It is easy! You have 2 options.
Log in to your router's web interface and look for a list of connected devices and their IP addresses.
Scan your network (choose any of these options):
Windows users: Use Angry IP scanner or Advanced IP Scanner
Mac users: Option A: Run the Terminal app and run “arp -a | grep MAC” where MAC is the cam's MAC address. Option B: Use the app IP Network Scanner (free for up to 6 devices, for more devices you can use the free Angry IP scanner).
