Finding a game cam in the woods with basic bug sweeping equipment is like finding a headlight housing on the ground in the woods at night using a flashlight.
What do you mean, exactly? Most of what you can find in the forest is 'RF reflective' because of the water contents - the trees, the grass, the ground. What's the proposed detection method that is going to discern a reflection from a small PCB from a reflection from a large tree trunk?
edit: first, the camera isn't a retroreflector so you can't just light it up from any direction and get a strong reflection. Second, the kind of equipment that would give you good directionality with a static target is some next generation beam steering radar, that stuff is so expensive you're better off walking around with a 4K camera and then processing the footage with an image detector to find possible matches with images of trail cameras.

The cameras themselves are useful for catching remote area | rural thieves on mine leases, rural properties, etc. They're great for spotting and counting rare and endangered species to better direct conservation efforts.
They just need to outlaw private citizens putting them on public property without a permit. Big fines could be a deterrant. Maybe USFS/BLM/NPS employees need some sniffing devices. The upshot is that if it's got a cellular modem, someone's paying a bill and they can usually be found pretty easily if you have the modem.
With fire seasons going the way they are west of the Rockies, I'd be a little concerned about a bunch of lion batteries scattered through the woods. Just takes one of them to blow up in late summer (say it gets crushed by a tree) and there's a good chance it'll be a multi-billion dollar problem that kills people.
Karens with game cams have done a lot to curtail this.
For my purposes, I've found a game camera extremely useful for finding what and when various critters are eating the garden and other plants in the yard, and to figure out what discouraging and diverting measures actually work. I also get a few pretty cool wildlife pics I'd never otherwise get.
Another question, do you look up salary stats on Glassdoor, etc before you consider open position or asking for a raise? Would you consider it offensive if someone told you to stop cheating and just learn to negotiate better?
Learn the craft so that you can tell from the signs, such as tracks, droppings, markings, etc., and spend the time doing actual scouting and sightings before hunting?
Seems to me you're either enjoying the whole process of learning and doing the sport, or just enjoying the results. If the former, do it for real, if the latter, just buy some game meat from someone who does. Doing everything with excess technology and little craft seems more like cosplaying and just cheating yourself of a real experience.
>>do you look up salary stats on Glassdoor, etc before you consider open position or asking for a raise? Would you consider it offensive if someone told you to stop cheating and just learn to negotiate better?
I'd look at Glassdoor as reading the actual signs in the wild, like reading tracks, markings, broken twigs, etc., not an artificial aid — it's one of the signs in the environment. And like signs in the environment, it's not like a camera, it is often obscured, gamed, and skewed. Similarly, a crafty employee would also contact people she knows and exploit connections to scout the potential employer.
However, putting game cameras, webcams, and/or recording devices in their management offices, HR offices, and meeting rooms would be considered a bit out of bounds, you think?
Additionally if you are hunting for sustenance, as in you really need the meat, then you take the first deer you can find. Waiting for the ideal deer is a good way to not end with a deer at all, regardless of whether you have them on camera or not.
Its funny watch Arduino (ease) programmers try to figure out RF (very hard).
Demonstrably it does detect signals. You clearly don't understand the basics (very easy).
(Note I said easier, not just "prove", for it is indeed only easier.)
That would be convenient for burglars or dishonest cops.
It is, however, factual that people choose to behave differently when they know they are being recorded. That might mean choosing not to commit a crime, commit it elsewhere, destroying a camera, or wearing a mask. While a functional camera can't prevent crime, it can identify those who commit them.
So, yeah, I would think that is evidence that they care about cameras.

How does the device detect very short bursts? After looking up the data sheet of the RF detector I believe you would need additional circuitry to not risk that very short bursts slip through the sampling of the ESP A/D input.
Second, the supply voltage of the detector seems to be 3.0 V to 5.5 V, https://www.analog.com/en/products/ad8317.html
https://www.amazon.com/dp/B07FHZXTCZ?ref=ppx_yo2ov_dt_b_fed_...
Specifications: Working frequency: 1M--10000MHz Measurement power: -55dBm to -0dbm Output voltage: 0.33- -1.65V Detection slope: -22mv/dBm (typical value) Input impedance: 50Ω Supply voltage: 7-15V Size: as the picture Weight:7g
Nope. It is used to find RF-emitting devices, the sort of low-sophistication stuff you can buy online for real-time continuing surveillance. For many decades, the real spy stuff has operated in burst mode: collecting data quietly and only transmitting it at an agreed time or in response to an external signal. To detect them you need to be monitoring 24/7 with a rig capable of triangulating signals that might only last a second or two.
Holy fsck, the build quality must be shitty if even the amazon photo looks horrible (just look at the area around the voltage regulator)
Maybe somebody knows: Is there something similar for the Flipper Zero?
This would be pretty awesome, please advise if there's anything I (or anyone) could do to support you in getting this logic onto a flipper (project support, testing, etc).

I've got a flipper right here. I find it cumbersome to use, but it's a pretty popular consumer product. I'll look at what the wiring cost could be to print a board. I've never done that.
Why do you find it cumbersome to use?
I’d be happy to pay $150 for this.
If you’re imagining you can take $30 worth of parts, sell the finished item for $60 or $90, and sustain that enterprise, it’s time to reconsider your business acumen.
For instance,
"lots of people have started with the idea that they could sell at retail for only 3-4x parts cost and failed"
or
"I have had personal experience trying (and failing) to drive down retail cost of electronics below this rule of thumb"
This last has the advantage of making the advice more personal.
Didn't have to make such a statement because I paid attention to people who knew what they were doing. If someone had been this "insulting" with my attempt to beat Craigslist, OTOH, I'd have saved $1.4 million of my own money. I'm happy to be "insulted" by people with more experience.
* use of dismissive sarcasm ("active imagination") to deflect legitimate concerns
* deliberate infantilizing tone ("budding social critic of your skill level")
* preemptive dismissal of differing viewpoints ("This comment will be downvoted but only by people who...")
* assumption of others' inexperience ("I assume you have never worked for...")
* defensive response claiming that you have the right to be insulting to others ("I'm happy to be "insulted" by people with more experience.")
If you honestly do care about how you come across in your communications and have a desire to use your interactions with others productively and not in a way which comes across as bullying, I am happy to work with you privately towards this goal. Is this something you would be interested in?
Honestly if you dressed it up a little you could probably charge quite a bit, it's just a matter of reaching that audience.
