Performance is good. It need qualified electrician to install.

### ⭐⭐⭐⭐⭐ BlackT microwave sensor alarm a good security choice
*by  on Reviewed in India 5 August 2025*

As there were several robberies in the compound decided to install BlackT motion sensor with a light and buzzer alarm. Over the past few weeks it has been working very well switching on when any one moves infront of it at night. Saved a lot as watch man not needed who any way goes to sleep anyway
