MotionProtect Plus Fibra


Compatible hub models


Fibra communication technology

Proprietary wired communication technology. Fibra combines the reliability of wires with the freedom of radio connection.
It features:
  • Two-way communication.
  • Advanced anti-sabotage.
  • Instant notifications.
  • Remote configuration through an app.

Line connection

4-core cable

Fibra line length

up to 6,500 ft
When using the U/UTP cat.5 twisted pair.

Encrypted communication


Sensing element

1 × PIR sensor
1 × K-band microwave sensor
When the device detects motion, it conducts an additional RF scan to eliminate false alarms due to thermal interference: air flows, heated curtains and blinds, fans, fireplaces, air conditioners, and other likely sources of false alarms.

Motion detection distance

up to 39 ft
When installed at 7.9 ft height.

Motion detection angles

horizontal — 88.5°

Motion detection speed

from 1 to 6.6 ft/s
The direction of the detector lens should be perpendicular to the intended path of entry into the room.


3 levels
Sensitivity can be adjusted by PRO or user with admin rights in an Ajax app.

Pet immunity

up to 44 lb
up to 1.6 ft height

False alarm prevention
