In my early days of using the cameras I did use the listen in and talk function of my cameras, however I rarely use that now.
In my state it's unlawful to (secretly) listen to anyone who might be outside of my home. They have an implied sense of privacy. So... I've always complied and never used any device to listen (or even connected a device so as to have the ability to hear/listen).
But
now considering setting up an intercom with a camera (like a Ring...
which is apparently legal now). As I am leaning towards an entire system that is phone based. I am also going to be adding an "indoor" (my 1st) camera with motion detection to supplement my alarm system(s). Which I hope to make my 1st phone location based (geo-fencing) setup.
The DVR setup (I have now)... was so good (at the time I installed it) that cameras had pretty much been an afterthought for several years now. It's kind'a nice to have that aspect to "
play with" again.
We all have our reason and desires with automation. Like some others.... I really enjoy the projects and accomplishments. I love what this stuff can do.
