NAT and Port Forwarding

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!

SecurityCameraKing is the Amendment 64 Security Camera Authority

Written By:
Tuesday, April 14th, 2015

Amendment64SCK-Seal
We here at SecurityCameraKing.com want to ensure you that when it comes to the needs of your surveillance equipment inspections for the Colorado Cannabis Community SecurityCameraKing is the Amendment 64 Security Camera Authority. We have carefully gone over Article XVIII, Section 16, otherwise known as “Amendment 64” and we have helped numerous Marijuana Retail Shops and growers with their security camera requirements. The following is a reference of what you need to be compliant as well as additional information you might need.

The following is a reference of what you need to be compliant as well as additional information you might need.

Analog or High Definition Cameras

While there are no stated minimum requirements for your security camera system needed for your Marijuana Retail establishment, we wanted to show you the difference between what an analog camera will provide versus a High Definition Security Camera. Both formats will get your inspection passed. Both can record on to a security recorder and can be viewed anywhere in the world you have Internet. Both will potentially deter criminals just for the reason that they will see the cameras and go on to the next store.

However, if you do ever have criminal activity, you would want to be sure you have the best recording possible. The difference is in the detail the camera will capture. The video from an analog camera will distort, or pixelate, when trying to zoom in and see detail. Click on the link below for a side by side video comparison.

https://www.youtube.com/embed/zgxDzKTvnVE?rel=0 
 

Imagine if someone broke into your store and you presented your security camera footage to the authorities. Having High Definition Secuirty Cameras could mean the difference between an arrest, due to a positive ID, versus not being able to see any detail. This is why we suggest going with High Definition Secuirty cameras such as HD-CVI or IP. Sure, you could get along with Analog to get your inspection passed, but in the long run, just how much is your Marijuana investment worth. Besides outside theft, you need to keep an eye on your employees as well as your crops. HD Security Cameras can also be used to monitor the healthiness of your crops (if you are a grower).

40 Days of 24/7 Security Recording

By law, you are required to have a surveillance system that can record and hold 40 days of security footage recording 24 hours per day non-stop. In order to figure out how much disc space you need for your security camera system, we have created an Online Hard Drive Calculator to help you determine that. Below are two examples of how much disc space you would need for 16 cameras. One of the major differences between an Analog Security Camera System and a High Definition Security Camera System, besides the clarity of the video, is how much disc space is needed to hold information for the 40 days.

Hard Drive Space for Analog
Hard Drive Example for an Analog System
Hard Drive Space for High Definition
Hard Drive Example for a 2MP High Definition System
As you can see it is very important to determine how much hard drive memory you need before you make your purchase so you can prove that your security camera system can record footage for 40 days. It is always a good idea to get more than you need to be sure.

Creating a Site Plan

It is very important to develop a site plan for your Marijuana Store in Colorado or for your Marijuana Growing Facility. This way, we can help you determine exactly where your security cameras should be placed. All entrances and exits, sales areas, growing areas, windows, storage areas, etc. need to have 24/7 camera surveillance, and we are experts when it comes to placement and coverage. All you need to do is provide us with a layout (whether it is professionally done or just scratched out on a piece of paper), and we will assist you with what you need to get you surveillance system inspection passed. Having the cameras configured in the site plan will also make it easy for your installation process. If you do not have an installer and do not want to do the installation yourself, we can recommend one. If you are in the Denver area, we can take care of the installation through our install department.

The image below represents a typical site plan. This is not an actual plan as we do not make public our customer’s facilities. This is just an example, and chances are your site plan will be very different.

Introducing The Tribrid DVR (HD-CVI, IP, and CCTV all in one unit!)

Written By:
Friday, August 29th, 2014

Tribrid DVR - HDCVI IP and CCTV in one unit

This is the supreme standalone upgrade solution. If you’re looking to keep up with new SecurityCameraKing.com technology then this Tribrid DVR is your answer. If you have installed previous analog systems and you have great cameras and beautiful cables and power supplies in place and you have upgraded all of your hard drives, replaced network routers and switches but you still have your old school analog DVR that is ready to retire. Well guess what? You can keep your good analog cameras, power supplies, hard drives and network hardware. All you need is the new Tribrid DVR using analog, HDCVI, and IP camera technology. You can now show off your new Tribrid to your friends, family and business associates by incorporating new HDCVI technology and IP megapixel cameras. If you’re looking to add more cameras or just want to replace exciting cameras with higher resolution units then the Tribrid will do the job. Setting up the unit is a breeze, I will illustrate some simple setups, new functions and configuration for the new TRIDVR-EL16.

Connecting HDCVI, Analog and IP cameras to the Tribrid

Connecting cameras to the TRIDVR-EL16 can get tricky but SecurityCameraKing.com has 5 star tech support that will help you the whole way (for free), but if you’re one of those do it yourselfers, then here are some simple to follow set up instructions. First, logging in to the system is the same as all of our DVR, NVR, and Hybrid systems. The default user name is admin and the password is admin. After logging in you will encounter the wizard you can just exit out of. From the main menu go to Camera.

Tribrid DVR Menu1

In the image page you will see the channel selection (Drop down box). You can configure each COMPATIBLE cameras saturation, brightness, contrast and sharpness, just remember to save after every modification.

Next is the Encode page were you configure your Compression, Resolution, Frame Rate, Bit Rate, Audio and sub stream per COMPATIBLE camera.

Tribrid DVR Menu2

Next in line is the Cam Name. Here is where you name your camera channels. It is a brilliant idea adding a name to a channel/camera, you automatically know who, when and where the even occurred. Example front door, back door, bedroom or backyard on February 3 2014 at 7:30pm.

Tribrid DVR Menu 3

Now the very important part, the Channel Type page. Here is where it can get a little tricky. The Tribrid’s BNC inputs are defaulted using HDCVI cameras. The adjustment is simple just switch the channel you have the analog camera connected and enable the analog field.

Tribrid DVR Menu4

Tribrid DVR Menu5

When connecting and configuring an IP camera you have to start from the last channel of the Tribrid. For example if you have a 16 channel Tribrid DVR then you would start adding cameras from channel 16 and down, so the first IP camera you connect and configure will be channel 16. You would copy the same configuration as the HDCVI described previously and still be in the channel type page and then towards the bottom of the page there is an arrow selecting next page. Go to page 2 and select IP on channel 16 for your first IP camera, 15 would be the 2nd IP camera and so on. Remember if you have any question or concerns you can always contact TechPro Security Support Monday through Friday from 9am to 6pm Eastern Sunny Florida time.

Tribrid DVR Hardware.

The motherboard is strong and smart and you can install up to eight 7200 RPM SV-35 3TB Hard Drives capturing proper resolution and long length recording with no hassle. On the back of the unit you have HDMI, BNC, VGA, Audio, RJ-45, Alarm, PTZ control, USB and e-sata inputs as well as other outputs.

DVR Tribrid System Connection

Tribrid DVR Remote view configuration.

Network configuration is the same as all of our Security Camera King recording units. TCP/IP must match your network, the TCP port should be defaulted at 37777 and the HTTP port should be changed to 88 (the TCP and HTTP ports has to be forwarded in the router to have external access).

Tribrid DVR Menu6

             

Tribrid DVR Menu7

Email alerts can be configured here under the same network sub-menu, utilizing motion or alarm detection to send push emails to your mobile device alerting you who or what has infiltrated your space.

Tribrid DVR Menu8

Tribrid DVR Motion detect recording or 24/7 recording.

The setup is the same as all of our other recording units, go to storage and configure the Schedule, HDD Management, advance and record as you would like normal. If you need more assistant on the setup please feel free to contact a SecurityCameraKing.com Technician.

Coming soon – New P2P 2D bar code App scanner

When trying to connect to your security camera system it is difficult and it involves configuring sophisticated network settings so you can view your family and business via your Phone, Tablet or any computer in the world that has Internet access. This new and upcoming feature will make life much easy when configuring remote external access. REMEMBER Coming Soon!

Tribrid DVR Menu13

Tribrid DVR System Settings

The general page is where you need to configure your Device ID and number, language, Video Standard, HDD Full option, Pack duration, Real Time Play, Auto logout and mouse speed. You want to make sure you adjust your date and time to your timezone because if you need time and date stamp file for evidence it needs to be correct.

Tribrid DVR Menu14

The PTZ page is very important when installing an analog, CVI or IP PTZ, the configuration just needs to match the PTZ camera.

Tribrid DVR Menu15

The account page is where you give privileges to users. Assigning accounts are easy with the new interface, make sure not to delete your technician’s administrative password because when you need support, the fastest way in to fix the issue is logging in as an administrator (so don’t forget the admin password).

Tribrid DVR Menu15

In conclusion in my experience, this unit blows away any other upgrade. WHY? Because you get the best of three worlds. You can upgrade your whole system and have indoor/outdoor HDCVI cameras and Smart Auto Tracker IP cameras in your warehouse or retail store while still keeping your existing analog cameras you don’t want to discard. One small step for analog, a giant leap for HDCVI and IP technology.

Here is a short unboxing video of the Tribrid DVR (TRIDVR-EL16)

DVR Viewer Software

Written By:
Tuesday, April 15th, 2014

1254442_original

The world has changed a lot in the past few years, thanks in no small part to the digital revolution, including great advances in the Internet, networking, security camera systems, DVR viewer surveillance software, and personal computers. Possibly nothing has changed more than the business world, which has countless new tools at its disposal to not only help the company make money, but keep its merchandise and employees safer. Through the advent of network enabled digital video recorders (DVRs), DVR viewer software and high speed internet connections, it is now possible for a businesses to monitor their stores and warehouses remotely from anywhere in the world as long as they have a high speed internet connection.

This makes many different things possible for a company when they are monitoring their business, and for this article, we will focus on employee safety. Employee safety is critical to the operation of a business because if the employees do not feel safe, they will not want to work for you. While our world does appear to be getting safer with record low crime statistics, armed robberies do still take place and it is up to you as the owner of a business to ensure that your employees are safe in the event of one.

One of the best ways to do this is by installing a video surveillance system with remote viewer capability so that someone can monitor your business remotely over the Internet. This means that if you have employees working late into the night, in a bad neighborhood, you can be at home watching that they are safe. You can also hire a company to monitor your security cameras for you. This is the equivalent of having a remote security guard.

Let’s look at a scenario to show just how safe you make them. You are at home watching your business on the computer using DVR viewer software connected remotely to your surveillance system located at work. The DVR of the surveillance system is connected to the router at your business so that it can be accessed over the Internet. You log into the DVR viewer and are able to see your employees talking to customers and doing the usual evening business activities. Everything looks to be good and in order when you suddenly see some shady characters looking at the counter and casing the business. Your employees are busy with other customers and they do not see the possible danger. Now, you have the choice of one of two things. You can call your business and alert your employees to keep an eye on the shady customers, or you can wait to see if something happens and if it does, call the police immediately.

The point is not which option you decide to take, as both will greatly improve the chances of a safe outcome for your employees. The point is that you have the options , and without the shady customers even knowing it, your surveillance system has provided an eye in the sky that they have not anticipated.

There was a time, long ago, when having this sort of sophisticated set up required high priced security cameras and CCTV equipment that could be used to monitor your business remotely. This meant huge equipment and installation costs, and for most companies, it was simply not worth the price on the off chance of a robbery.

Things, however, have changed incredibly and that is no more apparent than in the current prices of surveillance systems. These systems will record video of what is happening in the store digitally onto the hard drive of the DVR. Upgrades are available if more video storage is needed and the surveillance video can be backed up using a CD burner or USB drive. This system is also networkable which means that you can access your cameras remotely over the Internet using the DVR viewer software that comes with the system. You probably already have an Internet connection and computer at work, so all that is left is buying a networkable video surveillance system.

While crooks and robbers will not know you have a remote viewable video surveillance system setup that can be monitored from anywhere, your employees will. For them, they will see the measure of setting up the security cameras as an indication of how you care for your employees and your desire to keep them safe. They will feel more at ease at their job when the ‘eye in the sky’ is watching to alert them of any danger, while at the same time, giving them the ease of mind that comes from knowing that if someone does rob the store, they won’t have to wait to call the police until after they leave and that video will be captured to help prosecute.

Setting up a surveillance system in your businesses means that it is much harder to get away with robbery and you are not only going to keep your employees safe, you are helping to keep your businesses safe for everyone. When someone robs a store and gets away with it, they begin to think they are invincible and they choose to attempt the robbery again. This puts others in danger and given enough time, could lead to a tragic death. However, with remote Internet surveillance monitoring provided by networkable DVRs, you can have the police capture a robber before they even know what is happening, or have left the store.

It is not unusual to think of a surveillance system that allows you to monitor a location remotely as something that can make society not only safer, but also better. When you are thinking of ways to make your business safe for employees, you may want to consider a video surveillance system, because security cameras make the world a safer place for employees and customers alike.

Here at securitycameraking.com we have an abundance of surveillance systems all that will work for you, your business, your family, and help keep them all safe. So visit our site or give us a call at 866.573.8878 so we can assist you in getting the right system set up for you and your needs.

How Do I Know Which DVR Is Right For Me?

Written By:
Monday, December 3rd, 2012

4 Channel Ultimate Series H.264 D1 Realtime Security DVRWhen looking for a DVR, there are more options out there than models of TVs.  That is why I am going to discuss certain topics that are important for you to know and understand before buying your DVR.  How do I decipher some of the terminology?  Why should I spend my money on one over another?  What are the biggest differences in units?  What brands are the best?  These are just a few of the questions that you may come up with when trying to purchase a security system.

How often have you been watching the news and have seen footage from an incident shown, and you look at the screen scratching your head wondering what you are looking at?  There are a couple of factors that come into play with the footage that you are seeing.  There is the quality of the camera that was used with the system.  The quality of the cabling that was ran from the DVR to the camera.  And what I feel to be one of the most important factors is the DVR itself.  When it comes to a quality surveillance system the heart of the system is the DVR, the backbone of the system is the cabling and power supply, and the cameras are the eyes.  If your main component is weak the rest of the system will suffer.

One of the biggest things you need to worry about with regards to a DVR is the recording resolution.  A lot of systems out there will tell you that you are getting a high resolution system.  This is normally because they don’t want you to research the system any more and generally said when they are giving you what they consider to be high resolution cameras.  They do not want to talk about the fact that the images the DVR will be recording are subpar.  It may look decent when you are watching the screen live, but when you actually go and try to see something in the recorded footage it will not look like what you were just watching live.  This is because of the recorded image resolution.  When it comes to the recorded image there are 2 factors resolution and frames per second (fps).  The resolution is the biggest of these 2 factors. There are several different resolution that a DVR can have the ability to record at. They are QCIF, CIF, 2CIF, HD1, 4CIF, D1, or 960H.  The quality of the resolution increases from left to right with QCIF being the lowest and 960H being the highest resolution that a DVR can record at.  Most DVRs on the market can record at the lower end of the spectrum, but not all of them can record in the 4CIF/D1 spectrum and even fewer can record in the 960H.

CIF is short for Common Intermediate Format, which is a common video format.  Its resolution is 352×240, which means that those 700tvl cameras that you spent good money on are wasted.  This is because you are only getting approximately a third of the potential tvl being recorded.  The rest of the tvl’s are being discarded.  This format was very useful when technology could only support it, but we are well above that now.  This type of a format is relevant for remote viewing so that you get a more ‘live’ picture and are generally limited to the bandwidth of the ISP provider.  Viewing your system remotely in CIF is a better solution than having network drag or high latency with your ‘live’ view.

Quarter Common Intermediate Format or QCIF has a resolution of 176×120.  Now if your DVR is only recording in this, throw it away and step into this century.  This format will take your high resolution 700tvl cameras and only give you about a fifth of their ability.  The only reason this format should currently be used is for mobile phone viewing.  It allows for the images to be transmitted at a greater rate over a cellular network with less latency.  You typically are viewing these images on a much smaller screen, so the loss of resolution isn’t as apparent as viewing it on a normal monitor.

Twice Common Intermediate Format or 2CIF has a resolution of 704×240.  This resolution is starting to give you more use out of your 700tvl cameras.  You are still getting a smaller image horizontally, but a more natural vertical resolution.  So your 700tvl camera will give you all of the detail that is available to you based on the vertical resolution.  If you are recording in this format it will save you space on your recorder, but you are still falling short in the horizontal resolution of the image.  This can sometimes be referred to as Half D1 or HD1.  They can also have a resolution of 352×480 which in today’s monitor world does not make sense.  It made more sense when you were dealing with square monitors.

The best choice for today’s high resolution cameras is Four Common Intermediate Format or 4CIF which has a resolution of 704×480.  This is commonly referred to as D1 resolution as well.  This comes in very useful for capturing all of the details that are possible in an analog CCTV camera.  A 625tvl camera will be the maximum tvl’s that will be needed to maximize your images with this recording format.  That being said, more is often better.  This is because of other features and components that are often used with higher end cameras.  That will be discussed in a later article.

The absolute highest rate of resolution that an analog CCTV system can record at is referred to as 960h which has a resolution of 960×480.  What this allows for is an even larger image for more detail Complete 16 Channel Ultimate Mini DVR Security Camera Systemin the image.  This resolution requires 2 things to properly be utilized, a DVR that can handle this resolution as well as cameras that can support it.  Your cameras need to be high resolution with good sony digital signal processors (DSP) that are designed for 960h and a federal series DVR.  The Tech Pro Federal Series DVR is an amazing unit for the absolute best performing DVR on the market.  This setup is amazing for upgrading a system that has all coaxial cable in place, but you want to get HD without re-wiring your whole place.

Frames per second or FPS is another thing to consider when looking for a DVR that best suits your needs.   Most DVRs on the market, if they can record at D1 resolution, do so at 7fps.  This is generally suitable for the general consumer market, but if you are needing to see in realtime you need a unit that will record at 30fps.  This is very useful when reviewing the footage because you have more frames in a small period for you to better see what occurred.  At 7fps, an object can be in one place and then in the next sequence a little ways away.  This is why a lot of DVR manufacturers will sacrifice the D1 for recording in CIF.  Me personally, I would rather have a greater image quality and loose a little on the fps than have real time and a poor image.  The better the image quality to start with when degrading the picture the better that degraded image will be.  When you start off with a poor image and then have to degrade the image to see what you are looking at, you lose.

My DVR of choice is the Ultimate Mini Series, it has great features in a compact package.  You get D1 resolution at 30fps on all channels, it is able to accomplish this with its dual core processor.  You also have some pretty cool features like audio inputs, alarm outputs, video matrix, and an HDMI video out display to name a few.  The DVR is about the same size as a Bluray player, so it can fit in almost anywhere.  There are a lot of different units on the market that may suit your needs.  What you want to do is decide on what the most important features are for you and then proceed with building your system.  Just remember that all things are not created equal and you may be better off saving a little money to get you a unit with features that will help you when you need them rather than just getting anything.  The last thing that you want to do is find out that you wasted your money when you really need the footage to help you capture the perpetrator.
