  5.0 out of 5 stars Good, inexpensive alarm system

  Verified Purchase

  I bought two systems, one for the garage and one for the shed, and linked all the sensors to both sirens very easily, as shown in the kerui YouTube video. Now, if any sensor (door or motion) is triggered, both sirens sound, so that, even if one is disabled, the other will continue to sound and alert us.
  Sensor range is good and I had no problems with triggering the garage siren from the shed, even though it is an attached garage and the shed is 20m away and in the diagonally opposite corner of the garden.
  I'm not sure about battery life yet, but I've used rechargeable 9v batteries in similar alarms in the past and achieved several months usage, before a fresh battery was required. Fitting was easy using the sticky pads supplied for the door sensors, and screwing the motion sensors to the walls.
  Overall, very pleased with my purchase so far.
