So J. Kb. “had a feeling” about talking about the benefits of security cameras which roughly translated means: “Yo! Your turn to add something to the conversation.”
I was told a story when I was a kid about the Great wall of China. Supposedly it was indeed impregnable and many lives of enemies were lost trying to defeat it. Its effectiveness eventually collapsed when the enemy prodded and found the common failure of all security systems: The human factor. Guards at one of the gates were bribed and the wall was breached.
We are animals with deeply ingrained curiosity and the need to find answers. While most animals run away at some sudden noise, we concentrate our attention to what caused it and seek to find out an answer. I am not saying it is a dangerous thing to do, but we have other ways to achieve the same results in a safer manner: surveillance cameras. I have spoken about that at a length, so I am not going to repeat it.
The question now is: If you have gone and installed security cameras and even a doorbell camera, why do you need to breach you own perimeter if something looks/sounds fishy? Use the tools you spent and make sure there is nothing outside your perimeter that can kill you.
This is my Mail Lady. She has been in our area for decades and she is as sweet as she can be. She came to deliver a registered letter but even though I knew her, I did not open my door till I made sure it was her and only her. My perimeter was opened because there was no detected or presumed danger.
If somebody I don’t know knocks my door or I have people making racket outside at night, I no longer need to try to gather info via the peephole or crack open the door to gather info: The camera does it for me and either gives me peace of mind or the chance to elevate the DEFCON and prepare accordingly.
So yes, get at least a doorbell camera and keep your perimeter security intact
I haven’t found a doorbell camera yet that doesn’t require an account with someone. That means that livestream is available to an unknown number of people for unknown purposes.
I do have a couple of IP cameras hanging off my house but I had to look long and hard for versions that would just provide a standard rtsp or onvif stream that I could control access to.
