Gunshot detection system iSAON (interactive sound analyzer on network)
The name iSOAN stands for “Interactive Sound Analyzer On Network”. It is SysNova's first generation sound detection system and it can be used to detect and report gunshots to a central station.
In addition it is also a complete area of rescue system and a mass notification system since each unit has a speaker and a microphone. The microphone allows two way conversation between the person at the central station and the person near the iSAON unit. Unlike other systems, the iSAON system uses RS-485, a robust industrial network that has a bus architecture and that can use fire rated cables. The cost of cabling of these units is similar to the cost of a fire detection system.
The goal of SysNova is to offer to the public for the first time a system that is in the price range of a ordinary smoke detection system. The cost per node is low enough for the customer to protect an entire building.
Since the evacuation and mass notification function is a natural extension of the gunshot detection, SysNova believes, that the two functions should be combined in one unit. The biggest part of the cost of a security system is the cabling. By combining the mass notification function (speaker), the interactive communication (microphone) and gunshot detection function in one unit, most of the cabling cost is saved.
The sound analyzer can detect gunshots as well as future sound that the unit has to be trained for. The unit uses a enough processing power for very demanding algorithms and the firmware can be upgraded at any time.
The iSOAN unit is offered in several packages. One package is based on a deep 7 inch square back-box (a 3d print of the box is shown on the picture) and has a acrylic glass cover where the speaker, microphones and the electronics are mounted. The picture shows the unit with the 4 Watt speaker. If the speaker is not requested, smaller packages can be used. A 4-wire cable is used for the cabling and each unit has an “in” d “out” connector.
