Thank n0fx, the culprit was the firewall (I forgot that last week I installed a new antivirus in my machines). I was able to see both new cameras on sadp and be able to do the set up. However, another strange thing happened. I was expecting that the new cameras to have the default IP 192.0.0.64. I first connected the DS-2CD3332-I (firmware 5.2.5 and on the box 5.3.0) which was shown with an IP from my network and not the default 192.0.0.64 one. When I connected to it through its web interface I was prompted to change the password at it went automatically to the `Security`tab. The second camera (DS-2CD2232-I5 with firmware 5.2.0 and on the box 5.2.3) was shown with the default IP 192.0.0.64 and when I went to its web interface did not ask for password change and opened the `Live View`tab. I did change the default 12345 password on both cameras, but should I be concerned and do more things on the security side. Thanks.
