NETWORKING 101 – TRH04S Specific (Edit Step 9 to adjust for other DVRs)


1)      Find out if the Internet at the location uses a Static or Dynamic IP address.  If the user doesn’t know contact the Internet Service Provider to determine what type of IP they use.

2)      If the IP is Static proceed to step 3, if the IP is Dynamic you must set up a DHCP through  If you are unfamiliar with how to do this use the walkthrough provided at in conjunction with the Router manufacturer to get it set up.

3)      Go to Start>Run and type in ‘CMD’.  A black screen that looks like the old DOS screen from 20 years ago should come up.

4)      Type in: ipconfig and press enter

5)      Write down the Subnet Mask and Default Gateway

6)      Exit that screen after you have written the information down.

7)      Go to your routers administration panel to where you open ports and assign IP addresses. Consult the routers manufacturer or manual for more information on how to get to where you assign new IPs and open ports.  Each router will have a different way to assign IP addresses and open up new ports.  A great resource for this step is:

8)      Write down the IP address you assigned the DVR and the port number opened on the router.

9)      (TRH04S/TRH08S/TRH16S)On the DVR go to Menu>Main Menu>Network Setup and make sure that the DVR is set to LAN .

9b) (TRH04/TRH08/TRH16) On the DVR go to Menu>Link>Network and make sure that      DHCP is disabled.

10)  Input the information you wrote down into their respective fields.  The IP Address is the one you assigned on the router.  The Subnet Mask and Default Gateways were the two numbers you wrote down from the ‘CMD’ screen in step 3.

11)  Go to HTTP Settings and once there make sure that it’s enabled then input the port number you opened up earlier on the router’s admin panel.

12)  Once you’ve confirmed the information select OK until you’re back to the main menu.

13)  If ALL the information is correct and you still can’t log on via internet explorer check the following:

a.       You’re typing HTTP:// in you’re address bar before the IP address:port #

b.      Go to Tools>Internet options>Security Tab>Custom Level and make sure all active X controls are enabled.

c.       Go to Start>Run>CMD and double check your Subnet Mask and Gateways are what you wrote down.

d.      Go into your router’s Admin panel and double check that the assigned IP and Port numbers are unique and the first three sections of your IP address match the Gateway. (i.e. your default gateway # is your IP that you assigned must be 192.168.1.XXX where the XXX can be any number not already in use or the default gateway)

e.       Double check that all three of those numbers match what you input into the DVR

f.       Do the same for the port number on both your DVR and the Router.

g.      Contact your router/ISP for more information because our DVR is set up correctly.     




Note: There can be many issues that can prevent your DVR from running.  If you have followed the steps on this guide very closely then it’s more than likely an issue with the router, the ISP or even a physical connection
