i have a dynamic ip address and want to set up my DVR for remote cctv viewing...help

Some DVR's have DDNS capabilities built in... I am shopping for a security system and DDNS is one of the major selling points... if all else fails RTFM...

You must choose "Static" on the DVR

For example, you first choose DHCP on the DVR to automatically obtain the proper settings such as DNS, Subnet Mask Default Gateway etc... Write these down. Then choose Static IP on the DVR and manually enter all of the DHCP settings "except the IP Address" The IP address needs to be changed to an IP OUTSIDE of the range of the DHCP such as 103 if the DHCP is Default Gateway - 192.168.2.1 / Beginning 192.168.2.2 with a maximum of 100 this would leave 192.168.2.2 to 192.168.2.102 as the range for DHCP leases. You need to choose a Static IP outside of this range such as 192.168.2.103to ensure the IP does not conflict or change when the DVR reboots or another CPU is issued an identical IP address. You can get this information from the router itself while logged into the main page. It tells you the maximum, just need to know a little math =) To ensure the Static IP you choose is not in use go the the START Button and click Run and Type CMD or Search and Type CMD. On Run it will pop up, on Search you have to right click CMD and choose "Run as Administrator" after Windows finds it. Type PING*space*192.168.2.XXX it should NOT Respond. If it does that IP is in use and you have to choose another. (Do this before you Port Forward). You may need to unplug the DVR from the Router while you do this, then plug it back in.

Each Port needs to be forwarded to the Chosen Internal Static I

Remember to forward ALL ports required. Sometimes you can have more than 1. Example (Port 9000 - Media) (Port 7777 - Command) (Port 80 - HTTP) (Port 0100 - Mobile) Refer to your DVR manual under "Network" for specifics. Remember the IP needs to be Static on your DVR.

Go to http://portforward.com for a list of routers and specific step by step directions on forwarding ports on your router.

Adjust the Bandwidth Setting

Ensure that the Bandwith setting on your DVR is set at or below the maximum allowed bandwidth for the DVR locations ISP. Example: Contact the ISP and get the Bandwidth setting (256k, 384k, 512k etc.) and set the DVR at or below this number or it may not load at the offsite location. Some DVR's only allow access to this setting via the web interface. Access it locally while plugged directly into the router by typing in the DVR's Static IP in you web Browser (usually only Internet Explorer works) to access the DVR and change the setting there.

Operating System Issues

Most DVR's do not work with MAC unless there is a parallel Windows Operating System installed and Internet Explorer is used.

Bridging the Router

It is suggested that the Router have a "Full Bridge" to the Modem. If you can plug directly into the Modem and access the Internet you are halfway there. Contact your ISP and have them remotely access your "Laptop" that is plugged directly into the Modem. They need to do some specific setting adjustments this way. They will guide you through the process of setting the router up also. Just make sure you insist on a "Full Bridge" between the Modem and Router and ensure that you can access at least 3 websites from the Modem "with the Patch Cable plugged in" YOU MUST USE A LAPTOP to do this.

Have you read the guide? It won't tell you exactly how to configure each device, since without access to one we can't do that, but it gives you the details and where to get help.

In very simple steps:

1. Forward port 80/TCP on your router to your DVR - the guides on PortForward will walk you through that with screenshots
2. Configure the DVR either with a fixed IP on your network, or configure the router to provide the same IP (known as a static lease) to it
3. Either configure your router or your DVR to perform updates of your chosen hostname
