You don't need to go up to a camera in order to de-power it. You just find the fuse box (sometimes located on the outside wall of a property) and just flip all the switches off.
Anywhere between the place you're trying to de-power, and the place supplying the power, is a place you can disrupt that power supply. Bits of equipment like fuse boxes/breaker boxes and transformers are easy enough to alter in a way to cut power to a certain building (or set of buildings) if you know what you're doing.
Also this is technically not legal advice, but please do not try and mess with your power grid in order to do crimes, it's most likely another felony charge or two if you do it.
It’s extremely rare that burglars disable cameras. If anything they typically walk up to the cameras and smash them, or they steal the DVR that the cameras record to. The vast majority of the time they just cover their face and don’t worry about the cameras.
My Wi-Fi router and security cameras are on a UPS. You’re going to have to wait a few hours after cutting the power for it all to shut down. And during that time I’m getting a constant stream of alerts on my phone that the power is off.
[edit] Oh, and I should probably have mentioned that my power arrives in an underground conduit to my breaker box, and my breaker box has a camera pointed at it that you can’t get to without setting off an intrusion alarm first.
With a properly set up modern security system, there isn’t really much short of an EMP that’s going to black out both the security cameras plus the hidden cameras in any timeframe reasonable to be effective for a burglary.
For that you need the human factor so that the warnings are being ignored by the time any burglary is attempted — or just move fast enough and disguised enough that nobody can catch you in time.
But these days with gait recognition being a thing, you’ll still probably be ID’d.
