If you’ve ever tried retrieving CCTV video and playing it back on a standard video player, you’ve probably had the harrowing experience of trying to open these tricky little .DAV files in your everyday, run of the mill video player and… Rats! It just won’t play. Why is that? Because for super-secret-safety reasons that would take hours and endless bar graphs to explain.. these files are usually encoded thus unplayable in your regular old player but there are Options for Converting and Decrypting your CCTV video.

Sadly… you’ll now have to spend an extra few hundred seconds more of your life to decipher them. I know, it’s a drag.. but we’re here to help walk you through it.

Now, depending on the type of camera (whether it be Analog, HD-CVI, HD-TVI, or Network IP) and the DVR, some converters will need more than one pass as conversion to fully decrypt the video. Some might only need one conversion but almost 98 percent of the time (from my own experience) it’s two. Most of the time.. you’ll only need 2 pieces of software to do this, but depending on how often you need to do this, and how many cameras and DVRs you’re dealing with.. having a backup converter comes in handy, just in case (kinda like a fire axe in the glass case . . .  you’ll probably never need it, but you feel fuzzy inside knowing it’s there). Luckily, there are several freeware options for making sure your video is fully converted, decrypted, and useful.

First, you’ll have to scan through your video and find the relevant sections you want to convert, leaving yourself about 30 seconds extra space before and after for safety. This can be done through the DVR user interlace, or via your computer or smart device if you’re dealing with an Network Video Recorder. Once you’ve selected the file, you may have to locate where the file has been sent to… which could be in several different locations, but it’s usually in the C drive directory, where it’s usually stored in a folder “RecordDownload”.

Untitled-5

But it may be in your “Users” folder.. in which case, look in Users/Username/Web/Recordfiles. But if you still can’t find it, just look in your DVR settings for the save / write directory.

Ok, so you’ve located the files… now comes the fun part (ok, not really). Start by going Here and scrolling down to near the bottom of the page to where it says “Video Player and Converter Downloads”, and select download, then run the install file.

Untitled-4

It’s a program simply called “Player” (such a creative name. And yes, I’m being very sarcastic), but it it’s also a handy little file converter that can handle converting your DAV files to AVI video files.

player 3r
To get a video ready to convert, click the “Open file” icon on the left side (the up arrow button), and select a file to upload. Scrub thourhg it to make sure the video is correct, then click on the “AVI” button.

Untitled-6

Select where you want to save your file, then click Convert. Step one is over, but odds are, you’ll have to put it through one more conversion to be able to use it in a a standard video player. Even though it’s now an AVI file, it’s still encrypted. Even some well known video converters, such as Adobe’s Media Encoder can have issues reading these kinds of files. So . . . what are the options from here?

1) Xilisoft Video Converter
Untitled-7

Xilisoft is quite a robust video converter.. sort of a Swiss Army Knife (wielded by MacGuyver) for video, but unfortunately it’s not freeware.. so sadly you may have to purchase it (which is a good thing as it helps keep the economy going strong). Otherwise, it will only convert up to 3 minutes of your videos. However, if you’re okay with this, and the sections of video you’re converting are shorter than that (and really… who wants to watch more than 3 minutes of security video these days), then this software should work just fine. The advantage Xilisoft offers is the sheer number of formats and options that can be utilized. But generally you’ll want to stick with the standard video export formats like AVI and MP4.

2) Any Video Converter (A.V.C.)
Untitled-8
No, not literally “Any video converter”.. that’s actually what it’s called. Sometimes, there are issues converting some types of videos on one converter.. so it pays to have a backup.

That’s how we discovered this piece of software.. a newer camera format (which shall remain nameless to protect the innocent) started producing video files that would sometimes cause Xilisoft to hang and then crash… or they would only convert a few seconds of video, rather than the entire recording.. so, obviously.. this would not do. We needed an alternative and we needed it fast. So.. after a blistering 90 seconds of searching on the inter-webs, we found this handy little program. And much to our delight, unlike Xilisoft’s Video Converter, this one is freeware. While it’s not quite as feature packed as that converter, it allows you to even burn video DVDs of the files from right within the program itself, which can definitely come in handy and expedite the process of producing a hard copy of a video if it’s necessary.

3) FREEMAKE VIDEO CONVERTER

Here’s another freeware video converter that’s has a user interface that’s even more visually simplified than “Any Video Converter” (mentioned above).
But the simplicity of it’s interface is deceptive because it too outputs to dozens of video formats (mentioned above) but it also happens to handle a wide variety of files that may cause other converters to crash. Another thing it shares with AVC is the ability to burn a DVD right from the software, and even add a simple DVD menu if necessary.


And that folks, is about all there is to it. Here’s the simplified Cliff Notes version..
1) use the “Player” software to convert the .DAV file to AVI,
2) The another converter to take out that nasty encryption.
And it just so happens.. we have a handy play by play video on how to do that…

How to set up your DVR for use with a TechProDDNS Domain

One of the problems with viewing your DVR remotely is that if your Internet service Provider or (ISP) changes your IP address, you may no longer be able to access your DVR.  Once properly configured, the TechPro DDNS (Dynamic DNS) service eliminates this common issue.

The way it works is by providing you with a domain name, like the following “MyDVR.techproddns.com”, that will always resolve to your current IP address. If the IP address changes, the DDNS service is notified by the DVR and updates the domain name to point to the new IP. Put simply, you can always reach your DVR by going to “MyDVR.techproddns.com”.

This document will show you how to setup your TechPro Security Products DVR in conjunction with a TechProDDNS domain name. It is important to note that some brands of DVRs may not work with DDNS, but all TechPro Security Products DVRs have this capability built-in.

Step 1 – Register for a TechPro DDNS Account.    

Step 2 – Set up a Domain Name.
Once your TechProDDNS account is set up, you will need to set up your domain name.

DDNS_Info

In the example above we chose the domain name “MyDRV.techproddns.com”, User ID: UserID1 and a Password: Password1.

You can choose any Domain Name, User ID and Password that you like, but they should be unique for each DVR.

Note: In Step 3 (the next step) you will have 2 options for configuring the DVR.

Option 1 is using the DVR Local interface and Option 2 is using the “Web Service” via Internet Explorer.

 If you use option 2, the web service, you must have the web service ActiveX Add-on, properly installed on Internet Explorer and your DVR must be on the same network as the computer you are using to access it.

Step 3 – Setup your DVR

Option 1 – DVR Local interface.
With a monitor and mouse connected to your DVR, login to the DVR Local Interface.

20131209_135318

Select “Settings” icon from the Main Menu.

2

Next Select “Network” icon.

3

Note: The example below assumes that your network IP scheme follows the 192.168.1.? Convention. This is normally the case.   It also assumes that your Default Gateway (typically your router) has an IP address of 192.168.1.1

5

 

TechPro DVRs come with a default static IP address of 192.168.1.108. This is normally fine and for the purposes of this document we are going to leave it that way. Do not check DHCP as we want this DVR to ALWAYS have the 192.168.1.108 IP. If DHCP is selected it may pick up a random IP from you router.

Note: Just be sure that 192.168.1.108 is not in your routers DHCP range. If it is another device on that network may get 192.168.1.108 assigned to it and cause conflicts.

We also recommend that you change the HTTP Port from the default 80 to 88. Port 80 is the default HTTP port for many devices and may also be blocked or cause conflicts.

Once you are done scroll to the bottom of the page an turn on the checkbox, next to “DDNS”.
Then double click on “DDNS” to open the DDNS Settings.

8

Select “Dyndns DDNS” from the “DDNS Type” dropdown and turn on the “Enable” checkmark next to it. Now enter the following information.

Server IP: techproddns.com
Port: Do Not Change this. Unlike the HTTP Incoming Port, this should remain 80
Domain Name: MyDVR.techproddns.com
User Name: UserName1
Password: Password1

Select “Save” at the bottom of the “DDNS Settings” popup and “Save” at the bottom of the “Network Setting” Page.

 

Option 2 – Web Service (via Internet Explorer).
The setup is identical to the setting above but, the user interface of the web service is a bit different. In Internet Explorer go to http://192.168.1.108, and login to your DVR.

WEB

Next Select “Network” from the navigation bar on the left.

Untitled-2

Note: The example above assumes that your network IP scheme follows the 192.168.1.? Convention. This is normally the case.   It also assumes that your Default Gateway (typically your router) has an IP address of 192.168.1.1

TechPro DVRs come with a default static IP address of 192.168.1.108. This is normally fine and for the purpose of this document we are going to leave it that way. Do not check DHCP since we want this DVR to ALWAYS have the 192.168.1.108 IP. If DHCP is selected it may pick up a random IP from your router.

Note: Just be sure that 192.168.1.108 is not in your routers DHCP range. If it is, another device on that network may get 192.168.1.108 assigned to it and cause conflicts.

We also recommend that you change the HTTP Port from the default 80 to 88. Port 80 is the default HTTP port for many devices and may also be blocked or cause conflicts.

Once that is done, scroll to the bottom of the page and check the box next to “DDNS”.

Select “Save” at the bottom of the page.

Now Select “DDNS” under the “Network” Menu.

Untitled-3

First select “Dyndns DDNS” from the “DDNS Type” Dropdown and check the “Enable” box next to it.

Now enter the following information:

Server IP: techproddns.com
Port: Do Not Change this. Unlike the HTTP Incoming Port, this should remain 80
Device Alias: MyDVR.techproddns.com
User Name: UserName1
Password: Password1

Select “Save” at the bottom of the page.

Step 4 – Port Forward your Router to your DVR.
OK, now you have configured your DVR to communicate with the DDNS server and keep it up to date with your current IP address.

The last thing we have to do is set up port forwarding in your router. Doing this tells the router that when a request comes in from “MyDVR.techProDDNS.com” on port “88”, to forward us to the DVR.

The user interface may vary depending on the specific router, but port forwarding is usually set up similar to this example. Here I am using a Linksys E1000 wireless router as shown below.

rOUTER

Most routers will have options for “Single Port Forwarding” and “Port Range Forwarding”.  In this example we will use “Single Port Forwarding”.

You may have noticed earlier, when we changed the “HTTP port” to “88” that there was also a “TCP port” set to “37777”.  We will need to port forward both of them. The HTTP port (88) is used by the “Web Service” when accessing the DVR from a browser, like Internet Explorer and the TCP port (37777) is used by software or mobile apps that will be accessing your DVR.

Once you find the area in your router for “Single Port Forwarding”, you will want to set things up similar to the settings shown above.

First, you will assign a descriptive name to each port forward. I used “DVR Web” for port”88” and “DVR Software” for port “37777”.

In the “External Port” and “Internal Port” fields you want to specify the port that the request will be coming in on “88” or “37777”.

Under the “Protocol” drop down there are usually 3 options, TCP, UDP and Both. We really only need to select “TCP” but selecting “Both” won’t hurt and covers all bases.

Now you need to tell the router the IP of the device you want to forward your request to. In this case it’s the DVR “192.168.1.108”. That’s why earlier we mentioned we do not want to check the “DHCP” option, this will ensure that the DVR is always “192.168.1.108”.

Last, you want to “Enable” or make sure this rule is “Active”.

 

Testing To See If Everything Works.
At this point if everything is setup correctly, you should be able to test it by launching “Internet Explorer” and going to the following domain:

HTTP://MyDVR.techProDDNS.com:88

If you get the “Web Service” login screen, then it’s all good!

WEB

One Last Note: Notice that we had to specify: 88 at the end of the domain name. This is because we change out HTTP port to 88. If we did not add: 88 the router would not know which rule to use to port forward our request.

NAT and Port Forwarding Part 2

How do I know if I have Double NAT or Triple NAT?

In my last article we talked about NAT and what it does, and Port Forwarding and what that is. This article is the second in that series.
It should be easy enough to get your DVR/NVR up and accessible on the LAN (Local Area Network) by inputting a valid LAN address in the DVR/NVR setup. Now the question is – how do we make it accessible from off site. I mentioned in the previous article – while we were in the router, we should check for it’s ‘External IP Address’ to see what is showing there. This is usually in the ‘Status’ section or ‘WAN’ setup. Now you will need to know what you found there. The WAN or Internet status will tell us a couple of things.

1. Is it a static or dynamic address? If you see something like ‘DHCP’ / ‘Obtain Automatically’ / or you just can’t find an address anywhere, then most likely the address is dynamic. For Port Forwarding purposes, we don’t want anything to be dynamic unless it absolutely has to be. In a dynamic address scenario, your IP address can change, and then your Port Forwarding is broken. If your router shows ‘DHCP’ or ‘Obtain Address Automatically’ it may not show the address it has. This then, becomes a little tricky to figure out.

A good way to test for Double/Triple NAT, if you are comfortable working in the DOS Command prompt – run a ‘tracert’ command. (Trace Route) Trace route shows every node , or device that you pass through on your way to a certain web site. (Try it on your favorite web site sometime – you might be amazed at how far your signal travels to get to a site that is physically hosted only a few miles away) The first ‘hops’ it shows may reveal Internal Addresses replying. This is a clear indication of how many routers you are passing through on your way to the Internet. To run a trace route command – open the Command prompt and type “tracert www.yahoo.com” without the quotes, and be sure to leave a space between tracert and the www (you can use any site you want, I just always use Yahoo or Google). To open a command prompt – Press and hold the Windows ‘Flying Flag’ key between Ctrl and Alt on your keyboard – this will pop up a ‘Run’ dialog. Type “cmd” (without quotes) and click Enter. This will open your Command Prompt. Then just type in “tracert www.yahoo.com” (without quotes) Make sure to leave a space after ‘tracert’. That will return a series of IP Addresses similar to this =

tracert

As you can see, the first hop shows 192.168.2.1 (Class C Internal Address) The second hop shows an address of 96.88.74.138 (NOT an Internal Address) and it also shows Comcast information as well, confirming that it is an External Address. This shows me that I have only one router in line before I get to the Internet, so only single NAT on my system. If you see two or three hops showing an Internal Address, then you have Double or Triple NAT or Quadruple NAT or…? The point being, if you see more than one Internal Address, your task just became a little more difficult.

Another method, if you can do it without taking the customers business offline, unplug the Cat-5 cable coming in to the ‘WAN’ or ‘Internet’ port on your router, and plug directly in to your PC. Restart your PC, then run an ‘ipconfig /all’ command from a DOS prompt and check the IP Address you find there. (Try to connect to the Internet with a browser to verify you are getting a valid address when you test this way.) Hopefully you will see an ‘Internet Address’, then you know there is nothing else in line to worry about. If, however you see an ‘Internal Address’ Make a quick note of the IP Address, Subnet Mask, Gateway, and DNS Servers you see there – we can use them in the router you are connected to. As soon as you have the information you need, pull that cable and disconnect from the Internet. (It is risky to connect directly to the Internet so keep your test as brief as possible)

2. If you see the IP address is set to ‘Static’ in your router, you WILL be seeing an IP address. Check to see if that IP address is a ‘Private Range’ address =
Class A = 10.0.0.0 through 10.255.255.255
Class B = 172.16.0.0 through 172.31.255.255
Class C = 192.168.0.0 through 192.168.255.255
When you see this on your WAN status (or WAN Address or Internet Address) –There is another device in line between you and the Internet that is performing NAT and you will have to Port Forward that device to the device you are looking at. To accomplish this you will need to set the router to a ‘Static’ address. The quick and dirty way is to take the IP address , Subnet mask, and Gateway that you discovered in the test above (connecting the routers’ WAN cable directly to your PC) and use them in the router you are working on. For DNS servers, use the ‘Gateway IP address’ or whatever you saw in the ipconfig test. (If you ran ‘ipconfig /all’ you will see DNS servers listed)
It is important to know that a modem with only a single LAN connection can also be a router. Even if it has only one port to connect to, it can be performing NAT and you’ll need to Port Forward it as well. (This is not usually the case on a cable connection – cable modems are generally set to ‘Bridge Mode’ so they are transparent on the network) This is where the ‘Status’ page of a router helps, if its WAN address is a private IP address, then your modem is also a router and it is supplying that address. Or , even more common, you will find another router in line between you and the Internet.

The easiest test here is to look for the ‘Gateway’ address showing on the WAN status. The gateway you see there will be the next router in line. Put in that address and see if you get a logon prompt. If you see another router, log into it and then run the same tests to see if it is directly connected to the Internet or not. Keep going until you no longer see private addresses on the router’s WAN connection. Start making a diagram of what you find and the different ranges of IP addresses you see on each one. You will need this information to map out your port forwarding. If you find only one router, you are golden – port forward it and call it done. If you find two or three routers in line – you are going to have to port forward every one of them.

Ports are forwarded directionally from the Internet toward your device.
The important thing to remember in Port Forwarding is that you must forward in ‘Daisy Chain’ fashion through all devices in your path.
Port Forward your ports from the modem to your first router – from your first  router to the next router – and so on until you get to the router where your device is connected. That last router will then be forwarded to your device.
**The most common mistake in port forwarding is to try to forward the first device in line directly to the camera or DVR IP Address instead of porting through the chain of devices.

Double NAT or Triple NAT can be tedious to set up because it takes extra time and you need to be sure of the connection sequence of your devices, and in some cases, you may find the customers network is not set up correctly. In my next article I will show you what to look for and how to fix it, as well as a detailed example of how to ‘Port Forward’ through a series of routers.
Happy Networking!

NAT and Port Forwarding

Written By:

NAT and Port Forwarding
What is NAT and what does it do?
NAT is Network Address Translation. There are different types of NAT, but we’ll stick to the easy non-technical explanation of ‘Many to One’ NAT.
Your router is a Gateway, or ‘door’ to the Internet. There are two sides to the router, the External (WAN) side and the Internal (LAN) side.
Your computer should be connected on the inside (LAN) with an Internal or private address.
Your computer will only communicate with IP addresses that are on your same subnet. (Address range)
Everything on the outside of the router uses different IP addresses and Subnets – the router allows you to communicate with other devices in other subnets.
OK, so what does all of that mean?
Your computer can not communicate with another computer that does not have an address in the same ‘subnet’.
The router ‘translates’ different subnets for you, allowing you to communicate outside of your subnet.

NAT serves three main purposes =
1. Provides a type of firewall by hiding internal IP addresses.
Even though your computer shows an address of 192.168.1.115 – when you browse the Internet – your address shows as something entirely different to any Internet computer.
Your routers’ External address is what shows up. This is also called ‘IP Masquerading’. This helps keep your computer ‘anonymous’ on the Internet.

2. Enables a company to use more internal IP addresses.
Since they’re used internally only, there’s no possibility of conflict with IP addresses used by other companies and organizations.
A company using a hundred computers or more only needs 1 Internet address. Internal address ranges are hidden from the public and are not part of the Internet address scheme.
This is where the term ‘Many to One’ comes from. Since the router is the only connection to the Internet, it’s address is the only one visible to the Internet. 100 or more computers using that router show up as 1 single address to the Internet (Many addresses to One address)

3. Allows a company to safely set up a device on the Internal Network for access from the Internet.
Using ‘Port Forwarding’ allows a company to set up Internet access to a device on the LAN. The porting guides the incoming signal to the correct device. The benefit of this is the Internet user sees only your ‘Public IP Address’ (your modem or router) and can not see your ‘Internal IP Address’ so they have no direct access to the device other than through the software they are using to access it. (IP Masquerading again)
So, in a nutshell – NAT allows you to ‘see’ other IP Subnets while keeping you anonymous to those other networks.
Now you have a very basic understanding of what NAT is and does, and hopefully, you already know how to set an IP Address on your LAN so your device can communicate.
So how do you set it up to be accessed from the Internet? This is where ‘Port Forwarding’ comes into our picture.
When you are accessing your device from a remote location, in 99% of all instances, you will actually be accessing the router or modem. The router then guides your incoming signal to the correct device on your LAN. The only exception to this rule will be when your device is set with an Internet IP Address and exposed directly to the Internet. This is always risky – and this is why Internet Security companies make the big bucks. Putting a Windows based computer directly on the Internet with no protection is an open invitation to bad things happening, and bad things WILL happen within a very short time. We tested a PC connected to the Internet with an External address – in 45 SECONDS we had been infected with SQL Slammer virus. (This PC was running Microsoft SQL with listening ports set to defaults) So protecting your computer from the Internet is important, to say the least. This is why you need a router to ‘mask’ your computer and hide it.

So, how does your remote query to 74.93.230.34 end up connecting you to a device with an address of 192.168.1.120? The answer is ‘Port Forwarding’. My favorite analogy to describe a router is to think of it as a Hotel. The Hotel has a ‘Street Address’ – the same as your routers ‘Internet Address’ The rooms in the Hotel all have different numbers – the same as computers on your LAN.
When you send mail to the Hotel, you send it to the ‘Street Address’ of the Hotel. If you don’t have a room number or customer name – the Hotel does not know where to send that incoming mail. You can’t add an Internal IP Address (room number) to an Internet query, so you’ll need some other kind of information for the router to direct your incoming signal. Ports provide that extra information for your router.
Setting up Port Forwarding is pretty easy when you have all the necessary information.
You will need the IP address of the Router to access it for programming.
You will need the IP address of the device you are forwarding to.
You will need the port numbers required by the software.
The hard part is figuring out where to go on the router to get it set up. You will find that different models of routers sometimes use completely different terminology for the same thing. To set up port forwarding on your router, look for ‘Advanced Configuration’, ‘DHCP’, ‘NAT’, ‘Applications and Gaming’, ‘Virtual Servers’ or ‘Pinholes’ depending on the router model and manufacturer.
Sometimes they actually call it ‘Port Forwarding’, but you’ll usually find it hidden in one of those other sections.

On a Linksys router – look under ‘Applications and Gaming’
LinksysAppsGaming

Here you can see the information requested –
Application = call it what ever you want, but use something descriptive in case you have to come back for a service call a year later.
Start = The starting port or lowest number port in a range.
End = The ending port or highest number port in a range.
(If you are only forwarding two ports, 80 and 37777 for instance, then create two entries instead of a range – Start Port = 80 / End Port = 80 for the first one and Start Port = 37777 / End port = 37777 for the second one. Avoid using a range when the port numbers are so far apart. In this case entering a range of Start Port = 80 / End Port = 37777 would work, BUT you would be opening over 37000 ports. That is a security breach just waiting to happen.
IP Address = the Internal IP address of your device.
Enabled = Turn it on !
Save = Always look around for a ‘Save’ or ‘Apply’ button – if you forget or miss it – the router may ‘dump’ all your hard work and you’ll have to do it all again..
While you are logged in to the router, try to find the WAN status or Internet Address. This will tell you if you are connected directly to the Internet or if you are routing through another device, such as another router or a modem that is also routing. (A modem with only one network port can still be a router, handing out a private address range.)
If you see an address there that falls into the “Private” range of addresses, then there is another device between your router and the Internet performing NAT and you’ll need to Port Forward that device as well. When you have more than one router to pass through before you get to the Internet, then you also have a situation called Double NAT or Triple NAT, where each router is translating for it’s unique subnet. When you have a double or triple NAT situation, then you also have to do double or triple port forwarding to route your incoming signal back to your device.
In my next article, I will show you how to discover Double NAT and Triple NAT situations, and how to map your way through them to establish Port Forwarding. Happy Networking!

What is a DDNS and how to setup a free TechPro DDNS account?

Written By:
Sunday, April 19th, 2015

When we sign up for an internet service, our internet provider assigns us with a unique numerical label which is called an IP address. This IP address is a must have if you want your devices to communicate with the computer network. The IP address serves two functions, network interface identification, and location addressing. Every time we are connecting to the internet using a modem, we are assigned an IP address that is available and not taken by other users. Although you may get the same IP address as a previous connection, often you’ll be assigned a different IP address each time you connect. When internet providers were “born”, everyone connected to the Internet over a modem and most people used the Internet for a few minutes to a few hours per week. Assigning a static IP address to every consumer would have been very pricey for something that most of us used just a few minutes a week, so the providers started assigning the customers with dynamic IP addresses. When modern providers enforce dynamic IPs these days, it may be in part to differentiate between “consumer” and “professional” services, reserving static IPs for customers who spend more for their services.

So what happens if the customers purchased and installed a CCTV system at his residence or his business and wants the option of remotely accessing the system to view his cameras? One option is to contact his Internet Service provider and purchase a static IP address that will be assigned only to him. The second option is to sign up with a DNS. What is a DNS (Domain Name System)? In simple words, it is a naming system for computers. It translates domain names, which can be easily memorized by humans, to the numerical IP addresses. Based on the same idea they came up with DDNS (Dynamic Domain Name System) service. DDNS updates a DNS server with new or changed records for IP addresses without the need for human intervention. This allows a fully qualified domain name that never changes to be associated with a dynamically assigned IP address that can change quite often. Let’s take an example . . . when you sign up with DDNS service, they ask you to come up with a domain name, let’s say that your new name is: ‘john.dyndns.com’. This domain will be tied to your dynamic IP address that your internet provider assigned to you. The next time your IP address changes for any reason, the domain name will update itself automatically. The DDNS service solution has two main advantages: You don’t have to remember numbers, only your domain name and you don’t have to be concerned when your ISP changes your dynamic IP address.

There are many good DDNS services like Dyn DDNS, Private DDNS, No-IP DDNS, Quick DDNS and CN99 DDNS. They are all supported by our equipment and a choice to choose is yours only. But you will probably say: “Wait, won’t the service cost me money?” Well……No! The customers of “Security Camera King” will get that service from us for free. Each customer that will purchase a DVR or NVR from us will get the DDNS service free of charge. In the next paragraph, I will explain how to set up a free DDNS service with us and utilize it for your system.

The first thing a customer should do is to go to techproddns.com and fill our simple form. Shortly after, our support department will set you up with an account and you will receive an email that will notify you that the account was created.

After the account is created, go again to the same page: techproddns.com and on the bottom of the page click to login into the account. The account will ask you to create a new domain name and a password for the domain account. Try not to confuse the DDNS account password with the domain password. The domain password is the actual password that you will need to set up on your DVR.

The domain setup will give you a confirmation “Your domain was successfully created” and the page will show all the information about your domain including your IP address that is assigned to you right now by your ISP. Be advised that “Security Camera King” gives you one free domain per one DVR or NVR unit that you buy. But if you purchased more than one unit, there is an option on the same page to create additional domain names. You can also get into the domain menu by clicking the domain name and on that page you can edit your domain names, delete and recreate domain names if you forgot your passwords.

It’s time now to go to your DVR or NVR and login into the ‘Main Menu’. Under the ‘Setting’ tab you will select ‘Network’ and click ‘DDNS’ on the right side of the menu. Follow the next screen shot to setup the DDNS menu and remember to enable only the DDNS that you are setting up.

You are all done and ready to use your domain name. Remember that you are using a domain that replaces your external IP address and you still have to use it as you are using an IP address, which means that you have to use it only when you are trying to access your CCTV system from outside the network. Also, remember to use the HTTP port when using an Internet Explorer web-interface on your desktop or laptop computer to access your system. It should look something like this: http://test-ddns.techproddns.com:88/ (if your HTTP port is 80, you do not have to enter it after the colon).

If you still have problems with setting up your DDNS service, you can always call us at 866-573-8878 to help you out.
