Remote Access
The primary requirements for accessing the DVR16-2600 via the Internet are:
A High-Speed Internet Connection
Video uses a lot of data, so you’ll need a fast Internet connection in order to get smooth playback and
monitoring remotely. Note that upload speed refers to the rate at which an Internet connection can
send data, not receive it. Most Internet plans are ‘asymmetrical’, which means they can download data
faster than they can upload it.
We think that an Internet connection with an upload speed of 256kpbs is generally sufficient for
remote access, but ideally upload speeds of 512kbps or higher are recommended - particularly for
multi-channel playback or monitoring at higher resolutions and quality settings.
Your DVR & Local Network Correctly Configured
It is important that your local network function correctly, and that the information entered into the
Networking menu in the DVR (see page 22) matches the general network settings.
The first thing you’ll need to determine is whether your router requires devices to use fixed (STATIC)
or dynamic (DHCP) addressing - you’ll need the documentation which came with your router to learn
which type(s) of IP allocation your router supports. Some routers can use either method. Some only
support DHCP, and others only support STATIC. If your router supports it, we recommend using STATIC
addressing, as it makes locating the DVR from other devices on your network easier.
In a DHCP configuration, you do not need to enter the IP address, subnet mask or default gateway
values into the DVR. Rather, the DVR will automatically request this information form your networks
Dynamic Host (usually your router). The downside to DHCP addressing is that the IP address of the DVR
will change over time (at least whenever the DVR or router are reset) making the DVR more difficult to
locate and access over the LAN.
For a STATIC configuration, the DVR needs to be told what IP address to use (this must be unique) and
the subnet mask, gateway address and DNS server address (these must match the other devices on
your network).
The most common way of discovering these values is to use a computer already connected to the
network, which can access the Internet. Typically, this is a matter of bringing up the Properties window
for your local area connection (LAN). Depending on your operating system, there are different ways
to do this.
Once you’ve found the network settings on your computer:
• Set the gateway, subnet mask and DNS server addresses to match those that your computer
uses.
• For the IP address, the first three groups of numbers should be the same, with the last being
different (unique). For example, if your computer’s IP address was “192.168.1.12” then you could
set the DVR’s IP address to “192.168.1.235”. (The choice of “235” is somewhat arbitrary - it can
be anything between 0 and 255, so long as no other device on your network is using that address.
We suggest 235 as it is usually available.)
Port Configuration
The DVR16-2600 needs two “ports” to be available and properly configured to work correctly over the
Internet. One of these is called the “Media Port” and the other is called the “Web Port”.
Media Port: The default value is “9000”.
Web Port: The default value is “80” - we strongly suggest changing this as “80” is a port frequently
used by various programs (in fact, it’s the default HTTP port). Generally, “85” is a much better choice
- however, you can set this to be anything that you want, just be sure to remember it! You’ll need it
later.
Remember: these ports need to be forwarded from your router directly to the DVR. Without these
ports forwarded properly, remote access will not work.
