support UPnP, you have two options. You can either get a new router (which we’d actually recommend - UPnP is such a good feature!) or you can manually forward ports from the router to the DVR. Port forwarding is a technical and involved process, recommended only for the technically inclined.

•Nothing else uses this port. The default port number is 9000, which is not used by many other devices/programs. However, particularly if you have another DVR or DVR-like device, something might be using this port already. If this is the case, change this value to be unique.

•You’ll need to know this port value when logging in from a mobile device or the MyDVR software - so, if you change it, remember what it is!

HTTP Port: This is the port through which you will be able to log in to the DVR.

•Like the server port, it will need to be forwarded properly in order to ensure smooth, latency-free communication. The default value is “85”, as this port is seldom used by other devices or applications. If there is another device on your network using this port, you’ll need to change it to be unique.

•This is the port number you’ll need to remember when logging in remotely from a remote PC via the HTTP interace.

What port number(s) should I use?

If the default port numbers are in use (85 and/or 9000) then the simplest solution is just to keep “adding one” until you find a port which is not in use. So, if 85 is already taken, try 86 or 87.

There’s no “right” port number(s) to use - any port number will work provided the DVR is the only device using it. For this reason, avoid using port numbers 80, 81, 82, 88, 90, and 99 as these are often used by other devices/programs/protocols.

UPNP enable: UPnP makes configuring your network easier and faster. To use the UPnP setting on the DVR, you’ll need a router which supports this feature, with UPnP enabled. Note that many routers which do support UPnP do not come with the feature enabled by default. You may need to ask your Internet service provider to turn it on.

When UPnP is enabled on your DVR and your router, the Ports that the DVR requires to be open for access to and from the Internet will automatically be opened and closed as necessary by your router, saving you the trouble of manually forwarding these ports. If UPnP is not enabled, or your router does not support this feature, you’ll need to forward the ports the DVR uses from the router to the DVR - since this is a technically challenging process; we strongly recommend using UPnP if possible.
