Thanks! Had to reset IP address as you wrote.
Thanks again. Now the cameras are working fine, BUT the visibility is terrible in the dark. Is there a way to fix this. What I mean is I also bought some cheaper ip cameras that have built in sensors so that they can see in the dark. It seems a little strange that dcs 3420 can't see in the dark or is it something I need to set in the settings.
Thanks in advance and God bless you.

Hah! that was just a guess.
I don't know "how bad" your night image is, but I don't think you are going to be able to see in total darkness.

This is a live 3420 cam, so it looks like it is getting dark there. I guess you could check it whenever it's night time there.

I don't see anything about an ICR switch on newegg.com description, and I'm not going to read the manual again, but it appears there is only a low light sensor. So adding infrareds separately probably won't help.
Maybe someone else can clarify.
My DCS 2230 has a Minimum Illumination: 0.12 lux.
The 3420 is Built-in 0.5 Lux Sensor for Low-Light Conditions.
You might try turning up the brightness in the software settings if that is possible. I can see a lot more with my 2230 doing that.
