The SSID does NOTHING to discourage casual driveby snooping and poking at your settings. Also putting your security cameras into the DMZ is good ONLY if they support secured communications. Unfortunately most do not. You are now leaving a way for folks to get at your camera and peer into your home or business. Not a good idea.

Choose a section from GRC’s password generation page for good password.
