These still work great after 7 months. The motion sensors operate off battery but the alarm plugs into the wall. Very dependabe for use INDOORS. Have no idea how it would do outdoors. Very sensitive!

I purchased this originally about 10 years ago and it is still the best long distance alert. I have four gates that I use this on and can tell by the different sounds which gate is being opened and when my yard is being entered.I tried several different ones before but kept none worked as well or lasted like this one. I did not buy this to replace the original one, it still works great but a gardener damaged one and put it in the trash without telling me so now I need to replace it. Since it is so inexpensive I just went with the complete alarm system and I will give the rest to a friend. I have also purchased this for family members and all of them love it.
