My landlord was pretty pissed about it and offered to help, but I don't think it is really worth it. I think she does a decent job otherwise with the place, and wouldn't want someone worse than her. I think her being a total bitch really helps her keep the other shitty neighbors in check.
What pissed me off is that it wasn't just a single unit motion detector. They are battery powered and signal a battery powered, hand held unit. There are three of them, and they are supposed to be used for hunting. You set them up in a triangle and which ever one is triggered, shows up on it's corresponding light on the receiver unit so you know which side the game is coming in. It was some start up company and the guy was selling the whole deal for an introductory price of only $25. I have no idea how to find the product again, or how much it would be to replace now.
