Re: [Phantomjumper] Security camera jammers.Anybody use them?
It depends what you need, in a situation where if you're spotted at all, you're busted this is useless, like a stairwell nobody is supposed to be in. But just in a scenario where having your face recorded on camera could get you busted, like riding up an elevator of a particular church building in SLC utah

this is the best solution IMO.

Its not going to screw with camera systems and tip off security guards, and also not a fucking ski mask/bandana or something that draws a ton of attention to yourself/makes it look like you're going to rob the place.
If you can tinker a bit this is ideal,

Pick one of those up, and replace the LED's with infrared ones, and then it could be clipped to any hat/helmet/head band etc to meet the needs of the particular jump. And while i would imagine a security camera jammer is illegal, and would probably get you in a huge mess of trouble in court, this is at least a bit more grey area.
