innovative outdoor dual technology motion detectors


When planning an alarm system, be sure not to focus solely on detecting the intruder's presence inside the premises to be protected. Equally, and perhaps even more important, is to detect the unwelcome guest before he does any damage inside the building. For this purpose, devices detecting an attempt to penetrate the outer perimeter of the monitored premises are used. This functionality is offered by the latest SATEL detectors: OPAL and OPAL Plus.

  • efficient detection
  • easy installation and configuration
  • reliable outdoor operation
  • precise remote innovative configuration
  • reliable operation
  • anti-masking in microwave technology
  • small animal immunity
  • tamper protection against opening and detachment
  • high immunity to adverse weather conditions
  • can be used in building automation systems, owing to the built-in dusk sensor
  • selectable mounting type, owing to the dedicated ball-joint and angle type brackets
  • easy remote sensitivity configuration for all detection paths and dusk sensor using the OPT-1 keyfob (OPAL Plus)


automation systems
industrial halls

The OPAL series detectors provide excellent outdoor protection for buildings of various types and uses. These devices will also perform very well as indoor protection in industrial facilities, where difficult or special environmental conditions prevail (e.g. in halls, under umbrella roofs).

The OPAL Plus detector is additionally provided with a dusk sensor to control OC output, which allows it to be used also in alarm systems with home automation - without having to install any extra dusk sensors. The signal from the low-current output can be passed directly to the relay located in the electrical switchboard or to the home automation controller. The detector can also interface with the KNX system via a control panel of the INTEGRA series. Thus, the OPAL Plus functionality allows you to easily and conveniently control, for example, the roller shutters, exterior lighting of the building, garage door or entrance gate, as well as select the moment of operation through fine sensitivity adjustment.


Detection range

The OPAL series detectors are characterized by a detection angle as wide as 100 degrees and a range of more than 15 meters. Also, as the look down zone is protected, any intruder's attempt to sneak by to damage or pull off the device will be detected. In addition, the detector software has been designed so as to prevent triggering false alarms by the movement of small pets.

Immunity to adverse weather conditions

The OPAL and OPAL Plus incorporate PIR and MW technologies. The dual technology, combined with the algorithm of detector auto-adaptation to environmental conditions, ensures high immunity to false alarms and, consequently, stable operation in harsh weather conditions, such as rain, snow, sunshine and strong gusts of air. The ambient temperature changes are automatically compensated. Resistance of the detectors to extreme weather conditions have been confirmed by long-term tests. The devices offer correct operation within a wide temperature range from -40°C to +55°C.

Detector design

High quality of the OPAL and OPAL Plus detectors is a result of combining state-of-the-art technologies and many years' experience of SATEL specialists in designing and manufacturing of intruder alarms. Design of the detectors - both of their electronics and the enclosure itself - is the proof of this.

To manufacture the enclosures for OPAL detectors, the two-component injection technology is used. Through the combination of polycarbonate and thermoplastic elastomer, a splash-proof, IP54 rated design has been created. This enclosure protects the detector electronics against factors having an adverse effect on it, including rain, snow, fog or moisture. The OPAL and OPAL Plus detectors are also characterized by high mechanical strength and resistance to UV radiation, so the external appearance of the devices remains unchanged for many years.

Useful features and extras

Remote sensitivity configuration

A big help for the OPAL Plus installer is the function that makes it possible to remotely change sensitivity of all detection paths and dusk sensor using the OPT-1 keyfob. This makes the detector control easier and eliminates the need for repeatedly opening the detector enclosure to change the settings. The keyfob, supplied from a CR2032 battery, allows you to make several thousand adjustments.

Dedicated brackets types:


Ball-joint swivel


Mounting methods

Design of the OPAL series detectors enables them to be mounted directly on a flat surface, e.g. when the pet immunity option will be used. If, however, the detector needs to be mounted at another angle for the optimum coverage of the protected area, you can use the BRACKET C or BRACKET E set of dedicated brackets.

The ball-joint bracket, available in BRACKET C and BRACKET E, allows you to swivel the detector in two planes: up to 60° vertically and up to 90° horizontally. This makes it easier to find the optimal position relative to the protected area. However, if the premises require that the detector be set permanently at an angle of 45° relative to the wall, the angle bracket can be used.

The use of the modular bracket set (BRACKET E) allows distancing the detector from the wall surface - even by over a dozen centimeters - which will prevent limitation of the detection area by: cornice, external blind, cable gutters, lamp, gutter or wall unevenness. This holder also allows the detector to be installed e.g. on a soffit under the eaves of the roof.


For the devices to be installed outdoors, it is extremely important that safety and reliability of their operation be guaranteed. Therefore, the above mentioned brackets are designed so that the cable by which the detector is connected to the control panel is running inside them. As a result, the whole system is both secure and aesthetic.

Protective hood

Where the detector must be additionally protected against weather and soiling, the HOOD C GY. protection can be used. Installation of this protective hood is extremely easy - just mount it directly on the detector enclosure with two snap catches, without using any tools at all.

Tamper protection

No matter what type of bracket you are going to use, the OPAL series detectors will always be protected against being opened and torn off the mounting surface. This is possible owing to the two tamper switches located on the PCB and one specially designed tamper contact that can be mounted in the ball-joint bracket or on the detector back wall (if the angle type bracket is used).

Anti-masking in microwave technology

The OPAL series detectors are provided with anti-masking feature in the microwave technology. It enables them to detect the presence of any objects moving around in their immediate vicinity and thus prevent any attempt to mask them.

* for indoor applications


The OPAL is an outdoor dual technology motion detector, which is perfectly suited for application both on the outside of the protected building as well as indoors, where difficult or specific environmental conditions prevail (in halls, under umbrella roofs, etc.). The OPAL detector incorporates PIR and MW technologies, as well as antimasking function based on the microwave technology. The dual technology combined with the algorithm of detector auto-tuning to the environmental conditions ensures high immunity to false alarms and, consequently, stable operation in harsh weather conditions, such as rain, snow, sunshine and strong gusts of air. The device offers correct operation in a wide temperature range from -40°C to +55°C, the ambient temperature changes being automatically compensated.

The OPAL detector has a detection angle as wide as 100 degrees and a reach of more than 15 meters. Also, as the look down zone is protected, any intruder's attempt to approach the device to damage it or pull it off will be detected. In addition, the detector software has been designed so as to avoid false alarms caused by the movement of small pets.

Also the device enclosure is unique, as it is made using two-component injection molding technology. The result of it is a splash-proof IP54 rated design, which protects the OPAL electronics against harmful atmospheric phenomena. The detector enclosure is also characterized by high mechanical strength and resistance to UV radiation. For additional protection of the device against atmospheric precipitation and fouling, you can install the HOOD C (white) or HOOD C GY (gray) protective cover on the detector enclosure.

The OPAL detector is designed for mounting directly on a flat surface. If the detector is to be turned vertically or tilted horizontally, you can use special angle-type or ball-joint type brackets from the BRACKET C set (white) or BRACKET C GY set (gray), and also from the BRACKET E set.

To increase the detector's distance from the wall, even by over a dozen centimeters, it is necessary to use the BRACKET E modular set.

The OPAL detectors are available in two color versions: white (OPAL) and gray (OPAL GY).
