Most people do it that way. Like this:
But there are also specific tools made for removing them that many tire shops have on hand. Like most things, anyone can buy them.
My sensors can be set to either 1 or 3 degrees of tilt. I don't remember what I have it set to, but I tested it and only got two pumps up on a hydraulic quick jack, not the sketch widow makers most wheel thieves will have. Every time I park, it waits 30 seconds for the car to settle and then uses that angle as it's current measurement. If it changes from that because the car is getting towed or jacked up, the alarm goes off and it pages me. My 850's alarm has 4 pain generators inside and 3 multi-tone 130 db sirens outside. Plus a back-up battery so if you remove the battery terminals, it still continues. Even if I don't come running, they are not going to want to hang around long enough to do anything.
