I purchased an inexpensive motion sensor which is battery powered (9V), small and has a very loud piercing alarm. I mounted is inside my security
(storm door) door so it can't be tampered with but monitors the walkway in front of my house. It has gone off 2 times during the night hours and woke
me up. I did not see anyone but by the time I got to the window I think a person would have ran away because it is very loud.
I like the unit because it is inexpensive, small, easy to install, loud, and battery powered. The alarm goes for about 10 seconds, then resets. I
found it at Home Depot in Chula Vista for about $20. I looked for it there to buy another one and they were out of them so I hope they restock it. I
have used it many nights and I don't think it has any false alarms but it has to be aimed above the ground level so cats won't set it off. I learned
that early on. I'm not at home so I can't report the brand name of the unit. It would be nice to be able to use one made by Claymore, but I can't
do that anymore. |
