Bunnymummy 0 Report post Posted July 20, 2011 (edited) Hi all, I am looking to buy an inexpensive but very loud door motion sensor that I can place across the backyard corridor. It needs to make a very loud chime (e.g. DING DONG) like the ones at 7-11 doorways. Reason is because I feel that there is a security risk because the common backdoor corridor leads to a aircon ledge that someone might be able to climb into my backyard via the window (no glass or grilles provided by condo developer). If I have a motion sensor then at least I would be able to hear it if anyone is approaching the area. Other good ideas welcome... p.s. I can't install grills there cos I have to hang my laundry using a ceiling mounted sliding laundry rack. Edited July 20, 2011 by Bunnymummy Share this post Link to post Share on other sites
