Is there a conflict as to which NVR controls the cameras? I tried this and it created problems with respect to the camera’s settings. I can set my cameras setting from the NVR.
If you don't exceed the total power per port and the total power of 30 watts. What is your total power for those two cameras? If your cameras are 10 watts or less, no problem.
Instead of using a mechanical relay, use a solid state relay. Operating turn on voltage can be any voltage between 3 to 32 vdc with an output voltage to match your line voltage.
I also found out, if I just "Enable" the SSL (Secure Socket Layer) function for HTTPS in the camera it works without disabling the "Require server verification (https: )" under Internet Explorer.
Thanks for the tip. I could not figure this out either. It does work. I have spent a couple of nights trying to figure out how to download from a Sony SNC-VB635 camera SD card. Thanks
