I just had an Electrician install the light above my garage.
1) The lights were very bright. It did what I wanted
2) Camera was very clear
3) Motion detector work beautifully. Once you set the parameters.
4) The Siren was a FAILURE. You should remove it from the system. I had the volume on high and was expecting a screeching noise but barely heard it and I was standing in front of the unit.

Over all Iike the unit.
