Review on πŸ”’ Dahszhi Dual Laser Detector Alarm Beam Sensor: Indoor 300m & Outdoor 60m Infrared Detection for Optimum Security by Paul Wilson

Revainrating 4 out of 5

Works as described

The product installs quickly after studying the instructions carefully. The person who wrote the instructions lacked basic English skills, but after some introspection I was able to decipher the intent of the installation guide.

Pros
  • Applications: Excellent for installation in a security system in a school, office building, hospital, home yard, etc.
Cons
  • Questionable purchase for the elderly
