Central de alarme DAHUA ART-ARC3800H-03-FW2 868 – kit de alarme de segurança sem fios

Dahua Wireless Alarm Hub 2 is a central device that connects wireless sensors, PIR cameras and network cameras to provide alarm verification, communication and network redundancy. The hub supports image transfer from PIR-Cam devices and voice call alerts, and can be connected via wired Ethernet, Wi‑Fi (AP) or 4G for reliable operation and easy app integration.

Advantages

The hub enables alarm video verification by integrating IPCs with the hub and quickly transferring images from PIR-Cam devices. It supports voice call alarms, two-way communication and frequency hopping for stable wireless peripheral connections. Multi-network redundancy (Ethernet, Wi‑Fi and 4G) improves network reliability, while cloud update and remote firmware management allow updates of the hub and wireless peripherals. A dual backup system with auto recovery reduces downtime when updates fail.
