Single Direction Murena

Single Direction Murena New remotely controlled digital microwave transceiver from CIAS Labs

Murena is a new remotely controlled digital microwave transceiver from CIAS Labs, based on fuzzy logic analysis for outdoor protection as facades, balconies, terraces, entrances, etc. Murena generates two different radio frequencies giving the sensor the ability to detect changes in the phase of the signals, which vary dependent on the movement of the target and can therefore determine the distance from the senso.
The modulation of frequencies means that Murena is capable of detecting whether the target is moving in, moving out, static, etc., making a real target much more distinguishable from environmental disturbances.

  • Protects the façade, entrances, terraces ETC, of a building
  • Detect any intruders before they break in
  • Detect arrivals at a remote site
  • Can be used to cover different directions

Tech Features

Murena, thanks to the dual Doppler frequency generated, is capable of detecting distance, dimension and direction of the target making a real target much more distinguishable from environmental
disturbances. The frequency analysis carried out by a powerful DSP, (Digital Signal Processor), together with the fuzzy logic analysis, already successfully used with high level products like Ermo 482x pro and manta, provides an excellent identification of target and its classification in terms of risk with respect to the pre-configured parameters. The alarms are provided both by 3 solid state relays (alarm, tamper, failure), and through an RS485 port (plus version only).
(Frequencies available: 10.58 GHz, 9.9 GHz, 9.46 GHz and 10.525 GHz)
(MURENA-EG Frequency is 9.900 GHZ)
RF Output power (EIRP) = Certified in many countries and conforms to CE, USA and Canadian standards.
(MURENA-EG RF o/p power is 25 mw)


Any significant event is recorded into the events (history back-up) and into the characteristics of the received signal (monitors back-up). These events are provided with the date and exact time thanks to the internal “RTC” and can be downloaded through the special software WAVE TEST 2 used also in order to optimize the installation and give remote maintenance skills.

Sensor Features

The “Fuzzy Logic Rules”, which is based on the analysis of the signal, enabling the identification of the target and its classification in terms of risk compared to the configuration set. The detailed analysis of the movement provides an opportunity to understand whether the target is approaching, expulsion or, moving across, within the lobe of protection. Thanks to the fuzzy function SRTD (Short Range Target Discrimination), is able to discriminate the undesired movements close to the detector, such as those of small animals and/or birds that normally generate un wanted alarms.


The mechanics made by polycarbonate with UV protection, allows you to install the device in different environment conditions from -40°C up to +65°C.
After installation and adjustment, the optional protection kit MURENA-RS allows you to protect the access to the cable entrance. The special roof, which is part of this kit allows you to reduce the noise arising from the rain.
