Setting up your IP camera surveillance system using an NVR with Two Ethernet Ports

Written By:
Monday, September 28th, 2015

The technology behind an IP security camera system is constantly evolving and there have been some nice improvements recently. Here at TechPro Security Products, we offer 3 types of systems including ones using IP cameras to provide the video. Although IP cameras may cost a bit more, they are also going to give you the highest resolution available on the market today. This article is going to explain how to set up this type of security camera system using a very useful configuration because some people are a bit intimidated by the networking involved.

There are several different ways that an IP surveillance camera system can be set up. This article is going to go over the type of set up which uses a NVR with two Ethernet ports. This configuration is great because it can be used to avoid putting an unnecessary bandwidth load on a network. All of the IP cameras that we carry give you megapixel quality video. The data involved in transmitting the video from even a one megapixel camera is fairly significant. If you are working with several of these cameras or ones that provide higher resolution (we now carry up to 12 megapixel cameras!) then transmitting all of that video will use an immense amount of bandwidth. This will cause the most common network to not function correctly. Not only can it cause the camera system to not work correctly, it will probably mean that nothing else will be able to use that network correctly. The solution to this is using the second Ethernet port to keep the data involved with the video transmission separated from the main network.

For the purposes of this article we’ll go over setting up a 64 channel NVR with 64 cameras using the dual Ethernet port method. This set up will require the following equipment.

64 ch NVR
A 64 channel NVR (Model# NVR-ELHS-64-4K-DH)

simple switch
A simple gigabyte switch (Model# Switch-5G)

A 16 channel POE switch. (Model# POE-16MB2GP)

An IP camera. (Model# IPOD-EL3MPIR50)

The first step in this type of setup is putting together a temporary configuration so that you can initialize each camera (see Diagram 1). You will need to have a computer, a POE switch and the NVR (using Ethernet port 1) all connected to the same router. You will also need to make sure that you have the NVR’s Ethernet port 1 configured to work with your network.

IP camera layout 1

This layout will allow you to power each of the cameras and then log into them from the computer in order to get them set up to work with your NVR. The main thing you will need to do while logged into the camera will be to enable motion detection and assign the camera a unique IP address for the IP scheme that will be assigned to the NVR’s second Ethernet port. Changing the camera’s IP address is the last thing that you should do because you will not be able to access it from that computer once this change has been made and saved. There may be some other settings in the camera which will help to customize it for the application which you have planned for it. It’s also a good idea to label each camera with the IP address which you have assigned to it.

Once all of the cameras have been initialized, then they are ready to be set up in their final configuration (see Diagram 2). You will need to go to the network page of the NVR and choose “Multi-Address” from the drop down menu, this will allow each ethernet port to be set to a different IP scheme (for example – Ethernet port 1 can be set up to use the scheme and Ethernet port 2 can be set up to use This is a key feature in keeping the network which is handling the video transmission, from the cameras to the NVR, separate from the main network at the location.

IP camera layout 2

At this point you should have Ethernet port 1 set to match the IP scheme of the main network, which will be used for remote connection. You should also have Ethernet port 2 set to a different IP scheme and all of your cameras set to unique IP address within that scheme (for example – Ethernet port 2 can be set to and each camera would be set to 10.1.1.x, where x is unique to each camera).

The last step is to get each camera assigned to its own channel on the NVR. This is done by assigning the IP address from a camera to the particular channel which you want to associate with that camera’s live video feed and its recorded video footage. This will be accomplished through the ‘Remote’ page of the NVR using one of two different methods depending on the model of camera that you are using (see picture 1).

If the camera is one of our EL models (for example – IPOD-EL3MPIR50) then the NVR will detect it through the ‘Remote’ page of the NVR’s menu system. Clicking on the ‘Device Search’ button will get the NVR to list any network devices which it can detect. Once that you can see that the camera has been detected then all you have to do is put a check mark next to the camera’s IP address and click on the ‘ADD’ button.

If the camera you are using is any other type then you will need to manually add it to the NVR. To do this you will first need to click on the ‘Manual Add’ button. Next, you will need to enter the camera’s IP address, user name, password and the ports that it is using for video transmission.

This type of IP camera system can be customized to suit any sized system. Our sales team can help you get the type of system which best suits your needs. Our tech support team is also available to help you get everything set up and running correctly.


4K and Security Surveillance Design

Written By:
Thursday, September 24th, 2015

Planning your security system whether it is commercial or residential can be a daunting task. How much will it cost? What brand of equipment? What type of camera . . . bullet, dome, PTZ? Do you have existing cable in place and is it Cat 5e rated at 1GB or Cat 6 rated at 10GB (limited to 164 feet)? What kind of storage options will you use . . . hard drives, USB storage, cloud storage, onsite servers, etc. Do you have enough bandwidth available to handle HD and Ultra HD cameras? All valid questions and with High Definition 1080p cameras as well as the fast growing Ultra High Definition 4K products, these become relevant questions when planning your security camera setup. Let’s go ahead and look at 4K more closely, because honestly, that’s the future!

Why 4K . .

4K Security Systems are quickly becoming commonplace as businesses and homeowners are willing to invest a little extra money to reap the benefits of 4K video. I’ve heard excuse after excuse for not buying 4K products with cost being the biggest factor. That, however, is quickly becoming irrelevant as prices continue to drop. 4K cameras and NVRs are priced competitively with 2MP and you can pick up a 40 inch 4K monitor for as little as $500. If you think about it though, monitoring your video in 4K shouldn’t be your ultimate goal. 4K technology can be most useful to those seeking the highest quality video with the most detail. While 4K is available to everyone, there are users who have the potential to benefit the most from the Ultra High Definition of 4K. When securing a potentially high-risk facility such as a Casino, Medical and Retail Marijuana Facilities, Banks, Schools, Hospitals, etc., the ability to zoom seamlessly to capture fine details like tattoos, jewelry, scars and license plates can prove more valuable than your initial cost.

In the past, the ability to digitally zoom in to view high levels of detail has been a problem due to a loss of quality created by pixelization. Consider the fact that 4K cameras can provide four times the evidentiary detail of a 1080p camera! With 4K, you have the ability to zoom in further on an image before experiencing issues with degradation. Up until recently, these critical facilities were using the same 720p and 1080p quality available to everyone. But now, end users can benefit from superior image quality through 4K cameras while not being affected by budget restraints.

Quality and Quantity . .

Now, you know that the quality will be beyond what you ever dreamed of having access to. But, isn’t it going to be considerably more expensive to purchase the same number of cameras? Yes, about double what a similar 2MP/1080p camera would cost. DON’T let that scare you though because you don’t need as many cameras with the 4K products. Take a look at the image below and you can see that images in 4K cover 4 times the area of 1080p. So, take that parking area where you have four analog cameras and replace them with two! You’ll have even more coverage and when you review and zoom in, you’ll be able to see detail like never before.


 So, less cameras. Better images. Same cost. Why wouldn’t you take a look at a 4K security solution?

Better Quality Needs More Bandwidth . .

With better image quality comes the need for more bandwidth.  Let’s use our 8 Channel 4K NVR as an example, the NVR-ELE8M-4K has a maximum of 192 Mbps bandwidth available for recording. That gives you 24 Mbps for each camera. This is where things would get challenging for use of 4K for security since 4K is four times 1080p or 3840×2140. Since many end-users need security applications to be “real time” or close to 30fps, the total bandwidth required for a single 4K camera would be 373 Mbps. That would be an impossible number for a network to handle, but when you apply the current standard compression method of H.264 (generally 50:1) 4K bandwidth is reduced to 8Mbps per camera. Using the H.264 compression, that’s more than enough to deliver 4K at real-time 30 frames per second.  Fortunately, manufacturers realize the strain that multiple high bandwidth cameras have the potential to put on a network. They are quickly working to introduce new compression standards such as H.265 HVEC that will almost half that current compression technology! Still, at current capabilities of most networks running Cat6. Cat5E and even short Cat5 runs, you should have plenty of bandwidth to meet your needs. Consider the user who’s running 4K cameras at 30 fps and figure that they can operate the cameras at about 8Mbps without causing any lag on the network or their workstation.

The Need for More Storage  . .

You would think that your increase in bandwidth would drastically increase your need for storage and increase storage costs at the same time. Not necessarily true! You have multiple ways to either reduce your need or increase your storage space inexpensively.  Until H.265 compression is more widely adopted, you can do some things to reduce the need for additional storage space. One way to do this is to reduce your frames per second (fps) rate. The most direct way to reduce storage is to use a lower bit rate stream for each camera with lower frame rates or you can set it to record only when motion occurs. This can dramatically reduce the amount of storage space used or needed. There are also tons of inexpensive storage options since companies like Western Digital and Seagate are offering personal cloud solutions that give you Network Attached Storage starting as low as $250.00 for 5TB of storage.

What Are You Waiting For  . .

If you’re new to security camera surveillance or if you are testing the waters in regards to IP cameras, you should consider our 4K NVR’s and 4K Cameras. I know from experience that it can be frustrating trying to keep up with constant changes in technology but I am confident that 4K is going to be around for quite some time to come. It’s time to make that move out of analog and into IP and if you’re going to do it . . . you might as well do it right!

A Guide On Product Series and Product Technology

On you may have noticed the following logos in relation to our products. Well, excitingly enough, they are here to help as we grow. Elite and Techpro series products have been a staple to our product line up for quite some time now. As technology advances, the industry changes and customer demand increases we have add to modify our line up and this fall of 2015 we are happy to be introducing our new prime series to our product line up.

elite-cvi prime-TVI TP-CVI
elite-ip-network prime-ip-network TP-TVI
elite-series prime-SERIES TP-IP-Network

These product series labels were created to help you, the user, understand our product lineup and product compatibility features. Each Series is equal in quality, but the difference is in software and compatibility between products.

Shopping guideline

Step 1: Start with Technology

Under each series title you will notice the type of technology associated with it.



This is Important because not every product inside a series will be compatible. For example, an Elite Series Network Video Recorder (NVR) will NOT be compatible with Elite HD-CVI or Analog cameras and HD-TVI Cameras will not be Compatible with HD-CVI DVRs.

Just Because they are the same Series does not always mean they will coincide. Their Technology compatibility must be able to match up as well. Network Video Recorders must be paired with IP Network Cameras and HD-CVI DVRs Must be paired with HD-CVI or Analog Cameras. So along with each Series of device (Recorder or camera) be aware of each technology associated with it.

Technology Compatibility Breakdown:

HD-CVI Tribrid DVRs: Compatible with HD-CVI Cameras and Analog Cameras

HD-TVI Tribrid DVRs: Compatible with TVI Cameras and Analog Cameras

IP Network NVRs: Compatible with IP Network Cameras.

Note: if the NVR is ONVIF compatible the device has the ability to sense and search for any ONVIF IP Network Camera as long as both the devices, recorder and the camera, have ONVIF.

Technology Overview

What is HD-CVI? High Definition Composite Video Interface: This technology was developed by ZheJiang Dauha Technology Co.  Dauha made the technology open access in July of 2014 allowing other manufactures to utilize the technology and improve upon the chipset. The name has to do with its baseband and quadrature amplitude modulation technology which is able to avoid CVBS cross talk, completely separate the brightness and hue signal, and further enhances video quality.

What is HD-TVI? High Definition Transport Interface: It is a DSP-TVI technology developed by Techpoint in 2012. The chipset was sold and is now also open access allowing other manufactures to utilize and develop the technology. HDTVI technology can be implemented in an existing setup over coax  and produces reliable HD video signal transmissions over a single coaxial cable.

Both HD-CVI and HD-TVI are affordable HD over Coaxial cable solutions. The HD-CVI and HD-TVI chip sets have similar features and both can provide analog high definition solutions

Coax. Transmission Distance 1000 – 1500 feet 1000 – 1500 feet
Cat5 Transmission Distance 700 feet 329 feet
720p Supported Features (FPS) 25, 30, 50, 60 25, 30, 50, 60
1080p Supported Features (FPS) 25, 30 25, 30
DVR Features 720p & 1080p Signal Simultaneous Choose 720p signal or 1080p Signal. One or the Other


IP Network Technology Overview: IP Network Surveillance Systems provide the highest resolutions along with the most adaptable infrastructure. Our current product lineup includes cameras and NVRs that have resolutions from 2MP to 12MP (4K). IP Systems offer a few benefits over traditional CCTV, HD-TVI and HD-CVI. IP (Internet protocol) network surveillance systems have improved search and storage features as well as a more flexible infrastructure.

Step 2: Review of the product series


The Elite Series has been our staple series on up to this point. This series is primarily HD-CVI and IP Network Technology. The DVRs, NVRs and IP Network Cameras utilize the SmartPSS Software in this series. Elite Cameras work best with Elite NVRs and DVRs. NVRs that are ONVIF compatible will work with ONVIF Compatible cameras.


The Prime Series is new to the’s product line up. This Series is not an inferior series compared to the Elite Series. The Prime series simply offers features and software that are different from that of Elite series. The Prime series is primarily composed of HD-TVI Technology and IP Network Technology. It also has ONVIF compatible NVRs.

In best practice and for seamless integration we do recommend pairing Prime Cameras with Prime Recorders and Elite Cameras with Elite Recorders. Just remember to compose your set up with the appropriate technology.


The Techpro Series of Cameras have also been a part of for quite some time. The TechPro Series of cameras are openly compatible with the Recorders on the website. Simply utilize the appropriate technology when pairing these cameras with Prime or Elite recorders.

How do I know what camera series is compatible with my Recorder?

Under the Description Tab of each NVR or DVR product page. If you have questions regarding what cameras to choose we will gladly display the type of cameras that are compatible. See example image below.


We also offer a number of multi-technology solutions with Tribrid and hybrid recorders and with you receive flexible and affordable options.

Tribrids allow up to three technologies. As an example, most of the Elite Tribrids allow for all channels analog, all channels HD-CVI with up to two channels IP. Some Tribrids offer all channels for all three technologies. These recorders are designed primarily for Analog users looking for an affordable upgrade from analog. Pick a tribrid recorder and slowly upgrade to HD cameras as your budget allows. Just make sure to check under the description tab for a quick reference you your series and technology compatibility.

Understanding IP Cameras and ONVIF Compatibility

When choosing to use IP network cameras for your residential or commercial security camera system there are a few things to take into account. This article will focus on clearing up some common questions regarding Network IP Cameras and NVRs (Network Video Recorders). In order to clarify some of the topics covered, I will often refer to “Techpro Security Products” brand of NVRs and cameras.

A square peg forced into a round hole. 3D render with HDRI lighting and raytraced textures.

Analog Cameras & DVRs
First, it is important to understand some differences between IP cameras and analog cameras. In most cases, an analog camera simply sends the video signal back to the DVR over a coax cable. The DVR is where the encoding and recording is done. It also contains the software for managing the camera settings and camera options. You can access and modify each camera’s settings through the DVR itself. The DVR also provides the ability to view the cameras in real-time and review recorded footage. Without a DVR you would not be able to record or view recorded video.  Essentially the DVR is the brains of an analog security system. Usually, analog cameras are powered with a 12 or 24 volt power source.

IP Cameras
Network IP cameras, on the other hand, are standalone units that can be accessed via the camera IP address. All of the software and settings (the brains) are embedded in the camera itself. Many IP cameras also have an SD card for storing recorded video. IP cameras are just like any other computer or smart device that is accessible on your network. IP cameras use CAT5 or CAT6 to transfer the video, and in most cases can be powered over the same cable when use in conjunction with a POE (Power Over Ethernet) switch.

Essentially this means that you can have 1 IP camera on your network or several if you choose. Each IP camera would have its own user interface and specific settings that can be viewed or managed individually by going to the IP address of each camera and logging in to it.


Viewing Multiple IP Cameras Simultaneously
As you might guess, if you have multiple IP cameras, it quickly becomes a hassle to have to go to different IP addresses and log into each camera individually in order to view in real-time or re-view recorded video.

So, what do you need to view all of your IP cameras in one place? The answer is an NVR (Network Video Recorder). You can think of an NVR as a hub with a single IP where you can view all of your cameras simultaneously. The NVR can also house a hard drive(s) to store the recordings of all your IP cameras and dramatically increase your storage capacity.

IP camera compatibility
Because each IP camera has its own user interface and camera options built into the camera itself, not all IP cameras are completely compatible with all NVRs. Next I will talk about the various IP camera compatibility options.

Compatible Network IP cameras and NVRs
Your best option is to buy network IP cameras that have a compatible NVR. This means that the manufacturer of the cameras specifically designed the NVR to be compatible with the user interface, software, and options that are embedded in the camera itself.

For purposes of this example we will talk about the “ELITE” line and “PRIME network IP lines by Techpro Security Products. If you were to buy Elite IP cameras along with an Elite NVR, you can expect that the cameras will work seamlessly with the NVR. This means that all of the camera options and functionality are directly accessible and configurable through the NVR itself. There is no need to log into each camera individually for the initial setup or to access the camera’s functionality thereafter.

The same can be said for the PRIME IP line. If you were to buy Prime IP cameras with a Prime NVR you are guaranteed to have full functionality directly through the NVR.  Buying IP cameras that are fully compatible with the NVR can make for a fast and convenient setup as well as streamline the maintenance and usability of your new security camera system.


The ONVIF Protocol
What if you already have IP cameras and just want to replace your NVR or vice versa, you have an NVR but you want to add new IP cameras?

All cameras use a specific protocol for communication between the NVR and the camera itself. One of the most common protocols is ONVIF. In most cases, if the camera is ONVIF compatible it will be able to communicate with an NVR that is also ONVIF compatible. This means that you are guaranteed to get video output from each camera to the NVR. But in many cases, not all of the cameras functionality will be available directly through the NVR.

TechPro Security Products also has a TP line of IP network cameras. The TP line uses the ONVIF protocol and can be used in conjunction with the Elite NVRs, Prime NVRs or any ONVIF compatible recorder.

When using ONVIF, it is recommended that you log into each camera individually to configure the settings at the camera level prior to installing or mounting it.  Once all of your cameras are configured the way you like, you are ready to install them and video will be transferred back to the ONVIF compatible NVR.

Some common things you will want to set up on your ONVIF cameras include but are not limited to the following:

The Camera IP address – If the cameras you are using do not have a DHCP option you will want to manually assign each camera a unique IP address to avoid IP conflicts on your network.

Main Stream Resolution
Extra Stream Resolution
Date & Time Format
Camera Label
Motion Detection
Motion Masking
Color and Contrast settings
IR Configurations

It is also recommended that you update the camera firmware at the time of setup as it may not be able to be updated through the NVR.


TVI vs. CVI, What is the Difference?

Written By:

When it comes to the “New” HD over coaxial market, there are a couple, some say a few, choices on the market.  The 2 major players in the HD over coaxial market are HDTVI (High Definition Transport Video Interface)  and HD-CVI (High Definition Coaxial Video Interface).  There is a third lesser known technology, simply called AHD or analog High Definition.  Now you are probably sitting there saying to yourself, WTF is the difference between these technologies and which one is for me.  I will try to hopefully help give you some differences and benefits of the technologies

HDTVI (High Definition Transport Video Interface) and HDCVI (High Definition Composite Video Interface)

HD-TVI technology was created by a company called Techpoint in 2012 and backed by Hikvision around the same time.  This was created by a third party company to compete with a technology coming out from the factory Dahua, who was about to release HDCVI.  There have been rumors out there that someone planted spies inside of Dahua that learned what was coming and once pulled out they created the company called Techpoint.  But, I don’t think any of it will ever be confirmed.  Hikvision is the world’s largest surveillance manufacturer and backed by the Chinese Government and has backed Techpoint in this endeavor. It has brought us one of the biggest revolutions to the CCTV (closed circuit television) market since the creation of IP, internet protocol, cameras.

HDTVI like HDCVI both come from the same principles created by the TV industry with the government back mandate for a Higher Definition video transmission of all broadcasting.  This spawned a surveillance type known as HD-SDI.  In essence, SDI had major limitations with regards to the distance it could be transmitted.  This limitation was eradicated with the creation of the two new technologies.  HDTVI is able to send 1080p video approximately one thousand feet, whereas HDCVI can transmit 720p video upwards of sixteen hundred feet and 1080p video around the same distance (or as quoted by Dahua – three hundred meters). There are some other similarities and then again a few differences.  I will go into and touch on the important, or better yet, more necessary information to know so you can have a better understanding of the two technologies.

With HDTVI recorders, all of them from their simple units up to their largest unit are capable of handling analog cameras, HDTVI cameras, Hikvision IP cameras and Prime IP/HDTVI cameras.  Whereas HDCVI recorders from the base model all the way up to 16 channel recorders (also known as Tribrid DVRs) can also handle analog cameras, HDCVI cameras, Dahua IP cameras, ONVIF IP cameras, Prime IP/HDCVI cameras and Elite IP/HDCVI cameras.  As you can see, both of the technologies recorders can handle three different technologies in one recorder making them Tribrid DVR’s.  There are Tribrid recorders that can only handle their specific technology as well as the two other technologies.  The major difference between the two technologies recorders are the Dahua recorders can also handle other brands IP cameras and the Hikvision TVI recorders can only handle Hikvision IP cameras.

Now both companies offer some basic camera models to go along with their technologies.  For example, you can get a fixed or varifocal lens dome or bullet option from both platforms as well as a Pan Tilt Zoom.  With HDTVI, there has been a slower development of a variety of camera models available from the major player.  Dahua has a very wide product line available and backed by the factory.  Now, both technologies have had third party companies that have stepped up to provide the wide variety of product lines that the factories have neglected.  I personally like the standard housings from both factories, but am also a huge fan of some of the third party product offerings as they typically have a wider variety of colors and mounting options that the big boys have neglected to adopt.

I have always been a fan of third party cameras and typically find that you will get more options for a lower price point than you find from the major players.  Now the major players will typically have stronger warranties than the smaller factories, but bang for buck the smaller factories give you a damn good product.  I personally like the Techpro Series cameras for both HDCVI and HDTVI for the options that they offer and some of the form factors are more appealing in my opinion.  I have had and installed many of systems over the years, as I was an installer and integrator for several of years before coming on board.  I have found these newer technologies are as simple to use as the original Closed Circuit Television systems, with the major advantage of much higher definition and quality.


As you can see, there really is not much of a difference between these two types of technologies, outside of the major players in the industry backing them.  I have personally used both of their interfaces, applications for mobile devices, and CMS software and find them on a fairly level playing field.  Some of the major differences between them come in the Graphical User Interface or GUI for short.  For a first time user, they are both rather easy to get through, allthough I believe HDCVI has a slightly easier to use interface for the novice in the surveillance world.  The reason is that the interface has a better simpler layout than you find in the HDTVI system.  HDTVI has things nestled under different tabs, very similar to what HDCVI did in the beginning until the addition of the “Blue” user interface experience.    I guess the bottom line on this is… if you are starting from scratch either system will work for you, or if you are doing an upgrade from an existing analog system either will work.  Now if you have used Techpro Security Products DVRs in the past you would want to stick with the Elite line, but if you are starting new, the Prime line would be a good place to look at as it is a very nice and solid platform and generally a little less money.
