Home Security System Indoor Outdoor Weather-Proof Siren

We used this to monitor a ground-floor window where our A/C was installed. It never went off in error, but did work when the sensor was tripped. So, it works! I'm not sure I trust the ISM 415Mhz open RF, though - the unit could easily be jammed or triggered from an RF relay attack. So, use it accordingly. It does what's advertised.

Buen producto y facil uso.

This alarm system is really easy to set up and use, and the alarm Horn will wake up everyone, I really like it, and I have tried others, but some are just too complicated, so far it has been working very well, easy to turn on and off, I would recommend to a friend.

good im happy
