Brings wireless detectors, sirens and cameras together in a single alarm hub.

This wireless alarm hub works over Ethernet and Wi-Fi and manages 150 peripherals and 32 separate areas from one interface. Two-way communication and frequency hopping keep the detector link on the 433.1–434.6 MHz band stable.

Key features

150peripherals

Wide wireless capacity

Connects 64 keyfobs, 8 keypads, 6 sirens, 4 repeaters and 64 PIR cameras to one hub.

8IPC channels

Video verification at alarm

Adds the image from the PIR camera to the alarm record and confirms the event with video.

32areas

Zone-based arming

Splits rooms into separate areas and arms or disarms each area independently.

12hours

Built-in battery backup

Keeps working through a power outage when fully charged.

AES128encryption

Protected wireless link

Two-way communication and frequency hopping keep the peripheral link stable.

50alarm messages

Offline cache

Stores alarm messages on the device when the network drops and sends them once the link returns.

EVERYDAY USE

Management from the appHandles arming and disarming through the app, keypad, remote control, card and schedule.

Uninterrupted networkRuns redundantly across Ethernet and Wi-Fi, and moves to the other path when one link drops.

Remote updateUpdates the device and wireless peripherals over the cloud, and falls back to the backup if an update stops halfway.
