Powersoft patents solar-powered weather-resistant all-in-one AV device
Published: PRODUCTS
Powersoft has patented a new technology that incorporates solar power with bi-directional wireless A/V communications.
The first product highlighting the potential of the concept is the Deva 1S, comprised of a power/control module and an interface module.
The Deva 1S can be used in applications ranging from background music to paging, in combination with video or audio surveillance. According to the manufacturer, ideal applications include national parks, outdoor sporting events, amusement parks, transportation hubs, construction sites, and rescue and safety situations.
Powersoft reports that efficiency was a key factor when designing Deva 1S, hence the incorporation of solar power, but the device is capable of running for longer than necessary in complete darkness.
Described by the manufacturer as providing ‘endless possibilities’, the Deva 1S is said to be ‘extremely efficient’ for long periods of operation and stand-by use. The high-capacity solar panel battery offers approximately 30 days of stand-by. A Class D amplifier is integrated into the unit to help support up to 40 hours of continuous audio playback, the equivalent of five days at eight hours a day. An energy-efficient white LED supplies optical signalling or lighting as video image support for up to five hours.
The power/control module consists of a solar panel, batteries, as well as processing, WiFi communication, and amplification. Meanwhile the interface module consists of loudspeakers, light, and optional devices such as camera, microphone and telemetric sensors.
WiFi communication is utilised 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 customised setup and operation, including the grouping of Deva units in zones where required.
Regarding the video or surveillance features of the unit, Deva 1S is configured according to a customer's specifications and connects via WiFi to standard equipment. It does not cost anything more once installed.
Deva 1S can be installed permanently or temporarily. Weather resistant moulded plastic enclosures are available in custom colours to match specific applications. Depending on hardware equipment and software setup, alternative configurations for specific purposes of Deva 1S are possible.
