Wired vs wireless... With anything securityrelated, it should really be wired. At least cameras. It's very, very easy to just run a simple $2 sniffer (eg an esp8266) that sends de-auth packets and thus kicking devices off the wifi.

In our neighborhood, we've had quite a few thefts of skiboxes (the ones that go on top of the car) recently, and several say the security cameras seemed to be unconnected at the time, hinting at some use of de-auther/jammer.
