DHI Start Kit ARC3800H 4G
Dahua ART-ARC3800H-03-FW2(868) is a complete wireless alarm system built around a central hub with support for up to 150 wireless devices – including sirens, PIR cameras, remote controls, keypads, and repeaters. The system is designed for easy installation in homes, offices, and small commercial properties, offering flexible connectivity via Ethernet, Wi-Fi, or mobile network (4G) with dual SIM card support.
The hub can connect up to 8 IP cameras on the same network and can pre-record alarm video directly in the hub – meaning the camera does not need its own SD card. Upon an alarm, notifications are sent via app, SMS, or phone call to up to 5 phone numbers, and the system also supports two-way voice communication with an integrated siren for verbal deterrence on-site.
The kit includes a PIR motion detector and a door detector, both with a battery life of up to 4 years, as well as a key fob with a battery life of up to 3 years. With a security rating according to EN 50131 Grade 2 and AES128 encryption, the system is certified for professional use while being simple enough for private individuals to install themselves.
