How to I see if an IP camera is connected to my network?

http 404 error with the ip:80 and also with the name,pw@ip:80

tried rstp and it opened VLC. Asked for the password. Got an error due to an @ in the password.

I will change that and try again. That could be the problem with the http as well.

  Connection failed:
 VLC could not connect to "h0m5@xxx.xxx.xxx.xxx:554".

 Your input can't be opened:
 VLC is unable to open the MRL 'rtsp://office:pw@xxx.xxx.xxx.xxx:554'. Check the log for details.
