Powersoft has patented new technology that incorporates solar power with bi-directional wireless A/V communications.
The first product showing the potential of the concept, the DEVA 1S, consists of a power/control module and an interface module. The power/control module consists of a solar panel, batteries, processing, WiFi communication, and amplification. The interface module consists of loudspeakers, light, and can include optional devices including camera, microphone and telemetric sensors.
“The DEVA technology has endless possibilities,” explains Thomas Mittelmann, Powersoft Business Development Manager. “Theme parks, sport venues, corporate and public facilities, transport hubs, emergency/rescue services, even shopping centers – they all experience difficulties distributing sound and surveillance over large areas because of the infrastructure it demands. DEVA is a wireless, self-contained, stand-alone concept that provides everything needed. It can be tailored to the exact requirements of an application and can be installed very easily.”
“Powersoft has always prided itself on its extremely efficient amplifier technology,” adds Claudio Lastrucci, Powersoft Managing Director and Head of R&D. “Efficiency was also the key when designing DEVA. Solar power is ‘green’ and freely available, but to keep a product compact, you must reduce the power consumption of everything running off it. The DEVA 1S is a fairly small device and capable of running for long periods of time even in complete darkness.”
“The same is true for the video or surveillance features of the unit. The DEVA unit(s) is configured according to the customer’s specifications, connects via WiFi to standard equipment, and does not cost anything more once installed.”
The DEVA 1S is extremely efficient for long periods of operation and stand-by use. The high-capacity battery, which is charged through the solar panel even in low light conditions, offers approximately 30 days of stand-by power.
The integration of an ultra-efficient Class D amplifier into the unit helps support up to 40 hours of continuous audio playback . An energy-efficient high-powered white LED supplies optical signalling or lighting for video image support for up to 5 hours. All of this is possible without recharging the unit.
Due to its compact dimensions the DEVA 1S can be installed permanently or temporarily. It can be mounted to walls or poles, allowing the power/control panel to be aimed at the sun and the interface module at the audience. Weather resistant molded plastic enclosures are available in custom colors to match specific applications.
WiFi communication is utilized for setup, upload and bi-directional real-time operation as well as real-time feeds for music or announcements. Playback of locally stored audio is supplied via an internal SD memory card. Remote PC software aids in highly customized setup and operation, including grouping of DEVA units in zones where required.
Depending on hardware equipment and software setup, alternative configurations for specific purposes of DEVA 1S are possible ie, for emergency services. Internal ports – Ethernet including PoE, USB – are provided for backup and peripheral devices.
DEVA units have an assortment of add-on options that expand the versatility of the unit including a video camera, microphone, FM tuner, GPS/GSM module and smoke, infrared or photoelectric sensors.
