Driving home last night, and saw a flock camera pointed in to a field and not at the roadway.

This made me unreasonably happy.

Given how the cameras use ball mount clamps and simple hex tooling, this is a very effective DoS attack. The camera isn't disabled, and is still reporting as normal, just not uploading any traffic, because there is none.

YES!!!

@kajer black spray paint has gone up in price too....

@bosh This begs a question...

The device camera is triggered to record by an IR motion sensor... and then the yolov3_tiny crops the camera frames for objects before uploading to AWS.

So... if the camera lens was painted black, and the IR sensor was free to detect motion... Then it stands to reason that the yolov3_tiny model would detect nothing and upload nothing.

This means, no clips of blackout video are being uploaded. But, once someone remotely access the video feed, then the problem is obvious.

When I was testing the cam I had in my garage I found blocking the IR motion sensor prevented video / object detection routines. so a piece of vinyl tape over the hole under the lens also stopped the device from doing a thing.... and viewing the camera feed would not be obvious why recording isn't being triggered...

@kajer Old and busted rule 9: Always carry a knife.

New hotness rule 9: Always carry a decent multi tool.

@nuintari @kajer ok, but I know my impulse control. I'd get myself into so much trouble poking at random shit 
@nuintari @kajer
Wait, isn't there a Rule about swiss army knives?

@FritzAdalis @kajer Yes, yes there is.

The nuis rules are generally for cyberspace.

The Gibb's rules are for meatspace.

There is no defined precedence.

@kajer Everyone needs to hold 80’s police movie nights next to them and crank up the sound.

@badsamurai Since all new cams also do sound recording for "shot detection"...

YES

@kajer when the cops show up tell them it’s a law enforcement appreciation party.
@badsamurai because Police Academy was a historical snapshot LOL
@badsamurai I've often wondered if snapping a belt right under the cam would match it's gunshot detection threshold?
@kajer @badsamurai They used to have so so many false positives for things like that, tailgates slamming, etc. Worth a try.

@cR0w @kajer @badsamurai actually, what you're looking for is the old 'pop cap' paper we used to have in the 80's.

These things.

@rootwyrm @kajer @badsamurai Yes! But are they loud enough? Maybe right next to the mic or in a coffee can. We used to put rocks in coffee cans with those and toss them. And hit them with hammers, stomp them with our classroom chair legs, etc. Good times.

@afeinman @cR0w @kajer @badsamurai our resident expert would have to test, but I also assume the enclosure and lens are ABS. Which means you definitely should not spray them with acetone or acetyl salicylic acid.
@rootwyrm there are plenty of sticky substances that don't do any harm.

@afeinman @rootwyrm

Acetylsalicylic acid is the chemical name for *drumroll*…

Aspirin

@rootwyrm @cR0w @kajer But the only soft spot left in my heart reserved for animals doesn’t want to scare pets and wildlife :)
@badsamurai @rootwyrm @kajer Pringles can for better concentration of the sound. Better aim and range. In theory.
@rootwyrm @cR0w @kajer @badsamurai I would put a roll of those behind car tires on my friends driveways (to run over when they backed up). I was never around to see/hear the results, so have no idea how loud it was.

@eryops @rootwyrm @cR0w @badsamurai

Caps? they required really high pressure to trigger IIRC. Once when I was a dumb kid, I decided it would be neat to soak the roll of caps in gasoline (gas can for the mower) for a minute before loading and using the capgun.

πŸ”₯

the flames were awesome, the rapid succession of the rest of the caps all going off at once? once was enough,

Now,,, if you ever got your hands on railroad torpedos Those are LOUD!!!

@rootwyrm @cR0w @kajer @badsamurai Well having been young a long time ago and stupid, you know slamming a heavy hammer into a roll makes a big bang. Also makes the hammer explosively fly out of your hand if not holding it tightly.
