Bests & Worsts Reviews from Amazon

Due to all of the crime that we have experienced, I have security cameras that let me watch once our property has been breached. I was over it! I found this beam type IF Red device and installed it thinking I would call police as a crime was in process.. 2:40am Sat my chime woke me. I picked up my device to see what was up...Nothing. Wondering what set it off, I went to the DVR the next evening. This is what I found. At 2:38am a Moving van/Uhall slowly stocked the neighbor hood. It passes my house, I can still see it parked at the corner due to the lights on the back roof of vehicle (brilliant move by thieves). I wait. Then a subject appears, checks the passenger door on the vehicle parked in front of the house on the street, walks up to check ours in the driveway, but he must notice something. It looks like he checks it out, steps over the IF line, sees the red light flash and decides to leave, checks the driver door of the vehicle in the street and goes on his way. Had he not have seen it, I would have been able to see him approaching then call the police. Yeah for this little device....Worth the $99.00 for sure.
