Alarm sensors
This is an article well overdue, I forgot to write this information in here as my memory is not the best. So as I lay in bed, I can look into a picture and see a reflection of my living room and noticed that the sensor was blinking. This sensor tracks movement in the house (it's part of our alarm system) at first I thought that it might need a battery- but close inspection the next morning- it's wired through the house to electricity. So now, I am a tad worried.... What could have done this? I didn't see anything? I did hear some noises.. (Including last night I heard about 2-3 things that I couldn't explain) Anyway... just making sure that this is here.
