Only works properly for a week and then lights continuously (same day!)

Having recently faced a burglary attempt, I bought this sleeve over an alarm system and remote video surveillance, to go alone. The socket has actually worked well for about a week (it was lit at night regular intervals - I saw it on my video-surveillance that would send me a picture message whenever there was a change of light) .

However, after one week, the bush was not working and remained lit even the day time! Hello the bill! When I got home, I turned off and on and there it seemed to work again.

I think she has a program that should last maximum one week, and after it becomes normal socket ... It's still a big design flaw. I sent it back and Amazon refunded me with no problem.
