DAHUA WIRELESS ALARM KIT (ART-ARC3800H-03-W2 868MHz)

DESCRIPTION
Wireless Alarm Kit (Hub 2, Wi-Fi, LAN)

Supports alarm video verification through integration of the IPC with the hub.
Images can be remotely and quickly transferred from the PIR-Cam to the device.
Supports wired and AP network configuration methods, making it easier to add the hub to apps and switch to the hub’s network.
Supports multi-network redundancy for Ethernet and Wi-Fi to ensure the network remains stable and reliable.
Supports two-way communication and frequency hopping for stable communication with wireless peripherals.
Features cloud updates and allows remote updates of the device and wireless peripherals via the mobile app.
Offers a dual backup system with auto recovery when an update fails.
