yeah, sure you can.
So what's your point?
It is also possible to set your whizzo pro alarm with the front and back door closed but not locked, and all the windows open.
If you have a person who is in the habit of leaving their doors and windows open, they are making it easier for burglars. Are you going to claim that it is Yale's fault that there are careless people around?
If they have your whizzo pro alarm at ten times the price, and they leave their windows open, which have no sensor on them, the position is the same. So what?
If they have numerous doors and french windows and have economised on your expensive pro system by not having a door sensor on every one, then what?
If they have your expensive pro system, leave the back door open, press the "set" button and are through the door and away in their car without noticing that as well as the front door and hallway zones, there is another zone open as well, then what? The whole system will fail to set, which is even worse, since your burglar will not even get picked up by a PIR. At least they are better off having a Yale alarm than having nothing at all, which is probably their other alternative.
You're just finding excuses to whine about a low-cost DIY system not being the same as a high-cost pro system. Of course it isn't, dummy. We've had 20 pages of that, none of which is the slightest use to the OP, it's just anti-Yalers ranting again.
