One bar — low signal strength. Stable operation is not guaranteed.
Crossed out icon — signal is missing. Stable operation is not guaranteed.
The following factors affect the signal strength:
The number of devices connected to one Fibra line.
Cable length and type.
The correctness of the wire connections to the terminals.
Check the Fibra signal strength before nal installation of the detector. If the signal
strength is as low as one or zero bars, we cannot guarantee stable operation of the
device.
Motion detector detection area
When selecting detector placement, run a
detector. This test allows checking the operation of the device and determine
the sector in which the detector detects motion.
The location of the detector determines the area to be monitored and the
effectiveness of the security system. When selecting the installation location,
consider the direction of the detector lens, its viewing angles, and the presence
of obstacles to the view of the lens.
The detector can recognize motion at a distance of up to 12 metres. The
direction of the detector lens should be perpendicular to the intended path of
entry into the premises.
Vertical viewing angle of the detector
detection zone test for the motion
