>Portable/directional EMP

When I think of an EMP, I think of the nuclear missile EMP from MW2. Are there smaller EMPs, perhaps even car portable or human portable?
There is so much surveillance-capable technology nowadays that you can't even walk down the street without being captured on 4k HD garage door security cameras and having your face recognized by the law enforcement face recognition databases. Unless you carry a faraday bag to hide your phone from GPS and wear a stupid coronavirus coofmask at the same time, it's almost as if you are automatically identifiable just by virtue of existing.

I was thinking of asking on /g/, but I figured you guys would be more knowledgeable. Does the technology or science exist to create a human portable device to emit electro magnetic pulses to disable/destroy security cameras and phones/computers in a short radius? Purely theoretical of course. I don't want to get you nerds in trouble.
