No false alarms
The body of the Ajax Button is designed to prevent false alarms, even if you sit or lie on it. To avoid further false alarms, you can put the Button to react with just a double click or a long press.

Ensures alarm delivery
The Ajax panic button communicates with a hub using the Jeweler's radio protocol over a distance of up to 1300 m. Once it sounds an alarm, you will see a blink of green eyes. The jeweler encrypts all transmitted data. In case of signal interference or radio interference, the Ajax system changes the radio frequency and notifies you, just like the security company, about the situation.

  • Signal range up to 1300 m
  • Command delivery confirmation
  • Encryption with a modified AES algorithm
  • Frequency hopping

Ajax DualCurtain Outdoor

AJAX DualCurtain Outdoor

Ajax DualCurtain Outdoor

Wireless Outdoor Bidirectional Curtain-Type Motion Detector.

It has two independent optical systems equipped with PIR sensors that allow different perimeter and sensitivity settings to avoid false alarms.

The Near Area Detection Technology, patented by Ajax Systems, allows the detector's upper PIR sensor to receive an additional viewing sector at an angle of 40 degrees down against the main sector. In this way it is possible to detect motion in the blind spot when a person enters the protected perimeter close to the detector.

It has an anti-masking and anti-destruction system. In case of equipment destruction, the Hub communicates to the central alarm receiving station and sends a notification to the user in less than a minute.

The installation and configuration of Ajax DualCurtain Outdoor is made simple through the app.

  • Motion detection speed: 0.3 a 2 m/s
  • protection class: IP54
  • Motion detection distance: from 4 a 15 m, depending on the settings.
  • Communication range with the Hub: up until 1700 m.
  • Frequency: 868,0–868,6 MHz
