It's not the initial cost, but the upkeep - licensing, vaccinations, food, exercise, etc. etc.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Yes, the walking will be healthy for you, without having to pay for a sport-school. And not so long ago most dogs ate leftovers from the table. No idea what a license may cost over there though.
While a camera may record anything as evidence, a dog may work even preventive; some people are afraid enough to not even come close to the fence.

I can vouch for the big scary dog design. We live next door to a 40 acre public park and have problem with drug dealers (& other idiots) every few years. Early on we had an 80-90 pound mutt that looked like a Rottweiler. We got the reputation for owning Cujo[^]. Sadly he died several years ago, but don’t tell the drug dealers that! 
These days I’d suggest a Chow Chow[^]-German Shepherd[^] mix. The shepherd should give the animal good intelligence. The Chow Chow should make it very loyal to you/your family. I’ll need to be very strict with the dog as it grows… know exactly how you want it to respond and train it as a puppy. We did this with a beautiful brindle chow-shepherd mix that was loving and very playful. But look out if she didn’t know you and you walked on our property… she’d put the fear of God in you!

I live with dog alarms - scares the #$%$%^ out of anyone on my front porch that makes the mistake of pushing the "make dogs go berserk" button. Humans call it the door bell. USB cameras don't pee on the carpet either.
Shop around newegg or the like. What you want is a battery powered motion sensitive camera (or two). If you have a power source, then so much the better. I don't know if your porch is your entrance or the back, but I bought the ring video door bell for the wife. Catches all sorts of critters on my front porch - bats, lizard, large moths and children who come home too late

Just get something like YawCam[^] and an IP camera.
I wanna be a eunuchs developer! Pass me a bread knife!

Or on the same idea but cheaper you could get a regular webcam, a very long USB cable (20 meter did it for me) and the free software ispy. With that in minutes you can program the soft to record any noise or movement it detects.
I had some issue with someone messing up with my bike and it helped a lot.

That raises an interesting point: what's the USB distance limit?
I'll have to search the Interwebs.

Don't have the sort of camera/recorder that detects motion by comparing one video frame with the last. That sort is totally useless for outdoor use. One that I know of triggers on every raindrop that goes past at night, when the built-in IR floodlight gets refracted straight back into the camera, every bird that flies past in the day and every leaf that waves about in the wind, day or night.

Better off doing that using motion in linux on the Pi. The camera support on the Pi in Win10 was not the greatest when I looked at it.

Pepper spray? No: use Raid Wasp Killer. It'll shoot 30 feet and stop 'em. Works well on raging dogs too.

For the easiest way to set up a Raspberry Pi as a motion camera, I would highly recommend MotionEye OS:
Home · ccrisan/motioneyeos Wiki · GitHub[^]
He has customized the OS so the RPi acts as an appliance; all you have to do is flash the SD card and it's ready to go. To make configuation changes, you type in the internal IP address using another computer and you get the web-based login screen, and after logging in you can tell it how long to save recordings, whether to take still shots long with video, etc. You pretty much do all your interaction with it using the web interface, not the command line.
It's based on Linux and not Windows IoT, but you won't notice the difference anyway because it just sits there and does its thing and the only time you interact with it is to look at recordings or change its configuration.
For mine, I use this camera:
http://www.waveshare.com/rpi-camera-f.htm[^]
Unfortunately I put my camera inside a waterproof housing and the night vision infrared would reflect off the housing glass, so I had to remove the infrared bulbs, but during my initial tests the night vision worked great.
If you wanted this as a project to learn and tinker on, then Windows IoT might be fun to try, but if you just want to set it up quick with minimal headache, MotionEyeOS is the way to go. I'm saying this as someone who started out doing it as a fun project, and I had grand plans of writing my own custom scripts to move the saved recordings around, but after a couple of fruitless days working on it, I got to a point where I just wanted it working, and MotionEyeOS was the winner.

forego the pepper spray and get a taser.
itza one shot deal, but effective.
|
|
|
|

Tasers aren't 100% effective, but they might be lethal. The effectiveness of pepperspray depends on the pepper. Internet has some cool video's that show people eating those things and regretting it seconds later.

Wasp and Hornet spray for getting rid of wasps and hornets, is said to be as or more effective than pepper spray due to the range of 25 feet with the Wasp/Hornet spray as opposed to pepper spray. I've had no experience with it but would be worth a little research. I would think it cheaper also.

"Tom Tomorrow" is the nom de plume of Dan Perkins, an editorial cartoonist: [^]. Link to .png graphic imho safe-for-family, and not inherently poltical.
«There is a spectrum, from "clearly desirable behaviour," to "possibly dodgy behavior that still makes some sense," to "clearly undesirable behavior." We try to make the latter into warnings or, better, errors. But stuff that is in the middle category you don’t want to restrict unless there is a clear way to work around it.» Eric Lippert, May 14, 2008

Three things happened when I wrote this[^] article.
1) During the process of writing it, I discovered a momentarily significant news event (I think it was an earthquake, but not sure anymore) that I didn't know about because I hadn't read the news that day yet. I found that interesting, as a means of obtaining very realtime "information."
2) Reading a random sampling of the posts (you can mouse over the keywords and get samples of the posts) I realized how inane people are. I mean, we all know twitter is inane, but really, just how absolutely, incredibly, sadly, horrifically inane the people who use twitter are, and by inference, the "baskets" of people who also do not use twitter.
3) My immense disappointment that given #1, where #1 could be really amazing actually as a technology to inform and disseminate not just information but creative and interesting thoughts as well with the potential to lead to real social/political transformation, #2 kills it because, well, that is not what people do.
I think technology like twitter and facebook are metaphorically the canary in the human "mine" / mind, and the canary is definitely being asphyxiated. They illustrate why, (and this is not confined to the US), Trump has close to 50% of the vote and Clinton talks about "baskets of deplorables."
(As you said, not inherently political, I was just using politics to illustrate the suffocation of cute little yellow birds.)

As Terry Pratchett, Ian Stewart, and Jack Cohen put it in The Science Of Discworld, we are not Homo Sapiens (the thinking man), but Pan Narrans (the storytelling ape). That is why a good fantasy trumps the boring facts.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.
