Description

The Dahua ART-ARC3800H-03-FW2(868) is a complete wireless alarm kit from Dahua’s AirShield series, built as a reliable, easy-to-install security solution for homes, offices, and small business spaces. The kit combines a central Hub 2 control panel with a four-button key fob, magnetic contact, and PIR detector for out-of-the-box protection.

At the heart of the system is the Hub 2 intrusion control panel, which supports up to 150 wireless peripheral devices in total, including up to 6 sirens, 64 PIR cameras (8 of which can be indoor PIR cameras), 64 remote controls, 8 keypads, and 4 repeaters — giving the Dahua ART-ARC3800H-03-FW2(868) genuine room to grow as security needs expand.

Network reliability is a defining strength of this kit. With support for Ethernet, Wi-Fi (2.4GHz), and 4G/3G/2G cellular connectivity, including dual SIM single-standby capability, the system remains online even if one network connection fails, ensuring alerts always get through.

Communication security is comprehensive, using the 868 MHz frequency band with AES-128 encryption alongside frequency hopping and two-way communication technology to keep every wireless peripheral connection stable and well-protected against interference or tampering.

Backup power is built directly into the hub, with a built-in lithium battery providing up to approximately 12 hours of operation during a power failure, so the system stays armed and connected even through extended outages.

Video verification is well supported too, with the hub able to integrate Dahua IP cameras for alarm video verification, letting linked cameras automatically transmit images the moment an alarm is triggered for instant visual confirmation via the mobile app.

Detection performance is strong across the included sensors — the wireless PIR detector offers a 12m, 90° detection range at a 2.2m installation height with animal immunity up to 18kg, while the wireless magnetic contact is suited for non-metallic doors with a maximum contact distance of 40mm, both with roughly 4-5 years of battery life.

Notification options are genuinely flexible, with push notifications sent via the DMSS app, along with SMS and call alerts to up to 5 phone numbers, plus arming and disarming available through the app, remote control, or a preset schedule.

Certification adds professional-grade credibility, with the system meeting EN50131 Security Grade 2, making the Dahua ART-ARC3800H-03-FW2(868) suitable for both residential and light commercial security deployments.

Altogether, the Dahua ART-ARC3800H-03-FW2(868) combines a scalable 150-device hub, multi-network redundancy, and reliable AES-128 encrypted wireless communication, making it a smart, dependable choice for homes and small businesses wanting a genuinely complete wireless alarm system.
