 Where do I start for remote access to my video security system?

It is important to view your cameras on your phone and tablet so that you can keep an eye on your assets.  Downloading the TechProSS application is the first step in making this a reality.  If you own an iPhone, you need to use the App store or iTunes to download the program to your phone.  There is a TechProSS Lite or TechProSS Plus that you can download for your phone.  Compare the features and see if the $5 one-time fee for TechProSS Plus includes features that you will need compared to the free Techpross Lite version.  The Lite version contains a majority of the features, and most people will not use the additional features.  However, if you want to support the development of a maturing program, the paid version will help out in that respect.  There is an HD version for iPad that fits the bigger screen and higher resolutions.  If you own an Android phone, then you will need to use Google Play to search for TechProSS.  There will also be a lite version, a plus version, and an HD version for the tablets.  Whichever version you choose, they will look and feel the same.  This article is going to focus on the Lite version, which is what most people will install or start with.

The network needs to be set up and port forwarding needs to be done!

If you want to view cameras on your phone, the port forwarding needs to be set up in the router.  Let’s just say for the purpose of an example that your router takes a Gateway address of, and your DVR takes the default address of  Make sure that your DVR is set to static and NOT Dynamic / DHCP.  You would then need to forward the default TCP port of 37777 to the IP address of  It is extremely important for the DVR to be on the same network as the Gateway.  How do I know what address my Gateway is located?  Good question!  You can open a DOS box in windows and type “ipconfig” to find your Gateway address.  It will also show the IP address that your computer is connected to the Gateway.  If you have a cable modem at a network, you can then set the IP address of your DVR to for example.  If you need to know if that IP address is available on your network, you can ping using a DOS box terminal window to see if anything responds.  The traffic from the internet needs to go through the router straight to the DVR using the port you specify.

The networking part is done, so let’s move on to the configuration.

How can I view my cameras in TechProSS mobile software without having to select each camera every time I run the application?

You can add cameras to a favorites group. Once you create a group of cameras, you can then load your group at the Live Preview screen by pressing the star and hitting the play button. You can create many groups and name them what you like so they are easy to find.

Connecting to your DVR through a network or the internet

The DVRs that we sell here at Techpro Security are user friendly and have a wide variety of features that allow you to customize them for the specific requirements of your installation. One of the more interesting features of our DVRs is that you can access them through the internet once you have them set up correctly to work with your network and get some ports forwarded. This means that you can go on vacation and still be able to log into your DVR in order to view your live camera views or recorded footage, as long as you can get to a computer with an internet connection. You can even use a smart phone for this purpose. Giving you this ability is just another way that security cameras can help bring you some peace of mind, by allowing you to always be able to view the location that meant enough to that you protected it with a security camera system.

Setting up the networking for this is a somewhat involved process that isn’t too difficult if you have some understanding port forwarding and have a little experience networking computers. Since many people don’t have a firm understanding of this, our technical support department is available for assistance and can even log into a computer with in the DVR’s network in order to help get this set up. In this article we’re going to take a closer look at this amazingly useful feature and how to set it up.

The first step in the process of getting this set up is to make sure that you have your network physically set up correctly. The basic idea is that you want to have a router connected to your modem, then have a computer and your DVR connected to that router. It is very important that you have the DVR and a computer plugged into the exact same router, at least while this is being set up. Once you have the physical set up of the DVR and network configured properly, then it’s time to make a few setting changes in the DVR.

The next step in this process is to go to the computer in order to get some information about your network which will need to be entered in to the DVR so that it’s configured to work in your network. You will need to hit the windows start button and type “cmd” in the field to pull up a command prompt. In older versions of windows you might have to select run from the start menu in order to bring this field up. Once you have the command prompt window open then you’ll need to type “ipconfig” in the command prompt which will return two important pieces of information (as shown in image 1). You will need to make note of the subnet mask and default gateway for this network because you will need to modify the DVR’s network page to reflect them (main menu->setting->network). You’ll also need to make sure that the first three series of numbers in the IP address on the network page of the DVR is the same as the gateway and the last series of numbers in the IP address needs to be unique on your network. In order to make sure that the DVR’s IP address is unique it’s necessary to pull the command prompt up again and type –ping (the IP address that you want to assign to the DVR). Once you are sure that no other device in your network is using it, you can assign that IP address to the DVR (image 2 shows the command prompt response for an IP address that already has been assigned to device). While you’re on the network page you should also change the HTTP port number to 88 and before saving the setting changes you’ve made.

Now that the DVR has been set up correctly for your network, you’ll need to make some setting changes in Internet Explorer before being able to connect to your DVR. You must use IE for this function; other browsers just don’t work with it correctly. Once you have IE open you’ll need to go to tools->internet options->security tab->custom level. Once you have this menu open you’ll need to locate two settings. They are “download signed ActiveX controls” and “download unsigned ActiveX controls”. Both of these settings need to be set to prompt. Then you’ll need to confirm the setting changes. Now are you ready to connect to the DVR.

There are actually three parts to the data that you need to enter into the address bar of Internet Explorer; here’s the formula – http://(IP address):(http port #). For example – The only part of this example that will change is the IP address. If you are on a computer that is in the same network as the DVR then you will use the internal IP address (which is the one that is on the DVR’s network screen). You will need to use the external IP address if you are connecting to the DVR from a computer that’s outside the DVR’s network. We’ll discuss how to find your external IP address later in this article.

Either way once you enter the connection information, you will be prompted with a small ActiveX download. Once the download is complete you will see the log in box for the DVR interface (as shown in image 3). At this point it’s a good idea to hit the compatibility view button to avoid any display problems. It’s also a good idea to make a favorite at this point so that it’ll be easier to get to the log in interface in the future. After that you will be ready to log in to your DVR using the admin account that can be used at the DVR directly.

How to connect your DVR to the internet

There are two ways to view the live footage from your cameras though this interface. The first and easiest way is too simply hit the button marked as ‘open all’ that is located along the left side of this page. The other way to open your cameras is to select a viewing box from the middle portion of this screen and then select a camera from the list on the left to assign the camera that you want to assign to it.
The webservice interface gives you nearly all of the functionality that you would have at the DVR directly. The features that it gives you access to include the ability to view your recorded footage by hitting the ‘search’ button and adjust almost all of the settings that you can if you’re directly at the DVR. This interface also gives you easiest way to extract your recorded footage from your DVR and get it to a computer.

In order to be able to connect to the DVR from outside the network where it’s installed, you will need to get the TCP and HTTP ports open. These ports are shown on the DVR’s network page. Once you have these ports open you should go to This website will let you verify that these ports are unblocked and it will show you the external IP address for that network. This is the address that you will need to use in order to connect to your DVR from a different location. You will need to make the same setting changes in Internet Explorer and use the same connection formula that was outlined previously. As long as you use the external IP address in the connection formula, then you should be able to log in to the DVR at this point from anywhere.
