Benefits of an NVR with a Built-in POE Switch

Written By:
Monday, August 17th, 2015

Many of our customers call us to ask why they cannot change the camera’s position when using a built-in POE NVR. The short answer to that is that it is not possible after the cameras are connected for the first time on the NVR. See, the NVR’s POE built-in switch is a separate entity. The idea behind this technology is to offer security, avoid broadcast storm, and in theory separate the traffic from the IP cameras and NVR completely. Also, the most obvious reason to use a built-in POE on these NVRs is to power the cameras from one unit, without using an external POE switch. This will reduce the cost of equipment in theory.

So, why can I not move the cameras to a different position after I plug them in the NVR? Well, the reason is that the MAC Address of the cameras “Sticks” to the port the camera is connected to, and the NVR will not release that unless the NVR gets defaulted completely.

What can I do if I want to change the position of my cameras then?

Ahh, that’s why I’m writing this article, to show you an idea I have that I think could help many customers that are frustrated with this type of setup.

NOTE: Although this article is solely to show a temporary fix to the way the POE works, it is intended to be used ONLY on those NVRs with POE built in. In the near future, a firmware will “fix” or add a different way to accomplish the following task. Any camera added to the built-in POE switch will not be accessible over the LAN interface. Instead, if you would like to access the settings of the cameras, you will then use the NVR’s web interface (EL SERIES IPC ONLY). For ONVIF cameras, you will need to be connected with a computer to one of the ports of the built-in POE Switch and either assign a static IP on your PC Ethernet card or simply get an IP address from the POE switch IP pool. You will then be able to change any settings on the camera.

The Following list will show you the NVR models numbers with Built-in POE:




Lets begin by understand the settings on the NVR. The POE switch, like I said before, is a separate entity from the regular single LAN port. Normally the single Ethernet port of the DVR IP address is The POE side is by default You can change this by going to the network settings. For this article I will be using the web service interface of the NVR. Click on Setup, from the left options, click on Network then all the way to the bottom click on Switch.

POE Switch

Notice that the IP address and default gateway are in the same range, in fact they are the same number. If you planned to change this then you must have the same number on both the IP address and gateway. Also, the IP address here and for the NVR cannot be on the same range. An example is if the LAN port is configured 192.168.1.X where X is a random number from 1-255 then the IP address from the switch side cannot be on that range. You can leave the defaults as is and you will not have any conflict, or if you want to change it to something similar then you can use something like 192.168.x.x where the (x.x) can be any number different from your LAN IP Address.

The next step is to make sure you configure the essential settings for your NVR. Time, Date and DST are essential settings to keep your cameras in sync with the NVR time and to make sure the recordings have the accurate date and time in case an event happens.

Go to Setup>Setting>General and Date&Time. Adjust the date format and time format based on your liking.

Time Format

System Time

Go ahead now and connect the cameras to the POE switch of the NVR. For this demonstration I have 2 cameras connected with a short CAT5e cable. Allow about a minute for the cameras to show up on the screen of the NVR. NOTE: If for some reason the cameras do not come up on the screen, there is a chance that the IP cameras’ IP addresses are set to static and the NVR does not know how to change it to dynamic. Simply disconnect the camera and put it on a external POE switch and change the address using the config tool. You can download the tool here: CONFIG TOOL 2.0.

Assuming that all the cameras are set to dynamic, you should start to see the video streaming in the NVR. Also notice that you can tell when a camera is added automatically to the NVR by checking the LAN Icon displayed in the top left corner. This indicates that the camera is detected for that channel.


I have a total of 4 cameras connected on this NVR. Two of these are connected directly to the unit and two are brought from the network. The next thing to do will be creating a tour that will basically rearrange the cameras the way you want it. Ideally it will be easy for you to make a note of the IP cameras’ channel and what channel you want them to appear. For example, if camera 1 and 3 are not on the channels you want, then all you need to do is create the tour and select the cameras in the order you want them in the tour screen. If you want camera 3 on channel 1 then click on channel 3 first, that indicates the tour that the fist camera in the group will be #3. For this example I will choose camera 3 to go on window 1, camera 4 on window 2, camera 1 on window 4, and lastly camera 2 on window 3.

Below is a picture what it looks like before enabling the tour:


To configure the tour, login to the NVR and click on setup>settings>Display>Tour.


Notice that the NVR has different views (Window Split). On this NVR (4CH NVR ELT) I only have View 1 or View 4. For this trick to work, you will need to uncheck all of the channels on the View 1 channel group. This will ensure that the tour will only display a 4 View Split. From the window split drop down select View 4.


Now in this window, delete the current view of cameras then click on the Green + button to add your own. Like I said before I will click on cameras 3, 4, 2 and 1 to add the view on my screen.


Click on Enable and click on Save. Now this is how my cameras are arranged at this point. NOTE: Due to the nature of the Tour, the screen will refresh every 5 seconds. You will see that the screen goes dark and comes back for a second. I will recommend you to set it to 120 sec so you don’t see the refresh of the screen often.


DISCLAIMER: The purpose of the tour is to arrange the cameras on the main screen. The arrangement of the cameras will not be displayed when viewing the cameras over the web service. Also, in the event of searching for footage, the camera arrangement will not be paired to the channel in the footage. An example of this is if camera #4 was showing originally on channel 1 prior to enabling the tour, then when searching footage for that camera you will need to select channel 1 since that is the original window of the camera in question.


Cloud Surveillance: Video Recording Backup for IP Cameras

 Cloud Surveillance Video Recording Backup for IP CamerasThe sole function of any surveillance system is the ability to capture and retain footage of the events that take place. Imagine all the times there never existed an instance to justify or the need for footage confirmation. Then the day comes when an occurrence takes place and you retreat back to your DVR to retrieve and review the footage. Imagine how insulting the feeling is to discover it wasn’t there. Weather your storage space was inadequate, a hard drive failed or a smart crook covered his tracks and took your recording device; this realization is nothing short of grim.

With all the safeguards and measurements we take to guard and protect ourselves and property, what extent have you’ve taken to create a fail safe? A Plan B if you will, when your first endeavor of security measures fail. Some DVR and cameras have optional recording capabilities. Let’s take a look at this back up options.

As we explore optional recording capabilities lets first take a look at cameras with built in memory card slots. Just like our newer phones, camcorders, and photo cameras use a removable memory card known as SDcards (or micro SD version). Select security cameras are integrated with a slot for the placement and extraction of this card. Here you can choose to save additional footage along with your DVR. So in the implication of an event, if one device recorder feature failed to retain footage (or was stolen or damaged) the camera would have the events saved on the SDcard.

DVR/NVR recorders saturate the market. From electronic stores, hobby shops, consumer markets and the World Wide Web. So where do you even start to delegate on a recorder for you? Figuring out the recording quality is a great start. Pay attention to the listings of recording resolutions and frame rate against all available channels. Any DVR not capable of providing a recorded value of 704×480 at a 15FPS or higher shouldn’t be included on your list, so scrap all those other possible contenders who don’t. Another great quality is the features the recorder offers. How many HDD drives can it hold? Is it remote access capable and are there diverse recording options available? Recorders that offer FTP uploads, emails with snapshots, or push notifications alerting you of events are valuable features adding to your Plan B presidence. Additional advantages like eSata ports to attach additional storage or the ability to set a raid configuration are outstanding backup options. Taking the extra effort and utilizing these innovative options can prove to save you from a dumb founding moment. There may exist another solution still as we explore:


 Cloud Surveillance Video Recording Backup for IP CamerasCloud Services

Cloud sharing is the terminology for anything data related, being uploaded or downloaded on virtual hosting services. From Microsoft, Apple, and Amazon to free-lance competitors like Drop Box, it seems these remote database services have sprung up overnight. The concept is actually more common then you realize. Have you ever visited a website (of course you have, what am I saying) or had one hosted?  Do you own an email account? These are all forms of virtual storage of our own personal data on someone else’s servers made accessible from anywhere and/or anyone you authorize. This essence fits the profile of a cloud service.


 Cloud Surveillance Video Recording Backup for IP CamerasGet your head out of the clouds

This is one idiom I’ll reframe from using as we learn the infrastructure of cloud computing. The term cloud computing derives from the cloud symbol that’s often used to represent the Internet in flowcharts and picture diagrams. These services are broadly divided into three categories:



  • PaaS (Platform-as-a-Service): This type of cloud service is defined as a set of software and product development tools hosted on the provider’s infrastructure. Developers create applications on the provider’s platform over the Internet. PaaS providers may use APIs, website portals or gateway software installed on the customer’s computer. Like, (a subsidiary of and Google Apps are examples of PaaS. Developers need to realize that currently there are no standards for data portability in the cloud. Some cloud service providers will not allow software created by their customers to be moved off their (provider’s) platform.
  • SaaS (Software-as-a-Service): In this cloud model, a vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end interface (like NetFlix). SaaS is a very broad market with services ranging from anything like:
    • Web-based email
    • Inventory control
    • Database processing
    • Website Hosting
    • Batch Uploads & Downloads

… and because the service provider hosts both the application and the data, the end user is free to use the service from anywhere, as long as they have internet of course.

  • IaaS (Infrastructure-as-a-Service):  Is the type of cloud that provides the ability to start, stop, and access/configure their virtual servers and storage. In this tier, cloud computing allows a company to pay for only as much capacity as desired and expand as needs require. This “pay-for-what-you-use” model resembles the way we use electricity and water consumption.

A popular company, NetFlix, utilizes an Iaas cloud service called AWS by Amazon. A hosting service available to many. Through this type of cloud service they are able to create a program and store a library of media, based on what they use. When they add more to their movie repertoire they retain more storage space without ever having to invest capital cost into their own: Location, Servers, Computers, Data storage drives, etc., all the while receiving Amazons customer support and guarantee. A great business model, wouldn’t you think?

A cloud can be private sector or public usage. A public cloud sells their services to anyone on the Internet. A private cloud is a proprietary network or data center that supplies hosted services to a limited number of people. When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud (example NetFlix). Private or public, the goal of cloud computing is to provide easy, scalable access for computing resources and IT services.

 Cloud Surveillance Video Recording Backup for IP CamerasCan a cloud service be used for your surveillance         

Yes, any file can be uploaded onto a cloud service. Either by a built-in feature like a FTP or a program, you can direct your footage to upload to a file that’s synched with the cloud application of whatever provider you use. Be sure to check the available amount of storage you’ll receive and the limitations, if any, a cloud service provider may have or restrict.


Netflix is a SaaS Cloud model to us

The overnight success of Netflix never happened but their online streaming business strategy did. CEO Reed Hastings, scorned with embarrassment of an overzealous rental store charging him a $40 late fee for a VHS copy of Apollo 13, came up with his company idea Netflix. In 1997 he mailed a few CDs in an envelope to himself. A very much anticipated 24hrs later he received his first test subjects. He ripped open the envelopes to find the CDs in great shape, thus the birth of movie-by-snail mail distributor Netflix. In the end year of 2007 and beginning of 2008 Netflix launched its online streaming feature. Joined by deals for multi-platform apps with Xbox, PS3, smart devices and Wii not only made it convenient to entice their services through convenience but also making aware their presence of goods to an unreached market as-of-yet. The popular video-streaming commands an estimated one-third of all internet traffic during peak traffic hours. Besides accomplishing this feat of web traffic, Netflix is also unarguably the largest pure cloud service.

I hope this has been enlightening not only in the sense of what a cloud is but also how it works. A simple technique to remember is pretend this service is a big hard drive somewhere off-site of your location. You have complete access to this data through any computer/smart device of your choosing that has internet access. No brief case to carry or external hard drive to lug around on your travels. Now some may feel uneasy storing and immense amount of personal and intimate data on these cloud servers. I myself being one of them. The future of personally owned hard drives is not going to die out either but there are some useful advantages. So with some discern and precautions, I do use a cloud service myself and teach consumers on the convenient possibilities of them as well. So if you’re looking for that extra pre-caution to preserve your data or a safety net for backing up your security camera system footage I say full sails ahead. In the meantime, stay awesome guys.
