We have a security system with a motion detector camera inside that will start recording when an alarm is triggered. Hopefully the alarm sound will send them off, but if not at least maybe they will be on video. And the video is sent over the web and stored on the security company web site so the thieves can't destroy that evidence.
May not stop them, but maybe will help apprehend them.
We had the alarm company come out to check on the alarm to make sure it was working, everything was working fine. When triggered it rings for 20 minutes and then re-sets and it would by pass the open doors when re-set but the motion detectors would catch them and it would go off again for 20 minutes. We have now come to the conclusion that John's sister didn't set the alarm in the house when she left on Friday. I'm really having a hard time keeping my mouth shut.
