How to set up DVR to watch CCTV security cameras over Internet

Watch CCTV security cameras over Internet (Tutorial)

How to set up a DVR to watch CCTV security cameras over Internet from a remote place, if you have an Internet connection with a static IP address

1. Connect your DVR to your router
2. Use menu on your DVR to assign internal IP, gateway and port number.
   
   This Local IP must be in the same Gateway range as your Router. If you are unsure, check the Router and locate the Status section.
   
   Alternatively use the the Command prompt of Windows 8/7/Vista/XP/2000 and type in ipconfig.
   Look for Gateway. If the Gateway is 192.168.1.1, then you can make the DVR's IP anything from 192.168.1.2 to 192.168.1.255.
   
   Also you will need to use the same SubNet Mask, which is typically 255.255.255.0, and the same gateway.
3. Next find out what port your DVR uses. The easiest way to do it is by reading the manual of your DVR. See the network section of the manual.
   
   If your DVR comes with network software, it may show the port number in the connection area.
   
   Check the Server software/Programming (Network section of it) to see if the port is listed there.
   
   In many cases the port number will be 80, which is an HTTP port.
4. Set your router to forward the chosen port to the internal IP address of DVR.
   
   To access the Router itself, use the Gateway you just located. If the gateway is 192.168.1.1, then enter that into the location edit box of your browser and then click the Enter button. A username and a password are typically required, but it depends on a router. For Linksys use "admin", "admin". By default DLink doesn't require any username or password (Please note that it is highly recommended to change the default password).
   
   
   Once you're logged into the Router, go to the Applications & Gaming Section / Servers of the Router and add a Server/Application. Enter the port number and select TCP only. Where it says Port 0 to 0 enter the same port number twice. Or if your DVR uses, for example, ports 3550, 4550, 5550, 6550, and there is nothing else utilizing these ports in between, then you can actually just enter one line, 3550 - 6550.
   
   Enter the DVR/Cameras internal IP.
   
   Enable it.
   
   
   
   Example:

   If the port was 1025, and the Local IP is 192.168.1.201, then the corresponding settings will be the following:
   
   NAME = Anything you want
   Port = 1025 TO 1025
   TCP/UDP = TCP
   LOCAL IP = 192.168.1.201
   ENABLED = CHECKED
   
   or
   
   NAME = Anything you want
   Port = 3550 TO 6550
   TCP/UDP = TCP
   LOCAL IP = 192.168.1.201
   ENABLED = CHECKED

5. Set up additional entries for as many ports as your DVR uses, but use the same local IP address. Check your DVR manual and it's networking section for all additional ports required. Also check the DVR software itself.
   
   If your router has enough free entries, you can separate them. Use it like DVR_HTTP for the browser port, DVR_AUDIO for the audio port, DVR_VIDEO for the video port, etc.
   
   If you are going to use Virtual Network Computing (VNC) to a PC DVR, then you will need to set up port 5900, and perhaps call it VNC_DVR, for example.
6. If you have a static IP address, then you should be able to enjoy viewing your CCTV cameras from a remote place by now. Just enter your static IP address in a browser in a remote location, and your router should forward packets to your DVR.s
   
   If you have a dynamic IP address, then you will need to set use a Dynamic DNS service, so that you can access your DVR by a memorable address.

One of the biggest challenges setting up a DVR to watch CCTV security cameras over Internet from a remote place is that all routers are different, so there are no general instructions on how to set them up. You need to refer to the router manual provided by the manufacturer of your router.

Another problem is that some Internet providers do not provide static IP addresses using dynamic IP addresses instead.

How to set up a Dynamic DNS (DDNS) service and DVR to view CCTV cameras over Internet from a remote place, if you have a dynamic IP address

First, you need to find a Dynamic DNS (DDNS) service. Free services usually don't last too long or have their limitations. Paid Dynamic DNS services cost about USD $20-$25 per year. If you have your own server with BIND, you may set up your own Dynamic DNS service. Let's assume you will use a 3rd party dynamic DNS service (DDNS) for your DVR.

• Create an account with a username and password at a Dynamic DNS service (free or paid).
• Login to your account
• Go to "Account" -> "My Service" -> "Add Host Services" -> "Add Dynamic DNS Host"
• Enter and select hostname
• Enter the IP address of your computer
• Click "Add host"
  In your DVR software:
  • Find DDNS network settings
  • Enable DDNS
  • Enter username, password and hostname from your Dynamic DNS account
  • Apply the settings

Now if your IP address changes, your DVR software will send the data to Dynamic DNS (DDNS) service, so the data there will be updated. This allows to access your computer from a remote location by using a memorable name (user-friendly hostname) instead of a weird IP address.

p.s. Please note that some routers can also be configured to work with DDNS, so instead of configuring your DVR software, you may configure your router.

Problems setting up a remote DVR viewing when your ISP uses network address translator (NAT) or proxy server

When you check the IP address of your computer, please make sure it is not in the following ranges:

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255

The IP addresses from these ranges are common in home and office local area networks (LANs), as globally routable addresses are scarce, expensive to obtain, or their use is not necessary. These addresses are private because they are not globally delegated, meaning they aren't allocated to a specific organization. If such a private network needs to connect to the Internet, it must use either a network address translator (NAT) gateway, or a proxy server. If you have such an IP address, then I can't help you to set up remote DVR viewing. You need to ask your ISP whether you can get a real IP address or port forwarding.

How-to Connect a Security Camera DVR to a Wireless Router

Sometimes customers install CCTV DVRs in locations that do not have a hard wired Network connection. For example, maybe you ran all of your RG59 or CAT5 cable for your security cameras back to a closet where your DVR will be located, but you had no way to run a network cable from your wireless router to that location. Most CCTV DVRs and network recorders for IP cameras only have a wired Ethernet port (no built-in WIFI).
Now, you want to view your security cameras remotely over the Internet and in order to do this, you need to connect your DVR to your router.

What can you do?

Wireless Network Diagram to Connect DVR to WIFI Router

This is how it works using the above example installation.

1. There are two X-Den security cameras hard wired to an DVR surveillance DVR. using RG59 coax cable. However, this solution works the same if you are using IP cameras with a network video recorder.
2. The DVR only has Ethernet port for network connectivity (no built-in WIFI).
3. The Ethernet port of the DVR is hard wired to the wireless bridge using CAT-5e cable. I am using a WIFI-AP3500 for the wireless bridge. The WIFI-AP3500 is actually a multi-purpose wireless device. It can be configured as a router, access point, or bridge. This one is configured in bridge mode which enables it to connect to our router.
4. The WIFI-AP3500 is configured to connect to the Linksys / Cisco wireless router using the WIFI.
5. The Linksys router is connected to the Internet. This can be using a DSL, cable, dedicated fiber, or any other type of modem / Internet connection.

IP VS Analog CCTV Systems

There are two types of closed circuit TV (CCTV) systems: digital and analog. With digital CCTV, a digital camera views the scene in front of the lens and broadcasts the video images as a digitized signal over a LAN line (Local Area Network) where it's then transmitted to a computer or server. In turn, the server manages all of this information. Depending upon the software used to manage the digital images, it can record, display or re-transmit the images to anywhere in the world.
True IP-based digital surveillance uses CCD cameras that employ signal processing with the purpose of sending packetized video streams over the LAN through a Cat 5 cable rather than a coax cable network. This system provides more intelligent data mining and information retrieval. If security is an issue, full digital surveillance offers the added advantage of data encryption opportunities to protect against image tampering; something not possible with analog recording.
The main difference between the two camera types is the way in which the video signal is delivered. Analog cameras turn the video signal into a format that can be received by a television or other receiver such as a VCR or monitor. An IP-based camera, also known as an IP network camera, digitizes the video signal using a specialized encoder that contains an onboard web server. This allows the IP camera to act as a network device, thus allowing captured video images to be viewed not only through an existing network, but also through a web browser that can be accessed through the Internet.
The advantage of a digital system over an analog is clear, and by that I mean literally - better picture quality. After all, the whole point of a Video Surveillance System is to see exactly what is happening in the moment. How many times have you heard about or seen grainy footage of a perpetrator committing a crime that was taken by a traditional CCTV system? Most often you can't make out more than a fuzzy form and the images are useless to law enforcement. In addition to quality, digital cameras also cover a larger area. For instance
While an analog camera is ideal if you want to monitor one location from a fixed position, an IP camera is more flexible and can enable more sophisticated surveillance, recording and review. IP cameras can deliver high definition or megapixel images, which give greater detail and can cover a greater range. All the more, they can be powered over a network using Power over Ethernet (PoE) that does not require a separate power supply. Some IP cameras have audio recording built in which allows recorded messages to be broadcast automatically to warn people that they are being watched. However, this functionality can be integrated into any camera's housing, and is not a specific benefit of IP. Both types of cameras can feature infrared technology to capture full-color images during the day and black-and-white images in low light or even complete darkness.
Even at the highest resolution available for CCTV, the clarity of rapidly moving objects, such as a person running or speeding car, has long been problematic in security and surveillance applications. In an analog CCTV environment, a rapidly moving object will appear blurry. This is because the video signal, even when connected to a DVR, interlaces to create the images. Interlaced images use techniques developed for analog TV monitor displays, made up of visible horizontal lines across a standard TV screen. If you happen to have shopped for a new TV lately you are probably aware that 1080i is not nearly as good as 1080P. Interlacing divides images into odd and even lines and then alternately refreshes them. The slight delay between odd and even line refreshes creates some distortion - only half the lines keep up with the moving image while the other half waits to be refreshed.
A better way to understand the differences between analog and IP-based video surveillance may be to compare the two and how they work:

Analog or CCTV+DVR
• Easy to use - operates like a VCR
• Changing and rewinding tapes - humans may interfere with effectiveness
• Image quality is poor
• Storage tapes wear out over time
• Broadcasting images live isn't an option
• Storage is bulky
• Uses analog recording, recording in low-grade picture quality and inability to search and track easily
• Adding DVR systems must be done in blocks of 16 channels
IP-based
• IP-based recording means instant transmittal of images anywhere in the world
• Can monitor multiple cameras from one remote location
• No decrease in recording quality over time or with repeated replays
• Digital picture quality far superior to analog
• IP-base recording is highly compressed for easier storage and can be transported over a variety of media
• Digital images can be encrypted for security purposes
• Updates and add-ons are relatively inexpensive through software packages and Internet computer networking
• Adjustable frame rates
• Remote or shared viewing may be done over the Internet or a wireless connection
• Standard IP video compression techniques are used
• IP surveillance cameras may be added individually or in groups according to your needs
