The DJI drones look like they would be handy for observing your neighborhood during SHTF.

Assuming you have good neighbors and form some sort of neighborhood watch, how realistic would it be to use drones to patrol a perimeter?

How many drones would you need to keep something in the air constantly for, say, 8 hours? ( not daily, i’m thinking of one really bad day, or maybe a couple of bad days).

Do the drones need to cool down between flights?

Would three drones be enough?

Is the Mavic 2 Air the drone to get right now?

The flight time on most commercially made drones like that is around 20-25 minutes.  It's advertised as 30ish but real life is usually a bit less due to imperfect conditions. The charge time on the batteries is about 1.5 hours.

Consider that most drones have a flight time no more than 30 minutes and do the math.

Drones have their uses.  We have used them in woods fires and search and rescue.  However, I think continuous perimeter surveillance is out of the question from a logistical point of view.

You could do it with enough batteries and chargers but you would spend a LOT of time taking off, landing and changing batteries, to keep one in the air for 24 hours.

My mavic gets the full advertised flight time and charges really quickly with an aftermarket charger, it can also charge three batteries at a time.

Being up constantly is unrealistic, but keeping an eye out for something that you think might be coming is doable. I’ve used mine to check out approaching dust from a vehicle coming down my dirt road.

As others said .......


25m with decent flight time - you could fly at 10m/s the whole time, land, pop the battery out and go again (I think they have that capability, I know the phantoms did) so you just replace battery, and take off again, it's easy to get that down to a 1 minute deal.


You'd have to have 4 batteries ready to go in order to cycle in.

For super long loiter, fixed wing is best, but they're all 100% custom solutions, with DJI's there's many off-the-shelf solutions.

I LOVE my Mavic Air 2, the rage it gets w/ high video quality is absurd.

I guess what I was envisioning was a couple of guys in a backyard with lawn chairs and nothing better to do.

Seems like if you had a dozen or fifteen batteries and a few drones you should be able to keep one up....if that was your only “job”.

But this is speculation on my part as I have never flown a drone.

I think there is a lot to be said for the psychological deterrent value of drone flybys. I wouldn’t count on having a drone up at all times without a huge investment. Having a drone ready to launch and perform a quick recon/harassment/deterrent flyby? Now your talking

Cool.  I bet it's hell on batteries though.  Mavic wants to advertise as short a charge time as possible.  I am sure they could ship them with a super fast changer, it's not like they aren't aware that they exist.

They likely don't because it's going to murder the number of cycles that the battery is good for.

Technically, all you need is someone to swap the batteries and press a button to "go".  You can preprogram them with a take off, flight path, camera positions and landing.  You can then tell one to just run the script and it will go do it on it's own.

You can do this either programmatically, or fly the flight path once manually and have it record the loop for automation later.

I don’t think two guys with a few drones will be able to sustain continuous ops. Things will break.

Like someone posted earlier, a fixed wing with a programmed orbit would have better loiter time.

Sure, but would they be good enough for a few days, or a couple of weeks? I am hoping the answer is yes. That is why I was thinking three of the same drones,. They would have time to cool down between uses and even if one fails you have two more.

Seems like if the expectation is for a short term eye in the sky that can counted on for a few weeks...then these should be OK judging by some of the reviews I have read. I understand that these would likely not last long under hard use. But if it lasted for the duration of one catastrophe/shit-storm/incident I would be happy.

I guess I'm OK with the idea of disposable gear.

I have an old DJI Phantom 3 that still works fine.  It would of course burn up some of life on the motors in a shorter than normal time but they aren't junk motors to begin with.  I am sure they would serve your purpose fine. The batteries would probably give up the ghost before the motors failed you.

The Mavic 2 air is hot.  But for what you're talking about, even a Mavic Mini will do fine.  And while one drone can probably keep going all day like that as long as you're moving forward and keeping cooling air flowing in (not hovering all the time), you might want a spare drone just in case.

It takes longer to charge the battery than to drain it.  The controllers need to be charged, and your phone/tablet will eventually as well.   So, all in, to keep them going 8 hours/day, you'd probably need at least 4-10 batteries MINIMUM (depending on drone model), chargers to charge all the batteries at the same time (which means aftermarket chargers), and 2-3 controllers.  You're talking a good amount of money there.

2 people could do this.  One flying, one communicating and helping swap batteries/controllers/drones.  Shoot, one person could do this, if you can stand another bit of time during each return/land/battery swap.  Actually... given that they'll return home and land on their own, maybe not.  Tell the thing to return home, set down the controller, and get everything ready for when it lands.

Yeah, the return to home feature and programmable flight paths with waypoints seems like doing a simple perimeter patrol would be a piece of cake judging by what ive seen on Youtube.

I also read that they updated the firmware and now the mavic air 2 has a zoom feature.

I ordered two of the Mavic Air 2 Fly More Package, six extra batteries on top of the six that will come with the drones...12 total.

I should probably get more chargers and am also thinking about the smart controller.

Debating getting a third one.

Pay 200 extra and get the fly more kit, comes with 3 batteries. We've run them back to back a few times and the drone doesnt seem to care. It's got decent heatsinking onboard.

I'm yet to note how long it takes to charge a battery, that would dictate how many batteries you need. I guess if you want guaranteed 8 hour coverage, but 2 with fly more kits and 10 more batteries. That is 16 batteries total at 30 min per.

I guess that whole setup would cost less than 3k, but compared to a helicopter or satellite it's a steal

The multi-battery charger from DJI only charges one battery at a time, at least for the Mini.  Fstop labs makes a charger that charges 4 batteries in parallel.

The one time I had a battery too hot to charge, I pointed a small desktop fan at it for something like 5 minutes, and that cooled it plenty.  Keeping a small fan blowing over the myriad of batteries in chargers that OP is talking about would be a good idea, keeping batteries cooler during charging helps longevity.

Just try to do a compass calibration while hanging from the side of a cliff and the Electronic Chinaman tells you to step 3.whatever meters away from all metal objects.

First of all, it's in fucking meters, fucking communist units of measure.  Second of all, the fucking metal things are what's keeping me from falling to the fucking ground.  And, there's a third of all, that I'll recall after the present rage subsides.  And probably, a fourth of all.

I have the Mavic Air 2.

It's a solid drone. I usually get about 25 minutes of flight time. I could push that a few minutes longer but it would be perilously close to an empty battery when landing. I like to land at about 15%.

The nice thing about the MA2 is that the last software update added zoom capability and now at 1080p you get a 4x zoom which still looks pretty good.

In a SHTF situation, where are you going to get the electricity to charge the batteries from?

If you want to spend a couple grand you can goto a tethered drone

They even have hybrid gas/electric drones that will do a no shit 1-2 hour flight time.


These are big fuckers though.  Like 1 meter between props and probably 30+ pounds with 24-30 inch props.

Check out Foxtech.


Otherwise like others have said, plan on 20-30minutes tops.

I have a palm sized FPV drone that can do 20 minutes.   Get it about 50 feet off the ground and you are unlikely to hear it.   Been out 3/4 of a mile with it and half a mile with my IR night camera equipped micros.

I may or may not have flown one of my night time FPV rigs half way down the block from inside my home.  Then parked it inside the large package mailbox and then waited for a car to drive.  Only then dod I relaunch to come out of the mail box and chase it down the street at street gutter level while practicing getting in close for the license plate.   Flys better without the ducts I designed and weighs far less.   With 3.5in props and a LiPo I can get under 250g.    Running with LithiumIon I get almost 3 times the flight time and have it setup to switch between a daytime and nighttime camera.


My bigger stuff, meaning 10-13in props will do around 18-25 minutes on lithium ion batteries that build myself.    Eventually I want to play with secondary cameras that have a 6-8x magnification lense on them with a downward tilt to see if I can get stand off capabilities for actually looking at things.

I also have a frame that is huge at 1.5m on the diagonal between motors.   It is meant for 22-24inch props and would take 4 of my large packs for either a 12s 50v system at 12ah or it would be a 6s 24v system at 24ah.   Goal with it would be to hit an honest 45min flight time while carrying multiple cameras and some real weight.

Aren't DJI products still well known for having to "phone home" to check if they're allowed to take off at a given location? I've seen where you can "unlock" a certain area to allow the drone to take off but supposedly only after registering with DJI's service and it allowing you to do so. In SHTF, when they could just turn off the manual override system, would it even allow you to take off?

Every drone related SHTF or security thread seems to always include a "if you value freedom / privacy, don't buy a DJI" warning similar to not using Windows 10 or your cellphone for anything "sensitive".

In SHTF, when they could just turn off the manual override system, would it even allow you to take off?

Every drone related SHTF or security thread seems to always include a "if you value freedom / privacy, don't buy a DJI" warning similar to not using Windows 10 or your cellphone for anything "sensitive".

Show me an $800 drone that can fly up to 42mph, for 25 minutes, shoots 4k video at 60fps and 1080 up to 120 240fps and has 48mp camera.

The sad fact is that there are no USA made drones under $5,000 that can do those things. Even Skydio, which is twice the cost of the MA2 uses a host of Chinese built components.

Plus the DJI drone DO use some USA built component from Texas Instruments.

I have a Mavic Pro.  Lasts 20-25 min or so.  I jailbroke it which allows you to change flight characteristics - I can hit almost 60mph but it kills battery fast.

Would work good for quick missions but all the taking off and landing, people will find you.

The FAA can blanket shut those down. You won't even be able to takeoff. Even worse if you live near an airport. Basically a paperweight unless you get away from local airspace restrictions and have internet access (unless that has changed). Other than that, they are amazing drones.  But for shtf, look for something not as "smart".

Laughs in LAANC authorization, which allows you to fly in controlled airspace, including adjacent to airports.

And no, the FAA doesn't have a kill switch that can shut down all drones. They just go arrest you if you made an unauthorized flight in controlled or restricted airspace.

Not if you want ready out of the box...

But my 7in fpv drone has hit 23minutes flying at a constant 40mph and has none of the nannies that come with a DJI.

The issue is that you have to build it yourself and it isnt a flying tripod.   You actually fly the thing.

You can use other firmware like INAV to have waypoints and a position hold but it isnt as locked in as a DJI flying tripod, something DJI does VERY well.

It will get a bit more expensive as an "all in" when it comes to getting controller/goggles/chargers/etc to go FPV.   But the knowledge and true abilities can be quite substantial.


My 13in FPV drone cruises at 50+mph for 18 minutes.   Once I take it to a lithium ion 32v, pack instead of a 24v pack, it will likely either gain time or gain speed.    On 32v LithiumPolymer it hits 80+mph.

Another poster above already asked this but I too am interested.

Is there an off the shelf fixed wing available that someone could recommend, or even a build it yourself kit?

Preferable features

I want it to have the ability to fly a programmed route.
Fly in up to 10 mph wind.
Decent range.
Ability to carry a normal and a thermal camera that can pan & tilt.

The fixed wing drones are still expensive.

My Mavic Air 2 can do the first 3 on you list. Would have to upgrade to the Mavic 2 Enterprise or Phantom 4 RTK to get the thermal camera.

I've flown my MA2 in sustained wind up to 20 or so mph. with gusts a bit higher. Eats up the battery and it isn't as steady it it's doable.

Patrolling?  No way. Checking out hotspots and recon of high ground before you make the hike up? Absolutely.

I like the idea of sending up a balloon. I would make the recommendation of hanging an insta360 instead of a mavic or GoPro. Insta360 no shit gives you a view in every single direction simultaneously, and is ultra rugged/water resistant out of the box.

The short answer is yes for building it yourself.

The long answer is you will need likely 6 months to a year of flying it and getting experience with software like PixHawk, Ardupilot, or Inav.

Expect several complete losses while learning before you ever get brave enough to try to put an IR or thermal camera on it.

Rctestflight on youtube has been building variants of solar powered fixed wing craft for about 2 years now.    He has a lot of duration builds that run off Inav from a ground based 3D printed rover to a 4-6 hour duration FPV wing.

The knowledge base is out there.

Hell I think it was LAbushman that was here on the site with his Dehogaflier(youtube it) and doing thermal night cam guided pig hunts back around 2013.   To do what he did took a fairly sizeable ground station and decent knowledge.  He was getting FAA attention for monetary gains from stupid Youtube ads if I recall which is why he stopped posting videos.
