Wireless anything related to security is pretty dumb. Wired is better!

Truth. Wired and wireless systems are not all that different in terms of what they transmit at this point, but wired systems have the advantage of keeping their communication stream isolated in the wire as opposed to the shared EM spectrum. It's essentially another layer of security. Can someone tap the wire? Sure, but it requires extreme physical proximity that an RF attack does not.

This is the way. When I design factory automation systems or surgical robots it's all wired. Anything mission critical needs to be, or the mission is not critical.

I guess wearing mask is a good way to circumvent that too.

What prevents the same thief from just cutting your "wired" fiber/DSL/whatever? Or the power, for what is worth.

  Holding/bringing a device that disables every camera is significantly different and less risky than climbing up on ladders cutting each cable going to each camera. As for cutting power? UPS/battery backup. That's defeatable too. At some point you have to say you've reached your limit. Generally you just have to be more secure than comparable targets, though. Someone using WiFi jamming on poorly thought out security is looking for easy targets, not complicated heists.

    I disagree. Possession of a jamming device is illegal in many jurisdictions. Wirecutters are not. I could kill all data communication in most buildings out there just by sneezing in the wrong cabinet (personally experienced). And then what are your wired cameras going to do? If the answer is "make loud noises", well, that's pretty much exactly what wireless cameras could also do. There's a reason 'professional' alarms generally prefer wireless connection and battery power (and loss of connection is generally an alarm-raising event).
