Specifications

Type: wireless door sensor
Frequency: 868MHz
Control: temperature, charge, signal level

The Dahua DHI-ARD323-W2(868) wireless door sensor is a detector for monitoring the opening of doors, windows and other openings in security alarm systems. The device operates at a frequency of 868 MHz and uses two-way communication technology with frequency hopping for stable operation in conditions of radio interference. Built-in temperature and charge level monitoring makes it possible to maintain the system without unexpected failures.

Advantages

Reliable 868 MHz communication with frequency hopping — FHSS technology provides resistance to interference and attempts to jam the radio channel
Two-way communication — confirmation of delivery of the alarm signal to the panel and receipt of control commands
Radio signal level monitoring — monitoring communication quality for timely detection of zones with poor coverage
Low battery charge indication — advance warning of the need to replace the battery
Temperature monitoring — tracking the storage and operating conditions of the device
Simple wireless installation — mounting without running cables and drilling walls for wiring

Applications

Entrance doors of apartments and houses — the first line of security when arming the alarm
Windows and balcony doors — monitoring all possible entry points
Offices and warehouses — guarding service entrances, archives and restricted-access zones
Shops and retail facilities — alerting about unauthorized opening of doors during non-working hours
