Ajax is smart, reliable, and lightning fast. It reacts to real dangers only, not to false alarms. If an event occurs, Ajax will notify you in a heartbeat.

Ajax has been designed and built from scratch by combining functional design, the latest technology and the best components available. This uncompromising approach made it possible to create a user friendly security system that provides top level reliability and functionality to security professionals.

StreetSiren is a wireless outdoor siren that deters intruders using sound and light. The device is triggered by detector activation with an audible alarm and LED strobe. Sound level and alarm length can be set in the mobile application. The device has IP54 dust and moisture protection. An optional 12 V DC external power supply can be connected to increase battery life.

The intuitive built-in accelerometer will raise the alarm if an attempt is made to remove the siren.

Ready to operate straight out of the box, the StreetSiren battery is already installed, therefore there is no need to disassemble the detector. With one click, it can be connected to the hub via the mobile application.
