Here is my advice on what you should do
1. You have already scaned the whole network that you could possibly do
2. What you need to do now is
-> find a software that will scan every IP address on the whole network and Scan EVERY single port open - Once it has scanned all ports - it will now grab all the banners off the ports for example
on ip 10.0.0.7 has ports 21 - 23 - 3306 on it when the banner scans those ports its going to output via file > /tmp/scan.txt - and display the banner such as
port 3306 -> banner > Mysql Version X
port 21 -> banner > Proftpd
port 80 -> Web Camera Software Version X
Now you know what ip + port is located on the network and now you have found the camera
If that does not work
Locate your local School office Principals - Assistant Principle - or any Supervisor
you have found those out you need to get the ip of his computer
Simply send him an email and wait for him to simply reply back
Now you have to get his account information
Simply start a MiTM attack on the subnet his ip is located on
Go talk to him and say hey someone stole my stuff can you see who done it on the camera?
behind the doors your executing a sniffing attack on his system
which now allows you access into his computer now you have access to the Camera System
and boom your done
----------------------------------
Also some networks have different Jack ports you will see the common color " blue "
but then there are other ports specifically designed for IT department , School officials , etc etc etc
it might be a color of orange , yellow , or whatever the Field technician that installed the cable had put in
plug your local computer that your on into that port - or a laptop
and start sniffing
and let the Fun begin
Have fun
