Transmission performance
● At open places without interference, if the Device is
installed at least 1.5 m above the ground, the effective
communication distance is 100 m.
● In the environment without interference, the signal can
pass through a load-bearing wall, and the effective
communication distance is 20 m.
The actual wall penetration capacity is greatly affected by
network layout and actual environment.
