Picket/Palisades used to be the go-to fence in the UK. The issue is the two types, if you use the cheaper 2 horizontal bar top and bottom, they grab the fence and rattle it until the weld loosens then unscrew it or they use a car jack to spread the bar to crack the weld off and unscrew the headless bolt. You really need 3 bar palisade with a centre bar to help stop the spread / rattle attack. On either type, they can bend the top over to stop "feminizing" themselves and jump over.
The welded fence ( Prison mesh ) which is increasingly the default. It's a pain for them to cut and hard to cut and can look better if the colour is right.

Fence fabric being used in the electric utilities market is louver type. It looks similar to a cheese grater and is considered cut & clime resistant. To cut this type of fence you typically need a power tool and will take you several minutes. The fence also blocks the line of site when looking at the fence from angles.

Would have been happy to contribute to this article, especially to the intrusion detection part because so much is missing there.
Also not clear the emphasis on electrified fences, they are illegal in some places and definitely not the most popular add on anymore. Electrified systems are easy to bypass and honestly don't scare anyone anymore... all you need is a blanket or gloves.
Choosing a fence that is designed for security is important too, common mistake is putting concrete pillars along the fence, choosing a "good looking" fence or using a wooden fence. More and more people understand "stupid" fence is not stopping most people from breaking in and the most efficient way to have a true security fence is to have a sensor on it to indicate any cut or climb of the fence otherwise you can save the money on the fence because it's not going to stop anyone.

Our problem is not with intruders, but with insiders who want to steal stuff by throwing things out through the fence .

Opinions on landscape deterrence engineering/design (there is a specific, professional term for this type of engineering and that name escapes me at this moment), for instance: Spiny, irritating cacti/succulent kept to four feet high, planting progressively 'spinier/thornier' and taller foliage, up to 5-8 feet high (Agave??) close to the side of the house one's attempting to protect?
I'm asking particularly because there is a big push in our area of the City (the highest crime area for the last 4 years) to "use the landscape..." to 5-D crime (burglary, larceny, vandalism, home invasion), and a local businessman owns an incredible cacti/succulent farm on one edge of town.
If my question is too specific (sounds like I'm shopping) feel free to be as vague as necessary so I don't make anyone step on anyone's toes. There's an incredible air of respect in this forum, even among those who disagree, I don't want to tread on. Thanks for your time and consideration!
