The StreetSiren from Ajax Systems, the most awarded wireless security system in Europe, is a Wireless External Siren used for loudly notifying you of an alarm during detector activation. It's best installed externally to warn of danger or to deter intruders.
Not only does the StreetSiren warn of danger or intrusion, but you will also be notified as soon as the detector has been activated with an audible alarm. The alarms are customisable so that you can alter the sound level and alarm length within the mobile app. Also, the built-in accelerometer will raise an alarm if anybody attempts to remove the siren.
Simplicity is key, the StreetSiren is ready to operate straight out of the box: the battery is already installed, meaning there is no need to disassemble the keypad. With just one click, it can be connected to the hub in the smartphone app.
A required authentication means your system is prevented from forgery as well as including a tampering alarm, jamming detection and communication channels encryption.
