Multiple Network cameras on an IP Address

[IPGuy]

Hey There,

Quick question,

Is it possible to broadcast multiple cams (let's say 10) on one public IP Address? If so how is this done? I know port 80 usually has to be forwarded, so if you are only using this one port how do you forward the other 9 cameras?

Also, what network devices would you recommend for a high speed network.

I was thinking.
1) Motorola Cable Modem
2) D Link Router
3) D Link Switch

Thanks for any advice.

You can do that by setting up your router do port mapping:

route eg port 8000 to the internal ip of camera 1 (you can even route it to port 80 of the cam)
route port 8001 to the internal ip of camera 2 etc..

externally you have to call your cameras by different ports:

cam1 eg 92.145.23.2:8001
cam2 eg 92.145.23.2:8002 etc

Thanks, is there a limit to how many cameras can be broadcasted from one IP>

The limit is set in your router. However chances are if its a cable modem, the limitation will be bandwidth rather the router OS issues.

Okay,

ABOUT, how many cameras will max out on a modem considering bandwith.

Also what range of ports can I use on a D Link router for multiple cameras?

I THANK YOU FOR YOU HELP!

[Dwayne]

theoretically you can use all ports from 1 - 65000 (plus a few hundred)

If you really want to transmit ALL cameras availabe through one internet connection AT ONE TIME of course your bandwith depends on picture size, frames per second , compression and so on.

I recommend you set up a server the place with surveillance software which records on motion, and sends you an email when motion is detected somewhere

[ICUSecurity]

There is much better ways to do this, many cameras have motion detection built right into the camera. Utilizing that will save you a ton of bandwidth if it is impossible to have a local server.

Remember, cameras that can stream mjpeg can be converted ton on2 on the fly. By converting a stream to on2 and going to a Adobe SMS you are now talking about bps rather then kbps.

btw.. the above mentioned solution is my current independent study for grad school, so if anyone is willing to help out =)

When you say local server, you mean the computer that has the recording software on it, right?

I will have a computer setup with software (probably the axis software) unless you have a better suggestion.

Did you mention what type of connection you are using?

DSL, possibly cable.

[ICUSecurity]

Ok, lets say... You have a 5mbps DSL pipe..

10 cameras at 512kbps = 5120

See the problem?

However most Server Solutions are able to compress the video streams to transmit them better.

For example I am currently working on a 250 camera install. Now they have 3 T1's going into their business but there is no possible way that they are going to allow me to eat up almost all of their bandwidth for the camera system.

So I installed a nice little rack system, hosted 50 cameras per server (its running advanced analytics on specific channels, and while bandwidth wasnt an issue, processor speed was) and networked them all together.

Every group of 25 cameras is on its own wireless link, running at 30 frames a second.

The business has 8 locations across the USA, and we just finished our 2nd. From central office management can pull up any camera at any time from any location in any order. So for example if they want to see every front door of every location they can. Or if they want to see every pump bay at a given time, they can.

The software we use changes the format of the video from a large bulk file into a much faster streamlined file, allowing the connection from remote to occur.

So in short, to answer your question, when you apply software, such as a NVR, the rules of streaming video change a little. You are no longer forwarding ports, but rather viewing a server that is pulling and streaming the video for you.

It would be recording locally, but I would want to be able to view the cameras from remote locations for monitoring purposes.

There are many different software types on the market which all allow remote access through the web. I personally use blueiris (www.blueirissoftware.com) - I know there is better software, more professional, etc etc, I simply tell what I do use (saying that for preventing other users complaining I would recommend unprofessional solutions) but it is worth checking it out.
