My apartment strata let us view front entrance camera on television. I can view it by connecting the coaxial cable directly on TV. However, when I connect to my cable box (I'm using DCX3510-M) and select channel 398 (which is the security channel), I saw nothing display on the screen (i.e. black screen with a word "Security" shows up). Then, I tried to select channel 399 as my apartment strata told me to select 399, but there is no channel 399 available. Therefore, I want to ask how can I view my apartment security channel on my SHAW cable box either on channel 398 or 399? I saw another similar post on this forum said that I need to do something like channel refresh, if so, how to do this?
Thank you for your help.
