45The primary requirements for accessing the DVR via the Internet are:A High-Speed Internet ConnectionVideo uses a lot of data, so you’ll need a fast Internet connection in order to get smooth playback andmonitoring remotely. Note that upload speed refers to the rate at which an Internet connection cansend data, not receive it. Most Internet connections are ‘asymmetrical’, which means they candownload data faster than they can upload it. We think that an Internet connection with an uploadspeed of 256 kpbs is generally sufficient for remote access, but ideally upload speeds of 512 kbps orhigher are recommended - particularly for multi-channel playback or monitoring at higher resolutionsand quality settings.Your DVR & Local Network Correctly ConfiguredIt is important that your local network function is correct, and that the information entered into theNetwork menu in the DVR (see “Network Menu”) 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. Some routers can use either method, whilst some only support DHCP,and others only support STATIC. If your router supports it, we recommend using DHCP addressingwith UPnP enabled, 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 gatewayvalues into the DVR - the router will automatically assign these.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 deviceson your network). The most common way of discovering these values is to use a computer alreadyconnected to the network, which can access the Internet.Remote Access |
