I regularly transmit 100 watts on HF using a dipole over my house. That’s never knocked any of my IP cameras out. It’s going to take more power than that, especially if you want to stay far enough away that the cameras can’t get good video of you.
That doesn’t surprise me, it’s a lot easier to interfere with analog video signals and 1kW is a lot of power. Some ferrite beads and better coax can make them much less susceptible to interference though.
CB amplifiers are not well known for producing clean signals, especially when the operator is trying to get as much power out as possible.

You’d be surprised. A CB radio with a high wattage amplifier is enough to scramble analog hardwired cameras when its keyed up.

I’m talking semis with ~1000 watt linears. And analog hardwired cameras. I can watch it happen at work.
