    A lot of the new systems can use battery powered cameras that are motion activated - they can last for a month+ on battery because they only turn fully on when they detect motion.

    You’re right though - if it’s mission critical don’t rely on wireless.

      Some of them even have solar panels as well. It’s very useful if you want to DYI installation without having to run cables all over the place (data and/or power).

      This Wi-Fi jamming stuff does seem like a huge issue. I was actually considering wireless down the line, but maybe a system with proper wired connections would be better.

        Power over Ethernet (PoE) requires one wire for both data and power. You also need a PoE network switch, or a “PoE injector” which is basically a power brick that adds power to the network cord.

          Yeah, that would definitely be the way to go. You still have to run the cables all over the place, whether it’s one or two. I totally get why people go with wireless.
