Requirements For Remote Access - Swann DVR4-1200 User Manual

Requirements for Remote Access

The primary requirements for accessing the DVR4-1200 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 connect
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 home 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 to the documentation
which came with your router to learn which type of IP allocation your router
requires. Most of the time, routers support both allocation methods. In such cases,
we suggest using a STATIC configuration, as it will let you exercise more control
over the functionality of your network, and reduce the need for maintenance.
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 from your networks Dynamic Host (usually your router).
Finding your Network Information
You may be wondering how to find information, such as your Subnet Mask,
Gateway values and DNS servers, as well as the first three parts of the IP address
you'll need to assign the DVR. To do so from a Microsoft Windows based PC:
®
• Open the Start Menu.
• In the Search Box/Run Box (depending on the version) enter "command"
and press Enter.
• An imitation DOS prompt will appear. Type "IPCONFIG /ALL".
• All the relevant information will then be displayed on-screen.
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.
