Software/Hardware device to notify of new devices on network

I'm looking for either a hardware or software device that will notify me, or require my approval before any new device, computer, smartphone, laptop, tablet, etc... gets permission to logon or access to my wifi or hardwired network?

Is there such a device or where can I find something like that?

You can do this for free..
What you do on wireless is to have everyone who has a wireless device that you have already approved bring it into the office. Connect, and let them be on wireless.. While they are connected, go into the settings and take a snapshot of all the MAC addresses on the Wifi.. Go into the settings and change it to wifi mac filtering, and add those MAC addresses.. Now no one who doesn't come talk to you can connect to wireless..

As per the rest..
If you set who can add a system to the domain to just you or the domain admin account.
Then you set DHCP and DNS to require a machine be on the domain to get an address and DNS.. You will then need to be notified of a new machine on the network. (Keep in mind you will need to keep a list of a few Static addresses you can use to add machines to the domain, and remember to change them back to DHCP after they are added)

I had my last place configured like that..
It adds work, but you'll always know what's plugged in..

For the wifi, I guess I can do that, then even with the wifi password, someone still can't connect until they see me so I can get the MAC and add them to the list.  Is there a more automated process?

I'm not referring to adding a PC to the domain, but actually when a user plugs in a phsyical cable into a network jack to just obtain internet access.  I would like to know or have to approve that as well.

It would be so much easier to just have a device on my network that would do that, that wouldn't allow access to the network (wired and wifi), until approved by me.

Yes, I'm looking for a NAC product.  Do trey also work with wired networks?

Also, I'm looking for something very simple to I stall and use, at a reasonable price.  Any ideas?

Sure, they are work for both wired and wireless connection, and also they have their particular requirement on network infrastructure.

The implementation cost is depends the scope, you can assume each device (IP phone, switch, PC and printer, etc.) will consume a node license. General comment for NAC is not a cheap solution.
