Effects of The Ipod

Just a week ago, I was headed up to a concert about two hours away from home. We sort of consider these concerts to be miniature road trips. In the past, we'd pop in a cd, crank it up for a while, and then we hop into a discussion about chicks, politics, potatoes, etc. The music being played kind of took a back seat until we ran out of things to talk about.

Well, this trip was a little different. The difference was no one brought any cds. Instead two of the group brought Ipods which played through the radio with an FM modulator. In the past, we'd flip through cd case after cd case looking for that one certain cd, but once we had found that one cd we were committed to it. On long trips, it was rare to take a cd out without listening all the way through it.

Well, enter the age of the Ipod. The Ipod has done to music what cable has done to television. You now have the magical curse called choice? Of course, all choice does is lead to indecision. I'm not sure if watching another person flip through 200 satellite channels on TV drives you crazy, but it certainly does me. For two hours, I watched two people do nothing but flip through song after song. It was VERY rare if we made it through one minute of a song. In fact, I doubt if we made it through an entire song at all.

While it does seem great being able to carry 41 days of constant music in your pocket, I have to say that the average Ipod user may be missing out. There was something to listening to an entire cd on a trip that helped define the great albums. We all have those 5 or so records that we'll never get bored with that we can always listen to all the way through. How would you know what a great record was if you had never had to listen to it all the way through? Sure, sometimes it seamed like a curse having to listen through a crappy song, but cds took care of that pretty easily. You just hit the skip?button.

The real tragedy is there really wasn't that much music listening going on. It seams that a device that is designed to make it easier to listen to more music has a drastic downside. If people do little more than flip through song after song with their Ipod, then the Ipod is taking away from people's musical experience.

Yet, people still try to buy bigger and bigger Ipods. I remember thinking that 10GB of Mp3s was an enormous amount of music. Now 60GB versions are very common. I couldn't imagine who really needs 41 continuous days of music without repeating a single song. If you turn the Ipod off for sleeping, you are sitting at right at 60 days of music without repeating a single song.

Where Are All Of These Songs Coming From?

So how are people filling up their Ipods? Are they buying songs at $1 per song from Itunes? I've got a gut feeling that most of them are not. Assuming a one minute MP3 uses 1 MB and the average song is 4 minutes long, it would cost $15,000 to fill up a 60GB Ipod. Ouch! I don't know too many people who have spent $15,000 on purchasing music. I DON'T KNOW ANYONE WHO HAS SPENT $15,000 ON MUSIC!!

It seams pretty clear that if the average college kid were paying $1 per song, they would probably wouldn't need an Ipod much larger than 1 or 2GB. Yes, I'm aware that you can store other data on an Ipod, but I don't know too many people who plan to haul around RAW video data on their Ipods.

So Who Is Getting Paid?

The labels still seam to be afloat even if they are signing a smaller quantity of artists. They certainly don't seam to be as excited about their profits as they may have been ten years ago. It's no secret that if the labels aren't getting paid, the artists definitely aren't getting paid either.

Music Is Expendable!

I remember just a little over 10 years ago. My family was low on cash. I decided that I wanted a rare Nirvana import called Outcesticide 3. The cd cost $30 and had to be ordered from Japan. I decided that the only way to buy the cd was to not each lunch at school for a month. (I was too young to get a job). So, I did without a meal each day for an entire month so that I could save $1 per day and order my Nirvana import. You could imagine how I felt the day the cd finally came in. I had put myself through torture for an entire month to get that cd.

I was at an uncle's house recently. My cousin was on his computer. He decided he wanted to listen to some rare Nirvana songs. He opened up his favorite peer to peer download software and typed in Nirvana or whatever. In about 10 minutes, he had almost the entire cd that I had starved for a month for.

While it is exciting that technology exists that makes it faster to download a song than it is to take the cd out of it's case and place it in the player, it seams that this somehow makes the music worth less to the individual. When a listener has to sacrifice for an album, the album is a little more memorable.

I mean I can remember the exact day I purchased many of my favorite cds. For example, I remember being 16 and buying Goo Goo Dolls, A Boy Named Goo? Me and my buddy were driving 90 mph on the way home like a bunch of immature idiots. It turned out that we had passed my mom without realizing it. When I got home, I was doomed. (That one didn't end on a happy note).

Uhh, good luck having any stories about how fast you downloaded an mp3. Good luck even remembering the day you downloaded a given mp3.

So who is winning with the Ipod?

Is the music listener winning? They now have a portable music machine that can hold 2 million zillion songs. Of course, the mp3 player costs about 3 times as much as a portable cd player did 10 years ago. With the luxury of having so many musical options, some people spend a lot more time flipping through songs than they used to. Ipods can hold an enormous amount of data, but this just leads to people blindly downloading every song under the planet. It's cool being able to hear a song, but having a free library of every song under the sun can make music expendable. Of course, the labels and artists don't seam to be winning.

In fact, I can only think of one guy who has really won from the Ipod...Steve Jobs, founder of Macintosh.

This is first article from two part series looking at the seemingly easy task of setting up Internet connection to security DVR. While this article will focus on general steps involved in proper connection forwarding to CCTV DVR, the part two is all about dynamic DNS support and workarounds. Before we step into the main subject, I like to explain very briefly a few key aspects of Internet connection for those of us not familiar with term like IP address, DDNS, port forwarding or IP mapping.

Terminology:

Every computer or other network device, in our case CCTV recorder has its own address called IP address, much like your home address it allows the information to find its way in enormous world of internet. IP address has four groups of numbers separated by dots; the number range is between 0 and 255. There are two separate networks that we need to take into consideration, LAN for Local Area Network and WAN for Wide Area Network. LAN has its own IP addresses and handles connection on local network devices (computers or devices located in your home or office network), if WAN IP is your home address than LAN IP would be your apartment number.

WAN IP is an external address visible to every user on the Internet. We will explain rest of the terminology as we go along.

Setup:

The best way to explain and clarify surveillance DVR connection setup is to use an example. In our example, we will setup DVR model VDV-074 from DVRExperts thru Netopia Router/Modem combo currently used by AT&T DSL provider with static IP service, I will also use Linksys WRT54G Router for Cable DSL connection. Security DVR recorder needs to be connected to the Internet through Router and Modem, in some cases Router and Modem are all in one devices, for example Netopia Routers.

For standalone Modems please connect the Internet out to WAN port, on your Router. Connect CCTV DVR and computers to available ports on the Router as well. Your Router will need to be setup now to log in to the Internet service provider and establish connection.

Netopia Router users:

Open up browser on your computer and type into the address bar your routers default IP http://192.168.1.254. User name and password window should appear; the default user name and password for Netopia Routers are admin for user and serial number of your Router for the password.

Select Configure followed by Quick start link, type your Internet service providers user name (email address) and your ISP password. Click submit and alert icon located in upper right corner (I know it is strange), finally select save and restart. Your connection should be up in minute or so, click home link to see your connection status.

Linksys Router users:

Open up browser on your computer and type into the address bar your routers default IP http://192.168.1.1. User name and password window should appear; the default user name and password for Linksys routers are admin for user and admin for the password.

The home page of the router has ISP settings, type in your email address as a user name and ISP password for the password, select save or submit. The Router will restart after minute or so, log in again and go to status page to see if your connection status is UP.

If everything is ok and your connection is UP, we can now proceed to fun part of the setup process

There is great number of different security Digital Video Recorders on the market, so please follow your DVR's manual for details; I will only provide the proper settings. In the DVR menu, setup static LAN (Internal) IP for the DVR, in our example we have 3 computers and DVR. Each device has assigned LAN IP address as follows:

Computer 1 - 192.168.1.100

Computer 2 - 192.168.1.101

Computer 3 - 192.168.1.102

DVR - 192.168.1.103

The surveillance DVR will now be accessible within our network by typing its assigned internal IP (192.168.1.103) into browser or connection software. What we need now is to forward the connection from external IP (WAN) which is accessible from outside of our network to the LAN IP of the DVR (192.168.1.103).

Netopia Router users:

Select Configure followed by Advanced and finally IP Maps. IP map table should be empty, click on add and type into IP Map Entry Name text box the name of your DVR connection, in our example I just typed in DVR so I know what this IP map is for. In Internal IP address box type in 192.168.1.103, for external IP address refer to you ISP work sheet and find out what is your IP. In some cases ISP will provide more than one static IP, you can choose one of them.

Click submit and alert icon located in upper right corner, finally select save and restart.

From now on anyone requesting external IP will be forwarded to the internal IP of the DVR (192.168.1.103), therefore the connection should be established successfully.

Linksys Router users:

When setting up your DVR for access from the Internet, you will need to configure Port Forwarding on your Linksys Router. This can be accomplished in one of two ways, Specific Port Forwarding or the DMZ host. The DMZ host automatically forwards all incoming connection requests to a given IP address on your local network. Open the Applications & Gaming section of the router and choose DMZ. DMZ is not secure and should only be used with embedded, non-PC based CCTV recorders.

To expose the DVR to the Internet, enter the DVR local IP address (192.168.1.103) in the DMZ Host IP address box. In some cases you may just want to forward specific ports to your security DVR. If you are running any other device/server that hosts services available to the internet, you will want to use specific port forwarding instead of the DMZ Host, also if your DVR is PC based it is strongly recommended for security reasons, to only forward ports used by DVR connection. Open the applications & Gaming section of the router and choose Port Range Forwarding. Type in the name for the connection, starting port number, ending port number and internal IP of the DVR (192.168.1.103 in our example). Save and exit.

Your connection is now setup properly.

You probably noticed the term static IP in this article, and are wondering what that is.

Well, static IP is what the name suggests an IP that never changes. While there is no problem with internal IP selection; we can use whatever we want or prefer - the external IP, usually is dynamic. The static IP has to be requested from the ISP and is more expensive than dynamic IP. In our case we do want static IP so we have address for CCTV DVR connection that will never change.

Throughout this tutorial I have assumed that the external static IP is available.

Unfortunately in many areas it is not, or the cost is prohibitive. Don't panic yet, there is at least couple of different ways around this problem and I will try to go over each approach in my next article "How to use free dynamic DNS services for DVR connection."
