Cat vs motion-activated spray: who won?

Mandy and Olive are my two cats in this video. Mandy learned quickly that the spray bottle is "bad," so she avoided it. But Olive didn't give up that easy: she's the brave cat! Will Olive get past the the automatic, motion-activated spray bottle / spray-can?
Spoiler:
Out of the footage of video, I haven't any footage of her beating the barrier yet, but, while I wasn't recording, she managed to open the door and walk out of the cat room without being deterred by the barrier. That's why at 4:12 there had to be an oil gallon propped against the door to make it more difficult for Olive to open the door without being deterred.
In short:
The PetSafe SSSCat Pet Deterrent seems to be an okay product from what I can tell so far. Some cats such as Olive can beat it with their stealth because the motion detector seems to be set to a relatively high-motion threshold. Additional measures might be needed to more surely guard off areas of the house that are dangerous to a pet. The nice thing is if it's hidden behind a door, then it will somewhat help keep the cats from scratching at the carpet behind the door, yet will be out of sight and will not fire while the door is open because it's hidden behind the door.
