QVIS CCTV DVR Manual configuration guide by iCCTV Systems


All our CCTV DVRs/NVRs (Digital/Networking Video Recorders) come with networking functionality as standard enabling them to be logged on to via a locally connected device (on the same network) or even over the Internet. This includes smart phones and tablets, using Apps.

The level of functionality can differ depending on the device and App. Most mobile/table Apps allow for live camera viewing only with some of the more advanced DVRs (QVIS “i” Range) allowing for remote playback via a more advanced App as well as live streaming.

If logging in via a PC (via Internet Explorer or a Free Windows Program) all DVRs should allow for full playback and viewing via this method.

Getting Connected

Although we are happy to remotely assist in getting DVRs bought from us set up and connected online, we first ask you to follow this guide the best you can and get back in touch if/when you get stuck as it is relatively easy when you know how.

1 Get the DVR plugged into your internet router

First step is to use the DVRs network/LAN (local area network) port to connect it to your internet router/local home or business network. This can be done by cable, a wifi adapter or powerline adapters (home plugs).

If there is no broadband connection available at the location and you wish to use mobile 3g networks then a 3g router would be a required with a 3g sim card (not provided). This would be separate from any mobile devices you’d be looking to access the DVR from which would require their own 3g/wifi connection.

2 Access the DVRs network settings to configure with the router

IP Addresses are unique numbered addresses for networked devices. Standard routers usually auto assign address information to devices when they connect if enabled on the device.

Semi - Auto Configuration:

When logged into the DVR with the default username and passwords (refer to manual for your DVR) in the Advanced/Settings menu locate the network settings/configuration option. There should then be an option called DHCP which will attempt to auto configure the device in accordance with the router. Saving and exiting the menu after checking this option and even a system restart may be required for this to take effect. Log back into the networking settings to check for re-configured details. 

You should then be able to test successful configuration via an app (via wifi only at this stage) or PC by going to the DVRs newly configured IP address in the web browser (IE). It will likely request that you accept to install something before you can load the cameras (May require alteration of Tools > Internet Options > Security > Custom Level > Download Unsigned Active X controls: 'Prompt' rather than 'Disable').

1 Find and enter your routers IP address as the default gateway

Should you be unable to use the DHCP feature then you will simply need to know your routers IP address. The default address may be printed on the bottom of the router with the wifi key, will likely be in the manual if you have it or you could search online for the model number. If on a windows PC you can go to start > run > type ‘cmd’ or select the command prompt from the menu. > when at the command prompt type ‘ipconfig’ to display the PCs network settings which should list it’s IP address (IPv4) and default gateway (the routers IP Address) at the top. (Type ‘exit’ to exit this screen).

Routers usually have an internal IP address of or or similar and this is the default gateway for devices.

You'll need to login to the router on the next step so you can test if this address is correct by typing it into the address bar in an internet browser to see if the login page comes up.

Please enter this in the DVR as the default gateway.

2 Set the DVRs IP address

When devices connect to a router they need a similar IP address and the first 3 of the 4 blocks of numbers need to be identical. So if a router is then your DVR may be set as or above along with all other connected devices having their own unique ending number. We advise setting the DVR’s IP address as for example so to make sure that the IP address does not already clash with an existing device if the router is auto-assigning ending numbers from 2 upwards.

The Subnet mask usually stays unchanged as does any DNS servers settings.

You should then be able to test successful configuration via an app (via wifi only at this stage) or PC by going to the DVRs newly configured IP address (in the web browser via PC).

What’s an external IP address and what’s mine for accessing remotely?

You should now be able to access the DVR on the same network using its IP address. However this will not work when accessing from the outside world. Even though you now know your routers internal IP address, it also holds an external IP address which is unique to your router and internet connection. Every router connecting to the world wide web will have a completely unique address identifying it and your internet connection. This external IP address is what is needed to access the DVR remotely/from somewhere else along with the correct login details. 

Your external IP address is issued by your internet service provider and you can find out what it is here as it’s not particularly secret when you access a website: http://www.whatsmyip.org/

To throw a spanner in the works, odds are unless you requested or can request a static IP address (usually an option for businesses) this IP address will change every time the router has to reconnect to the internet; if the connection drops or after a power cut for example.

There is a free work around however: if you register for an account at http://www.quickddns.com/  they will let you choose a kind of memorable web address which you can later use to login to the DVR with, rather than an IP address. This service keeps track of your changing external IP address but only if you enter your chosen username and password for this service when regsitered into your router if possible or failing that, if the option isn’t there into the DVR in the appropriate networking section (Look for Dynamic DNS). This will allow your router/DVR to update the web service and your web address, to redirect to the correct IP address when it changes without you having to worry about what it actually is anymore.

Finally the router needs to know to allow your DVR viewing logins in via its secure ‘Firewall’ and to redirect them appropriately to the DVR. This is where port forwarding comes in.

Depending on the model of the DVR you will need to redirect one or two ports which the apps use (37777 & 37778 for example on some QVIS DVRs: refer to manual). Also if you wish to login via Internet Explorer, port 80 can be forwarded for web browser login.

Advanced users: You can change these ports if clashing with another device you have already setup or for multiple DVRs. If the web port is set to anything other than 80 when you login to the device via a browser simply append :81 to the address (assuming you might use port 81) as 80 is the common default and doesn't need to be specified.

The exact process for setting up port forwarding does depend on the make and model of router but it is always much the same. You need to login to the router via a web browser by simply entering its IP address (default gateway) with correct login details.

The location can vary but you may need to go into advanced settings on a Virgin Media hub for example and then go to ‘Firewall’ or ‘Security’ before you see ‘Port Forwarding’ or something similar. If you get stuck finding this it is likely someone else has before with your router and asked this question and had it answered online for something else if you search.

You will have to ‘add’ some rules to forward TCP/UDP ports either individually or a ranging from and too (for two neighbouring ports) 37777-37778 to the DVRs local IP address ( for example).

There are specific apps depending on the model of your DVR but when installed, in the settings you enter your external static IP address/No-IP web address along with username and passwords for the DVR (as well as port numbers if they are different to the standard ones) and this is what should happen:

The App uses internet connection to locate your router using your unique IP or web address and attempts to connect via the pre-defined port number(s) > The router redirects this request based on the port to the DVR where the username and password are used to allow you to view your cameras live from anywhere in the world! (With an Internet connection of course.)
